Saienji Mika♀

Yukari's succubus rival and the person who took Masaki's virginity. She tastes bitterness time and time again at the hands of Yukari. Her nature is to get along poorly with her own kind, but she has an old friendship with two younger people. She's greatly interested in Masaki (and his life energy), draining him with half-serious seductive techniques. Since her great-grandmother is a close aide to the queen of the succubi, Mika herself also has a strong sense of duty and great ability. When she fights as a magical soldier, she injects all her magical power into the surrounding battlefield, allowing her to fight evenly with Yukari. When alone, long-distance attack magic is her major weakness. She lives with her Persian cat familiar Mephisto.
