Summary
Kozue, born on May 28th to blood type O, is thirteen years old and shares a twin bond with Miki. She harbors deep-seated resentment toward her brother, feeling both overshadowed by his innate talent and tainted by the constant comparison. Her jealousy is particularly acute regarding Miki’s affection for Anthy Himemiya, driving her to act out in provocative ways, including adopting loose sexual morals, simply to seize her brother's attention. Much like Nanami, Kozue exhibits an extreme brother complex, positioning herself as Miki’s primary protector. This overprotectiveness effectively prevents him from pursuing a romantic relationship with anyone else, despite the interest shown by many of his schoolmates. Kozue identifies as a "wild animal," expressing a desire to escape adult rules and restrictions. While she frames this as a quest for freedom, it is fundamentally rooted in her bitterness over her father’s remarriage.
