Tsukamoto Kagari

Kazuki's younger sister, a few years younger than him.

She looked up to her brother and was very attached to him, but they haven't seen each other since he was imprisoned.

She is strong-willed and has lived her life despite the misfortunes of her family,
but her original lively personality has faded.

She is currently taken in by the Takaida family and attends Kurasaki Academy with Yayoi.

At first, she felt annoyed by Yayoi, who was unaware that she was being taken in as a hostage, and by Yayoi's mother, who warmly welcomed her, but she is gradually beginning to like them less.

After being released from prison, she was shocked by the news of her brother's death and tended to withdraw into herself, but at the same time she was relieved to hear that he was alive, she was also torn between the Takaida family and the two parties involved, which caused her anguish.
