Let's just say there is a person stronger than everyone in the universe. Read to find out more. *I do not own highschool DXD only my own oc and some of the plot*

Saito Satsujin, also known as the only delinquent in Asahi High School. He never attends classes and is usually found in the rooftop of their school doing god-knows-what. Despite him skipping his classes and breaking a lot of rules, he always passes his exams. Some teachers say it's because he copies from his best friend, Uesugi Fuutarou but no matter what they do to separate them, he always seems to get a high score regardless. Now, Saito Satsujin is second year high school student along with his bestfriend who recently got a job to tutor five girls who attends the same school as both of them. Will these girls learn something from them or will they learn something from the girls? ------------------------------ I do not own the characters who are part of the anime and manga quintessential quintuplets.

Two brothers, Y/n and Issei Hyoudou. Issei Hyoudou died when he encountered a fallen angel. Issei got reincarnated as a devil but Y/n volunteered to join in order to protect his brother from enemies. But the two of them didn't know the power that's within them. The power that can rival or even kill God himself (Pictures of highschool DxD belongs to their respective owners.)

During his battle with Ootsutsuki Kaguya, Naruto Uzumaki is thrown into a new world, one filled with angels, devils, dragons, gods and fallen angels. After being resurrected as a devil alongside Issei Hyoudou, Naruto will do what he does best: cause as much chaos as possible while climbing to the top. Hokage may be out of his reach, but that doesn't mean he can't set a new goal for his life.

During the culling game, Sukuna returned to an undisclosed location to find a tiny baby crying. This was Sukuna's son, Y/n L/n. With the help from Kenjaku, Sukuna sent his some to another world where he can live freely, but his son was sent to the middle of a giant war between Fallen Angels, Angels, and Devils. What happens when an angel comes across the child and takes him in? This is the story of how Y/n became the strongest.

(A/N: This is my first crossover story I hope you will enjoy and also I don't own naruto or highschool dxd.) (Y/N) is the child of boruto and sarada. He is the youngest prodigy and his family is proud but one day an a tragic disaster happened in the world and everyone he knew died, with what he learned so far he use a dimensional transport jutsu. Then he end up in the world of angels, fallen angels devils and other beings, so what adventure awaits for this young prodigy.

A young man died. He got reincarnated by the Supreme God and now he needs to help save the universe! Nothing's mine besides the Story, I guess.

So basically, a character of my own will wake up as Issei, but he won't be called by his given name in this story. He'll just be your plain old Issei but with a little twist by yours truly, I hope. It will start as before canon but later on in the plot, things will change.
