This is the first chapter of my new highschool dxd fanfiction sorry for all of those people wanting to see the next chapter of my other one but I wanted to try out a more phycopathic issei and im not too sure if I want to add my OC darkshot but if I do I know it will be appropriate but without further ado enjoy. Also he has a OC family. I don't own anything but my OCS and plot.

*Issei house*

It had been ten years now since isseis biological family had died in that mysterious accident and nine years since he had finally found a new family and now it was starting to look up for him as he had a new brother new mother a new father and a two year relationship with a girl named sophie.

It was a cold December it was actually the coldest December in years but that did not bother Issei as he had a huge night planned out for him as he was now sixteen and was going to be joining a new school Kuoh academy soon but that did not matter as tonight he was going to have a very fun night with this girlfriend sophie while his family set up the remaining Christmas lights.

*2 hours later*

It was now 7:55PM issei was talking to his brother while they both played some call of duty. (Issei's younger brother is only two years younger and is called Logan.)

"hey Issei is sophie coming round tonight and also new years eve." said logan while shooting some AI in the head.

"ye but I feel like tonight will be very special compared to new years." said Issei as he watched his brother get a five man with a grenade.

"Oh whys that planning to lose your V card today and don't worry you will have privacy and I will be able to keep mum and dad outside till 9:00Pm so you better start before then and close the door as that will turn your voices into quite whispers." said logan while giving issei his trade mark evil smirk

"ye thats what the plan of action is for today but if it does go wrong then I might die of embarrassment." said issei twitching nervously.

"She is a ten so I think you have only a 50% chance of getting it to work but I have faith in you bro and you might want to go to your teeth bro she will be here in under a minute and your breath stinks like mountain dew and there are mints in my draw just in case and also im sleeping on the couch tonight so if you want you can get her to spend the night im sure I can convince dad and mom." said logan while standing up and turning off the console.

"Thanks for having my back bro ill thank you for this in the morning." shouted issei as he ran up the stairs grabbed his toothbrush and started to brush his teeth till he heard a knock on the door so he grabbed a mint from his brothers draw and ran down the stairs and opened to see his girlfriend sophie in a wonderful scarlet dress and a handbag and just by looking at her issei nearly fainted.

"Hey you look amazing."said issei blinking just to see if it was real

"Th..Thanks I just hope I didn't overdue it but this is only the second time I have met your dad so I want to make a good impression." said sophie as she pointed her toes at the floor and started shivering from the cold.

"Oh sorry come in it must be freezing out there my parents are just getting the decorations from the shed and my brother is helping them so come in no one will be back in for an hour." said issei trying to get her to come out of the cold. Just like he had hoped sophie came in and sat on the couch and looked at the console wondering if she could have a go quickly as she had only ever played it once as she did not own one and this was Isseis brothers so she was never allowed on it as he was always on it when she came round.

"H-hey Issei can we go on your brothers xbox for a bit as I really want to 1v1 you at call of duty." said sophie looking at Issei with puppy dog eyes

"How could I say no to that face." said issei as he tossed a controller at sophie and picked one up before loading up call of duty and then starting up a custom game and loaded up a match on rust.

20 minutes later sophie landed a 720 on issei off the building in the middle and humiliated him 30-1.

Isseis mouth was hanging open as he considered himself at least top 10 at his old school but now he looked like an idiot.

"How about we go up stairs and talk for a bit." said sophie trying to get isseis attention

"ok lets go." said issei ready to make his move.

As the two walked up the stairs and into isseis room they where both nervous of the same thing at that was what the other would say to their question.

"Hey I want to ask you something." they said in unison

"lady's first." said issei nervous at what she was gonna ask.

"i-I-I want to take are relationship to the next level as we have come to that age now." said sophie as she turned her head away and had a huge blush on it.

"well I was actually gonna ask you the exact same thing so I think we should get started before my parents come back in don't you." said issei with his confidence back only getting a nod from sophie and they started their activaties for the next hour

{SORRY ABOUT NO LEMON I JUST WAS NOT IN THE MOOD FOR WRITING ONE AND WILL DO ONE LATER IN THE STORY}

As Issei and sophie had finished their buisness they heard the front door open and three people come in. Relief hit issei at this point in time as he knew he had gotten away with this and just finished in time. Ten minutes later Issei heard footsteps coming up the stairs and the doorknob of his room turning to open. Issei thought his life was over as he had his girlfriend lying next to him naked asleep and as he did not want to wake her he sat their and waited for the person to come in.

"nice you actually did it im proud of you." whispered Logan as he entered the room

"what are you doing you made me think that was mum or dad." whispered issei back to his brother

"oh sorry about that just came to pick up some pajamas oh and you might want to get her to wear some pajamas as well just in case mum or dad walk in." said logan as he picked up his PJ bottoms and top and walked downstairs to the couch and went to sleep.

"Psst sophie wake up." whispered issei to the beutiful girl laying next to him

"huh issei what is it." said sophie seeing that her lover was staring at her with a pleasant smile .

