Haiiro no Megami-sama

Synopsis

Koharu Mizukawa is a second-year junior high girl. She is smart and beautiful, seen as the idol of her school, and she has someone she admires very much. That person is… Anna Tsukishima, a beautiful girl who once killed a man in this town. She is like a “goddess” to Koharu. Believing in Anna's words, Koharu lives a pure life, striving to keep away from evil thoughts and live up to the ideal of her "goddess." But… her stepfather actions are tarnishing her pristine world with darkness, slowly driving her mad―. Where will the girl's prayers lead her—to light, or to destruction...?
