Shizuku is the younger sister of Kanade and Yukinos. While she appears level-headed compared to her sisters, she is deeply affected by Kanades actions and cares about him more than Yukino. Unlike her sisters, Shizuku hides her emotions but they surface later in different ways, such as cutting school. She also exhibits passive-aggressive behavior. Despite Yukinos efforts to get closer, Shizuku ignores her attention, possibly due to jealousy over the time Kanade spends with Yukino instead of her. Shizuku seems aware of the deeper relationship between her sisters.
