(Y/N)'s POV

After all the morning stuff happens, we both decided to forget about it and continue to go school like usual with Issei sent me ahead of him so I could meet up with Matsuda and Motohama revealing whatever fantastic about this girl that he want to show us. Finding those two pervert wasn't difficult; they always waited just outside the school for us.

"Hey, (Y/N)," Matsuda greeted me which I replied with a simple wave. "Where's Issei at?"

"Getting some big surprise ready, apparently," I casually said before yawned loudly. "I don't care what it is. I just want to get some snooze before the bells ring."

"Intriguing," Motohama pushing up his glasses. "I wonder what it could be?"

"A walking body pillow perhaps?"

"That's very genius (Y/N)!"

"I'm being sarcastic, four-eyes."

It wasn't long before they both found out as I leaned my head a bit to see it. 'Wow, he really does had a girlfriend. I'm impress yet jealous.'

"Oh please God no!" Matsuda cried, figuring out exactly what was happening.

"Wha?!" Motohama said in a baffled state.

Issei and the girl arrived at the front school. The girl wore a polite smile and looked a little shy, which I really think was absurd, considering just how attractive she was. Meh, don't judge the book by its cover they say.

"Hey, guys, (Y/N)." Issei said coolly. "This is Yuuma Amano, my girlfriend." He said it casually like he thought he had always been confident getting one. "These are my good buds, Matsuda and Motohama. And this is my less attractive twin brother, (Y/N)."

"You cheeky, Issei." I muttered under my breath, didn't want Yuuma to hear me.

"It's nice to meet you," Yuuma bowing politely. Her voice was sweet on the ears.

"And here's the best part, dudes." Issei spokes his next words in a whisper with a giant grin on his face. "She...asked...me."

Matsuda and Motohama's mouth were open wide with shock as they were speechless. I'm on the other hand just had a small smile on my face, genuinely happy for my twin brother. I just held my fist at him which we bumped each other.

Issei looked at Matsuda and Motohama, grinning even more widely. "Hey, stop whackin' it and you'll find one too," He said to them. "Let's go, Yuuma."

Yuuma gave us one last bow before she and Issei walked off together. 'I don't know why...she look perfect...to perfect for me...'

"Traitor!" Both of Matsuda and Motohama decided to proclaim my brother as that. I just sighed before patting their back and walked away.

'If even someone like Issei can get a girlfriend, then I shouldn't have a problem...I still feel suspicious about that girl...' I thought, making my way towards my classroom. On the way there, I bumped with Koneko at hallway, smiling at her. 'Maybe...just maybe I'll try ask her out.'

"Hi," I greeted her cheerfully.

"Hello," She said in her monotone voice.

"So, how're you doing?"

"I'm doing well. How about you?"

"I'm good..." I suddenly felt very nervous. I brethed deeply in an attempt to get control of my heartbeat and nerves. "Hey," I said getting her attention. She looked at him and I felt my nerves slip. "Do you wanna...I mean, would you like to...If you wanted, we could..." Well, there's goes all my confident I had a moment ago left me rather swiftly into the drain. "Y'know what? Never mind." I quickly waved her off.

"...Are you alright?" Koneko asked me. I might have imagined it, but I think I heard a genuine concern in her voice.

My face went red as I looked away from her. "I'm fine," I unconvincingly replied. "Just...forget I said anything, I'm bring stupid."

"I don't think you're stupid."

"Well, see you after school."

"Same spot?"

"Yeah..." And we that, we end the embarrassing conversation 'I'm fucking pathetic.'

[Timeskip]

I was doing some research about the sign on my shoulder but to no avail, not a single traces of it appears on the screen. Come on! It's the bloody internet, for fuck sake! I looked at the clock and realized that Issei got home late again. I was indeed happy that my brother have a relationship but at the same time I'm fucking jealous about it. I was a confident guy, and people at the school actually liked me, yet my brother, who had never done anything but repulse the girls of the school, had managed to get an incredibly beautiful girlfriend with little to no effort at all. Meanwhile, I was struggling to ask a girl I had grown to know for quite a while at Kuoh Academy.

'You lucky son of a gun,' I thought to myself while staring at the reflection of myself on the mirror. The amount of depression had set in after my failure to ask Koneko out on a date earlier in the day.

I heard a knock at my door as I looked at it with a lazy eyes. "Not locked,"

"(Y/N)," Issei opened up the door as he smiles. "Can you do me a favor?"

"Depends on what it is," I twirled my pen on my hand, looking at him with a slight interest.

"I've got a date with Yuuma on Sunday, and I don't wanna mess it up. So...do you think you might able to keep an eye on us and make sure I don't do anything stupid?"

'Now you're just trying to rub it in,' I thought, but out loud I said, "Won't it be awkward to drag me around on your date like a bodyguard?"

"You can just watch from afar. She won't even know you're there. You made the deal remember?"

