Third Person's POV

Issei falls to the ground, kneeling next to him was Rias, having her outfit completely shredded, showing off some of her skins under the torn shirt and skirts. Both of them was extremely exhausted after fighting against Bartholomew Valefor.

The man stared at both of the young devils with an unimpressed expression on his face. "The power of the Welsh Dragon is a power to be feared. Nonetheless, your ability pales in comparison to the real dragon that we had fought in the past before it was sealed by God and Maoh."

Issei looked towards Bartholomew, feeling anguish while narrowing his eyes towards the Old Devil with great hatred and fury. "You don't belong in this world!"

"It was not by my hand that I was saved by my comrades...unlike the Gremory, who abandoned us during the midst of battle...To stay alive, I was summoned by humans who wish to pay me tribute."

"'Tribute'?! You steal men's souls, and make them your slaves!"

"Perhaps the same could be said of all religions."

"Who the hell do you think you are?! WHY DID YOU DO THIS?!"

Valefor only gave him a cold stare in his eyes, sending a chill up his spine. Never had Issei felt an intense look in his entire life. He knew that he faced someone who is extremely stronger than him, but never had he felt the sheer intensity that was given by the Old Devil. He pulled his fist backwards before lunging forward towards Rias with an intent to kill. The red-haired princess eyes widened before placing up a magical barrier but was completely fell after one powerful punch by Valefor.

Issei jumped in-between them, blocking the full force attack with his teeth completely gritted. He was then sent back followed by Rias who caught the male in her hand as they rolled to the ground, injuring them even more.

"Protecting your King...What a noble way to die..." Valefor commented as he slowly made his way towards the downed Red Dragon Emperor.

"My brother believed in me..." Issei spoke up, feeling the pain coursing through his body. He felt extremely worn out with every punch being given by the Last Valefor. Yet, he still determined to beat the living shit out of him. "Despite everyone calling me a member of the Perverted Trio...Despite him being the strongest out of both of us...he never looked down on me. He always told me that I could get stronger...And when I was killed, Rias gave me a second chance at life, even though I became a Devil and awakened my Sacred Gear. Every time, when everyone needed my help, I was always too weak to do anything about it! But, if you even think about taking away either Rias, (Y/N), or anyone else I care about away from me...I'LL FUCKING KILL YOU!"

Valefor stared the young male before raised his hand upward. "Such a bold statement...I'm impressed. You bring yourself such authority even at the hand of Death...Farewell, Welsh Dragon Emperor..."

"ISSEI!" Rias shouted, reached out for her Pawn.

Issei closed his eyes for the impending strike from the older devil...yet it never came. He opened his eyes and noticed the man struggling to bring his hand down. He widened his eyes in shocked, before tracing back onto the man arm...It was caught in chains...

"Do you always need to be in the receiving end, Issei?" The Red Emperor Dragon turned his head towards the voice. His saviour was walking towards them, feeling extremely furious and determined to beat the living hell out of Bartholomew. Blue flames bursting out of his left eye, releasing a powerful demonic aura throughout his body.

Valefor stared at the man with the same stoic emotion before being pulled away from Issei by the chains in his arm. "To think that it'll only take your brother for you to finally to show yourself...This makes me wonder...what really makes you tick off, Cipher?"

"..." (Y/N) didn't reply, standing near his brother, wrapping around the chains in his arms as a gauntlet silently. Coming out from the door nearby were Kurumi and Dipper, looking exhausted as they quickly took a breather at the side.

"You shouldn't just run off, asshole!" Dipper shouted, feeling annoyed by his 'Master'. "Besides, you just recovered from all of those beating!"

"..."

"So, you're that bastard that kidnapped, my darling~" Kurumi prepared her a flintlock, looking at the Last Valefor with every intent to kill him. "Such a pity for you to come and-"

Dipper raised his hand in front of her, stopping her from advancing. "Stand down Kurumi..."

"Why~?"

"It looks like it's going to be personal..."

She widened her eyes at his proclaim before turning her head towards both of them. She noticed the intense staredown by both of the male, setting the sense of danger in the area. Rias and Issei also noticed the change in atmosphere in the room, cold dead silence as all of them stared at the two powerful devils in the room, staring at each other with a dark eerie aura surrounding them.

(Y/N) slowly approached Bartholomew as the white-haired male breaks the chains in his arm. He rubbed his arm, feeling the slight strain in it after being forced to be pulled away by the new Dream Demon.

"Will you be alright without that sword of yours?" Valefor calls out. "Because without that...it'll be over before you know it..."

(Y/N) Hyoudou wasn't intimidated by the comment as he kept on walking towards him. "I survived your 'hospitality'...Fighting against you is no difference..."

"Oho?"

"(Y/N), his power!" Rias calls out, earning the attention from the (H/C)-colored boy. "He can manipulate ice around him!"

"...there's more to that..." He muttered before changing the flames in his eyes in red. He held out his fist, intending to have an all-out fist-fight with the Valefor. "So...where is your weapon?"

