A girl named Inugami Sakuya, dressed in black clothing and bearing an enigmatic demeanor, arrives in town as a transfer student. Little do people realize that under the moon's glow, she sets out to eliminate those plagued by the "Inugami" curse. Men who fall victim to this curse turn into beasts, becoming a danger to women whom they seek to devour. Despite Sakuya's sword-wielding heroism to end their lives, she receives no recognition and, unfortunately, fails to rescue the women in time. Furthermore, the protagonist has to struggle with her personal demons that are as tangible as can be.
