I've started reading TGWOK back when it was still going.
Revisiting it decade later was a mistake.
You can't enter same river twice, and you can't enjoy bad series when older.
As a kid, it was a silly time filler, and my taste in Japanese comic books was really bad apparently.
The story is that Keima, a young sociopath impassive in common life, just wanting to play his simpleton dating sims, bumps into Elsie - a bottom dreg demon from hell who's mentally challenged.
"Hilarity ensues" as the unconventional duo deals with shenanigans, dating "real women" (other teenage girls), and it just drags for ages instead of ending in a maybe 2 volumes as it should.
Art is is acceptable. Characters are not. Gags are gagging with how boring and formulaic they are.
It's a product of its times, back when harems were still "hot", so not worth reading if it isn't 2010s.
