Ayame

She is a domineering personality and seems to relish teasing Taichi, saying whatever she can to get a reaction out of him. However, Taichi suspects that her actions and words do not reflect who she truly is. Although she is a magical girl, Ayame is very different from Yuki and Hikari. She does not draw her power from love, but rather through the manipulation of what she calls ‘negative karma’. Through this power, she is able to control evil entities she encounters.
