Date A Strike, デート・ア・ストライク

The manga you are referring to is related to both the "Date A Live" novel and anime series. It centers on members of the AntiSpirit Team (AST), a special squad tasked with combating supernatural entities known as spirits. In this particular story, Okamine Mikie harbors strong feelings for her superior teammate, Tobiichi Origami, which may even be romantic in nature. However, it seems that Origami is not interested in pursuing any sort of relationship with Mikie. One day, while on a mission to investigate an explosion that was not caused by a spirit, the group encounters a new transfer student named Ashley Sinclair, who arrives at their school shortly after the incident.
