My Oni Girl

Hiiragi Yatsuse is a kind and selfless high school student, but he has a hard time connecting with his classmates. One night on his way home, he meets Tsumugi, a strange girl looking for her mother. Without much warning, she invites herself to stay at his house. Later, when a supernatural creature appears in Hiiragi's room, Tsumugi helps him escape. She then reveals she isn’t human-she’s an oni, a demon-like being. Hiiragi recognizes the amulet she treasures and agrees to take her to the shrine where it came from. Together, they set out to find Tsumugi’s mother, encountering new people and facing obstacles as they travel.
