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