Shizuru Imawano

A mysterious girl who first encounters Kensuke at school and then corners him in the bathroom. She demonstrates knowledge of the sesshseki and threatens him with a gun but then flirts with him. She reveals she has a sesshseki of her own on a necklace. She is a lively and flirtatious girl but is emotionally closedoff and gets angry with herself when she gets closer to Kagura and Kensuke as she is afraid of becoming too involved. She has been forced to kill from a young age and feels that there is no way out of the path set for her as heir to a criminal organization explicitly shown after her elder sister Setsuna kills their father. She is very competent with a gun and is shown to have excellent markmanship from when she silenced Kensuke by intentionally shooting at his forehead in an instant with her arms chained together and only causing a presumably shallow wound on the side of his head. Her handtohand combat ability is equal to Kagura as the two passed out simultaneously after defeating each other. She is shown to be ambidextrous alternating a gun and her knife between her left and right hands respectively. Source: Wikipedia
