This something that I wasn't been fully done in this website. A proper Jujutsu Kaisen x High School DxD story. I had one that would have been Yuji and Issei being childhood friends and be best buds, but I thought this would been too formulaic. So I decided to go on another route, I decided to go on with the ideas of Jujutsu Kaisen 0 and we will follow Yuuta Okkotsu.
Now here are some ground parts of this story: Issei, Kiba, Asia and Yuta are all first years so it can match up to the Jujutsu Kaisen part. Rias and Sona are now second years. Jujutsu sorcery is now on the three factions but its not very well known because the users don't want to be affiliate with any of the three. Also, the start of this story is right after the Freed incident so Asia is a fresh reincarnated Devil. This is all I wanted to say, now enjoy.
At the city of Kuoh
Yuuta Okkotsu was new in the city. He had just transfer to a new apartment and was getting some papers signed so he could move on. He had asked his parents to apply there, they thought he was looking for something more academic but in reality he was looking for a place far away from them so they could be safe.
Right now Yuuta was singing off some papers from Kuoh Academy, the school that he would be attending and getting his uniform.
''Ok kid, you just need to sign here and here.'' Said a staff member from the school.
''Sure.'' Said Yuuta singing.
''Your uniform will arrive the next day. We just need to make the right size.'' Said the staff.
''Thanks.'' Said the teen a little tired.
Yuuta had a look of someone who hasn't sleep in days. Mostly because he hasn't. Ever since…she´s been around it was impossible for him to get a moment of piece in his life.
''New school…will be ok this time?" Asked him in wonder.
He looked at one of the things that he always hold, a engagement ring that he got when he was a kid from his childhood friend Rika. However, what was supposed to be something sweet turned into something horrifying.
''Please Rika…be nice this time.'' Said Yuuta begging.
''Stay…with…me…Yuuta.'' Said a horrifying and chilling voice.
The teen just break down in tears. Nobody could ever come close to him otherwise she would attack in horrified manners. He would never forget what Rika did to some people that didn't deserve a single wound.
''I am forever cursed.'' Said him in tears.
He felt so miserable. Ever since he was curse, he felt like he was going to spend the rest of his life alone and in sufferance.
At another location.
Tokyo Metropolitan Curse Technical College.
Two men were talking in a small room. One had white hair and bandages covering his eyes, while the other was an average tall man with some small sunglasses.
''So what is it this time?" Asked a man named Satorou Gojo.
''We got some in intel on a highly powerful kid.'' Said the principal of the school Masamichi Yaga.
''Oh really? What age is he?" Asked Gojo.
''He is about to start the first year of High School.'' Said Yaga.
''Oh yeah let me check it out.'' Said Gojo.
Yaga then gave Gojo a file about the kid that he was referring too.
''Yuuta Okkotsu, 16 years old, male, shy kid. What is the big deal?" Asked Gojo.
''From what our intel has told us he is being haunted by a powerful curse for years. It goes to the point of harming others that want to attack him.'' Said Yaga.
''Wow, either is a great curse or one of the worst ones.'' Said Gojo with a laugh.
''Yes, we don't even know what class it is.'' Said Yaga.
''Interesting. Does he has any ancestor affiliated to Jujutsu?' Asked Gojo.
''We don't know. He has parents and a little sister but he doesn't live with them.'' Said Yaga.
''Oh so he is a loner?" Asked Gojo.
''He´s has been moving from school to school. My guess is not harm others, I guess the kid doesn't have the guts to go rogue and become a ran away.'' Said Yaga.
Gojo felt a little bad for this Yuuta kid. From the picture it seems he didn't had a pretty good life in the last few years.
''Where is he heading now?" Asked Gojo.
''Kuoh Academy.'' Said Yaga which gave Gojo a little smile.
''Oh…that city.'' Said Gojo with a smirk.
''You know of that city?" Asked Yaga with a raised eyebrow.
''Yes, I know of that place. This is one of the biggest supernatural centers in all of Japan. Not only that the youngest members of the house of Gremory and the house Sitri live there. Both with their little armies and trying to act as ´´nice devils´´.'' Said Gojo with a smirk.
The relations between Jujutsu sorcery and the three factions…weren't always good. The Jujutsu sorceress always refused to participate on the war caused by Angels, Fallen Angles and Devils. It went to the point that they challenged each race in combat and it would cause some really big catastrophe in the supernatural world. Specially with someone that is as powerful as Gojo.
''Satorou…'' Said Yaga with an annoyed expression.
''Don't worry principal, I am not going to piss off the three factions. Although I would love to kick Schierze ass again, I know he wants to pass as the cool and badass ´´Lucifer´´ to his little sister. But if they try to attack me…I won't go easy on them.'' Said Gojo with a smile at the end.
