—Mizunokouji Asuka Mizunokouji Asuka (水乃小路 飛鳥, Mizunokōji Asuka?) is Mizunokouji Tobimaro's younger sister. She inherited her strength, speed, and agility from her mother (that she could uproot a huge tree and run with it) but is quiet and meek. Her mother raised her in isolation to keep her away from men and thus keep her pure. Even her brother didn't know that she existed due to this. The first man she meets is Ataru and the encounter leaves her with a phobia of males. The mere sight of a man will trigger her to go on a rampage causing massive destruction and scaring away the men.
