(Y/N)'s POV

"This is very delicious Mrs. Hyoudou." Rias compliment my mother on her cooking.

Koneko nodded her head in agreement as she munching her food.

"Th-thank you very much." Mum said awkwardly.

Currently, Rias Gremory and Koneko Tojo join us on table for breakfast. I heard that mum caught Issei naked in the room with Rias on the bed. I didn't believe her at first but when I see it my own eyes...I swear that I feel like I want scoop my eyeballs right there. I was simply sat there trying to pretend it was a normal day while Issei seemed to be trying to figure out how to handle the situation.

"Issei, eat the meal your mother prepared for you." Rias told him. She sounded so elegant just then, she really is like a big sister. In response he starts eating really quickly, like he haven't eat for days. "Don't eat so savagely. Eat slowly so you can taste the food, otherwise you're insulting your mother." She wiped the soup from his lips with a handkerchief.

'This is stupid.' I thought while slurping my soup slowly, keeping my glare on both of them.

"Yeah, it's like they're happy couple some sort." Bill commented as he was floating above my head while reading a newspaper before burning it up. "It like watching a romantic story of a vampires which to suck to care. How come there's large fanbase of it?"

'I don't want to question it.'

"I-Issei," Dad spoke up in a trembling voice. "W-Where did this young lady come from?"

After hearing this Rias puts her chopsticks down and bows her head to our parents. "I apologise for not introducing myself. It was incredibly rude of me, Mr. and Mrs. Hyoudou. My name is Rias Gremory and I attend the same highschool as your two children."

"I-Is that so? Your Japanese is quite good for a foreigner if you don't mind me saying."

"My father was worked in Japan for the majority of my life so I've been living here for a long time."

Dad looked pleased with this story, mum however wasn't convinced. "Rias, was it? What kind of relationship do you have with Issei?"

'Master and slave,' I joked in my mind, earning a snickers from Bill.

"You remind me of me!" The top hat wearing demon tapped my shoulder, proud of my savageness that I always have. "Have a refill!"

And with that my empty glass refills itself into an orange juice. No one noticed it, but I think Koneko startled a little bit...'Wait, has she been staring at me during breakfast this whole time?'

"For a savage young devil, you're dense like titanium." Bill creates a titanium ball in the air and throw it away...hitting a dog...somehow.

'Is it bad that I was really looking forward to what stupid excuse they'd pull out?' I deadpanned as I continue drinking my juice, ignoring his previous statement.

"Nah."

"We simply have a very close working relationship, Mrs. Hyoudou." I chocked on my juice hearing her answers. I closed my mouth, trying to suppress my laugh at that stupid excuse. With Bill laughing besides me, it doesn't help me at all. Rias glared me before pouting a bit. "Is there something wrong, (Y/N)-kun?"

"N-N-Nothing!" I trembled a little bit before bursting into a laugh and fall down the chair, without caring whatsoever. "AHAHAHAH!"

Rias continues to pout at me as Issei sweat dropped at the situation.

"That's a lie!" Mum accused. "I saw you both in that bed!"

"Issei fucked up beyond any recognition~!" I sang while laughing my ass off.

"And calm down young man, you embarrassing our guest." Mum scolded me. I guess she implied towards Koneko who keep her stoic while eating her food.

"Issei told me he has nightmares so I slept with him to help." Rias kept on lying to my mom.

"B-But both of you were naked!"

"These days everyone sleeps naked when in bed together, Mrs. Hyoudou."

"I-Is that so?" I stop laughing at them when I heard that. I looked at my mum and dad and saw their eyes in blank state.

'They believe with that crap?!' I thought in my mind.

"Hypnotization." Bill pointed out as he floats my chair back on its place, freaking my brother who sit beside me.

I stood up and sat back on the chair. I cleared my throat, and pulled back my stoic face. "I'm sorry for my unprofessional behavior."

"Apology accepted, (Y/N)-kun." Rias gave me a sisterly kind of smile, which honestly...feels calm.

"Now Koneko-chan isn't it?" Mum looked at Koneko who just finish eating her breakfast. "What is your relationship with (Y/N)? Are you his girlfriend?"

Once again I spit out my drink, coughing out loud. "M-Mum!"