''Of course, but don't cause too much damage. The last thing I want is two Devil Kings barging into my office.'' Said Yaga looking very tired.
Gojo just smile at this exaggerated concern. He wasn't scared of devils or even ´´Lucifer´´, he was only scared of one person.
''What else did you know about Kuoh?" Asked Yaga.
''Recently I heard some rumors going around that a powerful sacred Gear has awakened. One of the Longinus, the name is booster gear and I guess you know who resides in that one.'' Said Gojo.
'Ddraig of the Two Heavily Dragons.'' Said Yaga
''Correct, apparently the user is a kid named Issei Hyoudou. From what I heard he is now a devil under Rias Gremory, he can try to take me on…but you know what I can take it.'' Said Gojo with a smirk.
''Fine…but don't cause much of a scene.'' Said Yaga serious.
''Ok!'' Said Gojo with a innocent smile.
The principal just look with a sweat mark on his head, this wouldn't ended up good for him in the end.
At Kuoh Academy.
Yuuta had received his uniform and felt that it looked good on him. However he didn't know if he was going to fit in this school. Everyone looked so happy and cheerful, while he looked so down and miserable.
''Ok, maybe this year I won't hurt anyone.'' Said Yuta to himself.
The teen just passed at the halls of Kuoh, trying his best to not blend inn. However it was a bit hard when everyone seemed so nice, it was time like this when Yuta wondered how his life would go if he was normal.
At Class 1-2
Yuto Kiba was one of the most popular boys in all of the school. His good looks made him an eye candy among the girls of every year. Despite that he wasn't human but he enjoyed the popularity that he got.
''So Kiba is it true that Issei Hyoudou join you and Rias-senpai at her club?'' Asked one the classmates.
''It is. Issei is our newest member.'' Said Kiba with a smile.
''Isn't him a huge pervert? Aren't you worried he might try something to Rias-senpai?" Asked another student.
''I can't say that I am worried because Rias-sama can take care of herself.' Said Kiba with a smile.
''This is so cool. Maybe Kiba-kun can help Issei and make him stop being a pervert.'' Said one of the classmates.
''Oh that would be such a blessing. Can you do that Kiba-kun?" Asked another classmate.
''Yes…but that would take me an eternity.'' Said Kiba with a whisper at the end.
Then the class was about to start. Everyone went to their seats as the teacher arrived.
''Ok class before we start I got an announced. I know this seems random, but this class is receiving a transfer student.'' Said the teacher.
''A transfer student? Uh in this class they are so rare.'' Said Kiba with a smile.
''Come on inn.'' Said the teacher to the new student.
Yuuta took a deep breath and set foot on the class. His presence didn't seen to be noticeable to the other students. He seemed like the most forgetabel student possible with his look.
Kiba on the other hand was horrified. Since he was a devil he could detected other types of energy and the one being sent by Yuta was pretty much…terrifying.
''What that…'' Thought him in horror.
''Introduce yourself young man.'' Said the teacher.
''Uh hi…my name is Yuuta Okkotsu. Is a pleasure.'' Said Yuta with the most tired tone possible.
The class just seemed to even notice him which Yuuta kind felt relived.
''I will go to my seat.'' Said Yuta.
''Well mister Okkotsu, I hope you enjoy Kuoh Academia and all that we have to offer. Is a pleasure to have you as a student.'' Said the teacher.
Yuta just went to his desk and pretty much stay quiet. He didn't want to cause a scene or drawn any sort of attention…he just wanted to be alone for the safety of others.
Meanwhile Kiba was staring at Yuta in horror. He never felt such a terrifying aura coming from someone else. He was almost calling out his sacred Gear but he knew this would be a stupid move.
''What in the world is that?'' Thought Kiba in fear.
He had to remain calm for the rest of class and find Rias imeedialnty.
''I need to inform bunchou imminently about this. Just…what is he?" Thought Kiba sweating in fear while looking at Yuta.
The Knight just try to take deep breaths and not sound like he was nervous. However, something could sense that he was nervous and it was Rika who was glaring at him while floating above Yuta.
This will be the start. Can the Occult Research Club handle a special grade Curse? It will be fun to see the interactions between both series. Also, if I had thrown Sukuna in there then all the others High School DxD villains would just be a footmark. Riser, Kokabiel, Vali, Loki, Cao Cao and the rest, yes I think Sukuna could kill their asses in no time.
Also, if you are wondering if Gojo can take on Ddraig. Yes, he can. I don't care if you give a long ass reason of how Issei could beat Gojo, I don't care. All Gojo needs is just open his eyes and it's all over. Not amount of pervert thoughts is going to give Issei the power boost to beat a guy who can literally kill both God and the Devil, yes Gojo can do this in this universe, and I guess she could do that too in the canon universe.
Thank you all for reading and stay tune for the next one.
