Classroom of the elite x Demon slayer, Kiyotaka as main character, the story starts in year 2, after the lastest volume (volume 9). Ayanokoji clan will be the descendants of sun breathing, people dont die at 25 with marks, and even though they will be descendants they wont have the marks on their faces constantly they can activate them and deactivate, they will all also have another breathing style in addition to sun breathing. The students Sakura, Yamauchi and Katsuragi haven't been expelled. Kiyotaka was raised in the white room with his sisters Kanae (Kocho) 17 years old, Shinobu (Kocho, who will have strong enough arms to decapitate a demon and will use flower breathing) 16 years old, and Manjiro 11 years old. The whole school will go and train to fight demon's at the Ayanokoji estate (there wont be a picture of the house but it's big enough to fit all students and teachers and staff, and it's of course a Japanese style house). The siblings will know their mom and have a good relationship with both their parents, Ayanokoji Atsoumi and Yuuki. There will be breathing styles and slayer marks, there also might be some lemons if i feel like it.
