Shizuku Minase

Arisa's adored older brother. While seemingly unemotional, rarely initiating conversation and scarcely changing expression, he cares deeply for his beloved younger sister and treasures her above all else. Their relationship has only deepened with the absence of their parents, and he tries to fill her loneliness with presents and kind words. He guides Arisa to her new home as the Black Rabbit. However, in this new form, he insists that he has no siblings and claims to not recognize the name Shizuku at all. (Source: Ero + Dere)
