Just imagining Kazuki's situation gave me laughs

Well the story is nice but, can you explain some things about the world? The story doesn't seem to have an explanation to the world itself. The adventure of Kazuki the reaper? Hahahahaha plus he pulled out the legendary sword and is an airhead? He's like half hero half villain but the dense type.

Is it just me or is the MC really OP?

Why?!?? Why did you stop it? It was getting good. I love how he's a plague doctor but he actually graduated medicine. It puts a twist from the original concept of plague doctor. Hope you continue this novel
