Takahashi Mitsuko

Mitsuko gets in contact with Oyamada in order to have one wish granted: before entering a nursing home, she wishes to spend a night as she was 35 years prior. During that night, Mitsuko mistakes Yume for Kana, her daughter who used to be a violinist and who died in an accident in Vienna. Mitsuko herself used to play piano. [spoiler]Mitsuko's suicide, after the time of the wish is up, makes a great impact on Yume, who falls into a depressive state and is unable to use magic properly for some time.[/spoiler] In the anime, Mitsuko instead asks Oyamada and Yume to turn her house back to the way it was 50 years ago.
