Kare wa Diablo!

Meiko, determined to realize her dream of a romance with her senpai, employs black magic, but her spell has an unexpected consequence. She inadvertently summons the demon king Lucifer, who not only appears in her life but also becomes her homeroom teacher. As part of their contract, Meiko is compelled to embark on a path of witchcraft, only to discover that she is, in reality, bound to Lucifer as his slave. Her new reality is further complicated by the emergence of her magical powers, which manifest in a peculiar way whenever she consumes Anpan, a type of Japanese pastry. Now, as Meiko navigates her complex relationships and supernatural abilities, she must confront the consequences of her actions and the true nature of her connection to the powerful demon king Lucifer.