"I'm just asking. She seems to be a little bit concerned about you this morning when she came here."

"She is just my underling for our study session."

"That's correct." Koneko nodded her head in agreement. "Senpai is my mentor."

"S-Senpai?!" Issei gawked at her before looking at me. "How come you never told me that you're Koneko mentor?"

"It because I prioritize my brain rather than my dick, Issei." I harshly replied to him, putting down my chopstick on the table.

"(Y/N), bro. Can you teach me too-"

Before he continue to ask me that significant question on joining our study session, I twirled my chopstick around and used it point and hit it on his forehead. With a big amount of force, he fall down from the chair backward, shouting in pain.

"He'll be fine." I reassured everyone as my mum sighed at our childish bickering between brothers.

[Timeskip]

"Now it's all make sense now." I nodded my head as all of us walking to school.

"Yes, I am a Devil and I used one of my powers to manipulate your parents' memories." She replied, still smiling.

"You know that kind of cruel if you ask me. Manipulating someone memory for your own selfish desires."

"For their own good actually," I glanced to my side and saw Bill floated with me. The others looked at me weirdly as they saw nothing but the air in front of me. "Rather have they forget the memory of seeing their son naked in the bed."

I just chuckled softly before looking back at them. "What?"

"Is there nothing wrong with your head whatsoever?" Issei asked.

"I'm fine, dumbass."

"Not very reassuring about that, bro."

We were getting a lot of weird looks from the other students. Well, I say 'we' but pretty much all of them are directed at Issei. Apparently, it's quite the shock that the school's biggest pervert is walking with one of the school idols. We sepearated at the entrance.

"I'll have someone fetch you both later." Rias said before walking off.

I looked at Koneko who stare deeply into me before I patted her head. "I'll meet you later."

"Bring sweets." She ordered me before walking away. I rubbed my nose before looking at a jealous Issei with a glare on me.

I just shrugged at him and walked away, heading towards my first class. I was so deep in thought that I didn't even notice someone turn the corner just before I did and as such I knocked directly into them and fell to the ground. I opened my eyes and looked in shock. I had knocked over the student council president!

"Smooth move there, (Y/N)." Bill appeared, laughing at my stupidity. "Knock a lady over. And I thought you're gentleman."

'Shut the hell up, Flying Dorito.' I angrily thought before quickly standing. I offered my hand to the black haired girl. "I'm so sorry Miss Shitori, it was an accident!"

"It's quite alright really." She said as she allowed me to help her up. I noticed that the vice president of student council, Tsubaki Shinra, glaring at me. 

I bowed my head briefly before continuing on my way. "What's your name?" I heard Sona call out.

"Cipher." I turned and answered her. "(Y/N) Cip-I mean (Y/N) Hyoudou. It's been pleasure to meet you." I continued on my way.

Somehow, some reason. I could hear that she muttered my name...My persona name as (Y/N) Cipher.

"I'm the one who give you that name you know." Bill pointed out with a soda in his hand...and drink it? You know what. I'm not questioning it. "Sound cooler than your actual name."

"True...true..." I agreed as I walked in the class, dodging a matrix style from a double punch from Motohama and Matsuda. "I saw this coming miles away. Ask Issei, he is the one who sleep with her without any string of clothes."

"He's what?!" Both of the perverts glared at my twin who slowly bring up a middle finger. I turned around two give him two with a smug face on my face.

[Timeskip]

The bell rang for the end of school and before we knew it, pretty boy Kiba Yuuto comes in with that creepy smile on his face.

"Oh look, it's the Joker." I called out, walking towards him and gives handshake. "I guess you're our valet?"

"That's right." Kiba nodded his head. Both of us ignoring all the gush from the fangirls in the classroom right now. "Shall we go?"

"Lead the way, Charming." I smirked before turned and motioned Issei to follow us.

We followed the blonde haired charming prince to the old disused school building. "I didn't think this place was even being used anymore."

"It isn't." Koneko replied as she appeared out of nowhere and walked besides me. "That makes it...perfect for us."

"Alright then."

We all entered the building and followed the boy to the second floor where there was a room at the end of the hall. He knocks on the door. "Buchou, I have brought the twins."

"Bring them in." I heard Rias say from inside.

