Kiyo Doujouji

Kiyo is a girl who first appeared at Misao's school, asking her to stay away from Kyo because she wanted him instead. ~!She is, in fact a snake demon who tried to poison Misao. She warns Kyou that if he sucks the poison out he could die, but Kyou does it anyway, much to her surprise. She escapes while Kyou is helping Misao. She (along with her brother, Kensuke) later helps Kuzunoha try to take Misao away from Kyou, but she finds out Kuzonoha tricked her, as he planned to kill Kyou, something she didn't want to happen as she still desired him. During the ensuing commotion where Kyou finally killed Kuzonoha, she escapes again.!~