I sighed giving a slight nodded. "Be a little...subtle with your touches..."

"Sure thing." Issei smirked as he clapped on my shoulder. "Thanks, bro."

"Now get out of my room..." Issei nodded his head before making his way out of the room and close the door behind him.

'Single Awareness Day...Woo...' I mockingly cheered before slumping myself on the bed. 'What could possibly gone wrong?'

[Timeskip]

From the safe distance, I followed Issei and his girlfriend Yuuma like an assassin from a game I love. I watched those two having a fun with their dates. I don't know why but I kept getting more and more sucpicious on how she's act. She really looking like a perfect happy-go-lucky girl you can find in one of games that Issei owned. From shops to the arcade, I kept following them like a stalker, earning some weird glances from passerby. I secretly wished that this could've been my date with Koneko.

After that, Issei took Yuuma for ice-cream while I sat at bench nearby. I saw that my twin about to something stupid. I took a small stone nearby, throwing it at the window. Issei manages to snap from his breast-induced stupor as I give sigh of relief. Then out of nowhere, an attractive curvy woman in bat-themed outfit made her way towards me.

"Here, take a flier," She handed me the flier, winked at me and walked away.

"I could always use a bookmark," I joked a bit before looking down at the flier in my hands. "Your wish will be granted?" I read before putting it in my book as a mark.

From there, the date went normal. They walked around for a while, did more shopping, and eventually just seemed to be enjoying each other's company. Maybe I just too paranoid about this and just jealous. As the day drew to a close and the sun started to set, the two of them wandered off, heading toward the park with me following from behind.

I yawned a bit before tripping on something and fall to the ground. I winced in pain a bit, looking towards the ground and saw a stone statue of a triangle with an eye on the middle and small top hat. It right arm was raised up, like it was asking for a handshake. I became warily about this and about to walk away...but this thing...kind of mesmerizing for a bit. My hand itching its way towards his hand without any concern...like I was been hypnotized. Slowly but surely, I put my hand on the stone hand before my eyes became blind with lights. I closed my eyes-

[Dream]

Before reopening again to see that the world around me stopped. I got a bit confused, looking down at my hand to see that the statue was gone. Completely weird out right now, I stood up from the ground and looked around the area until my eyes glows blue and start spluttering some words.

"Triangulum, entangulum,. Meteforis dominus ventium. Meteforis venetisarium!" The skies turns grey as I began to say in reverse for at least 5 times. My eyes turns normal as I looked up and saw a yellow triangle flouting in the skies. An eye open up in the middle of it before growing a hand and a top hat appears out of nowhere.

"Ah! It's good to be back!" The being happily cheered as he stretched his arms. "Man, this place feels a bit weird..." That thing then looked at me. "Am I right?"

As a normal human being, only one thing was suggested that comes into my mind...scream out loud like you see a freakin ghost which I am currently am. I was about to make the run of it before my feet was flouting the ground. I get a bit freaked out by it as I was forcefully turned around, before looking straight to the eye of the monster.

"Hmm, you did not look that kid from that place..." It place it hand on it's chin? Looking me up down and judging from his perspective. "Where am I kid?"

"Kuoh, Japan!" I quickly answered before he pulled me a little bit closer.

"What did you say? I didn't catch that."

"I SAID KUOH, JAPAN!"

The thing eye widened as he dropped me from those levitation thing, resulting me to fall down to the floor. I grunted in pain before I starting to hear him slowly laugh as it flew up the skies and cackled like a maniac.

"At last, I am free from those family in another universe!" It shouted happily as it looked at me. "Quite weird that I appeared before you. It's like fate intertwined us together like chains!"

And with that, pair of chains wrapped around my arms and legs as it levitated me back up. The think flew down towards me as it gives his hand towards me, which I suspiciously looked at it.

"Bill Cipher, pleased to meet you." That thing now named, Bill cunningly looked at me with those big eye. My hand than were forced to stretch out. I tried to pull it away, remembering all the visions I saw from that lizard. "How about a friendly handshake?"

"Why should I trust you, Cipher?! That thing warned me about you!" I gritted my teeth, glaring at him with anger.

"My feisty one. Remind me of a certain kid...now where was I? Oh right. HAHAHAHAHA!" The yellow triangle demon forcefully grabs my hand as I screamed in fear for what to become...

...

...

...

...

...

Nothing? We both looked in confusion as Bill kept pulling and putting his hand on mine. He became a bit frustrated by it. "Why it didn't work?"

"What?"

"You! Why I can't possess you?!"

I just looked at my hand in confusion as before the place flickered out. "Wait, is that blood? On your shirt?!" The thing exclaimed pointing at a certain area in my chest. I looked down and saw that my body was already drenched in red...blood...I gritted my teeth in pain as the chains loosen up a bit and fall down to the ground.

