Yuria is a humanoid sex doll. She is a female android designed with the sole purpose of being her master's sex slave. However, she has one flaw: she does not want to be a sex doll. After escaping from her creator, she meets Kubo Shunsuke, who gives her a place to stay. Hilarity is bound to ensue as she battles her programming, which draws her towards him, and pretty much any other man she comes across.
