Mai Kamiizumi, a 15-year-old first-year high school student, sports brown hair tied into twin buns, sharp blue eyes, and a petite 158 cm frame. Her signature witch-inspired ensemble blends traditional and modern elements: a short blue-and-black kimono adorned with a red ribbon and blue floral accents, layered over a crisp white shirt, paired with long socks striped in blue, dark kimono-style shoes, and a white hat marked by a bold blue stripe.

Cool-headed and pragmatic, Mai navigates life with a calculated realism, often masking her true feelings to evade attention. She defaults to aligning with majority viewpoints during disputes, striving to maintain a low profile. Yet her logical mindset inevitably positions her as the grounding force within her spirited friend group, whose antics persistently disrupt her efforts to stay unnoticed.

Guided by her “Seventy points over a hundred” mantra, Mai champions efficiency over perfection, seeking equilibrium in all endeavors. Her downtime revolves around video games, films, and indulging in comfort foods like fruit sandwiches or beef stew, though she avoids anything spicy.

Despite her reserved nature, Mai’s presence often inadvertently plunges her into disorderly escapades, where her composed façade clashes with absurd mishaps, yielding unexpected humor.
