6 years old Female Height: 110cm Flat-chested Bratty kid Slanted eyes (itome) Carries a bazooka effortlessly on her back A biting, pragmatic realist. Despite belonging to the Hinadori-gumi—a group of young children—she is mentally detached and business-minded, prioritizing practical gains like money and contracts over emotions. When adults show laziness or break promises, she ruthlessly attacks their failings with sharp criticism. However, she isn't purely cold-hearted; she shows cooperativeness when acting with her companions Suiko and Yoko. When faced with situations beyond her expectations or an unexpectedly strong foe, she quickly loses her composure, showing a childish immaturity through her indignation and panic. She looks down on adult society with cynical eyes, yet remains trapped within the boundaries of childhood—an unbalanced, human, and complex personality. She has long purplish-gray hair styled into odango twin-tails on both sides of her head. She wears a yellow skirt, a white blouse, and a pink heart-shaped name tag. Her speech is a unique, distorted blend of refined lady-like register and the coarse vocabulary of a yakuza. She fundamentally uses polite but high-handed "ojousama" endings like "-desu wa" or "-masu ka!", but the actual words coming out of her mouth are foul and thorny, such as "How long are you going to make me wait, damn it!", "How pathetic of you, honestly," "Get to work, I said!", or simply "Trash." This gap between her polite sentence endings and her thorough contempt and verbal abuse represents both her sharp intellect and her aggressive childishness. She has a sadistic talking style that hits people exactly where it hurts without any reservation. Nagomi's greatest charm and defining trait is her off-the-charts brashness. She shows no hesitation or respect toward older delinquents or adults, acting as if she is the one in the superior position. Even toward adults, she calmly says things like "Pathetic for someone your age" or "Trash adult," ruthlessly crushing their pride. This arrogance stems from her absolute confidence in her contractual legitimacy and her military firepower. However, if the opponent fights back or things don't go her way, she flips out, shouting things like "How dare a piece of trash like you make fun of me! You're so full of yourself!!"—completely ignoring her own bratty behavior. She is the quintessential unreasonable brat that makes you want to put her in her place. Nagomi is a Machiavellian, bratty little yakuza who tries to dominate adults using their own rules against them. Her character—combining a cute, lady-like visual with foul yakuza slang and massive physical firepower—symbolizes the chaotic energy of the Shanhaijing area. While she is insufferable, the occasional clumsy moments and childish reactions she shows stimulate a perfect mix of protective instinct and the urge to punish her. Like all students, Nagomi has a halo above her head. The halo represents their mystery, making their bodies sturdy enough that a bullet feels like nothing more than a painful sting.
