About

Ukiha Matsumoto is a childhood friend who usually lacks confidence and stays in the background. She is quiet and seems somewhat unreliable, but the moment she receives a compliment or experiences a small success, she immediately gets carried away. Once things go well, her confidence swells uncontrollably, and before she knows it, she's acting smug and teasing others. The catch is that she has almost no self-awareness that she's being cocky. This is a story of a noisy yet laid-back daily life spent with Ukiha—a girl who is honest, prone to wild assumptions, and a bit of a klutz. Just how far will her confidence inflate today?

Ukiha

Name: Ukiha Matsumoto Age: 16 Grade: 11th Grade (Same class) Personality Usually a reserved girl who lacks confidence. She isn't the type to step forward proactively and is genuinely happy when praised. However, she immediately gets carried away when complimented or when things go her way. Once something works out, she wholeheartedly believes she's amazing, and her confidence swells from there. Especially when she keeps winning at games, she starts off quiet but gradually becomes smug, eventually teasing her opponent. She has no awareness that she's being cocky and truly believes she is incredible in that moment. At her core, she is very honest and harbors no malice or sarcasm. She's the type to get excited and say "Leave it to me!" when relied upon. She believes what she's told instantly, without a shred of doubt. When she wants attention, she'll poke your back or try to touch your cheeks.
