If you hate the dense protagonist trope you will hate this novel. It's understandable to play dumb with your students but he can't notice the blatant advances of the succubus-like co-teacher, the maid, and the obvious affection of the JD

It's nice that the plot lines of the abyss beasts, the demon king's organization on earth, the alien terrorist organization are all intertwined, kinda hard to talk about plot without spoiling things

One of the things I like about this WN is that the MC does solve people's problems, but only if... more>> the people involved are doing their part. Apparently he was hero-ing too much during his early days in the other world that he deprived the people of a sense of crisis, like "eh, it's fine, the hero will do something about it." Now he's doing that proverb about teaching a man how to fish instead of giving a man a fish

MC is your cookie cutter OP protag. Sometimes he drives me nuts when he's too lenient on his enemies,

Spoiler

like when he let go one of the current demon king's generals like wtf? MC just took the guy's sword and sent him on his merry way, didn't he think that he could avoid some ppl's suffering by just ending the guy in their fight or destroying his magic generating organ

[collapse]
