(Y/N)'s POV

"I'm glad that all of you are safe." Rias said with a concerned expression on her face. She hugged both of me and Asia tightly. "Are you injured?"

"All three of us are safe, Buchou." Issei reassured him. "Besides, there's no way Irina going to attack his boyfriend."

"Oi!" I got a tick mark on my forehead, glaring at my twin brother. I then looked at Rias with a small smile. "Don't worry Rias. We go way back. Even though I almost got sliced in half by that blue haired chick, but we become friends."

"You just love to annoy her judging by the way you speak." Issei sweatdropped.

"And thus, you are right." I agreed with him while shrugging my shoulder.

"After the normal club activity, I was called in by Sona and was listening to the story about people related to the Church intruding the town." Rias explained with a serious expression on her face. "And I also heard that they have a Holy Sword with them."

"That's why I felt Holy Aura coming out of them." I nodded my head before snapping my finger, remembering about something. "Just to let you know before you're too surprised, Yuuto's sister is here to."

They turned their heads towards me with surprised look on their faces. "K-Kiba's sister, the one we talked about last night?" Rias asked. "B-But, I thought she was..."

"She was taken away hours before Yuuto and the others were 'disposed of'" I explained.

Rias let out a sigh of relief and smiled slightly. "I'm happy that he was able to reunite with his sister again, but now we have to worry about why there are Holy Sword users in my territory."

"Let just hope that it just Holy Swords users and not a time stopping gun shooting Yandere." I joked as everyone looked at me weirdly. "I hope not..."

Unbeknownst to us, a girl was scooping her rifle at me as she let out a sigh. "Soon, Cipher-san~" She giggled.

[Timeskip]

The next day after school, everyone had gathered in the Occult Research Club. The atmosphere in the room was dense as Irina, Xenovia and Yuki were sitting in front of Rias, Akeno and me with everyone else sitting behind them. Issei was looking at Yuki with a shocked expression on his face while Kiba was trying to control his anger as he saw the objects that they were carrying.

"Now, let's get to the important stuff." I put down a cup of tea on the table and looked at the Exorcist Trio. "Tell me us the full details about those swords that gone missing."

"Recently the Holy Swords, Excaliburs that were kept by the Catholic Church Headquarter Vatican, Protestant Church, and Eastern Orthodox Church were stolen." Xenovia began as Issei made a confused expression on his face.

"Excalibur itself doesn't exist." Rias answered the question on his mind.

"Well, that the most bullshit thing I ever heard." I commented before looking at the believers. "Can we continue this conversation?"

"Issei, (Y/N)-chan, Excalibur broke in the war a long time ago." Irina explained.

"Well, there's goes the chance of becoming the King of Britain. So, how does this piece look like? It's like piece of puzzle to be attach?"

"To answer your question, this is how the current Excalibur looked like." Xenovia then picked up her sword which was covered in bandages and untied it, once the Devil in the room looked at it, they started shivering including me.

"I remembered that." I pointed out with a nervous laugh. "You tried to kill me with it."

"This is Excalibur. Excalibur was broken into pieces during the war a long time ago. The fragments were collected and turned into a new form by alchemy. It was made into seven swords." She tied the wrapping back around her sword and continued. "The Excalibur I hold is Excalibur Destruction. It's one of the seven Holy Swords that were created. The Catholic Church is in control of it."

Irina then took out a rope that was tied around her shoulder and it started taking shape as a katana. "Mine is Excalibur Mimic. I can change its shape into anything I want so it's really useful for carrying around. Just like this, each Excalibur has its unique ability. This one is in the possession of the Protestant Church."

"Huh, neat." I commented.

Yuki then pulled out a long sword with a unique design. "Mine is Excalibur Blessing. Though it's not an offensive like Iri-Chan's and Xeno-Chan's, it's more of a supportive type. And its increases other based off ones belief and weakens Devil and Vampires."

"Irina, Yuki...There's no reason to tell these devils the ability of Excalibur, is there?" Xenovia looked at both of her partners, currently disagreeing with their explanation.

"Even if they are Devils we still have to form a trustworthy relationship with in this situation. Also, even if my sword's ability revealed, I won't fall behind all the devils here." Irina chirped.

"I felt insulted by that." My left eye twitched in annoyance.

"I feel you." Kokichi slightly growled at Xenovia.

"Ah, sorry (Y/N)-chan." Irina apologized.

"Why are you apologizing to your demon boyfriend?" Xenovia plainly said.

