Kouta Shibaki

Kouta Shibaki is a high school student whose notorious reputation for lecherous behavior has left him shunned by virtually every girl on campus. His life takes an unexpected turn when he accidentally summons Rurumo, an apprentice witch, and becomes bound to her as her contracted partner—a role that requires him to spend years off his own lifespan each time a magic ticket is used. Beneath his shameless and indulgent exterior, however, lies a genuinely warm and helpful soul. As he spends more time alongside Rurumo, a profound emotional bond quietly takes root between them.
