(Y/N)'s POV

...He's dead... Kill him...He's dead... Kill him...Cipher's dead...Kill Bill...Cipher's dead... Kill Bill... Cipher's dead... Kill Bill... CIPHER'S DEAD... KILL BILL... KILL BILL... KILL BILL!

I heard the words echoing in my head, I'm currently in a dark place. I look around the area with sweat dripping down my body. My eyes went wide when I saw a boy with brunette hair lying on the ground with blood pouring from his abdomen.

"I-I-Issei bro..." I said with fear in my voice. I heard someone laughing maniacally behind me, as I turned around I saw all my friends laying motionless on the ground. I took a step back with my body shaking, I slowly looked down and lifted my hands... Blood... Someone's blood is on them... This couldn't be their's right?

It's your fault... It's your fault... IT'S YOUR FAULT!

"N-No... This can't be true..." Tears started to run down my face, my body kept shivering from fear. I covered my ears with my hands while the voice kept blaming me for their death's while the laughter kept echoing. "S-SHUT UP! I SAID SHUT UP!"

Your fault... Your fault... You killed them... You killed Bill... YOU KILLED BILL!

I looked down and saw Bill's head on my leg. I screamed in fear before falling on my ass, sliding away from the decapitated head.

"No... No... This is... NO!"

Bill's eyes opened revealing a blue light as he glares at me. "Always...watching..."

Always watching... Always watching... Always watching...

"STOP! I SAID STOP!" I begged, closing my eyes from the horrifying image, my heart was beating quickly from the shock. I should've run but I can't, I don't know why but I can't stand nor do anything. "Please... Stop..."

"My god, you're pathetic..." A voice called out. I reopened my eyes and saw everything turn dark once more, I felt someone holding my shoulder forcing me to stand. Looking into a brand new face that I never saw before. "You couldn't even last a couple minutes of my mindfuck. You call yourself a Dream Demon? You're nothing but a wuss, lad." He said with some disinterest in his eyes, before someone pushed him away.

"WHAT IN THE WORLD ARE YOU DOING HERE, SANDMAN?!" Bill shouted, still breathing and in his human form. "You broke the ground rules! What did I tell you about invading my host's mind?"

"My fingers were crossed." The man admitted, snapping his fingers to summon a cigarette from thin air before lighting it with Bill's fire.

"Hey, this is a no smoking area!"

"Fuck the rules."

"What the fuck is happening right now?" I shouted out loud, gaining their attention. Yes, I'm scared, confused, and tired beyond hell of what I just saw.

"Yeah, what the fuck are you doing here anyway, Sandman?" Bill glared at the man who he called Sandman.

"I'm here to warn the kid about something." He replied, puffing out smoke from his cigarette with half-lidded eyes. "But I got tired of waiting for him and decided to play some mind game's with him..."

"Playing? The kid almost went insane because of your 'Game'!" Bill scolded the man while putting both his hands on his hips. This is weird... it's like seeing a married couple have an argument with me as their child. "You sir, better leave the premises or you'll have to feel my nightmare! You got that?"

"Your nightmare's are child's play compared to mine, Dorito."

"Are we really having that kind of conversation?"

"Yup."

"Castiel... I knew you since the beginning of time... But you are billion's of years younger than me... So fuck off!"

"That doesn't concern me. You are vulnerable in dreams and I can forcefully trap you in my mind just for fun." The man named Castiel merely replied, still with a disinterested look on his face.

"Please don't remind me of all the time we wasted playing Monopoly in your mind..."

"Do you guys want me to... I don't know... Leave you guys alone?" I nervously chuckle as both of them stare at me.

"Yeah, I've been here for far too long by fucking his mind." Sandman threw the cigarette away and it hit's Bill's tuxedo, striking the Dream Demon's nerves, red flames burst from his left eye. "Kid, I want to warn you about something... He's coming."

"Who's coming?" I asked with a raised eyebrow.

"You'll see. Now... Wake up." He snapped his fingers before I fell down into the darkness below.

"FUCK YOOOOOOOOOOOOOOOOOOOOOOOOOOOO-"

[Reality]

I shot up from the bed, panting heavily as sweat drips from my shirtless body. I looked to my side and saw a beautiful girl with long, red hair, a voluptuous body, and well-endowed breasts. She slowly opened her eyes, showing off her bright blue eyes and gave me a concerned look.