I gulped as I felt an immense dark aura coming out from multiples girls around the room excluding Mittelt, Kalawarner and Pyronica.

Rias pouted a bit before looked at both of them. "So, what does the stolen Excaliburs have to do with this country located in the east of the world?" She interjected them.

"The Catholic Church was in possession of two Excaliburs including mine." Xenovia began. "The Protestant Church also had tow. Also in the Eastern Orthodox Church were two as well. The last one went missing in the previous war between God, Devils and Fallen Angels. One Excalibur was stolen from each Church. The ones that stole them escaped to Japan, brought them to this town."

I narrowed my eyes at the mention of this. 'Wait, why do they only took one sword from each Church though? Why don't they just take all of them?' I thought it for a second.

"What are you thinking about, kid?" Bill asked, getting curious after reading my thought.

"Looks like my territory is full of incidents." Rias said, snapping me from my thought. "So, who are the ones that stole the Excaliburs?"

"The ones that stole them were the Grigori." Xenovia told us, shocking all the ex-Fallen Angels in the room.

"T-That's impossible, Azazel doesn't have any interest in Holy Swords." Raynare said.

"Yeah, the perverted faggot only collect Sacred Gears." Kokichi pointed out, feeling a bit disgusted by the mention of the name. "Unless...that stupid warmonger..."

"Wait, don't tell me-"

"Yes." Xenovia interrupted Raynare mid-speech. "Kokabiel. One of the leaders of the Fallen Angels that survived the previous wars since ancient times...I never expected to hear the name of the one that appears in the Bible." Xenovia then continued her statement. "We sent priests, exorcists, to this town secretly but they kept getting killed." Everyone made a slightly shocked expression on their face after realizing what had happening behind our backs.

"Our request...No. Our order is not to have any devils intrude in the battle between us and the Fallen Angels for the Excaliburs. In other words, we came here to tell you not to interfere with this incident." Xenovia said with a confident tone.

"Such manner of speech." Rias's eyes changed into a serious one. "Is it restraint? Are you thinking that we might collaborate with those Fallen Angels? Perhaps that we might team up with them to do something with Excalibur?"

"Rias, you do realize that my Peerage is consist of Fallen Angels right?" I deadpanned at Rias.

"I'm not talking about you, (Y/N)."

"The headquarters think that it might not be impossible." Both of our expression changed after what Xenovia had blamed on us. "The higher-ups don't trust Devils and Fallen Angels."

"No shit Sherlock." I rolled my eyes.

"We were ordered as if the Holy Swords are taken away from God's side then the devils would also be happy right? The Fallen Angels would also profit from it. For those reasons it won't be weird for them to form an alliance. That's why are we giving you a warning. If you form an alliance with the Fallen Angel Kokabiel then we will eliminate you all. Even if you're the little sister of the Devil King, by our boss."

"I want to see you try, girly." I glared at the bluenette but Issei put his hand on my shoulder, stopping me doing anything non-rational. I took a deep breathe before calming down. "And I thought we bonded, Xeno."

"I never bonded with a Devil." She shot a cold glare at me as Irina give me a concerning look at us.

"...If you know that I am the sister of a Devil King, then it means that you have a lots of connections with the higher-ups in the Church." Rias told her. "Then, I will say it. We will not form an alliance with the Fallen Angels. Never. In the name of the Gremory house. I wll not do something that would tarnish the name of our Devil King."

"My answer is same as Rias." I smirked. "I'm don't do clan with Cockledoo."

Xenovia laughed slightly by what she had responded. "Hearing that is good enough. I had to warn you just in case that Kokabiel is hiding himself in this town along with the three Excaliburs. If something were to happen, I would be the one to be hated by the bunch in the Church headquarters. Well, won't ask for cooperation. If you were to form an alliance with God's side temporally, then it would affect the balance of the Three Factions. Especially if it's the little sister of a Devil King."

Rias softened her expression and sighed. "Where is the person the Orthodox Church dispatched?"

"They have that person put on hold for this case." Xenovia said. "They are planning to protect the last Excalibur if three of us fail."

"So it's just three of you?" I widened my eyes, feeling a bit shocked. "You telling me that you going to retrieve the Excaliburs from the leader of Fallen Angel with just the three of you? That's insane. Are you trying to kill yourself?!"

"Yes." Xenovia responded, nodding her head.

"I have the same view as Irina, but if it's possible, I don't want to die." Yuki told us.

"I really don't want to die, but I don't want to fail my mission." Irina gave me a sad smile.

