Yaeko Kouzou

As a member of a branch of the prominent Kouzou family, Yaeko Kouzou deeply admires and adores her cousins. Initially, she harbors a hostile attitude toward Miya, mistakenly believing that the newly arrived, impoverished girl has come to "steal" the affection and attention of her beloved cousins. However, after the cousins help clear up the misunderstanding, Yaeko gradually recognizes Miya's sweet and genuine nature. Though she remains highly competitive and somewhat stubborn, she shifts her stance to acknowledge Miya as her rival and even helps guide her through unfamiliar experiences, revealing a warm, caring side beneath her proud exterior.
