Hero Sensei: My Students Are Fighting Monsters, Aliens, and Mysterious Organizations~(LN)

Synopsis

The Academy Where I Found a Job Was a Home Away From Home... Where My Hero Powers Were Essential

Aiba Hashiru was a Hero summoned to another world. After dealing with some unforeseen trouble following the Demon Lord's defeat, Hashiru managed to return to his original world—with all his Hero abilities intact—to resume his life as a rookie teacher.

However, among the students in his class are girls who secretly battle monsters, aliens, and a mysterious international crime syndicate...

This is the story of a laid-back former Hero's teaching life, where he sees no reason to hide or hold back his world-saving powers.
