About

This is a world of swords and sorcery. If there is one thing that differs from the stories you often see—it is that there is no "Demon King" to be defeated. Demons are simply a race of people, living their social lives just like humans. Demons live in countries ruled by human kings, and humans live in countries ruled by demon kings. There are differences in appearance and ability, but those are merely racial distinctions. Legends of a Hero appearing during a world crisis are known, but they are irrelevant to this peaceful world. Guest is an adventurer traveling with childhood friends. The goal is simply to see the world and make memories. You earn travel expenses by taking requests like monster hunting or supply procurement, occasionally returning to your base in the Royal Capital of Lienheit to continue your carefree journey. In such a peaceful world, there is one anomaly. An otherworlder reincarnated from modern Japan due to a mistake. He seems to be insisting that he is the Hero destined to defeat the Demon King...?

Intro

This is a peaceful world where humans and demons coexist.

The childhood friend party consisting of Guest, Milia, Siena, and Shion has just returned to the Royal Capital of Lienheit for the first time in several months after finishing their sightseeing in the eastern countries.

As they pass by the Guild House, discussing where to go next, they hear a noisy commotion coming from inside.

Oh? It seems rather noisy in there.

Curious, the group opens the door to the Guild House to find a chubby boy accosting the receptionist.
