※※Volume 4 of the book will be released on August 25, 2025※※

Aiba Hashiru is a hero summoned to another world.

After defeating the Demon King, complications forced Hashiru to return to his original world, where he resumed his life as a rookie teacher, still possessing his hero's abilities.

However, among the students he teaches, he finds those who battle monsters, aliens, and mysterious criminal organizations—

This is a rather laid-back story about a former hero's life as a teacher, who doesn't particularly hide or hold back his powers.

【About This Novel】

It is primarily a novel told from a first-person perspective.

Occasionally, chapters from different perspectives are included.

It's a story about a former hero operating in modern times (with significant fantasy elements).

While the protagonist has some quirks from his long life as a hero, he is fundamentally a person of common sense.

The setting is an integrated elementary, junior high, and high school for girls.

However, there may not be much focus on school life itself.

Combat scenes generally conclude in an instant.

Harem elements are planned to emerge gradually.

It is highly probable that the protagonist will not make a move on the heroines.

Also published on Kakuyomu.

【The title of the physical book edition is: "The Peerless Chronicle of a Hero Teacher Who Returned From Another World 1 ~Regarding the Matter of My Students Fighting Monsters, Aliens, and Mysterious Organizations~"】
