The guide wanders through the tree sea of another world.

A middle school graduate boy, Minigon Onishima, gets caught up in an otherworld transfer phenomenon that occurs in various places around the world and is stranded in a fantasy world of swords and magic. However, no convenient gods appear. Therefore, he doesn't receive any cheat abilities and gradually becomes stronger through trial and error and effort. The protagonist returns to Japan once, but the government forces him to take a job as a guide to the otherworld, and he guides various clients to the otherworld. It is a story of growth as he responds to the unreasonable demands of his clients—capturing monsters, exploring dungeons, medical treatment, and more. As planned, while the protagonist carries out his work, he deepens his connections with people and beastmen in the otherworld, and may he become the strongest existence called in the labyrinth city to protect them? ＜Notice＞ The map of Mauselian Kingdom can be found in Episode 98: "scene: 96 Training of the Guides."
