Kaijin Reijoh

Asuma Sudou is determined to change his lecherous habits to pursue a romantic relationship with a specific girl. He gains entry into an all-girls school where she studies, hoping to experience a pure high school romance. However, the school is actually part of a covert organization that combats kaijin—monsters born from human aggression. The female students use relics from defeated kaijin in their battles, but the relics' violent tendencies risk consuming them. Asuma finds himself uniquely able to help the girls regain control when the relics begin to overpower them.
