She grew up with her father by her side most of the time. When she got her first boyfriend, a disembodied spirit of her father arose and would interfere between them, as he was overprotective of his only child. So she asked her recently enrolled teacher Annette’s help, although Annette hoped for Rinne to solve Manami’s case for her. But she managed to identify the spirit’s identity with her Scrying Orb, and Manami got mad at her father, whose spirit returned to himself as soon as he became aware of what he brought upon.
- She appears more often as Sakura's classmate in the anime.