"(Y/N), are you alright?" She asked, putting her hand on my chest.

"Nothing Rias... It's just... a nightmare..." I then felt the backside of my shoulder hurt like it was being burned by something. I winced in pain before shrugging it off.

"(Y/N)!" She sat beside me and looked at my back before letting out a gasp. "Your mark... It's glowing..."

"Strange..." I panted a bit. "Haven't felt that in a long time..."

"(Y/N)! Buchou! Are you up already?" A familiar voice knocked on my door as I perked up.

"Yeah, we're up..." I shouted.

"And also, can you give me a detailed story of your amazing night with her?" I heard him snicker a bit behind the door.

"Fuck off Issei! You Breast Obsessed Freak!"

"Whatever, Maid Obsessed Freak!

"I don't have a maid fetish!"

"Oh really?" Rias smirked as she lay her head on my left shoulder. "You're into maid outfits?"

"N-No! My brother is just being his delusional, perverted self..." I stuttered a bit with a small blush on my face. I looked at Rias who was giving me a mischievous smile. "I'm telling the truth here! Don't give me that 'Are-you-sure?' look."

She giggled in amusement and kissed me on my cheek before getting off the bed. She looked at me and said. "We need to be quick or we are gonna be late for school."

"Yeah, I know..." I gave a small laugh.

"Also, wear a scarf to hide that bite mark I gave you last night."

I jumped in shock before quickly getting out of the bed and looked in the mirror. And yes, there is a small love mark on my neck, as he touched it he screamed. "Not again!" in despair, lowering his head.

Why do I always have to deal with this kind of mornings?

[Timeskip]

"NOT AGAIN!" Both Motohama and Matsuda shout in despair as they saw me sitting on my chair in my school uniform with a scarf around my neck. My eye twitched in annoyance, thinking that I may have to head slam on my own desk.

"Oh my, who is the lucky girl this time?" Aika chirped as she made her way towards my desk.

"I bet its Rias... He probably played with those big, juicy melons by himself!" Motohama accused.

'Well he's not wrong about that...' I gave a nervous laugh.

"Or maybe it's her sister, Gremory-sensei! He must've run his hands over her delicate body!" Matsuda gritted his teeth in jealousy as tears run down his face. "Or he might have scored them both at once! Why does he have to be so lucky with woman!"

"This is unfair! Fucking unfair!" Motohama screamed as he hugged Baldy and they both cried in despair.

'Why do I have to deal with this stupidity this early in the morning?...' I cried in shame. 'Even mom and dad decided to make it worse by bragging about it during breakfast like it was a normal thing to do!... When did my life become so complicated...'

"What? Are they talking about Asia?" Pyronica and Mikan walked towards us, interested in our conversation. And yes, for some reason Mikan managed to get Sona to change her Mikan's class to mine. I don't know why she was willing to do that.

Asia tensed up as she blushed madly before fainting on the spot. As a highly working sociopath, I deducted that she peeked during my... "Business" with Rias that night. "Cheeky girl..." I muttered slowly.

"Asia!" Mikan shouted in concern as she ran forward before accidentally slipping and falling into another embarrassing position while the Perverted Trio looked down in happiness. I finally snapped and slammed my head on the desk... Really hard.

From a couple desks away, Raynare in her human form whimpered with tears of despair in her eyes. "Not again... My chance with Master is slowly slipping away... If this continues, Master will definitely abandon me and throw me away like a rotten sack of potatoes..." She cried out as Aika sighed and tapped her back.

"Be strong Yuuma." She encouraged the Fallen Angel in disguise. "One day, you'll get your hand into his pants. They probably won this round but you'll win the war!"

Raynare nodded as she quickly stood up and thrust her hand up in the air, showing determination on her face. "Yes! One day, I will have sex with Y/N!"

"DON'T SHOUT IT OUT LOUD LIKE THAT, YOU IDIOT!" I scolded he with a comical look on my face.

"Ah~ Master scolded me! This is one step closer to achieving my dream!"

"You're killing me here!"

"He...Hehe...Hehehehe..." I heard a very creepy laugh, that sent shivers down my spine, coming from behind me. I turned around slowly as it was rather shocking to see Mikan laughing slowly before pulling out multiple sharp medical tools, tilting her head to the side in a cute manner. I would've cooed if it wasn't for the fact that she gave me a death glare under that cute smile. "(Y/N)...let's go practice medicine~"

"Oh fuck no!" I quickly ran away with Mikan chasing me with syringes in her hands. "Have mercy on me!"