"Oh, you're talking to me?" Valefor took the response as joke, giving the Dream Demon a sinister smile on his face. He held out his fist, coating it with ice. "I really want to hear the sounds of your bones make when I grind them to dust..."

"Hmm...Gotcha. You're going barehand as well...but I think you'll regret that later. Besides..." (Y/N) brings his fist up to his face. "All I'm here for is you. To hell with your heresy! You're nothing but a blight on mankind."

"What is a man?" Valefor spouted before narrowing his eyes, sending out a chilling aura once more. "A miserable little pile of secrets! But enough talk!"

In a blink of an eye, Bartholomew appeared in front of (Y/N) with his face pulled back. The man stared into his eyes with a cold stare, "Have at you!" (Y/N) narrowly dodged the punch, resulting in a powerful gust of winds flew past by his head.

"W-What is that?! That is entirely different than any punches that he had given to me!" Issei commented, looking at the force exerted by the Last Valefor were more powerful than before. "It's like he was....holding back..." He stared at the fight as his brother trying dodging every attack made by the Old Devil. He looked in horrified, feeling extremely worried by his brother. "...Fuck..."

"Issei, what did you mean that he held back?!" Dipper inquired, confused by the statement made by the younger Hyoudou.

"How...can he keeps up with that power?!"

"Oh...not bad," Valefor commented as he backs away after giving a lightning-fast jab. He then followed with a faster punch with (Y/N) dodging the hit once more, with a room to spare. The Old Devil continues to sends out the punches, as it began to become faster with every punches given, turning into a blurred mess as the Dream Demon keeps on dodging.

"He is throwing those jabs like there's no tomorrow!" Dipper commented, amazed yet horrified by the Valefor fighting capability. "B-But (Y/N) continues to evade every single one of it!"

The Dream Demon swayed his body side-to-side, avoiding the attacks from connecting to either part of his body. As the punches continue to gather speed, going absolutely insane with the amount of the punches given. But it does not phase him at all, (Y/N) leaned his body backwards, avoiding another punch by Valefor.

"Hmph..." The white-haired devil smirked as he raised his right leg towards the younger male for a powerful kick as his leg was coated with magical energy.

(Y/N) responded by quickly jumping over the kick as quick as possible, shocking older Devil as he swing his leg forward, sending out another powerful gust of winds, creating a huge cut on the floor. Everyone widened their eyes in shock from the impact made by the Last Valefor.

"T-T-T-That k-kick!" Rias shivered in fear, looking towards the deep cut on the concrete floor made by a single kick of a devil. "Is this the true power of Valefor clan!?"

"That...that power...it's unlike the other devil, I seen! It's even on par with Vali...no...even greater than him!" Issei looked at the

Bartholomew put his leg back to the ground as he turned his back around, looking at a crouching Reincarnated Devil in front of him, feeling slightly annoyed. "You really are something...but you ain't beating someone if you keep running,"

The Dream Demon slowly stood up, as he looked back at the devil. The white-haired male were shocked when the once blue flames in his eyes immediately turned black. (Y/N) gave him a sinister smile of his own. "You don't need to tell US that!"

"CIPHER?!"

"Well~, for starters..." (Y/N) hopped for a bit before rushed forward, directly in front of Bartholomew, going for a lightning jab coated with black flames. "How about this?!"

'Those moves!' Valefor thought as his cheek was grazed by the fast-moving punch.

"Oh? Not bad~ In that case," The (H/C)-colored boy immediately followed with a barrage of punches towards the Old Devil in front of him without breaking a sweat. "HERE I COME!"

"W-Wait a minute!" Issei was flabbergasted. Never would he see his brother moving extremely that fast. But more importantly, "H-H-How can he control that form?!"

"It seems that our plan works," Dipper smirked as they saw Valefor trying to dodge the punches, being the one in the defensive side. "(Y/N) made a contract with Bill Cipher,"

"Huh?"

"He's quite a stubborn one to be sure,"

(Flashback)

"Are you for real?!" As Dipper carrying the weakened (Y/N) towards the direction of Issei's fight. The boy has a brown-haired male looked at his 'friend' with an angered expression on his face. "(Y/N), you can't go back and fight the man who've kidnapped you!"

"N-No...this my fight-" He tried to argue but was cut off by his Pawn.

"Look, I know that you trying to fight him out of anger...but you can't just burst in the room with your remaining strength. The only thing you can fight is a twig-"

"Like you?"

"That's not the point! I know that your brother can defeat h-"

"No, he can't..." (Y/N) immediately told him as they kept on walking towards the dark hallway. "At first I thought his power is based on temperature manipulation...I tried to fight back a little but my flames were dimmed down by him in the second."

"I can't believe that no one in the ORC knows about the REAL ability of Valefor Clan..." Dipper sighed as he kept on dragging the Dream Demon. "The sword should've and the dart should've given away their status. It's a miracle that they survived."

