Nice art and interesting premise.
I myself am a perfectionist, completionist, collector and power gamer - so I can relate to the hero somewhat.
The goddess is so high tension though. Though I guess she'd be good as a tsukkomist.
My kind of hero. I remember grinding until i got all the best equipments available in town and ended up being way too overleveled against the next few bosses lmao.
Man, the writer doesn't fall on the usual LN pitfall by making the MC OP for no reason and instead throw us a curveball where he already met his equal.
