After being flushed down a toilet, 15-year-old Yuuri Shibuya is transported to an alternate world called the New Demon Kingdom, and is told that he is to be the new king of the demons.
I don't expect much, but it's still disappointing to get into the third season and find that after 100+ episodes, the main character has had no noticeable development/maturity. It's listed among 'harems' (and not 'boys love'), but he's only engaged or married to a guy. A couple of the supporting character are likeable and it has comic moments, but that's just not enough to even be mediocre.
