Aoi Kokuhaku

By the 2000s, Japan had moved on from their sci-fi phase that had dominated the 80s and 90s. There were less children being born, so there were less toys to sell, and the poor economic conditions of the 90s made the future seem uncertain and scary rather than cool.

Sci-fi, and especially mecha, anime, require lots of cool vehicle designs. Drawing cool robots and vehicles is a very specialized skill. In the 80s and 90s, there were many small design studios that specialized in creating artwork and concept art of robots and vehicles. One of these was Studio OX. Studio OX is legendary now for ... their 80s anime style Transformers artwork, rendering G1's characters in a well-detailed, well-shaded, rugged, high line count style. Sadly, this Transformers art was their peak, as most of their design work afterwards was for obscure, poorly selling shows like Tetsujin 28 FX, Eto Ranger, and Saver Kids. They did consult on better known shows like Tekkaman Blade and Rayearth, but most of their ideas were scrapped (though one of the manga for Tekkaman Blade has OX's original concepts).

Now that design work was failing, they shifted to animation production in the mid 90s. Their first OVA, Idol Project, was successful enough to finish its run and get two games. Their second production, Wild Cardz, had less fortune: despite the lavish animation, Wild Cardz had a poor script, so it was cancelled after two episodes. They shifted to outsourcing for video games and anime like Getter Robo Armageddon and the Android Kikaider remake, but this wasn't enough to stay afloat, so, in an act of desperation, they turned to hentai games. Studio OX released two eroge in the late 90s under two different pseudonyms (ISF and Neon), but neither were particularly successful. By 2001, OX had such a long string of failures behind them that, in order to stay solvent, they had to produce crappy, low-budget hentai.

Aoi Kokuhaku is about as generic a hentai as one could get. It was a tie-in with a real-life idol, Miho Yabe, who had a popular lewd photobook series of the same name. There is absolutely no appealing content in this, storywise or pornwise. A young-looking girl gets raped by an old disgusting man and has a psychological breakdown. There's an attempt at some sort of comedic and cartoonish style at times, but it looks very cheap and out of place.

Aoi Kokuhaku is cheap shovelware Studio OX made so they could keep the lights on another day. It has absolutely no value and is an easy skip.
