One evening, Katsumi Mikami, an overworked salaryman from a notoriously exploitative company, missed the last train and began walking to a park to sleep.

However, he collapsed from exhaustion right in front of the park, and with the image of a young man trying to help him as his last memory, he lost consciousness amidst the headlights of a car.

Though he was certain he'd been in a city teeming with buildings, he woke up to find himself sleeping in the midst of a vast natural landscape.

It was a mysterious world where various races coexisted.

He wishes for a peaceful and tranquil life in this new world, this time, but finds himself caught up in one accident and mishap after another?!

This is the everyday life story of an unremarkable salaryman from an exploitative company, who has been transported to another world.