"i was just wondering if you could put on some pajamas incase my mum or dad walk in." said issei handing her some of his pajamas

"yes thanks but that doesn't seem to be something you would come up with as it was pretty smart." said sophie giving him a grin

"hey ill have you know I am smart but no it was not my idea it was my brother logans." said issei knowing this would cause sophie to get paranoid

"W..Wait you mean Logan saw us like this what if he tells your parents and makes up break up or even worst what if he saw me naked." said sophie blushing madly.

"don't worry about it me and my brother have a really good relationship and no he did not see you naked you where under the covers and he woke me up when he opened the door to get his pajamas as he is sleeping downstairs tonight." said issei laughing at his blushing girlfriend.

"ok I will believe you on this one but I think im going to get some sleep." said sophie closing her eyes and falling asleep.

"Goodnight sophie." said Issei noticing she was already asleep so he decided he should get some sleep as well.

*In Issei's Dream*

[HELLO BOY] said a menacing shadow creature.

"who are you and is this a dream." asked issei looking at this thing

[WELL MY BOY YOU ARE MY FIRST PARTNER I AM OBLIVION THE GATE KEEPER AND ULTIMATE WEPON OF THE OBLIVION] said the shadowy creature

"Ye but why am I dreaming about you." said issei looking at oblivion with a confused look

[I AM HERE TO WARN YOU THAT IF YOU DON'T WAKE UP NOW YOU WILL DIE IN THE NEXT 5 MINUTES AND ALSO I HAD TO REVEAL MYSELF SOONER OR LATER SO WAKE UP BOY] said oblivion as Issei jolted awake.

Foot steps and banging could be heard from outside and when issei approached his window to look out he heard his mother and father scream and a bunch of men laughing. At this Issei woke up sophie told her she should keep quite and hide while he went to help his parents but before he could open other two had scaly bat like wings with glowing spears in the black feathered wings mens hands and swords in the others hands.

[BOY SHOUT MY NAME IF YOU WISH TO SURVIVE THIS FIGHT] said a voice inside his head

"wait Oblivion is that you." thought Issei

[YES NOW SHOUT MY NAME BOY BEFORE ITS TO LATE] said oblivion seeing that only one person in this room was going to survive and that was issei as the men had already grabbed sophie and impaled her to a wall.

"SOPHIE." shouted Issei as he tried to run and help her.

[BOY LAST CHANCE CALL ME OR DIE] said oblivion in a demanding voice

OBLIVION shouted issei as two black katanas appeared in his hands and he impaled two of the four men.

"That little shit." shouted the one that impaled sophie to the wall as he saw his friends lifeless bodies on the floor

[YOU MUST ALL PAY FOR YOUR SINS ANd FOR TAKING THE LIFE OF THE ONE I LOVED NOW DIE]

OBLIVIONS PURGE

And with that a burning red light evaporated everything in the room apart from sophie and issei

"sophie wake up talk to me." screamed issei as he looked at sophie but to no response. As the light spear faded issei picked up the lifeless sophie and walked downstairs only to hear the voice of his brother shout.

{CARNAGE SLASH} and with that issei saw three corpses of the same type of bat winged men fly across the room.

As Issei rushed round the corner he saw his brother holding up the last one by the neck and asking him questions like what he is and why.

"We we are devils and we were sent by lucifer himself." said the last devil begging for his life

{how pitiful of a devil like you to die by me} said logan while cutting the devils throat with his new gauntlet that had spikes coming out the knuckles.

"Logan is that you." said issei as he put his katanas back into their mindscape

"Issei thank god your alive but how and what happen to sophie." said logan deactivating his gauntlets and rushing over to see her condition.

"Shes dead and im gonna go bury her in the garden next to the fountain and you may also want to do that for mum and dad as well." said Issei crying as much as he can as he just lost his lover and his new family. With that logan wrapped his brother into a hug and whispered that he would and everything would be fine.

As they got to the fountain the saw it was already sunrise and that they had alot of work to do but as they started issei said,

"Logan how did you even survive I only survived because I have a power called Oblivion." said Issei looking at his brother trying to understand their situation.

"Oh I have something similar but his name is called carnage but he also told me I have another power with in me but I will have to unlock that through training first." said logan finishing the first hole.

"I've actually not spoken to Oblivion yet but when I do I want to find out if I can be as cool as you and have two powers." said issei trying to lighten the mood for both of them.

[ACTUALLY AS A MATTER OF FACT YOU DO] said a new voice unfamiliar to logan

"so that must be oblivion huh." said logan looking at the two katanas on Isseis back

"yep but we will talk about that some over time but lets go get the bodys and put them in some freezer or something as a replacement of a coffin and preserve the body's till we get a coffin." said Issei as he sat down on the fountain then looked over to his brother.

"ye but we have to visit the new school tomorrow and tell them that we wont be joining the school." said logan looking sad

"Ye and maybe we can find some devils while on the way and kill them for mum and dad." said Issei looking over at his brother. What the two didn't realise is that when he said this they both made a silent vow to kill all devils and supernatural that stand in their way.