We all enter but I see no sign of Rias or anyone else for that matter. It was then that I heard the shower. "Why do you have shower in a school building?" I asked the white haired boy with curiosity.

"Buchou...uses it...when she can't...have one at home."

"Huh. Convenient."

The room looked creepy as hell. There were candles in all sorts of places and there was this sort of...demonic looking circle in the center of the room. Other than that there were two sofas and an arm chair in middle of the room with a coffee table and a bookshelf with lots of books and occult thing in it.

As Kiba was about to took a sit one of the sofa, I glared at him and said, "That's my spot."

"Well, you can sit beside of me, (Y/N)-kun." Kiba suggested as Issei deadpanned at this situation.

An awkward silent feels the room as we both stares each other accompanied by the water from the shower.

"No," I heard Issei sighed in defeat as he plunged into one of the sofa, opposite to Kiba.

"Why is that?"

We stood there in silence once more..."It because that seat is ideally located both in relation to the heat source in the winter and a cross breeze in the summer. If we going to put a television, it going to be at a direct angle allowing me to immerse myself in entertainment or game play without being subjected to conversation and in fact there's a bookshelf over there, I can take a book and throw it back with a perfect precision."

Kiba sat in silent for a little bit as he tried to comprehends with my logic.

"Just give him the seat!" Issei grumbled under those hand that he put in his face. Kiba got up and sat beside the boy before I sat at the spot.

"Eternal dibs on the spot." I called out with Koneko sitting beside me.

"You can't call dibs on the spot for a couch."

"Eternal dibs is more powerful dibs than any normal dibs."

"And that is?"

"...This spot is mine...forever..."

Issei sighed in defeat while Kiba just sweat dropped, still having that stupid smile on his face. Bill clapped his hand as he once again show up from the ceiling.

"Bravo, you became the most complicating man I ever witness in my entire life." Bill sarcastically said.

I ignored the flying triangle demon and pulled out a chocolate bar from my pocket and give it to Koneko. "Like I promise."

The girl eyes sparkles as she saw the said sweet on my hand and took it away. She opened up the wrap and eat it before looking at me once more. "Thank you, senpai."

"You welcome, Koneko..." I smirked before pulling out a book and put on my glasses to read a book while waiting the red haired girl to finish up her shower.

The shower stops and a voice I recognize speaks up. "Buchou, take this."

"Thank you Akeno." Rias's voice said. I had a slight blush, hearing the voice of my second crush of this school and that is Akeno Himejima. I cover it up with my book, so that no one notice it. I glanced at my brother and saw that he developed a massive blush and a large goofy grin.

"What a lecherous face." Koneko said from besides me.

"Believe it or not, it always looks like that." I told her.

Isse looked like he was about to scold me or something but then the shower curtain opened and Rias stepped out in her uniform. Her wet hair really completed the image for Issei. I looked behind her to see the stunning Akeno with that beautiful smile on her face. I couldn't help but blush ever more and hid it with my book.

"Senpai, you weren't thinking about perverted thing would you?" Koneko questioned as she stare me at me.

"I'm reading book." I cleared my throat.

"You're looking at Akeno-"

"I'm reading a book!"

"I'm sorry for the wait but since I spent the night at your house I never got the chance to take a shower last night." Rias apologized.

"Ara ara. Hello my name is Akeno Himejima. Pleased to make your acquaintance." She greeted politely. Her voice has a quality to it that I'm not sure of, it just sounded right.

"What in the world you actually mean by that?" Bill appeared by my side, startling me from his appearance.

"None of your concern, Bill..." I muttered under my breath, didn't want anyone to hear me talking by myself.

"Look like everyone is here." Rias declared. "Issei and (Y/N) Hyoudou. We, the Occult Research Club, welcome you...as Devils."

"Sounds fantastic." I sarcastically said, and closed the book.

"Here's tea for both of you." Akeno handed both of me and Issei a cup of tea. We both thanked her, but I had a slight blush on my face which is quite noticeable if she look close enough.

I took a sip before smile brightly. "This tastes really good." I complimented.

"Ara ara. Thank you very much. Ufufufu~" Akeno laughed.

Akeno sat down next to Rias and this meeting really got underway. "I'll get to the point right away." Rias said. "We are all Devils."

