Summary: An above-average hentai with some semblance of a plot. There is no actual incest; not even of the stepsister variety.

Story: 7/10

Kudos to the animation studio for not deviating from the plot of the game. The story is about a high student student named Takumi whose father suddenly declares to him that he now has two sisters. They are not officially adopted by his father, and he shares no distant blood relation to them, hence the no actual incest. In a nutshell, the story deals with his getting to know his "sisters", and his two neighbors, who also have the hots for him.

Art: 10/10

First of all, the 10/10 rating I am giving this is based on hentai standards, not anime. I feel the two are such different categories (especially when it comes to story) that it's not right to judge hentai in the same way as anime (though I will admit many hentai still annoy because of their idiotic plots).

Story - 8/10

The story of Aneimo (which despite it's name has no incest) is a fairly standard "harem-romance" story (at least for a hentai). The main character Takumi's father has just let two teenage sisters stay at their house and now Takumi is supposed to consider them his step-sisters read more

The story was definitely a modern(realistic) romance. Not just with one girl but three others. There was step incest. Although i was surprised with four girls that the main character got not one scene of a threesome or more. Not even a naked mishap such as one girl undresses ready to rock his world at the same time as another. Something else worth mentioning maybe it was just my copy but the LIGHT THE LIGHT! why so bright? yes, i know the sun is bright but no need for that especially in the sex scenes. I might need to go check my eyes later.

I absolutely had to write a review about this series. Most amazing series for this genre, given only 60 mins and the usual code for sexual scenes.

Overall score 8 for some sort of reality and mild plot, and 9 for the total, for the ending. This series has some sort of conclusion about its harem, which is pretty rare seeing how many harem series usually put it in a stalemate by then end. Especially when this series is an OVA, is short and is a H series.

Strong point- starts well, ends well

Well, about half of it is sexual scenes, and there actually is very little read more