"So, what now?" Kurumi chimed as she walking by their side. "Neither of us in any condition of fighting anyway...I used a lot of my time power just to recover both of our health...Dipstick is useless since he has zero training. No offence by the way,"

"No, I'm with you...Look, we just had to bail alright..."

"...I can help..." Bill showed up in front of them, stopping them in their tracks. (Y/N) looked at him, feeling agitated by the future idea coming from his mentor. "You know that it's the only way..."

"...So you had to fight at the cost of your life? It's my fault. If I hadn't been so weak, we wouldn't be here."

(Y/N) was stopped by the real Dream Demon with his collar being pulled by it. "Your friends are risking their lives to save your ass! You can't just mop around and be the damsel in distress! Man up, kid. Their lives depends on you! So, you better well accept the damn deal...remember this...The only thing necessary for evil to triumph..."

"...is for good men to do nothing" (Y/N) finished the line as he saw Bill's hand reached out for a handshake as his hand burns into blue.

"Shake on it kid..."

(Y/N) was hesitant. He didn't know what to do. He felt a lot of pressure being put on him as everyone depending on his decision. The (H/C)-colored boy looked up...accepting the handshake as the flames covered both of their hand as it turned black.

"Let's bring them nightmare...one last time..."

"Very well..."

(Flashback End)

(Y/N) let out a smirked as Valefor continue dodging the rapid punches until a single solid punch hit the white-haired male face. Without hesitation, (Y/N) continues to let out blinding punches to the face multiple times, as the Old Devil continues to felt the pain in his face. Staggered, the man moved behind a little as his vision was getting blurry.

"But wait," (Y/N) announced, winding up his leg backwards. "There's more~"

"What?" The man questioned before being hit by a powerful kick in the midsection, sending out a powerful blow to gut thus sending him flying away.

"Oh dear~ That looks painful," Kurumi commented sadistically as the Duke of Valefor looked at (Y/N) with anguish look on his face.

"You...." He gritted his teeth, feeling incredibly annoyed by the Reincarnated Devil.

"I'm going to put an end to this," The Dream Demon announced as he readied his fist up once more.

"Ever the insolent devil..."

(Y/N) noticed that Valefor is getting into strange footwork as the Bill told him in his mind, 'He's building up momentum, kid! Watch out!'

"I know..." (Y/N) responded before Bartholomew starts to moves at a very high-speed. (Y/N) observed the situation, his eyes trying to follow every movement of the Duke of Valefor himself before reacted to another powerful sidekick from Valefor, who were shocked by the reaction speed. The Dream Demon follows up with chains covering his legs as he goes for a roundhouse kick, sending the devil away to the throne, destroying it.

"His reflexes and strength have gone tremendously high" Rias pointed out as they observed the fight between the two devils. "He even was able to move as quickly as the Duke of Valefor himself. It as if...Valefor was fighting himself this whole time!"

"I don't really want to do this, you know?" (Y/N) spoke out, earning their attention. "But you threatened my friends and kidnap me...so...stand down, old man."

"Ha...ha...hahahahaha!" Bartholomew cackled under the rubbles of the throne as he pushed off the debris on him. He slowly stood up from the ground, looking at (Y/N) with a calm yet annoyed expression on his face. "Such arrogance from a reincarnated devil. Very well..."

"What is it now?"

"Well, Cipher..." Valefor began to wind up for a powerful punch as demonic energy began to build up in his right hand. "Can you follow this? Let us find out..."

"You shall regret those words." (Y/N) nonchalantly replied as he readied himself.

Valefor quickly moves forward...as if they were in a stopped time. The man goes for one last punch...a powerful punch that said to be stolen from the Chronos himself...it is...if the rest of them could see it...

...tick...tock...

It's...

...tick...tock...

...the fist...

...tick...tock...

...that...

...tick tock...

...Surpassed...

...tick...tock...

Time!

https://youtu.be/vit9OVyUiB8

"MUDA!" (Y/N) screamed, giving a powerful demonic punch coated in flames, colliding his fist to the cheek of Valefor in blink of an eye. "I like this...Thanks for the lesson, old man."

Without any explanation, everyone immediately saw a body lying on the floor as (Y/N) standing tall with smoke coming out of his hand. The boy took a glance on the male as the chains of his makeshift gauntlets break into pieces, falling onto the ground with a satisfying clink.

"Huh?" Dipper got extremely confused by the display in front of him. "What the hell just happened?!"

"Valefor...has been beaten?" Rias blinked her eyes, completely flabbergasted.

"N-No way! Are you for real?! W-What just happened?!" Issei began questioning, confused yet happy that his brother defeated the Old Devil into submission.

"That's why I warned you..." (Y/N) called out, dusting his hands. "That you'd regret it...right?"

(With Yusuke and Mordred)

Yusuke charged at a worn-out Karel as the sword in his hand was incredibly beaten and nearly broken. The blue-haired swordsman slashed down with his katana as Karel backs away from the attack. At the moment, Mordred ran pass the Knight of Cipher with aiming for a swift stab with Clarent in her hand. The long-haired swordsman blocked it with his broken sword before it shattered into pieces.

