Tensei Akujo no Kuro Rekishi

Konoha Satou's middle school years were dedicated to crafting a dark history: a fantasy adventure starring Konoha Magnolia, the Count's daughter, and the knights who adored her. When her mother threatens to expose this secret, Konoha's panic leads to a fatal traffic accident. She awakens in the world of her own creation, but as Iana Magnolia, the story's villainess. Now, she must confront the world she wrote, filled with magic and the affections of knights, while grappling with her new identity and the repercussions of her past actions. The anime explores themes of self-discovery and the consequences of one's imagination.
