This manga is connected to the "Date A Live" novel and anime series. It focuses on members of the AST (AntiSpirit Team), a specialized unit dedicated to battling spirits. Okamine Mikie admires her superior AST member, Tobiichi Origami, and might even be in love with her. Regrettably, Origami appears to have no interest in her. One day, they find themselves moving toward an explosion that was not triggered by a spirit. Rather, it was caused by a girl named Ashley Sinclair, who transfers to their school shortly after the incident!
