Injuu Kyoushi

The "Injuu" hentai series has like 7 different OVAs, and while they differ quite a lot between them in art style and settings, they all share two things in common: schoolgirls and tentacles. I had been putting off watching them, since for me it is one of the most repulsive genres. However, after watching and enjoying La Blue girl and Injuu Idol, I decided to give them all a watch. My conclusion is that the other ones suck, except for this one (kind of).

You'll probably be surprised that this consists of 4 episodes, 45 min each, which feels very long for a hentai. The first ... one, definitely the best, has an interesting and mysterious plot, and the art style is the most detailed. At times, it even looks like Shin Megami Tensei artwork... but worse (of course). I especially liked the protagonist, who is unlike any other lead compared to similar 90s hentais. This is because she is a strong, independent tomboyish girl. Pretty refreshing I must say. A particular thing about this OVA is that it contains mostly yuri scenes (besides the tentacles), which is also quite uncommon.

The other 3 episodes are connected in a somewhat weird way: the 2nd and 3rd episodes take place at different times at the same school, and for the 4th episode, characters of both chapters appear together. Unfortunately, this piece of trivia is the most interesting thing about them. They are just mediocre horror stories with occasional comedic relief. Not bad, but only slightly entertaining.

Angel of Darkness is a good decent hentai, don't get me wrong, but we don't wanna see another hentai with the same plot in almost EVERY episode, despite it being 25 years ago since the hentai came out. I feel that 4 episodes of this hentai is so unnecessary. They should've did only one episode about Mr. Shigimoto and his crazy lab (the cover on the DVD)

Story: 7/10 - The story itself has a good plot and everything, like supernatural plants raping a bunch of high school girls and a antidote being found but it gets more and more boring in each episode (I'll talk ... about it in the enjoyment section).

Art: 9/10 - Despite it being animated around the 90's, the art is still good no matter what. Sometimes the characters look creepy and stuff, but it's anime.

Sound: 8/10 - Most of the sound effects from Bride of Darkness are in this hentai too so it has it's resemblance but the sound is good.

Characters: 4/10 - There isn't that much details about each characters but they feel all the same in each episode, like them being a student/teacher.

Enjoyment: 4/10 - If you like to watch 40-mins of Angel of Darkness of the same ass plot shown over and over again in each episode, then this hentai is for you. The episodes get more and more boring and less enjoyable as you waste 42 mins of your valuable time watching it. Plus the sex scenes get more boring too.

Overall: 5/10 - If you wanna see a good hentai better than this, watch Bride of Darkness.
