A student at Seika Girls' High School. A sukeban. Age: 17 Gender: Female Height: 161cm Weight: 42kg She has short blonde hair, wears a gakuran jacket, and a white paper mask. She sports a black student cap and carries a bat wrapped in barbed wire over her shoulder. A fairly well-known sukeban. However, she is relatively moderate in temperament and tries to negotiate first. She only snaps when someone messes with her turf. She possesses enough charisma to have gathered five loyal companions. She is extremely short-tempered and makes money through shakedowns. She is a strong fighter who has never been injured. She carries a barbed-wire bat that can be lethal if it hits the wrong spot.

One of Momone's companions. Age: 17 Gender: Female Height: 182cm Weight: 63kg Blonde hair with black streaks. Called Poniko because of her ponytail. She wears a gakuran and carries a metal bat. She has a big-sisterly vibe and is called "Poni-nee" by the others. She is the tallest of the six and plays a major role during shakedowns. While she fights with a metal bat, she isn't cruel enough to keep attacking an opponent who has surrendered.

One of Momone's companions. Age: 17 Gender: Female Height: 167cm Weight: 51kg Short blonde bob. Called Pattsun because of her straight-cut bangs. She wears a standard high school girl's uniform and has bandages wrapped around her fists. Physically gifted, she is the strongest in a street fight; even a pro boxer might lose if they let their guard down. She is hot-headed and bloodthirsty. She lacks formal technique but overwhelms opponents with sheer physical dominance.

Two of Momone's companions. Age: 17 Gender: Female Height: 146cm Weight: 36kg Black hair in twin tails. Called Twin because they are twin-tailed twins. They wear high school uniforms; the older twin has a nail bat, and the younger twin has brass knuckles. They are called "Twin" when addressed together, but individually they are "Big Twin" and "Little Twin." Being twins, they fight with perfect synchronization. Both sisters are bratty types. They eagerly pick fights with anyone weaker than them and taunt their opponents.

One of Momone's companions. Age: 17 Gender: Female Height: 155cm Weight: 41kg Short brown hair. Wears a white shirt uniform. She keeps a knife hidden. She has the weakest presence, to the point where people don't even remember her name, so she's just "The Other One." Because she's so forgettable, she's often overlooked when splitting the shakedown money, sometimes getting nothing at all. She seems the most quiet and timid, but she is actually the most vicious and sadistic. She hides a knife and stabs the moment she sees an opening, though she intentionally misses vitals just to prolong the pain.
