It has the same problems as most of these like, male gaze, recycled set pieces, critical levels of sappy wish fulfillment, not much to say. But it also has ✔ some actually interesting characters ✔ a critical view on dehumanizing demons ✔ interspecies marriage (there's a delivery scene where the kid is too large but then the mother transforms into her wolf form which is much bigger so it's fine) ✔ lots of cute girls ✔ surprisingly competent political writing, and worldbuilding twists ✔ nonbinary djinn elf domme ✔ pretty fun deadpan humor
Anyway the deal is the kingdom just summons lots of guys isekai-style to be their hero, but our protagonist has too shit stats so they send tell him to fuck off. Later when he reaches level 2 he suddenly gets access to infinite mana and instant access to any magic system that touches him???
Instead of helping the kingdom he just flirts around with this high-ranked demon general he finds kind of hot. You can read it here maybe - mangadex
