Yin-Yang Sorcerer ~Called the Frozen Flower Lord~

Kamiya Chitose, age 16. On the very day she moves to Ibaraki Prefecture with her family, she encounters a beautiful demon wearing a white mask. That night, the demon Count Laggy, who devours and kills people, brutally murders her parents—. "Use this." When she puts on the white mask thrown to her, a gun created by imagination appears—!? To bring back her younger brother Chihiro's soul. With that single determination, Chitose attends a night school exclusively for yin-yang magicians. The curtain rises on a dark fantasy.
