It's surprisingly good. I'd had low expectations, thinking "it won't be as good as Interviews with Monster Girls" and "that's mildly disturbing about monster girls trying to become human and losing school points if they slip back into being themselves". Here's a quote from Episode 1:

"Here, you learn to feel, think and act like a human. Unhuman-like behaviour and rule violations result in point deductions. In other words, it ends up on your report card."

The problems include... 1. "anime monster schoolgirls" is a recognised sub-genre and at first glance this looked unimpressive, especially compared with some of its predecessors. 2. The art's a bit cheap-looking. 3. The protagonist (Hitoma-sensei) is fairly bland, since his "misanthrope" trait doesn't mean much even in the first episode and quickly gets sanded away. 4. I had a bad feeling about those memory-controlling ring that can give you amnesia. 5. Ultimately, this is yet another anime about a male protagonist surrounded by cute girls and big boobs. There's some pretty ridiculous cleavage, albeit only from a minority of the girls. 6. Any show dangling the possibility of teacher-student romance is at risk of creeping out the audience.

I've got a nasty feeling that this anime might have killed the original light novels. It should be great news when your manga/novel series gets an anime adaptation. You're expecting a sales boost. You'll be making big plans for the future. However, this anime aired in January to April 2026 and its original light novels released their fifth and final volume in March 2026. I'm merely speculating and I could be wrong (e.g. a child/sequel series might be imminent), but that's not a good sign.

Personally, though, I liked this show. It's stranger than it looks. Its school was established by a monster girl for the sake of girls like herself who want to become human. It has transformation artefacts so that, say, a mermaid can walk instead of being a fish below the waist. Also, their idea of "monster" is broad. Sometimes, it's normal (werewolf, harpy, oni, dragon). Sometimes, they're stretching boundaries (elf, cat, mouse). Once, they had me boggling. (I won't spoil the surprise.)

The show goes really fast. We're not halfway through when suddenly there's a graduation ceremony and, eh, does that mean a year's passed? One girl achieves her goal and disappears from the series. That's the first light novel (episodes 1-6)... and two more volumes get crammed into the season's second half. Each year/volume introduces more girls, more oddity and more problems for Hitoma-sensei. The showrunners could have built twice as many episodes (or more!) from all that, but I get the impression that instead they cherry-picked the best storylines. Quite a few of these episodes are genuinely decent. Their emotions resonate. I particularly liked:

(a) Isaki the werewolf, whose issues make sense but I'd never seen them explored before with werewolves. Their resolution is fairly obvious, but still nice. I liked episode 3's ending. The only downside is that Isaki's use of a slightly childish Japanese speech pattern is annoying in a situation where you don't know which personality she's referring to. Anyone with a brain would have spotted the problem and started saying "this me" or "that me".

(b) the rabbit's story, which has at least three twists I hadn't been expecting. Her identity, the person she wants to meet, that person's current situation... I admire the writer who thought up all that. There's a conversation you'd never expect from anyone. This storyline's emotional beats sneaked up on me and hit me surprisingly hard.

(c) the bird is likeable, but her goal is disturbing.

(d) Episode 11 is uncomfortable. We know where it's going, because we'd already heard Hitoma-sensei talking about it. It's why he became a misanthrope. That's yet another storytelling colour in this quietly odd series, adding something different again to the last few episodes.

(e) the lying oni who's probably my favourite character in the show. I want a second season just to see more of her.

Quite a lot about this series will lower your expectations. The art's middling. I could have lived without the mouse's "chu" gobi. Big boobs will get pressed against Hitoma-sensei's back on a semi-regular basis. (Clothed, but even so.) The dragon schoolgirl proposes marriage on sight, adding that she'd like two children, and never really stops asking. That said, though, I liked her. She has a surprisingly effective story and I actually wanted more of her in the show.

That's this anime all over. It's generic (the premise) and trashy (the boobs, although there's no nudity), but it also kept surprising me.
