Shizuku Sakurai

Shizuku Sakurai (櫻井 雫 Sakurai Shizuku), nicknamed Shi-chan, is the younger sister of Yukino Sakurai and Kanade Sakurai who hates being apart from her sisters and she is a lot more level-headed than her sisters. She is deeply affected by the actions of Yukino, who she seems to care about more than Kanade. Unlike her sisters, Shizuku buries all her emotions deep down without expressing them but they later resurface in various ways, such as her skipping school.
