Ringetsu the Animation comes off as a typical harem hentai with a slight supernatural twist. At the very center of the story is Naoto Rindo, the male protagonist engaging in a series of complicated relationships. There's a bit a of drama that's involved.
Naoto begins off having sex with the eldest sister Yuiko, who is married, by the way, to Masakazu... her own brother?! I guess it's revenge for being responsible the accident of Naoto's fiance (his younger sister). So anyways, a hint of NTR. After an unsuccessful attempt at pregnancy with Yuiko, Naoto moves in with the Higetsu family where the rest of the 3 sisters reside.
There's the 2nd oldest sister, Shino, who is dominant, proud, and tsundere type. She happens to also be a teacher at the school which Naoto and the two younger sisters are attending, so you know what's going down at school.
Then there's Ayumi, the 2nd youngest sister. She's just right in terms of personality. A shy, but friendly type that cooks, cleans, and makes your bento. Pretty much your perfect girl. I would say the bulk of the story revolves around the relationship of Naoto and Ayumi. But poor Ayumi always gets the raw end of the stick because she closely resembles her dead sister Suzume (Naoto's fiance).
The youngest sister is Mizuna. Your yandere loli type, who happens to be interested in sex ed and "toys".
Although Naoto is rich and handsome, he's some what of a dimwit when it comes to women. He breaks all the rules of sexual engagement.
Rule #1: Don't sneak into a girls room and grope her while she's sleeping hoping to have sex with her for the first time.
Rule #2: Don't call out different girl's name while your having sex.
Rule #3: Don't hallucinate while having sex.
Despite the protagonist being kind of weak, Ringetsu actually turns out pretty well as a hentai. All the characters are pretty. The sex scenes are lengthy with good animation. There are some repeating frames but none you would complain about. (i.e. fap material) It's also available uncensored which is always a plus. You get to empathize with the characters during the 3 part series. There are plenty of schoolgirl play: sailor suit uniform, bloomers, school mizugi, as well as dildos and hot shower scenes. All consensual sex, I might add, though at times, it's a bit painful to watch. But it all ends well for those who don't like guilty faps.
