Ore ga Heroine o Tasukesugite Sekai ga Little Mokushiroku!?

Namidare Rekka’s unusual birthright draws him into stories where he must become the hero and save each heroine. On his first day of high school, a strange girl in a uniform—visible only to him—appears and claims to come from the future. She warns that his rescues will cause serious trouble in the years ahead. Soon, Rekka’s childhood friend Satsuki invites him somewhere, perhaps to confess her feelings, but she is kidnapped before she can. Desperate to help, Rekka is swept into different science-fiction and fantasy worlds, each with a heroine in danger. He must find his way back to Satsuki and save the others while trying to understand the consequences of his well-meaning actions.