"Now that some dedication." Bill whistled, slightly impressed by the girls.

"Are you serious?!" I shouted at them.

"You came here to Japan prepared to die?" Rias looked at the three exorcists with a confused expression. "The belief in your teaching is extreme like always."

"Don't talk ill of our beliefs, Rias Gremory." Irina glares at the red-haired girl before turning her head to her friend. "Right, Xenovia?"

"Right." Xenovia agreed with the chestnut-haired girl. "Also the Church decided that it would be better to eliminate all of the Excaliburs rather than letting them get used by the Fallen Angels. Our minimum objective is to get the Excaliburs away from the Fallen Angels. To accomplish that, it's okay for us to die. The only way to fight against the Excaliburs are Excaliburs."

Everyone looked at them in confusion. "Is it possible with only the three of you?" Rias asked her.

"Well, we won't die in vain." Xenovia said.

"Maybe." Xenovia then looked at towards me in secret, leaving me with a confused expression.

'Why she's looking at me?' I thought before deadpanned. 'Don't tell me that she's going to use me?! Not in a million years I'm going  down with them. I still have so much to live as a Devil!'

"Well, suck to be you then." Bill chuckled.

The three female Exorcists then looked at each other before standing back up. "Then we will take our leave now." Xenovia looked at her partners. "Let's go you both."

"So, you won't drink your tea?" Rias asked. "I can prepare a snack for you."

"I don't need it." Xenovia refused her offer with her hand.

"I'm sorry. See you."

"Bye, (Y/N)-chan!" Irina giggled, waving at me.

"Wait a moment." Xenovia suddenly spoke, her attention focused solely on the ORC's resident blonde Bishop. "You...You are Asia Argento the 'Witch', if I'm not mistaken..."

Asia eyes went wide, now trembling with grief over the memory of her banishment. I let out a sigh of slightly frustration, running my hand through my hair.

"Really, that's her?" Irina inquired, looking at the blonde with intrigue. "I would've never thought after your exile you'd become a devil."

Asia ringed her hands nervously. "U-Um...I-I..."

"Uh Iri-chan, Xeno-chan..." Yuki felt a bit uncomfortable at the current situation while trying to get them leave. "I think we should probably go."

Irina's gaze softened. "It's alright. I won't tell the higher-ups I saw you."

"Hm, but to become a devil? Tell me, Asia Argento, do you still believe in God even such a fall?" Xenovia asked curiously.

"Xenovia, just because she's a devil now, doesn't mean she'd have to give up on her faith in the Lord." Yuki reasoned.

"True. There have been people in the past that despite becoming the enemy of God, still hold on to their belief. Is Irina correct in saying you still possess such feelings?"

Asia's gaze lowered to the ground. "Y...Yes," she admitted quietly. "I just couldn't let go of my faith...even now, I still believe..."

Xenovia nodded. "I see, then it would be best if I behead you now in the name of the Lord." At the moment, Xenovia took her Excalibur Destruction and pointed it at Asia. Everyone was surprised when a hand gripped the edge of the blade, black mist starts to come out of it. Everyone looked towards me who was trying my best to ignore the pain.

"There's a lot of things I'm willing to let it slide." I spoke, my voice barely above a whisper with my left eye burst out the red flames. "This ain't one of 'em. Do you have any idea what that poor girl has been through? No. Why would you. In the end, it's all your own benefits. Al the Church ever did was use Asia for their own gain. And, when she was deemed by the masses to be a traitor of God, nobody came to her aid, even after all she had done for them. You all just blindly followed like sheep...bunch of hypocrites..."

For a moment, nobody said anything, the silence was so thick one wouldn't dare to cut through it. Even Bill was shocked before seeing...a small tint of black flames in my left eyes.

"It can't be..." Bill muttered.

"Sheep?" Xenovia hissed. "So is that what you think? Just what is that girl to you, anyway?"

"My family, my friend, do I need to go on for you? I'm not going to just stand here and let you say she should die because it's in the name of the Lord'. I won't let you touch her."

The Exorcist smirked. "Oh, is that a challenge to the Church? Devils do like to run their mouth?"

"I'm not a devil...I'm Dream Demon."

Kiba walked forward, making his presence known. "Well, isn't this perfect timing. Mind if I take her on?"

Xenovia regarded the blonde Knight with a cold stare. "And who are you?"

"I'm your superior." KIba said with a dark smile. "Though I was also a failed creation."

"Brother, don't." Yuki looked at him with a worried expression.