Issei had doubt in his face but I already knew about this shit, accompanied by the cliché shocking sound from the movie...which I pulled out a phone, smiling sheepishly. "Sorry, my ringtone. Carry on!"

"You should change it." Bill deadpanned at me. He then looked at me happily, "It sure gives us SHOCKER with that sound."

'Puns...why not..." I twitched my left eyes in annoyance hearing it. 'I hate puns...'

Bill give me a mocking gasp. "You hate puns?! How could you?"

'With you living in my head, I'll be hating it more.'

"Your expression says you don't believe me but I'm sure you remember the man with black wings last night, don't you?" She addressed Issei. "That's a Fallen Angel. They are Angels who have been sent to hell due to evil intentions. They are also the main enemy to us Devils. We've been at war with them since the ancient times. We've been fighting over the possession of the Underworld which humans call hell. The Devils and the Fallen Angels each occupy a different part of the Underworld, Devils increase our strength through the pacts we make with humans. The Fallen Angels, however, manipulate humans into hunting down and killing us Devils. When this got out of hand God's Angels came down from heaven to eliminate both factions, this battle between the three factions has been going on since ancient times."

"Sounds complicated yet stupid." Bill responded while eating a popcorn. Like I say, I don't want to ask.

"That kind of story is a little hard to take in. Is this what the Occult Research Club do?" Issei asked.

"I forget, you have the capacity of baby brain on collecting information." And with that, another solid shot to the heart of my twin as I can heard him cringed in shame and pain at the same time. "Its funny how dumb you are."

"Brother...why so cruel?"

"I'm the saltiest man alive, courtesy of (Y/N) Hyoudou." I winked at him, earning some giggles from Akeno and a small chuckle from Kiba. "Sorry that I inherent our mum sass."

"And mine too!" Bill glared at me with his one eye.

"The Occult Research Club is just a camouflage. It is really a meeting place for this group of Devils." Rias told us. Yeah right, this has got to be some sort of "Yuuma Amano." With just two words Rias made me and Issei stop in our tracks. "You went on a date with her, didn't you Issei? And you, Shintaro, spied on them."

"Stalker much?" I glared at her, putting my glass in my pocket.

"If you're joking around then stop now. I don't want talk about her." There is venom seeded in Issei's voice.

"She existed." Rias continued. "But she tried to erase all the evidence of her existence." She clicks her fingers and Akeno produces a photo. "This is her, isn't it?"

"It's her alright if she matured and decide to make a career as a stripper." I inspect the picture while Koneko glaring at me. "Pardon my language but I'm a savage motherfucker Koneko-chan. You should know that."

"That's is not something to be proud of." Bill told me...before laughing while rotating in the air. "I'm just joking! Be a troll to everyone that you set your eye upon to!"

'Will do, Cipher.' I replied, adjusting my glass.

"This is not a human girl. This is a Fallen Angel. The same as the one that attacked you last night. She came into contact with you to accomplish a certain goal, when she reached that goal she erased any evidence of her existence."

"What was her goal then?"

"To kill Issei." Rias said simply. "But it is unknown for me on why she killed you."

"Must be a Yandere then. She did say I'm more attractive than my twin."

"She probably think you as a threat with amount of power you've been spilling in your body."

"Why did she need to kill me?!" Issei yelled at top of his lungs.

"Calm down Issei, you were just unlucky." The red haired girl reassured him. "There are possessors who weren't killed..."

"What do you mean unlucky!?"

"That day in the park you were killed by her Spear of Light."

"But we're alive." I argued. "Why would she target Issei anyway?"

"You know, kind of far-fetch if you tell me. She could have save us earlier...but we wouldn't be together because of her, don't you think?" Bill patted my back.

'I rather have normal life than trap with you forever, Space Dorito.'

"Harsh."

"She approached him to see if there was anything dangerous inside of him. She killed you, Issei, when she found out for sure that you possess a Sacred Gear."

"Sacred Gears are irregular powers that are bestowed on certain humans." Kiba explained. "Most historical figures were possessors of Sacred Gears which they used to make their name go down in history."

"Most of the people who play an important role in the world are possessors of Sacred Gears." Akeno continued.

