Tougen Anki: Nikko Kegon Falls Arc

Still reeling from the death of his adoptive father, Shiki Ichinose discovers he's part Oni — which would be wild enough on its own without the grief piled on top. Now he's enrolled at Rasetsu Academy, a school built specifically to train descendants of Oni to control their powers. The headmaster is someone whose real face nobody has seen, and Shiki's classmates all carry their own baggage — Jin, a quiet guy whose father is descended from Momotarou (yes, that Momotarou), and Homare, a girl dealing with a rough family history that goes beyond just the supernatural stuff. This sequel arc, set around the Nikko Kegon Falls, picks up where the first season left off and digs deeper into the mythology side of things. The power system is blood-based, which gives the fights a visceral edge, and the show leans hard into actual Japanese folklore rather than just borrowing surface-level aesthetics. If you liked Blue Exorcist's academy setup or the way Jujutsu Kaisen blends dark themes with its action, this hits a similar nerve. There's also a Naruto-esque found-family thread running through it as Shiki bonds with classmates who all have complicated relationships with their heritage. The tone stays pretty dark — don't expect lighthearted school comedy vibes here. It's more about kids figuring out what it means to inherit something monstrous and deciding what to do with it.
