Doll Saya follows a guy that is obsessed with a doll he owns, the opening scene is the guy masturbating to and on to the doll. Eventually while he is out and about town he sees a girl that looks like his doll. He then convinces her to come back to his place where he forces her to dress up like his doll and rapes. The story iskind of creepy with his doll obsession and his eventual raping of some look a like girl. Hard to really enjoy when the main character is deranged like he was, but its not the worse story or main character out there either.

The art is definitely sub-par for a hentai, with blob like features on the characters, noticeable missing details, and scenes that are blindingly bright in color that it almost looks life its been washed with brightening filter. The animation also isn't to great, a little clunky and hasn't aged well.

Overall, skip this one. It doesn't offer anything of real quality, and what little it does you can find dozens of other hentai that have done it better.