"I'm sorry, Yuki. But the thing I want to destroy is right in front of me and I can't let it go..."

"If that's the case," Issei walked forward as he had a determined face. "Then I have to step in for you brother."

I raised my eyebrows in confusion before nodding my head slowly. "Why though?"

"Hey, Asia is like a little sister to me, so I need to protect her from hypocrites like this." Issei admitted. He then turned his head towards me and grins. "Besides, I know you don't want to fight your girlfriend. Let me do it instead..."

"You just want to do that to make yourself look cool..."

"Am I that a loser to you?"

"...Do I need to answer such an easy question?"

"Fuck you Maid Obsessed Freak."

"Thank you very much, Tits Loving Twat." I sighed in frustration and nodded my head, agreeing with his proposal.

[Timeskip]

Things at the moment went from bad to worse as everyone were standing around outside of the clubroom with a demonic barrier surrounding them. With Kiba and Issei standing in front of Irina and Xenovia.

"Then let's start." Xenovia announced as both of them took off their robes and were now wearing black skin-tight battle uniform, which showed off their body and curves. I was caught looking at Irina with a deep shade of red...until I felt a sharp pain on my left foot.

"Ouch!" I held my left leg and looked to my side to see Koneko slightly pouting at him. "Did you just stomp my leg?"

"...You becoming like your brother..." Koneko said. "...You were eyeing Irina..."

"Man, if she wears a maid outfit, I think blood will shoot out of his nose like a waterfall." Kokichi chuckled.

"You mean like this?" Someone called out as I turned to the side and saw Raynare in a maid outfit. I felt something dripping down from my nose as I move my finger to touch it. I glanced on the skin of my finger and saw a bit of red on it...indicating that I'm having a nosebleed.  "Ah, it works!"

"He yield!" Everyone shouted, completely in shock by my sudden reaction.

"(Y/N)-chan!" Irina pouted in jealousy, snapping me back into reality.

"Wow, I thought your brother were lying about that." Kokichi laughed at my reaction as Mikan wiped the blood on my nose. "Next he will say that he likes catgirls!"

"Yes, this is the first step of losing my virginity to (Y/N)!" Raynare cheered as she looked determined. She then turned around and walked towards me. "Can I serve anything for you, master~?"

"..." I was speechless before nodding my head slightly.

"Ara, guess I need to by myself a maid outfit for myself, am I right Rias?" Akeno smiled, giving out a cold aura as she glares at Raynare.

"Agree." Rias nodded her head in agreement.

"Oh, kid...You're in big trouble." Bill laughed uncontrollably at me.

I ignored all the comments and looked back towards the fight. He looked and noticed that Yuki was looking worriedly towards the match. Both Xenovia and Irina pulled out their Holy Swords.

"It might be interesting to test the strength of Rias Gremory's servants." Xenovia said with a confident tone. "Also, I'm interested in the strength of the so called 'Superior.'"

"Even if it's just a match, be cautious of the Holy Swords!" Rias's warned them.

"Pretend it as if it was a 1000 degree knife cutting through a butter!" I added. "And fyi, you're the butter!"

"Geez, thanks for tip." Issei sarcastically said to me. We then started hearing Kiba laughing to himself as he summoned a Demonic Sword. "..Are you laughing?"

"Yeah." Kiba giving him a dark smile but wasn't as creepy as Kokichi's psychotic one. "The thing I wanted to defeat and destroy appeared right in front of me. I'm happy."

"You're emotionally unstable." I shouted as Kiba gained a tick mark on his forehead. "You're broken inside! Brother Yuuto, I knew you come! Renders the girls as obsolete!"

"Don't encourage him like he was a psycho!" Issei scolded me.

"Hey, he's Jeff the Killer with sword. What do you expect me to do? Give him teddy bear or have sex in the beach?"

"Wha-"

"Ignore the last one."

"I had even heard that by being close to Devil and a Dragon, powers would gather. But for me to encounter this early." Kiba continued to ramble on.

"...Sword Birth, huh." Xenovia said as she eyed the weapon that was in Kiba's hand. "The possessor can create any Demonic Sword they imagine in their head. It's unique among the Demonic Sword related Sacred Gears...I heard that Yuki's supposed twin brother had survived from being disposed by the Holy Sword Project...Is that you?"

"Issei Hyoudou." Irina called out as he turned his head towards her. "When I met the friends that I haven't seen for so long, and they turned into a devil...I was shocked...but I was devastated when (Y/N) turned into one..."