"Pretty boy, now!" Mordred called out as she moves away.

Yusuke sheathes his katana inside the scabbard, concentrating his demonic energy into blade. In a blink of an eye, Yusuke appeared behind Karel, his blade was pulled out as the once clean sword has been drenched with red liquid it.

"Secret Sword...Morning Star..." A bright flash appeared as the blood gushed out from Karel's chest. The swordsman gritted, slowly losing his vision. He turned his head towards the Knight of Cipher with a glare. "Y-You're all g-going to..."

"Fail? That is unlikely," Yusuke wiped the blood off his blade before sheathing into the scabbard once more. "My past self isn't a pushover no more...Karel..."

"To think a yokai like you..." Karel coughed, blood coming out of his mouth as he kept on bleeding. "Strike me down!"

"...I will not dirty my blade once more....You already deserved of what you did to me...Farewell," Yusuke walks away as Mordred followed him from behind, leaving the crazed swordsman laughing like a maniac before falling down to the ground, losing consciousness.

"Dark history?" Mordred inquired but didn't receive an answer from the older male as she placed her sword back to its dimensional storage. "Figures...let just find-"

They were then greeted by a dark, powerful aura coming from the castle. Both of the once confident swordsmen immediately began to shiver in fear. They felt their energy being taken from them as Mordred lose her footing and fall to the ground, onto her knee.

"W-What was that?!" Mordred questioned, looked towards the older male.

Yusuke felt disturbed towards the intense aura made by the people inside the building. "I...I don't know...(Y/N)...he's fighting Valefor..."

"That d-demon...is that strong?"

"I...I don't know...it's even more powerful than Kokabiel...It felt disturbing...It's like my power suddenly being sucked out by...by...oh no..."

Yusuke's eyes widened in realization, fearing for his leader and friends' life as he noticed the rise of the power.

"No...No...NO! IT CAN'T BE!"

(With Raynare)

Raynare was leaning down on one of her knees as Yashiro standing over her, cracking his knuckle. "I've got to say, no one has ever been able to last this long against me..." Yashiro chuckled, as he grabbed her by her hair, forcing her to stand up. "Especially a Fallen Angel who's never had a single ounce of training."

"I said shut up!" Raynare pulled her fist back and punched him in the chest with all of her strength. Once she did, Yashiro began to chuckle like an idiot before immediately laughing all over her attempt. He looked at her with an overconfident expression on his face, bringing her face to his.

"Is that the best you got? It didn't even faze-"

He felt a sharp pain entered his chest, noticing a small smirk on her face. He looked down as blood started overflowing from his mouth. He began to stumbling backwards as he saw large and dense light spear formed inside on his chest.

"I told you..." Raynare staggered a bit from being released by the big man, sweat dripping from her forehead. "Being too overconfident could get you killed..."

"D-Damn it," Yashiro fell forward onto the ground with blood overflowing from his chest. "T-To be b-beaten like this....by a low....class....Fallen Angel..."

Raynare sighed, feeling extremely tired yet relieved that she survived the fight. Closing her eyes, she began to fall back to the ground. Her vision getting blurry before she started to faint on the spot.

(With Orion)

Both of the Reincarnated and Half-Demon clashes their weapon, creating more and more cracks on the floor with each impact made by the weapon. Cy gripped the handle of his sword tightly as he began to force the sword downward but Orion used his strength to push the sword sending his foe away. Orion then goes for another downward slash before being blocked by Cy.

The sheer strength of the Half-Titan creates a bigger crater under him before Cy cries out in pain. A crack of bones can be heard as dark swordsman dropped his blade to the ground. He fell down to his knee with blood pouring down from his now broken legs. He raised his head once more, noticing the point of the Campione near his face as Orion aimed the golden sword at him.

"It's all over Cy..." Orion said as he began to breathe heavily. "Surrender...it's the only choice you have..."

"...This is just...a flesh wound..." Cy tried to pick up the Sword of Attila from the ground before Half-Titan slammed his leg onto it.

"Just stop...we should end this fight..."

"Fickle...you and the rest of your pantheon are fickle beings...All of the wrongdoing...all the wrong decision made by your kind ruined other people lives...That's why none shall ever pray for your kind ever again!"

Orion stared upon the kneeling man, narrowing his eyes towards the swordsman. "Your ideology is not wrong...the past may not change but it's the present we must hold up high...From the black past of our mythologies, there is a glimpse of light. You strayed away from it and dwell into the darkness far too long..."

"Heh...is that so?" Cy smirked before sensing the dark presence coming from the inside of the castle. "Huh, it's the finale..."

"Hmm?" Orion looked at the downed knight in confusion as he felt the slight change in atmosphere. Not just from the castle, but the entire area as the dark presence of a devil appeared out of nowhere. "What is that?"

"That...is Lord Valefor's true power..."

Orion gritted his teeth, knocking the knight out from consciousness before rushing towards the inside of the castle.

