Ikumonogakari The Animation

Japan is facing a childbirth problem. Instead of doing anything about it, people are making hentai about it instead.

Story: 7/10

Japan is facing a childbirth problem, so sex ed is very important, if you know what I mean. Students are having sex at school for educational purposes. It's a concept done many times in hentai. However, it would seem that 90% of the population are men because there's only like 3 girls per class. No story reason for why the population is disproportionally male, but because of this, it is just non-stop gang-bangs.

Art: 6.5/10

The animation is solid. Nothing breathtaking, and it occasionally looks bad, but for ... the most part, it's good enough.

Sound: 10/10

Same as always, nobody every screws sound up.

Character: 6/10

The girls are all cute, but the male characters are all technically rapists. Take that how you will.

Enjoyment: 7/10

The entire situation itself is morally questionable. Some of the girls are against doing this, but do it because it is legally required of them. Others give consent to the act, but don't consent to the many things done to them during sex. The hentai itself doesn't take the entire thing seriously, so it's up to you whether or not you should feel bad about what you're watching. Though it's nothing offensive enough for you to not watch it for yourself.

Overall: 7/10

This hentai is pedo bait, there's no other way to put it. The uniforms worn by the characters are stereotipically those worn by Japanese middle schoolers. There's not even a story to consider, just senseless sex between characters that might as well be nameless, and there's a fair bit of non-consensual acts depicted (without warning from the show, the poster or the synopsis, mind you) despite the supposed excuse for what happens in the story being extreme sex-ed lessons. The art is better than many other hentai and even some random shows. but it's wasted on this ridiculous and pointless show.

They said school will teach you about sex, but this is just ridiculous! *Canned Laughter*
Jokes aside, I wouldn't recommend people watch this; the guys in the class tend to overpower the girls and ignore how they want to be treated, which is an awful thing that's even worse when the teacher is right there and does nothing about it. Doubly so with how there's only a male teacher and no female counterpart in sight. I get that it's 'hentai logic' or whatever, but if the point of this is to educate about sex, then maybe have the characters respect the fact that no means no.
Because ... of this and the fact the characters still look fairly young, this hentai gave me bad vibes all around and I'd be wary of people who actually would say that they enjoyed it.