"Don't worry Y/n, it's not going to hurt~ trust me~!"

"Not with those things in your hands! NEIN! NEIN! NEIN!"

"Her personality completely did a 180..." Pyronica nervously chuckled before blushing a bit. "Do it with... Cipher..."

At the back of the classroom, Bill was laughing at me with tears of amusement in his eyes. "Man, this is gold! This is even better than last time!"

"Well, I guess I have to do this then..." I turned around and bravely faced the now Yandere-ish girl, I quickly grab her by her shoulders. "Mikan, look at me!" She glanced at my face before I leaned in and quickly kiss her on the cheek. She immediately fell onto the floor blushing madly and squirming over the fact I just planted my lips on her face.

"(Y-Y-Y-Y/N) K-K-Kissed me?1" She stuttered. I think I can see smoke coming from her head, while I try to ignore Aika's mischievous laugh.

"I can't believe you're that bold!" She keeps on laughing at me.

"It was your fault to begin with!" I scolded her, clenching my fist in anger. I then blush a bit as I looked away from them. "I can't believe I did that in the class- dodge!" And thus, I proceeded to do so as Matsuda, going in for a punch, hit Issei's face instead.

This is getting more annoying every single minute... I swear that I would rather be mindfucked by that man last night... Who the fuck was he?

[Timeskip]

"YOU DID WHAT?!" Sona screamed into my ear as she dropped a pile of paper onto Saji's foot. The blonde boy quickly screeched in pain as he began to jump around while holding his foot.

"Wow, can you scream a little louder into my ear?" I rubbed my ear, sitting on a couch with Tsubaki giggling at me. "And I'm still rocking this scarf. Thank you very much, Ms. Vice President."

"I don't think you should worry about me..." She pointed at her President who is... Let's just say furious, at the fact I took her best friends V-Card. She surprisingly grabbed my collar and shook me back and forth so fast I could puke at any moment.

"Why would you do that? Why would you do that? I'm not jealous! You're jealous!" She rambled on before I took her hands off my collar.

"Sona," I said with a serious tone. "Calm down, okay? I'm still with you, aren't I? Maybe one day... We might do the same thing... Man, I sound just like my brother... Crude..."

She looked a bit reluctant before glaring at me again and slapping my face. She puffed her cheeks a bit. "Whatever hub-" She tensed up before a blush appeared on her face before she turned away to hide it. "Forget it... It's not like 'He' is going to care anyway..."

"What?"

"Nothing..."

Saji walked towards me and leaned towards my ear. "You're one lucky motherfucker. I can't believe you date Sona and had sex with Rias Gremory on top of that."

"If you want to know, she's my second one." I turned around and looked at the clerk. "My first was actually with Koneko."

"No way! I can't believe the FBI didn't catch you-"

"Finish that sentence and I'll do something even worse than the Shrekening." I glared at the blonde-haired boy as he immediately shut his mouth.

We then heard someone knocking on the door. We turn towards the doorway as Tsubaki opened that door, revealing a new face as he walked into the room he scanned around before his eyes landed on me.

I got a bit tense when he stare at me with those cold piercing hazel eyes before looking at Sona with similar demeanor. "I'm here for the schedules." He said with a serious tone or more of 'Don't Fuck with Me' manner.

"I see... You're the new kid." Sona said, completely unfazed by his cold stare. Tsubaki walked towards him with a piece of paper containing the school's schedule. "Quite odd for a Third year coming this late to school."

"Actually, I don't care... He turned to walk out before looking back at me. "What's your name, kid?"

"Huh?" I got startled a bit before clearing my throat. "(Y/N) Hyoudou... Whats yours?"

"...Tyrion Foster..." He then walked out of the room, the cold silent aura in the room dissipated, we all let out a sigh of relief.

"Who was that guy?" Saji asked while wiping sweat from his forehead.

"No idea... But we might see him again sometime..." I said as Sona nodded. "Why do I get the feeling he's gonna get himself into more trouble than me?"

"No clue... I'm actually quite worried about it." Sona admitted as she looked at me.

"Well, if there's nothing more... I'm going to class." I give a quick peck on her lips, making her blush as red as Rias's hair before cheerfully walking out of the room. "Adieu~!"

