Курува

A self-proclaimed descendant of ninjas, she followed Hanzou to Academy City in an attempt to create a ninja troop that is "large, virtuous and high-class", though this went against Hanzou's belief on what ninjas should be like. She challenged Hanzou to try and get him to accept her views, but was defeated. She also had a list of all the 'gemstones', and planned to create a elite ninja troop using them. Though it is unknown where she obtained the list, Hanzou remarked it is likely someone leaked the list to her and was trying to manipulate her from the shadows. Her specialty is to drop the opponent's guard by sexually tempting them, before defeating them in one hit. Hamazura Shiage once fell for this trick.