"Oi, don't you die on me!" Bill shouted in fear as it float towards me, slowly disappearing. "I just made my appearance in the story! Don't you dare die on m-"

The skies turns normal as Bill was gone from my mind. I realized I was lying on the ground next to a now bleeding Issei. I heard someone giggled. A matured kind of voice coming from a woman as I turned my head towards it. I saw what it seems to be 'Yuuma' but with a pair of black wings on her back, giving a sly smiles toward us.

"The actual fuck?" I muttered under my breath as she walked closely towards me.

"I sense such a tremendous power coming from you...it could've been so much dangerous if I didn't deal with you." She smirked at me, stepping on my still bleeding chest. The pain was excruciating as I wish that I already die by now. "You and your brother is just in my way of our plan. I knew that you followed us from the beginning...just to lay on the trap on both of you. You and your brother are threat to us and must be dealt with. If you're looking for someone to blame, blame God for giving your brother the Sacred Gear after all."

"You crazy...ass...bitch..." I coughed some blood from my mouth, glaring at her losing the consciousness...

Third Person's POV

"Shame," 'Yuuma' commented as she looked at towards the (Y/N)'s face. "You're more attractive than your brother..."

Suddenly, he's shot up and glows blue, shocking the lady a bit. He slowly pushed her off with a new found strength as she flew up in the air, maintaining her fight.

"Okay, flying woman isn't in my list of conquering the reality," A different voice rather than (Y/N) said as he held his wounds on the body, which is slowly regenerating. "Took a while to possess this body but I did it! Woo, self-fives!" He claps himself before standing up and looked at 'Yuuma'. "Whoever you are, you're messing with my host here!"

And with that, his hand starts to produces fires and shot it at 'Yuuma' who barely dodged it. He then pointed his fingers like a gun and rapidly shoot fires with flying girl dodges every shot from him. She makes a spear out of light and throw it back at his chest which he casually dodges it with ease.

"Stay still! I'm trying to make a fried chicken!" '(Y/N)' exclaimed in frustration as left eyes shot out laser which slightly graze her right arm, making her bleed. '(Y/N)' then got to his knees, panting loudly as his glowing eyes flickered. "No, no, no! I'm losing him-" And with that, (Y/N) fall back to the ground with a loud thud.

'Yuuma' sighed in relief as she flew away quickly from the place, leaving the two brothers to be dead. Until then, a red glowing circle formed a little away from two brother. Out of the circle a redheaded figure emerged. "I have come," said a feminine voice. She looked at Issei. "You are the one who summoned me, are you not? Since death is upon you, I will gladly take you in." She paused for a moment, glancing between the two of them. "Both of you. From this moment forward, you will live your lives for my sake."

(Y/N)'s POV

"Wakey, wakey (Y/N)~" A voice called out in my mind as I groaned loudly. "Morning has come, get your lazy ass from the bed as you're dead inside!"

Immediately, I got up from the bed after hearing that voice. I panted loudly, looking around my room before planting back on the soft mattress. "It just a dream..."

"No, it wasn't Sherlock." Bill appeared in front of me, floating while crossing his arms.

I shouted in fear as I quickly rolled out of the bed and took my chair before pointing at him. "What in the world is happening?!"

"I don't have any idea but here I am in your mind."

I dropped my chair down before sitting on it. I rubbed my temple, thinking that I probably have a morning hango-Wait, I can't drink alcohol! "I might go insane."

"Yeah, after what happened last time, you probably are!" Bill patted my back, which felt real for some reason.

"Bill am I right?" I asked the one eyed triangle as I got up from my chair. "What are you?"

"Well, I'm actually a dream demon from another universe. Now I'm imbedded into your mind! Incredible right?" Bill then got closer to me as I can see some fire in his eyes, indicating that he's angry. "WHICH I HATE IT! How can I conquer this said universe if I'm stuck in your mind 24/7!"

"(Y/N), what's with you with screaming this day?" Issei comes into my room, looking at me like I was crazy. "Have the weird dream again?"

"Bro, I want to ask you an important question." I cleared my through before pointing my finger at the flying dorito. "Did you see what I'm seeing?"

Issei looked at the direction before looking back at me. "It's the wall..."

"No, this...flying thing?!"

"I don't see anything bro..." My twin walked away as I sat back on the chair.

"It's official...I'm crazy..." I putted both of my hand on my face.

"Well, suck to be you than! HAHAHAHAHA!" Bill laughed at me as he kept on floating. "But really, I hate being in your head."

"Be glad you trapped in my mind rather than my brother." I pointed out as I took of my shirt. "You don't want to see hentai for the rest of your life if you're in his mind."

"Okay, now I'm glad to be in your mind. Handshake?" The demon stretched his hand out, hoping for me to accept it.

"After what happen last time...I decline." I gave him a mocking smile before making my way to the shower.

"Fuck you! Is that how your generation says it? Bah, whatever..."