"The past is in the past Irina." I said with a saddened expression. "There's nothing we can do to change it. It's not like someone can go back in time and change the timeline where I'm an Angel and my brother is a Devil."

"Don't thing like that have consequences?" Issei asked.

"They do and I don't want to imagine a world where you fulfilled the dream to become a Harem King."

"Hey! I swear that I'll achieve the dream!"

"Yeah...in your dream only..."

"And what trick has destiny played on us!" Irina continued. "I went to England because I found out that I can use representative of God has given me! Aah, this also must be a trial that God has given me! The land that I haven't been back in for so long! A harsh destiny where both of my childhood friends has turned into a devil! The way time moves is harsh! But by moving forward, I will turn into someone with the true belief towards God! Now Issei! I will give judgment to you with Excalibur! Amen!"

Issei looked at Irina with a confused and dumbfounded expression on her face. "Uh, is there something wrong with your girlfriend?" Irina responded with a blush in her face.

"Nope." I chuckled slightly, gaining a small blush. "She's just holding onto her beliefs."

Issei started trying to figure out what she was saying, but he just shook his head. "I don't actually know what you are on about. But..." He thrust his left arm forward. "Activate Boosted Gear!"

(BOOST!)

Issei summoned his Boosted Gear onto his left arm and pointed it towards her.

"...Longinus?" Xenovia looked at him with a shocked expression on her face.

"Is that Boosted Gear?" Irina asked, also having a shocked expression. "I never thought that I would meet the person possessed by the Welsh Dragon in a far eastern country like this.

"You will hurt yourself if your attention is on Issei only!" Kiba came towards Xenovia with his Demonic Sword and her Holy Sword clashing against each other, causing sparks fly in the air.

"Sacred Gear Sword Rebirth and Boosted Gear." Xenovia smirked. "And also Twilight Healing that Asia Argento has. All of them are Sacred Gear that are said to be a heresy to us. Maybe it was natural for you to turn into a devil."

"My power is also the power made by my comrades' hatred, who were killed while filled with regret! I will beat those with Excalibur with this power, and I will destroy that Excalibur!"

"Here I come, Issei!" Irina came rushing towards Issei slashing at him with her Excalibur Mimic, Issei started dodging all of her slash attacks.

"I'm not done yet!" He said with a confident tone.

(BOOST!)

Power started to flowing throught Issei's body, and Issei started making a perverted expression on his face which slightly terrified Irina.

"...What a lecherous face." Irina said, slightly scared by his expression. "What are you thinking?"

"...Please be careful." Koneko warned. "Issei has the power to blow away the clothes of the woman he touches." Issei faced faulted to the ground.

"Oi, Issei." I looked at him with an angered expression on my face. "I'll mindfuck you with something worst then Shrekening if you use that perverse technique on her!"

"What can be worst that Shrek Is Love, Shrek Is Life?" Kokichi got intrugied as he put his finger on his chin. "The whole Twilight movie?"

"I'm not the cruel..."

"...Enemy of all women. You are the worst." Koneko harshly commented on him.

"Those are harsh words Koneko!" Issei cried out in tears of shame.

"What a lowly technique!" Irina made a sad expression while she started praying. "Aaah God. Please forgive this sinful pervert!"

"I see." Xenovia looked towards Issei with a scornful expression while sighing. "The mass of sexual desire. I think it's a fitting action for a devil that has such strong greed."

"I'm sorry for his behavior." I bowed down.

"I also as well say sorry." Kiba held his hand out and created two more Demonic Swords.

"WHY YOU TAKING ON HER SIDE, BOTH OF YOU?" Issei glared towards us.

"Now back where we were! Burn! And freeze! Flare Brand and Freeze Mist!

"Sound like a Pokémon attack..." I commented with a deadpanned.

One of the Demonic Swords created a whirl of flames and the seconds created a cold air with silver frost, he used his superior speed to charge towards her and attack.

"The Knights swift move." Xenovia commanted. "And flame and ice Demonic Swords. But you are too naïve!" Xenovia slashed her sword downwards and instantly destroyed both of Kiba's Demonic Swords, Kiba made a shocked expression at what happened. "My sword is a mass of destruction. There's nothing it can't destroy."

Xenovia pointed her sword downwards and trust it into the ground, created a powerful shockwave that shook the ground under them. A large cloud of dust started forming around the ground, with Issei and Kiba slightly losing their balance. Everyone including me made a shocked expression by what we had saw.

"So that's the destructive power of one fragment," I observed. "I wonder how powerful the original was."

