Yuuko Kanoe from Tasogare Otome x Amnesia

The Enigmatic Ghost of the Old School Building. Yuuko Kanoe is a mysterious and ethereal figure, haunting the halls of an old, abandoned school building. Once a student, now an apparition, she is bound to the building by the echoes of her past life. As a ghost, she is intangible and in constant need of others' memories to maintain her form. Her appearance is often shrouded in shadows, and she has a penchant for wearing traditional Japanese school uniforms, giving her an air of innocence and youthful charm.