(With Tyrion)

Both Tyrion and Yamazaki were engaging in an ultimate fist cuff as both of the male sending out multiple kick and punch towards each other. Both have dealt a certain amount of bruises on their body with Tyrion sends out a powerful kick that was dodged the bigger man as he goes for a counter uppercut.

Tyrion was launched into the air before guarding an upward whip attack by Yamazaki. Tyrion channelled his lightning ability into the pipe in his hand for a downward slam as the crazed man dodged the swing but was caught off guard when the boy loosen his grip on the pipe, twirling around to the side before swinging it to the midsection. His power coursed through the pipe, stunning Yamazaki in his place.

The Lightning Rook continued his assault as he began to hit him a knee to the face, a swift jab to the chest and a couple more pipe swing that keeps on stunning Yamazaki in his place. The man tried to block the attack as he goes for another counterattack but was caught off guard once more Tyrion twirled around as electricity began to gather around his arm.

"GET OUT OF MY FACE!" Tyrion shouted as he unleashed a powerful uppercut infused with electricity, creating a miniature whirlwind to the ground, launching the bigger man up to the sky before he came crashing down to the floor, injured by the attack.

Yamazaki was knocked out by Tyrion last attack as he dropped the bent pipe in his arm, completely throwing off his tattered outfit away. He wiped out of the blood from his mouth. Looking back at the man as he started to pondered about something. He shook his head to get off the thought before feeling the dark aura coming from the hallway as he turned around in response.

"This energy..." Tyrion mentioned, immediately leaving the room.

(With Kokichi)

The Ink Demon effortless trying to tires out the Dainsleif user as he kept sending out ink monsters towards the swordsman. Llyod kept on slicing down the ink monsters as they keep on coming. Kokichi took the advantage, covering his arm with ink and turning it into a hammer. He goes for an upward smash Llyod brings his sword down to block the incoming attack but was parried by the purple-haired devil.

The Ink Demon pulled him another arm back as ink covered his it, turning into a gauntlet before going for a devastating attack to the gut. Llyod caught up blood as he was sent back a couple of feet away. Stabbing his sword to ground, he manage to keep his footing as he stare down towards the younger male.

"You pretty strong aren't you?" Llyod wiped the blood coming from his mouth.

"I make do with my abitliy~" Kokichi responded as more sharps tentacles coming out from the ground, aimed at Llyod.

The Dainsleif user took out his sword from the ground and readied his stance as both of the male rushed in towards each other. Lloyd goes a straightforward yet swift side swing towards Kokichi who slides through the attack he sent out the spikes towards the blond-haired swordsman as he quickly turned around to cut it down. Unfortunately, some of it manage to reach his limbs and stabs into it. Bloods pouring down from multiple parts of his body before the man cut down the rest of it.

Kokichi jumps forwards with his arm changed into a scythe as he goes for a downward slash. Parried the blade with his own as he forced his bleeding arm for a punch to the Ink Demon. Unbeknownst to him, the ink was stuck in the sword, with Kokichi forcing himself to be weakened by it. From the momentum of the swing, the Son of Azazel dodged the blade before going for a powerful clothesline that twirled his opponent around in the air, releasing the sword from Lloyd's hand.

The Knight of Valefor falls down the ground as he started to lose conscious by the blood loss from his stab wounds. He took a glance of the boy clad in white before closing his eyes, fainted and bleeding on the ground.

Kokichi gave out a sigh of relief as he looks upon the sword in his hand. "I'll keep this as prize..." The boy smirked as taking the scabbard from the fallen swordsman on the ground before stopped in his tract. He felt a sheer amount of pressure coming from the castle as he turned around, incredibly terrified by the aura given by a devil.

(With (Y/N) and everyone else)

(Y/N) turned his head around in shock as he felt the spike in power coming from the fallen Valefor. Everyone eyes widened as the man slowly stood up from the floor. Bartholomew released more dark energy coming from his body, sending chills to the New Devil as they stared upon what seems to be a devil with his head turned 180 degrees away from them, standing tall with his powers channelled.

"I'm not done yet..." Bartholomew announced coldly, giving off the feeling of hatred and anguish as he gripped his fist tightly. The man put his both of his hands around the dislocated head before twisted it back in position, hearing a loud crack that could bring people down to their knees, horrified by the view.

"He...twisted it back!" Dipper commented, traumatized by the action made by the Last Valefor.

"What in the living hell is he..." Rias was extremely terrified, wondering if that Valefor had been holding back ever since they got here.

"Don't go pushing yourself old man," (Y/N) said summoning back the chains into his arm for a makeshift gauntlet.

"You don't need to tell twice, Cipher. Now I see that your casual speech wasn't just for show." Bartholomew rubbed his neck as he then raised his finger, earning their attention. "But, you've piqued my interest now...this old devil has one thing, he'd like to ask you..."

(Y/N) raised his eyebrows in confusion as the Valefor pointed his finger at him before saying, "I can't feel the flames of hatred towards me within those two eyes of you..." They all looked at the Dream Demon, confused by the statement made by the Duke of Valefor, questioned his real motive. "So, tell me Cipher...what's the real reason you're here to fight?"

