Janus no Kagami

Ozawa Hiromi (Sakurai Hinako), a kind-hearted second-year high school student, lives with her strict grandmother Takako (Kokusho Sayuri) and her late mother’s older brother and wife. Grieved by the loss of her daughter, Takako’s education for Hiromi goes too far. Hiromi is robbed of her freedom by her grandmother and her high school life shrinks. Hiromi likes Shindo Kenichi (Shirasu Jin), the president of the student council. But at one point, Takako learns of Kenichi’s existence. In a fury, she locks Hiromi up in a storage room as punishment for the first time in years. An old mirror in the room triggers Hiromi’s flashbacks of the past and she faints. When she wakes up, she has changed into another person, Yumi, with a completely different personality.
