Klein's greatest wish is to transmigrate to another world and live life in an isekai, just like in anime, manga and novels.
However, fate is on his side and the typical truck that the main characters always carry in isekai runs over Klein.
But, to his bad luck, he lived a few more days in the hospital and, just on the day he died, Klein heard a ⟨⟨-DING-⟩⟩ that he knew it meant.
That was the day of his death, but also the beginning of his adventure into another world.
