I just realized the author of this has done two other Isekai works. Eiyuu Kyoushitsu and Jichou shinai Moto Yuusha no Tsuyokute Tanoshii New Game.
The former has that main character with the half white half black hair that doesn't have many chapters, the latter is pretty blatant softcore porn about the hero getting truck-kun'd a second time.
Doing three different Isekai works... that's just cheating, isn't it?
He also did GJ Club, which got an anime.