"This is because I can't allow you to leave here-"

"Not you...him!" (Y/N) was cut off during midsentence as he realized on who he asked the question. You have ever been the ally of humans. Have you forgotten what they did to you?"

(Y/N) closes his eyes before reopened it, giving Bill a brief moment to control his body. "Think you I would forget such a thing? No, "

"Then, why exactly you sided with humanity? All they do was a waste of space in this world...constantly killing each other for their selfish desire! Like what they had done to me..."

"There's a thought for me to take revenge of this world," Bill started speaking out. "...But slowly, I do not want to seek revenge against them anymore. This boy...(Y/N) is like a family to me and changed my perspective on how I should preserve them. Hatred? Revenge? I don't need any of that anymore...There is no reason why. Is there any man that needs a reason to protect his own family?!"

'Heh...not bad...thanks anyway...' (Y/N) thought, feeling incredibly happy to be acknowledged by his mentor, the original Dream Demon. The moment felt spectacular as both of them as sync with each other.

"Still uttering the same nonsense," Valefor gritted his teeth, feeling slightly angered by the thought of siding with humanity. "Away with your humanity!"

"...You really should've just stayed down..." Bill let out a sighed. The Dream Demon then raised his fist up, gripping onto the makeshift gauntlet tightly as (Y/N) took control of his body once more. "This next hit will kill you!"

"...Seems like bluffing won't work anymore..." Valefor unbuttoned the clothes as he slowly removes his attire. "I'll admit it...you're both a strong one..."

"...So you'll surrender? In that case-"

"I was foolish...I was foolish to think...I could win like this..."

"!" The host of the Dream Demon was shocked as the devil revealed markings on his body started to glowing.

https://youtu.be/A0rkfT6R4pM

"I would have preferred not to do this...since it tends to backfire me...but it's the only way..." He then released a lot of demonic aurae, while screaming in agony. The extreme pressure to his body began to show as the marking started to grow even bigger covering his pale-skin. The rest of the devils except for (Y/N) felt like their energy were sucked away by the demon as they fell to the ground, feeling extremely tired.

"I...I can't move my body!" Issei shouted, feeling weakened by the sudden power burst from the Last Valefor. "This felt...even worse...that Vali's...No..."

"Wait, are you telling me...His power-" Rias was cut off by her 'lover' as the man narrowed his eyes towards the powerful devil as his body began to covered in dark flames.

"You just noticed..." (Y/N) called out. "He has the second variation of Divine Dividing...the Duke of Thieves..."

"Y-You're kidding..." Dipper stared in utter shock, feeling useless as the Valefor kept on screaming in agony until a burst of flames covered him entirely.

As the flames died down, Bartholomew stepped out of it, with the marking burning into his entire body as the energy around him being pulled into the flames, fuelling the rage and desire of the Valefor.

"Behold my true form and despair!" Bartholomew, the Duke of Thieves announced as he stood proudly. One could hear them scream as they held back the overwhelming power inside the flames. It was as if something malevolent had just been born onto the world. And the one to seize the initiative...was once again, Bartholomew!

The Duke of Thieves rushed forward with incredible speed. He gave his hand pulled back with a condensed yet stockpile magical energy, compressing the muscles in his arm. Valefor would simply direct that power into his fist and release it in one intense blow. Its simplicity makes it the strongest strike...

"True Demonic Fist!" Valefor shouted as black flames began to burst out of his, as it came flying towards (Y/N). The Dream Demon barely dodged the punch as it burnt his cheek slightly while giving Bartholomew his own direct punch. Without faltering, Valefor follows up with his left hand. Once again, (Y/N) forced his body to dodges the strike while returning another punch, this time towards his head.

Valefor's ignored the impact of the punch toward his head as he prepared for another punch. He goes for a right hook which was once again dodged as (Y/N) returned another punch to the face. And from there, it keeps ongoing...Bartholomew keeps throwing off more punches towards the Dream Demon while the young devil keep on countering it with his own punches. The impact of the punch creates more and more cracks on the floor even the walls and ceiling where effected by the collision between this two powerful devil.

As if he was being possessed, the Dream Demon keeps on swinging like a maniac with each punch hitting the burning body of Duke of Thieves. It was then until...

*drips*

(Y/N) stopped his rapid punches as he stared towards the ground. Blood? Why there's blood on the floor? Which immediately hits him...his nose began to bleed as the red liquid flow down it like a river. The realization hits him, he started to overheat...He felt that his strength began to be weakened because of the flames of Valefor's body started to siphoning his energy. Albeit, he started to lose control of his power. He knows those punches were intended for a one-hit kill...

...

He slowly began to lose conscious...

...

He saw one singular, devastating punch coming towards him at high-speed velocity. He tried to move but his body started to worn out...he can't move a single hit.

...

He closed his eyes, waiting for the incoming impact...

...

...

