Naoki was an exterminator in his past life. Now he is in a fantasy world. Without any new skills he continues to just exterminate, but instead of exterminating bugs, he exterminates monsters as his job.

How will his life as an exterminator play out?


Kujonin was discontinued due to the author's disagreements with Kadokawa, the editorial department, and the mangaka. Subsequently Hanabokuro's contract with Kadokawa expired in March 2023.

He doesn't want that to happen so he refrains from drawing to much attention. The action ...

Kujonin is not better than the average Isekai. After reading the reviews suggesting as much, I gave it a shot. Its premise is interesting, yes, but the story itself falls into many patterns that place it within the category of "isekai power fantasy."

Here's a list of tropes present in Kujonin:
-MC gains power ridiculously fast and easy.
-MC attracts women without having to work for it; one interaction or trait is sufficient for creating this attraction.
-Women near the MC want to have sex at really weird times.
-MC denies all advances from women for no reason.
-Ecchi is random and over the top; there's no flow to it, ...