"(Y/N)!"

"To be honest... I'm jealous of that man..." Saji sighed in defeat before nervously chuckling. "But he looked so cool."

[Timeskip]

I walked home alone from a job someone requested me for. 'Man, that job was hard... Asking me to pick a waifu in Persona 5? How the hell was I supposed to do that? All of them are beautiful!' I yawned a bit. 'Unfortunately, we can't go out with Sae though. Stupid game...'

"What are you even thinking right now, kid?" Bill came out of nowhere startling me for a second before he started to walk beside me. "What? Never saw a demonic triangle man before?

"That's a stupid remark." I truthfully told him as we both kept walking. "Bill, who the fuck is Sandman? He's not your gay husband right?"

"We're not in some sort of relationship!" He scolded me as flames burst from his left eye.

"Really? The fact that you two argue like a married couple says otherwise."

"Dammit. I knew that man will destroy my credibility as a Dream Demon."

"So, my question still stands." I looked at him with narrowed eyes, showing that I'm serious about this matter. "Who is Sandman."

"Cass... He's the same as me." He answered, calming me down from his short rage.

"A flying demonic triangle that looks oddly like a Dorito?" I blankly reply with a stoic impression on my face.

"Not that kind you idiot." Bill deadpanned. "He's a Dream Angel."

"Kind of stupid. Let me guess, he's the opposite side of you? The Yin to your Yang?"

"Yup."

"I was being sarcastic."

"And I never took it as one."

"Well, so you're telling me that he's equally as powerful as you are?" I raised my eyebrow at him.

"Not as powerful. Just slightly less... He doesn't have the rest of our power be he does have Nightmare Inducement, forcing himself into someone's dream at will and trapping people in his own Dreamscape."

"So, him trapping you is the real deal? Wow, I never thought someone could be that dangerous with that power. So he controls people to help them sleep? Cause he is THE Sandman?" I asked the one-eyed demon.

"That was his original job... Until he fell from Heaven." Cipher told me, making me tense up.

"He what?"

"Well, that's some personal stuff, I'm not gonna tell it."

"Well... There's a lot of stuff happening now. Some part of me is telling me things are about to get weirder now,"

"You got that right." Bill laughed at me as I only give a small smile as we walked towards my house. "Hey kid, about that nightmare you had... Is that your deepest fear? Losing a friend?"

Silence occurs between us as I felt a bit downed, remembering the nightmare I had last night. Even if it was just Castiel's mindgame, he still managed to depict the deepest fear I hid for a long time. Losing a friend...

"Look kid, I can read your mind." Bill said as he put his hand on my shoulder. "Kid, you have to be responsible now. Unlike me, I don't have any creed on doing anything but destroying the world and having fun before I got trapped in your body. Now my responsibility is teaching you how to be as much an asshole you can be with my power."

"Yeah, I've slowly started to become like you, even as we speak." I gave a light laugh.

"While your responsibility is taking care of people around you. You have the heart and you have the strength to do so. But remember, you're not alone. We're here to help you out with everything we can.

I looked at Bill who was giving me a brotherly smile. That's really unusual for him to do so, I then nodded as I felt a little more determined. "Alright, I now know that I can protect my friends!" I cried out with a grin on my face.

"Sounds clichè but go get 'em! Power of friendship, screw that. We got the power of bullshittery!"

"WOOOO! YES! BULLSHIT POWER!"

"What the fuck are you actually doing?" I heard Issei say as he opened the door to my house. Huh, I never thought we would arrive at my house already. "Why are you screaming about 'bullshit'?"

"Shut up, lizard hand!" I pushed him away while giving a smug smile. "With the Power of Bullshittery, nothing can stop me! Not even you!

"Okay, you're being delusional now. You're saying that you can beat me?" Issei got a bit irritated by me as a tick mark appeared on his forehead.

"Absolutely! I can beat the snot out of you with my intelligence!"

"Well, Brawn can beat Brains anytime when you get cocky, bitch!" Issei shouted as we both slammed our heads together in anger, trying to out power the other by using our heads.

"Oh please, you have the same amount of strength as a toddler! You Oppai obsessed freak!" 

"Shut up! You can never understand the beauty of boobs. you Maid obsessed freak!"

"Oh, like you'll understand the beauty of-" I stopped mid-sentence as I realized I was about to confess my dirty little secret.

