Review Detail of TheGentleMan in This Hero is Too Curious!

Totally recommend this story. The author is going for a light novel vibe, with the epic fight of Hero vs. Demon King, with complications. In this setting, the Demon King is in the final stages of winning. The MC hero is just one of many sent over to stop him, but the others usually give up. Anyone who likes isekai stories should read this. This is better written than most of the other isekai stories out there.
