Ichika is a 14-year-old Japanese middle school student living in Kamakura, who discovers on the day before summer holiday that a gift from her tutor is much more than a good-luck charm.

She is honest and polite to everyone, including her own parents, and always tries to do the right thing. She detests lying, especially if she finds herself doing it. As a result, her friends often playfully tease her for being straight-laced. Ichika is easily scared, and the thought of ghosts terrifies her, especially when she first sees Manatsu in a mirror they find in the school's oldest building.