"HAH! I KNEW IT! You do have a maid fetish!

"Is that true, N/n-kun?" Asia asked as she was standing near the hall, looking at us with a reddened face.

"It's true Asia. We might need to wear a maid outfit to gain Y/n's attention more often~" Rias giggled in amusement.

"My, I never knew you were such a naughty boy!" Bill laughed at me as he walked away, pulling a journal out of his pocket.

And that was when I snapped. I swung my fist right into Issei's face. My younger twin looked in shock before punching me in the face... REALLY FUCKING HARD. We both stared at each other for a couple of seconds, registering what just happened.

"OKAY, THAT DOES IT!" We both shout as we start to brawl in the hallway... Okay, more like childish slapping and punching.

"Now that is just pathetic..." Bill commented before writing in his book and walking away from our fight.

"Boys..." Rias glared at us, giving out a menacing red aura as we both hug it out like a pussy. "What did I say about fighting each other?"

"This isn't a fight, it's just... brotherly bonding! Yeah, that's it!" I nervously laugh while caressing my brother's hair. "Right, Issei bro?"

"Aye!" Issei replied nervously with the same comical smile as me. Rias gave one last glare before walking away from us, followed by Asia. We both waited for a couple of minutes in the most awkward bro hug we ever did. "Are they gone?" Issei whispered to me.

"I think so." I replied back.

"Good!" My twin chirped happily... Before viciously headbutting me as we both got into a brotherly brawl once more... Until Rias came back with a anger rivaling an angered lion. Let's just say, that night I had to sleep on my stomach with my butt in the air... Ouch...

Third Person's POV

Somewhere in the dark, a stray devil was running away from something as a couple of figures jumped down from the shadows. As they fell the stray hit a dead end, he panted heavily as his face was filled with fear. A noise behind him caused him to turn around, he pulled out a small dagger and pointed it at his assailant with a shaky hand.

"Stay back!" The stray warned as one of the men slowly walked forward with a big sword in his hand. "You're gonna regret what you did to my brother!"

"Shut it, devil." A male voice called out as he pointed his sword at him. "The sins that you have committed towards those innocent people, those that you have killed. It's despicable and you deserve to be punished."

"Lets beat this rubbish demon into submission." Another male voice called out in a very calm demeanor.

"Can I just shoot him in the head? Like seriously now?" Another voice said slight annoyed, but this time it was a female voice. "This devil is nothing but a joke!"

"But the bounty on his head and his brother is quite big!" The man with the big sword whined. "I need the money... For reasons."

"LAST TIME, YOU USED IT ON YOUR STUPID GAMBLING ADDICTION!"

"It's not an addiction, it's a hobby!"

"They're going at it again..." Another male sighed in frustration. "At first it was funny but later on, it just got stale and annoying."

The Stray was about to make a move as he lunged forward to a defenseless girl but a hand suddenly appeared and grabbed his neck, slamming him to the ground. The devil let out a gasp as he tried to claw his way out of the hand on his neck, losing some of his precious oxygen in the process.

"I'm usually a pacifist, but trying to attack one of my friend's is just plain rude." Another male's voice called out as he held the Stray's neck tightly before his left hand covered itself in stone. "And for that, you deserve to be slain. Any last words, Stray?"

"M-Mercy! Please don't kill me!" The Stray struggled to say those words as the man looked at him with cold eyes.

"I bid thee farewell." And with that, he raised his stone-covered hand and slammed it into the devil's face, splattering his head into pieces. The man stood up, dissembling the stone gauntlet on his hand before crying out in despair after looking down at his now dirty shirt. "You got blood on my favorite shirt!"

"Really? That's your complaint about that thing?" The impatient man in the shadows said as his eye twitched.

"YES! Now I can collect the bounty!" The boy with the big sword cheered before getting hit in the head with a bow. "Ouch, what was that for?"

"You're not going to use all of our savings on gambling!" The only girl in the group said.

"That's not the point of our visits in Kuoh." The calm man said. "Any sign of Kurumi yet?"

"Nope... But we need to find her. She's our group member after all..." The leader said as he walked out of the shadows to reveal a man with white hair and red highlights in his hair.

" The leader said as he walked out of the shadows to reveal a man with white hair and red highlights in his hair.