"Yeah, totally intriguing." A familiar male voice said out loud as we all turned to the said and saw...THE PINES TWINS! "I guess the legend about the Excalibur being broke into 8 pieces is true."

"Gosh, why are you guys fighting?" Mabel tried to sound rational as she her eyes glued on the fight. "Couldn't we all just be friends?"

...

...

...

...

...

...

...

"EEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEH?!" Everyone screamed in shock including the one who was fighting stopped as they looked at two random humans standing around like it was nothing.

"Oh, never mind about us." Dipper waved his arm towards them. "Carry on. I want to study more about your weapons abilities."

"How long you guys been standing here?" Rias asked

"Wha-how-why-whaaaaaaaaaat?!" Kokichi was so shocked that he mumbling like an idiot. "You know about this...supernatural thing?!"

"We been through a lot back at Gravity Falls." Dipper said as he sketched Issei's Boosted Gear in his book with his pen. "Seeing something like this didn't bother us. This just like a regular Monday."

"Of course we knew that you guys are devils." Mabel giggled as she put her hand around Asia's shoulder. "Like, who in the bright idea to think that Occult Research Club is a good camouflage for supernatural beings?"

We all slowly turned our head towards a now embarrassed red haired girl as she was now flushing in dark red like her hair. "Would you guys stop staring at me!" Rias ordered as we all looked back at Mystery Twins.

"How the heck you guys figure in out like...in a couple of days?" I asked.

"First of all, is that..." Dipper pointed at the four people who was still fighting. "Second of all, researches. I've been observing you guys..."

"You mean stalking?"

"Observing."

"You know broseph, we do stalk them all this time. Besides, I had my eyes glued on the blonde beauty..." Mabel sighed as she looked at Kiba.

"I found lots of names in my research that connected to Gremory about Devils." Dipper said. "You should've changed your last name, Rias. Look, I've been researching about this thing for couple of years and all my leads indicates that occult related activity happened in Japan but mostly in Kuoh ranging on Devils, Angels and Fallen Angels. I always do research before going to a place for exciting theory."

"Man, he's good..." Mittelt commented.

"So, my theory are correct. All of you are both Devils and Fallen Angels with the exceptions of the three girls which actually exorcist. But there's only one mystery I never solved just yet." He pointed his pen at me. "You..."

I got a bit nervous as he mentioned me. "W-What?"

"You have a familiar aura that I just can't put my finger too..." Dipper tapped his pen on his chin before shrugging it off. "I think off something later. Now let just enjoy the match."

"BEAT THAT BLUE-HAIRED GIRL, YUUTO! WOOOOO!" Mabel cheered on.

"...I partially apologize for that...." Dipper hanged his head down in shame.

"...I got you..." I patted his back as we both understand the pain of having twins.

"Are you guys actually bonding with each other?!" Bill was flabbergasted as I put my hand finger on my mouth, shutting him up.

"This is my Excalibur." Xenovia began, gaining our attention. "It can destroy anything that comes its way. It's not called Excalibur for nothing."

"...Such a destructive power when it isn't a real Excalibur." Kiba made a shocked expression. "So destroying all 7 swords will be a difficult path."

"Wait, I just remembered...did you say eight frag-" I was about to ask Dipper but he shushed me. "I'll ask later."

(BOOST!)

Issei smirked after hearing the third Boost from his Boosted Gear, while Irina was wiping the dust off of her clothing.

"Geez! I'm all covered in dirt because you destroyed the ground, Xenovia!" She complained. Irina then pointed her sword towards Issei and charged at him. "It's about time to settle this now!" Issei continued dodging Irina's slash attack, she looked at Issei with an impressed expression. "You are doing well! You are good at dodging! Seems like your master trained you well."

"That because that's the only thing he can do." I joked as my brother gained a tick mark on his forehead.

"S-Shut it!" Issei gritted his teeth before smirking at her. "My master is strict with my training! That's why I can even keep up with those stronger than me!"

"Except for me!"

"I said shut it!"

(BOOST!)

"Let's go Boosted Gear!" Issei shouted in determination as his gauntlet shine's bright in green color.

(EXPLOSION!)

"Somewhere in multiverse...A magician girl who obsessed with explosion shivered in excitement..." I muttered slowly.

"What the-" Dipper got uncomfortable with my statement.

Issei released the stored power from his Boosted Gear and it started overflowing from his body, he smirked and started charging towards Irina. "Sorry for stripping you!"

