The weakest (self-proclaimed) salaryman, unconsciously, the strongest legend.

One spring day.

Haru Shiina, a plain office worker working in Tokyo, finds an unfamiliar subway entrance on his way to work.

“Was there an exit in a place like this…?”

He wonders, but when he wanders in, he finds

that it is a dungeon connected to another world.

However, he doesn’t notice.

Monsters → “Is that a person in a strange costume?”

Traps → “That was close! But I managed to avoid it somehow.”

Items → “Oh, I found a nice stone. I’ll make it into a paperweight.” Haru is completely unaware

that he has “incredible skills” and that he is “already S-rank or higher,” and he takes a leisurely “walk” to conquer the dungeon every time. And the world starts to make a fuss on its own.