"You pushed your body to your limit just to avoid death! But I'm still here to take your place!" The black flames in his eyes burst even harder as the boy dodged the death blow as he gave him another solid punch to Valefor's face.

The Duke of Thieves' glanced towards the boy as he noticed that Bill Cipher has gained control over his host body once more. Seeing through the technique of Old Devil...his host's nervous system is in an unimaginable amount of pressure as Bill struggled to keep up with the incoming death punches by Bartholomew. Bill felt the extreme pain coursing through his host's body as the muscles began to start burning from the excessive move.

Everyone noticed the slight change motion in the fight, yet no falter to give a comment nor interfere with the intense battle inside the large room of the dark castle. Every hits echoes to the big room as Bill. It was only a matter of time before they were brought to that moment. They regained their footing with Valefor going for another devastating kick which collided with Bill. And so...in spite of the fact that mere graze may be fatal, this two combatant keep on unleashing rapid barrage. Bill will not falter, he kept on returning each blow for blow with his ability, even if his life started to drain.

Those two fighters stood in the room, continuing to weave their fists together. Raising the stakes to their limit and at the sight of such a beautiful dance...everyone in the room found themselves resonating as one. Glistering sweats and the multiple drops of blood flying through the air as both of the fighter keeps on throwing the ferocious punches to each other, with Bill trying to keep up with the Last Valefor.

Amid the fervour that taken in the room...

...

...the first to foresee the resolution...

...

...was none other...

...

THAN BILL CIPHER HIMSELF!

Bloods began to flow down from the holes in of (Y/N)'s head. Bill slowly beginning to feel the pain as he looked down to look at himself...However, from out of nowhere, Valefor gave a solid punch to the face, sending Bill slightly back. The direct hit from Bartholomew Valefor finally connected with (Y/N) Hyoudou tried to shrug it off by regaining his balance...unfortunately, another fist collided with him in the form of an uppercut. Valefor continue their dance of blows....Only now, the tables have been turned! Bill has been pushed onto the defensive, guarding himself from the mighty blows of Bartholomew, trying to withstand the sheer impact with his now weakened body. His energy started to deplete rapidly...but Bill kept on standing tall.

"Wait (Y/N) is...(Y/N)!" Issei shouted in fear, worried by his brother.

"It's taking all he has to block Valefor's attacks..." Dipper bites his lips, feeling agitated by the outcome of this fight. "It looks like he started to lose control of Nightmare Form...no...It's not (Y/N)...It's Bill!"

Bill received a powerful kick to the ribs as blood spews up from his mouth. He keep on receiving the more punches by Valefor as all of his friends began to fall into despair, Bill Cipher thrust into darkness thought...

'Please...stop...' A saddened voice can be heard inside the mindscape. Bill closed his eyes, his vision getting more blurry. For the first time, he felt the feeling of dying...relatively, he never thought of it as a feeling, rather an annoyance...but now...it felt nothing more than regrets and despair...He could not fathom how he received such a feeling...Heh, it's probably from hanging out around with those people.

'Sorry kiddo...this is the last stretch of the fight...I can't force you to do this...' Bill smirked under those arms, covering those punches. 'Heh, if I weren't saving my energy back then...I'd dissipated your gizzard into electrons that they...but...I guess your life isn't that bad...(Y/N)'

The moment he said that (Y/N) felt the connection between him and Bill beginning to loosen up as the mindscape around them slowly shattered. The older Hyoudou didn't know how to respond as tears began to swell up in his eyes...no...it already have flowed over his face as Bill kept on blocking the attack coming from the Devil.

'It's alright...don't cry...they'll protect you...I'll protect you...I'll make sure...to beat anyone that tries to-' He was caught off guard by a direct hit to the face by Valefor as the devil tried to plunged his head to the cracked floor...but...Bill took one more grasp at the thread of victory, grabbing onto the silver-lock of Bartholomew. The Duke of Thieves was shocked by the display, feeling the slight pain as the Dream Demon painfully grab onto hair, before pulling his body nearby...showing of a tired...yet chilling smile from Bill Cipher.

"What?!" Valefor shouted in pain, grasping onto the lock of Cipher.

"Found you~"

"You took the hit on purpose just grab me?! Are you fucking insane?!"

"No...I'm a Demonic Space Dorito..."

Bill let out a roar of his life as both of them started to punch each other in a very close quarter. Each individual collided onto their body. They kept on delivering those punches, collecting bruises onto their body. The chains began to slowly crack as blood began to fall on the floor. Before they knew it...neither of the devil was able to utter a word. Those who had recently joined was amazed by the fight as they can neither move nor act to the situation. And amidst that painful silence...only the groaning of bone and flesh could be heard...and those sounds reverberated across the room.

Until...

Finally...

Those sounds came to an end too...

Bartholomew Valefor were sent flying across the room as Bill Cipher stood tall with the fist is still in the air. Everyone were surprised by the outcome as they stared upon the downed devil to the other side of the room. The walls started to crack before crumbling to the ground behind them. The sunlight began to rise upon the land.

