Ootsuki Koto is Eiji's childhood friend and basically acts like an older sister to both him and Nanako. She's got a mischievous, playful personality—the type who's always hanging around the two of them, cracking jokes and teasing them relentlessly. Despite the constant ribbing, she's genuinely supportive; Nanako often turns to her whenever she needs advice, and Koto's usually got something helpful to say. She's a supporting character, but a pretty essential one for the group's dynamic.