"Most Sacred Gears are only usable in human society and are of little threat." Rias carries on. "But there are some Sacred Gears that are a threat to us and the Fallen Angels. Issei, raise your hand." She instructed. He raised his left arm. "Close your eyes and imagine the strongest thing that comes to mind."

"Strongest being...?" Issei thinks for a moment. "Son Goku from Dragon Ball-"

"Superman." I interrupted him. And with that, both of us glare like we're going to kill each other.

"We are not having this conversation."

"Superman."

"I said-"

"Superman."

"You know what, fine. Batman."

"Don't you dare-"

"Martha."

"He did not just pull that card!" The triangle demon legit gasped out loud at my brown haired twin brother.

I was about to lunged at him, but Koneko grabbed my hand and forced me to sit down with an immense strength. "We do not talk about that movie!"

"Who is the savage master now?!" He taunted with a toothy grin as I flipped him off.

"Fuck...you..."

"Are both you done?" She asked us, showing us a cold glare which shut my twin up. "Now imagine that person in a pose where he looks the strongest. Now lower your arm slowly and stand up." He did as he was told. "Now mimic that pose. Imagine it strongly and don't hold back." He closes his eyes and I can tell from his blush that he is embarrassed to do it. "Hurry up and do it." Rias ordered.

After a moment's hesitation Issei shouted. "Kamehameha!" Then he stuck both of his open hands together and pushed forwards in the correct pose. His arm was glowing.

"Now open your eyes. The room is now full of demonic power so the Sacred Gear should appear more easily."

The light spreads and begins to take form on his arm. Where the light once was there is now a red gauntlet on Issei's left hand. It looks rather flashy and there is a green gem embedded on the back.

"What the hell is this!?" Issei screamed.

"Judging from the previous conversation I'd say that's a Sacred Gear." I told him with a smirk. That freak out was hilarious. The others chuckled at my comment while Issei looked offended. "Like I said, baby brain."

"(Y/N) is correct." Rias confirmed. "Now that you have summoned it you can use it anywhere. The Fallen Angel, Yuuma Amano, saw your Sacred Gear as a threat so she killed you. You called me on the verge of your death using this leaflet." She took out a leaflet with a similar symbol to the one on the floor on it. Both off us appeared to recognize it.

"Oh, I use it as my bookmark..." I pulled out the same thing from my book, receiving a couple of chuckles. "Clearly useful other than summoning devils."

"This is a leaflet we give out, the magical circle is used to summon Devils. These days there aren't many people willing to draw the circle to summon us so we give these leaflets to people who we think would want our services. The day you got it was the day one of our familiars was handing them out in the business district. On the verge of death you called me, you wished so hard that you called me instead of one of my servants."

"What you dreamed about boning her while you were dying? You have a weird fetish, my perverted twin."

"I did not!" Issei blushed at the comment.

"When I was summoned I knew immediately that you were a Sacred Gear possessor. The only problem was that a Spear of Light kills humans as well as Devils so I decided to save your life and that of your brother. Although now you're both Devils. My Devil servants to be specific." Black bat wings suddenly sprout from the backs of everyone in the room including Issei, I felt nothing though and before I knew, digital kind of angel wings grew on my back, surprising everyone. "That's new...you intrigue me, (Y/N)."

"Well, I was as amaze as you were..." I mesmerized the beautiful wing with a smile on my face. 'Thanks, Bill...'

"Yeah, yeah. Whatever" Bill merely waved me off. "You're not like this devil. You're dream demon...More awesome and powerful than this posers."

'Rude...But cool...'

"Savageness runs in our blood, kid." He tipped his hat.

"Let us introduce ourselves anew. Yuuto."

"My name is Kiba Yuuto. I'm a second year and also a Devil. Nice to meet you both."

"I'm a first year... Koneko Toujou. Pleased to make your acquaintance... I'm a Devil too."

"My name is Akeno Himejima. I'm a third year and the vice-president of the Occult Research Club. Don't let my appearance fool you, I'm also a Devil."

"I am their master from the house of Gremory. I am Rias Gremory. My house holds the rank of Duke. Let's get along now, Issei, (Y/N)."

'Well...this should be interesting. Am I right, Cipher?'

"Yup...more exciting for us..." Bill replied before laughing out loud.
