Mitsudomoe is awful. The fact that the teacher's voice actor is the same one as Zenitsu from Demon Slayer is already a red flag. Do I really have to listen to this annoying ass voice for the rest of the season?
Ok, enough of that tangent. Barring Zenitsu's voice actor, Mitsudomoe is basically a low-brow ecchi comedy centered around 11 year olds. Sexual innuendos and themes are the at least half of the comedy, and it's just kind of cringe. Either that, or low effort slapstick. I really couldn't get past the first few episodes.
Do the characters really matter when the content of the show is cringe humor? It's basically dangling a key in front of a child sort of humor. Haha, penis joke. It's even more funny since an 11 year old is saying it. I mean honestly, everything could have been saved if the comedy was decent, but no, not the case.