"B-Bartholomew Valefor..." Dipper eyes widened as he slowly stood up from the floor, regaining a little bit of energy that is left in his body. "Has been brought down to the floor!"

"It's over..." Kurumi muttered before everyone in the room cheered happily. The latest batch of Cipher Clan picks up the rest of them on including Issei and Rias on the floor.

"Hell yeah!" Issei cheered happily, raising his gauntlet high up. "Nice one, bro!"

"As expected from my beloved," Rias giving them a smile.

The only one that didn't cheer was Dipper as he noticed something is wrong.

The sunlight shines through the nook and cranny of the room, hitting upon the body of the older Hyoudou. The brown-haired boy eyes began to widen in shock as he noticed a smile on his friend's face.

"Hey, kid! You did a..." Orion stepped forward before stopping his track as he noticed something odd. His expression changed in realization as, his smile dropped, his eyes widened like a plat as something surprising...no...a wave of emotion-filled his entire heart as he fell down to his knees, unable to comprehend such view. Everyone began to notice the change in atmosphere as they looked at the half-titan confused.

"He..." Dipper muttered, but still can be heard by the devils as they turned their attention towards the Reincarnated Devil, who is frozen in his face..."He's dead..." Everyone stared upon the devil in silence as yellow dust began to fly out of the male's body. The news hits everyone like a storm as they were absolutely petrified, throwing them off balance. "Bill Cipher...the Dream Demon..." Rias stared at (Y/N)'s, filled with fear as Dipper shouted spoke out the cursed word once more, "IS ALREADY DEAD!"

"Hmph...you only just realised?" Everyone turned their head back towards the direction of the voice. Valefor slowly sat up, looking worn out as his marking on his body began slowly but surely fading. Bartholomew Valefor was still alive, albeit, seriously injured by the fight.

"What did you do....WHAT THE FUCK DID YOU DO?!" Tyrion exclaimed, filled with mixed emotion. Anger? Sadness? Confusion? All of it appears on his face.

"He'd already passed on...well before I dropped...But, even then, he still wouldn't bend a knee. No, if anything...Even in Death...He just kept on swinging..."

The chains in (Y/N)'s hand broken off as it falls back to the floor, immediately shattered into pieces. "Hey, Cipher," Valefor called out as he raised his head towards them the boy. "Seems like you managed to put this devil flat on his ass...You and host is one hell of a demon..." With that, a magical circles appeared under with a different marking other than his own clan. "It looks like my time is up...what a shame...Heed my advice (Y/N) Hyoudou, don't let your friend died in vain...be strong as next time, I'm not holding back any punches..."

And with that, a blind light covered his body as Orion lunged forward for a solid powerful punch...but it was too late...the Valefor already vanished from the area as the Half-Titan creates massive craters on the floor. Orion gritted his teeth in anger, clenching onto his now bleeding fist.

"YOU BASTARD!" Orion yelled, unable to forgive the Duke of Thieves for what they had cost them. He turned his head back towards (Y/N) as the Hyoudou body separated with Bill Cipher as both of them dropped on the ground.

"(N/N)-san!" Asia ran forward, quickly tending the injured Hyoudou, but the boy insisted on limping towards Bill who is slowly crumbling into dust.

"B-Bill..." He whispered, trying to hold onto the last remaining ounce of life within Cipher. He continues on limps towards the demon as everyone stared at them.

Mittelt looks away, unable to see the pathetic display in front of her, tears starts to pour down of her cheeks before being comforted by Kalawarner, who tried to hold onto her tears. Pyronica hesitated to help (Y/N), unable to act on behalf of Cipher himself. This is the second time she has seen Bill Cipher gone through this process...but somehow...she felt the sense of sorrow, looking down upon them. An air of melancholy surrounding them as they stood up looking at both of the devil, who had tried their best...but unfortunately, fail to prevail...they began to sink into despair.

(Y/N) reached Bill's hand, to grasp it one last time, holding onto it like it was the last thing he ever held on. The Dream Demon looked back at his host ...His friend...his family. After all this year of abandoning his entire family to wreck chaos...he finally found peace...From a human nonetheless...

"No..." (Y/N) held on Bill's hand tightly. "Don't go..."

"Huh...it's alright...(Y/N) Hyoudou..." Bill smiled, letting go of the grasp before punching the boy chest lightly. "We'll meet again...don't know where...don't know when...But I know we'll meet again some sunny day...~"

"Keep smiling through..."

Crack

"Just like you always do..."

Crack

"'Till the blue skies drive the dark clouds......far away..."

"Your singing...." Bill slowly close his eye, dropping his hand to the floor. "...sucks..."

And with that...Bill Cipher shattered into pieces, turning into yellow dust. Being blew away by the wind as the room filled with only silence for a couple of minutes. (Y/N) stared to the ground, tears dripping to the ground. Everyone in presence mourn over the death of one of their friend.

This morning....is filled grief and sadness...

To Be Continued