"HE GONNA WHAT?!" Both of Dipper and I shouted with the cap-wearing boy had a shocked expression while I have an angered expression as red flames burst out of my left eye.

"Ewww, gross." Mabel hid behind us at his statement.

"Iri-chan, dodge him!" I commanded.

"Why are you taking her side?!" Issei looked at me, bewildered. Irina avoided his tackle while protecting herself from his perverted actions, Issei regained his posture and continued charging at her. "It's not over yet!"

"...For the lecherous power inside him to increase his stats this much." Dipper deadpanned, thinking whether or not to right it on his journal.

"This is my younger twin brother..." I put my hand on my face both in shame and sorrow.

Issei smirked as he had appeared in front of Irina who made a terrified expression. "What!" Irina shouted in shock. "You caught up with me?"

Irina ducked as Issei went outside of the barrier and jumped towards everyone else, he went towards us who I used wings to fly in the air with Dipper and Mabel, barely dodge the assault. But Issei touched both Asia and Koneko on their shoulder, seconds later their clothing was completely blown away, showing of their body with their face turning bright red in embarrassment. Issei gained a nosebleed along with Dipper and me who wiped it away.

"That's filth! FILTH I SAY!" Mabel pointed at Issei in disgust.

"K-Koneko! M-Mikan! That was an accident." Issei apologized before laughing nervously. "But I think (Y/N) would be happy..."

"Wrong..." Koneko commented as she covered her private area. "...Your brother is furious..."

And with that, I landed on the ground as red flames comes out from my left eye. Dipper and Mabel gasped as they saw my Angry Mode. I slowly made my way towards my now terrified twin brother who knelt down and beg for mercy. Kokichi sends a death glare to my brother as he tried to consult a crying Mikan who was embarrassed.

"Issei...I have some experiments to do..." I creepily smiles. "Have you ever heard of...Boku No Pico?"

"...No...Please no!" Issei cowered in fear before I touched his head. Thirty seconds later...let just say he is curled into a ball with tears running down in his eyes.

"That is the more merciful thing I ever done...Next time, will be a real punishment..." I threaten before eventually calming down from my rage. I snapped my finger, summoning two jacket before covering the poor naked girls. "Here...Sorry about my...stupid bro."

"Thank you...(N/N)..." Koneko blushed a little. I then felt someone hiding behind me, while pressing up their chest against my back. My face turned a shade of red as I turned my head and saw a sniffing Mikan.

"T-T-Thank you...(Y/N)..." Mikan wrapped her hand around me. I felt Kokichi glaring at me before sighing in frustration as he gave his signature childish smile and a thumbs up towards me.

"N-No problem...Koneko, Mikan..." I told them as I looked away towards the fight.

"Issei, are you alright?" In the middle of the fight, Irina was poking a traumatized Issei who was curling in a ball on the ground. "I think that it was divine punishment for creating such a move. With this, you should have learned that you have to seal lecherous techniques like that. Okay?"

"Heed her advice, brother..." I warned. "Or you got into the full Nightmare Inducement...that I even scarred till this day." I shivered as my expression turned into a horrified one...remembering about...Yeah, best we not talk about it now.

"...No...It's the technique I created by putting all of my talents at magic into it..." Issei whimpered. "I'm going to continue blowing away girl clothes...I seriously had a hard time choosing between this move and a move that lets me see through girls' clothes..."

"Didn't you listen what I just say?!" I scolded him, clenching my fist in anger.

"I'll take the risk..." Issei started to slowly get back up from the ground. "I'm going to continue fighting until I blow away girls clothes just by looking at them!" Issei went back charging at Irina with a determined expression on his face. "Irina Shidou and my twin bro! Sexual desires are a source of power! It's justice!"

"I still can't believe he can stand even I mindfuck him..." I sighed in frustration, running my hand through my hair.

"Even though his a pervert, he is persistent." Dipper nervously chuckled.

"More like full of hormones and sweats." Mabel commented as Kokichi and me burst out of laughter.

"Amen! God, lend me the strength to cut down this lecherous devil!" Irina gripped her Holy Sword and came rushing towards Issei, he lowered himself so he could kick her. She noticed this and did a small jump, Issei looked towards her and tried for an uppercut. Issei missed her, she made sharp eyes and swung her katana to the side. Issei dodged the attack by jumping backwards "...I'm sorry. Looks like I was taking you a bit lightly. You have a good movements."

Issei eyes widened as he looked down noticing that he had small cut with smoke coming from the wound. I sighed before rushing forward as my twin fell to the ground as with his Boosted Gear reset and losing the power he had gained.

