Takane Katsu

Takane Katsu is a loud-mouthed, bike-riding police officer from Osaka with a flair for the unconventional. Often seen riding a chopper and donning a schoolgirl-style uniform, she wields a large wooden sword as a symbol of her leadership over an all-girl biker gang that frequently acts as her deputies. Skilled in subduing her targets, Takane can also expertly throw handcuffs with precision. Known for her fiery temper and strong sense of pride, she despises being indebted to anyone. As the daughter of Osaka's Police Chief, Takane's loyalty is tested when she crosses paths with Jo and her team. Feeling a deep sense of obligation to Jo, she becomes attached to the group and offers her assistance—even if it means going against her father's wishes.
