Tsukuyo Aoba

As the middle child among the three Aoba sisters, she lives at Mikazukiji Temple while attending high school. Fiercely competitive and deeply guarded by nature, she initially harbored strong hostility toward Akagami Mitsuru due to her family's reputation and a series of misunderstandings. Though her day-to-day demeanor is cold and cutting, she privately holds her elder sister in great admiration and carries a genuinely tender heart. Through her growing interactions with Mitsuru, she gradually lowers her walls and opens up, establishing herself as one of the most iconic tsundere heroines in the series.