(He have red and white hair yet one black streak on his head - Ps. Thanks SwordAir)

"Really though, why are we chasing her anyway?" The impatient man scoffed as he twirled a spear in his hand. "She's been nothing but a nuisance. And since the day when we scouted for Cipher's host, she had gone gaga on him and decided to stalk him... Like forever. Why don't we just leave her where she is and return back home to Ireland?

"You just want to go there to bang girls..." The leader deadpanned.

"I do not!"

"You're just as bad as him..." The girl sighed in defeat as she talked about the gambling loving boy who was taking a picture of the dead devil with his phone.

"And send!" The boy smiled before looking at the girl who got irritated by that. "What?"

The boy with mixed-colored hair sighed in frustration before looking towards the dark skies. "Cipher... I'm coming for you..."

Opening 2 (Song: Tank!)

[0:01 - 0:03] A couple seconds in, a glimpse of a picture of Y/n, Rias, and Issei was shown with Y/n smiling towards the camera, Rias looking sideways with the wind blowing in her hair, and Issei had a shocked expression.

[0:04 - 0:14] (Y/N) can be seen up near a balcony with a flask in his hand with Issei beside him, oogling on some woman who passed by them. (Y/N) sighed at the flask. 'Okay, three, two one' (Y/N) quickly dropped the flask and turned around followed by Issei and mouthed 'Let's jam!'

[0:15 - 0:21] (Y/N) can be seen running with Bill floating behind him with journals in his hands. They stopped mid-sprint and turned around with flames in their hand and their eyes burst out blue flames.

[0:22 - 0:28] Rias can be seen walking towards the Occult Research Club room followed by Akeno. They both quickly turned around and grabbed (Y/N) sending glares at each other as they play tug-o-war with Y/n as the rope.

[0:29 - 0:33] A shot of the characters. It starts with Koneko with her usual stoic expression, followed by Kiba with a doubtful expression, Blair with a seductive wink, Kokichi with a sinister grin, Asia with her cute smile, and a blushing Raynare who was caught off guard from the camera flash. It then changed to Y/n giving a roundhouse kick in slow motion.

[0:34 - 0:45] A glimpse of a picture of two new girls, Xenovia Quarta, Irina Shidou and blonde girl, respectively before showing off a girl with mismatch eyes giving a Yandere-ish glance towards a now scared Y/n. It then shows Kiba walking slowly, distancing himself from the Peerage until the Hyoudou Twins grab both of Kiba's shoulders and pull him back in with a smirk of their own.

[0:46 - 0:48] It shows Bill and Y/n in different direction's pass through each other. The brown-haired boy realized and turned around to see Bill was looking staticky like a television.

[0:49 - 0:56] It then shows Castiel smoking in a bar with a single beer on his table before he stood up and left. He then quickly turned around and aimed a shotgun at a TV screen, he pressed the trigger, revealing Bill Cipher's mark behind the broken glass.

[0:57 - 1:02] The camera panned out showing Ria's Gremory's current Peerage in an elegant white outfit ranging from dresses to tuxedo's while each of them holds something in their hand. Whether it's a phone, purse, or a glass of water. It then changed to Y/n Hyoudou's Peerage with them wearing the opposite color of the previous clan, while they held guns like a group of from the mafia.

[1:03 - 1:09] The first shot was of Issei jumping around before the background changed to show his Ddraig. It then changed to Rias dancing seductively, aiming a magic circle while the background showed a picture of Sirzechs Lucifer, it then changed to Kiba who swiftly swung his sword before the background showed Excalibur behind him. The last is of Y/n walking by the camera and stopped in the middle of the screen, looking forward in confusion while Bill in his original form appeared behind him.

[1:10 - 1:19] It then showed a group covered in shadows with only the leader standing in the light giving a friendly smile, before getting a bit serious as a giant shadow of a man with 10 wings appeared. Then there's a shot where both Y/n and the silhouette were fighting each other while Freed clashed blades with Kiba before getting interrupted by a guy with black hair and a fox mask covering his face. Then it showed multiple scenes of the group showing off their skills.

[1:20 - 1:23] A picture of Cipher's and Rias's Peerage in a Wanted paper on the wall was shown before it was burnt to a crisp by blue flames. The screen goes black showing the title card [1:24 - 1:31]

DeCipher Dreams! (Bill Cipher Male Reader x Highschool DxD)

Then it showed a glimpse of the back of a boy with a blue cap and a girl with long brown hair wearing a sweater before the screen turned black, like an eye closing.