"I'm guessing that's the damage caused by the Holy Sword?" Dipper asked.

"Yes." Rias nodded her head. "If it were a bit deeper, then it would have been critical."

"You're an idiot..." I sighed with Asia making her way towards my brother and starts healing him. "By the way, are you mentally alright?"

"No...Still scarred..." Issei admitted. "Try to think of boobs but mindfuck really ruined it for me...DAMN TRAP!"

"That's what happen if you tried to lewd Asia and Koneko even if it was an accident."

"Haaaaa!" We all turned our attention back to Kiba as he charged at Xenovia by creating a large Demonic Sword in his hand. "The destructive power of that Holy Sword or the destructive power of my Demonic Sword! We will see which one is stronger!"

"It's a shame." Xenovia sighed in disappointment. "You made a wrong decision."

"I thought she was going to say 'You are already dead'." Kokichi commented.

"Me too." I nodded my head slowly.

Xenovia slashed her sword upwards and completely destroyed Kiba's Demonic Sword. "Your weapon is the variety of the sword you can create and your speed. You would need a lot of strength to swing a gigantic sword like that, and you will lose the speed that you are proud of. Are you seeking a destructive power? From your fighting style, it's something unnecessary. Don't you even know that?"

Xenovia then hit Kiba in the stomach with the pommel of her Excalibur Destruction. Kiba fell to the ground after spitting up vile. "Even if it's not a hit with the blade, that hit just now will be enough to stop you from standing for a while." Xenovia turned around and started walking away.

"...Wa-wait!" Kiba tried getting back up until he felt someone placing their hand on his hand. He turned his head and saw Yuki looking at him with sad eyes.

"Brother, please just stop." She pleaded him. Kiba could only looked away and clicked his tongue, as the barrier was released.

"Senpai, I suggest you fight with coolness the next time we fight." Xenovia told the Knight of Gremory as she sheathed her sword. "Rias Gremory, I trust you with the talk from earlier. This goes to you as well, (Y/N) Hyoudou."

"Yeah, yeah." I lazily waved my hand, striking her nerves a bit more. "Anything else, Blue-Haired Heretic?"

"DON'T CALL ME THAT!" She scolded me before clearing her throat. "Also, you should train your servants a bit more. There's a limit for polishing their battling style." She then looked at Issei. "If you remain the way you are then the Vanishing Dragon will be the one who comes out victorious."

"Vanishing-what?" Both of Dipper and I raised our eyebrows in confusion as Xenovia picked up her belongings and started walking away.

"Wait for me Xenovia!" Irina followed her from behind as she turned around and waved at us. "Tell e whenever you want to get judged, Issei. Amen."

"Don't worry, Iri-chan!" I waved back. "I got it covered!"

"Really bro?!" Issei glared at me. "Why are you siding her than your own twin brother?"

"Because I can."

"Please be careful, brother." Yuki hugged Kiba tightly before walking away from him. Kiba looked towards the ground with his fist clenched.

"Is there something wrong with the way Kiba's acting towards the Excalibur?" Mabel asked, slightly concerned about the blonde haired boy.

"...It's quite personal." I told them. "So, you guys going to shut your mouth about this thing?"

The twins looked at each other before nodding their head. "Well, this have been a...fun experience." Dipper chuckled a bit.

"Oh please...this is just the glimpse of our supernatural world." Kokichi rolled his eyes.

"Well, be off then." Dipper said as he closed his books and walked away with Mabel.

'Well, it seems we've just got involved in this mess.' I thought, looking at Bill who was silently glaring at the twins before looking at him. 'But...did Dipper just said that there's eighth Excalibur?'

"Looks like we going in for some Excalibur Hunting." Bill crossed his hand.

Third Person's POV

Dipper and Mabel made their way out of the school before looking at each other. "Mabel...you felt that right?"

"Yeah...(Y/N)'s aura felt..familiar." Mabel shivered slightly. "It couldn't be him...right?"

"We can't be so sure. All we know is they are a Devil and they're involves with the missing Excaliburs. And mostly, I already theorize that the eight one is somewhere around here."

"Shall we tell Grunkle Ford?"

Dipper pulled out his phone from his pocket and dials some numbers in it before putting it on his ears. He waited for a couple of minutes until he heard someone answered the call. "Hello, Great Uncle Ford...your prediction might be right..." He looked at a page with Bill Cipher on it and the riddles that was given by Axolotl. "He is back..."
