This one is very forgettable. All I remember is a huge creature appears out of nowhere, (maybe the sky?) to destroy the city, and the military attempts to fight it off.

It cuts to a couple having sex. Then it cuts to another woman being raped.

The animation is terrible, the "story" is terrible. The cover art fooled me. I thought it would be at least halfway decent, boy was I dead wrong. Do not watch this.

Story: 3/10

Art: 4/10

Sound: 4/10

Character: 3/10

Animation: 2/10

Fap Meter: 2/10

Dyogrammaton… I sadly do not have much to say about this title other than it is just bad. The characters have bad hair, most characters you feel you have seen somewhere before in a better quality story. It is also plagued by mixing in poor quality 3D shots along with average quality anime. The hentai portions of the series are sluggish and lack a lot of in-between animation, so it feels like a bunch of stills being run together instead of a smooth animation. I honestly felt cheated by the animators and think they must of used every trick in the read more

This hentai is a result of 2 fan boys who know nothing about art, girls, or sex getting together to make a hentai. Don't waist your time.

Sadly I purchased this hentai :(, as a impulse buy. The cover looked great, and I had gone and entire month with out anything. Why didn't I look at the review first? why?