*Next Day on the way to the last day of School and Logans and Isseis first*

"So we should tell them that we will only be doing one say at school and that will give us time to find any devils or other supernatural and then meet up at lunch on the roof and discuss what we have found as I doubt we will be in the same class." said Issei looking at his brother who wasn't wearing his school clothes but a black tracksuit black jogging bottoms and black combat boots with a black scarf wrapped around his neck given to him by his mum and black finger less gloves.

"you have to remember that I am in the same year as you even though im two years younger as I am the same IQ as you so there is a chance but we are here so stop talking about it and try blend in." said logan acting calm

"kinda hard when you arn't wearing the uniform." deadpanned Issei.

"still can fit in but lets head to are classes what class you in im 2-B." said Logan

"Can't believe it we are actually in the same class." said Issei as he face palmed at the luck they where having today.

As they got into class they took two seats in the back and near the window and waited for the teacher and students and when the teacher entered and saw them he asked.

"Are you boys the new ones starting here today and why is the younger one not wearing uniform." said the teacher pointing at logan

"sorry but we are from a poor family and they can only afford one at the moment sorry sensei." said Issei letting a tear drop from his eye at the mention of his mother.

"ill let it slide today but please go wait outside so I can introduce you when the others arrive." said the teacher as the two stood up and walked to the door not before logan said

"Save us those seats tho teach."

As the bell rung and all the students took their seats the teacher introduced Issei and Logan.

When they walked in all the girls screamed and the boys gave them death stairs.

"Does anyone have any questions for Issei or Logan." said the teacher looking for any questions and all the girls hands shot up wanting to ask issei the same question. "yes aki." said the teacher pointing at one of the girls.

"do you have a girlfriend Issei or Logan" said aki and with that all the glass In the room shattered and Issei walked out the class with Logan saying sorry and following after him as the teacher knew that must have a dark past behind it and was going to let that slide just for today.

"Oy Issei want to go look around the classes and look for supernatural beings while we now have this free period and will help you on are mission." said logan trying to cheer up his brother.

"Sure lets start with the higher classes lets walk into them look and just walk back out and lets start with the third years then lets check second and lastly first sound like a plan." said Issei with a wicked smirk like Logans.

"Thats the worst plan I have ever heard but im all in for it." said Logan as suggested they check 3-C first as that had the hottest girls in the school in but surprisingly Issei said yes as he had a feeling they would be devils. When they opened the doors of class 3-C they saw that the teacher was asleep behind his desk and the girl know ans shouna was teaching and when she looked at Issei she saw something that would haunt her for years. The smile of a killer. With that Issei sensed alot of powerful devils in the class so he walked in the room stood on the desk of the hottest girl in the school Rias Gremorys desk and punched the roof causing it to crack and the sprinklers to go off making all of the students in the class leave but the devils Issei and Logan.

"who the hell do you think you are and who are you I've never seen you before." said Rias as she stood up from her seat and stared at issei doing a angelic smile. When Issei saw the smile Rias was giving him he laughed and so did Logan they laughed so much the devils left in the room looked at them like they are insane.

"Such an Angelic smile and good looks for a fucking devil." said Issei regaining his composure and shocking all the girls in the room.

"how did you know we where devils and what do you want a fight." said Sona looking at Issei and Logan

"no we just need some information and that is who is lucifer and where do I find him." said Issei as he heard Rias mutter under her breath the words brother. "must be are lucky day Logan we just found the sister of lucifer may as well start should we not." Said Issei looking at Logan earning a nod and before anyone could react there was a screach of death and then time stopped for everything but for Logan and Issei.

"How did you do that Issei that was impressive." said Logan

"Oh I opened an Oblivion portal using Oblivion and it froze time for everything that lives in this world or hell and only heaven didn't get frozen so only them and us are unfrozen." said Issei full of confidence.

"may as well kill this Rias girl and this sona girl but lets just wipe that Akenos girls memory as having her as a personal slave of mine sounds fun." said Logan with a sick smile imagining never having to do chores ever again.

"fine but lets also leave a message for all those to see and that should be LET THE WORLD FULL INTO OBLIVION AS CARNAGE MUST BE FREE," said issei proud of himself for that line

"ye I like it and lets also write it in blood oh how that will leave a good sign for the devils and anger lucifer." said logan pulling out carnage and slashing sona all over trying to cut her in every place possible.

"ye I like your idea of the blood but what im going to do with Rias is so much better than yours." and with that issei cut all of rias clothes off and then cut off her privates and head and stuck them to the wall before wiping akenos memory and renaming her miley and then looking over at the other devil and thinking that issei may as well have a maid and wiped her memory before calling her lucy and before they left they saw a bright yellow circle appear and out of it came four angel like people three guys and one girl.

"Who are you weird glowing people." said Issei looking at the people who where from heaven.

"We are the four seraphs of heaven and we came to see what froze everything but the heavens when we sensed the power of oblivion from this building we came to investigate and were preparing for a battle but it looks like you were not here for a fight so what are you here for." said the female Seraph.

"Just turn around and look." and with that Issei and Logan disappeared and the Seraphs only tuned round and where shocked to see the little sister of sirzechs lucifer decapitated and little sister of serafall in a million pieces on the wall with the message LET THE WORLD FALL INTO OBLIVION AS CARNAGE MUST BE FREE on the wall in their blood.
