Plot
Dr. Akiba, a perverted scientist, has developed a series of gynoid Dutch wives (aka sex dolls). Yuria Type 100 is his newest creation: she has highly advanced artificial intelligence and vast sexual knowledge, and the first doll which can imprint to her master for life upon having actual sex. However, she refuses to imprint onto Akiba, and escapes from his lab. She ends up living with college student Shunsuke Kubo, where she tries to seduce him with the hopes that he can be her master, as however, he regularly refuses because he has a girlfriend and because he sees her as incredibly annoying when she acts like that. The series follows her everyday life as she tries to seduce Shunsuke. Other Dutch wife gynoids soon appear, some of whom were also invented by Akiba, thus making them Yuria's sisters, and others from competing companies. Throughout the series, there are commentaries about the technical specs of the sexual capabilities of the Yuria and other models.

Main characters

 * Yuria is a Yuria Type 100 (ユリア100式) female android designed with the sole purpose of being a highly interactive sex doll. Not wanting to engage in sex with her inventor, she escapes and meets Kubo Shunsuke, who gives her a place to stay. She finds herself strongly attracted to him but struggles with her programming that tells her just to please him sexually whenever she can.
 * Shunsuke Kubo (久保瞬介) is a college student who takes in Yuria, thinking she is a runaway. He treats her like a little sister despite the latter's strange physical advances on him, which he retaliates with different grappling holds from his hobby of pro wrestling to keep her at bay.

Humans

 * Dr. Ayumu Akiba (秋葉歩博士) is the creator of the Yuria series sex dolls, that have the habit of escaping from him once completed.
 * Maria Nakamura (中村まりあ) is introduced as Shunsuke's fiancée. She is the proud daughter of a wealthy family from Shunsuke's home town, and often expresses jealous feelings. Later, she marries Shunsuke and starts living with him and Yuria.
 * Yoshio (良夫) is introduced as 17-year-old high school student who lets Juria stay with him. He enjoys collecting dolls and prefers them over real girls, but his interactions with Juria bother his mother. However, when he turns 18, he officially accepts Juria.
 * Ippei Yamamoto (山本一平) is a university student studying to be elementary school teacher. He incidentally becomes Yurin's guardian. Despite Yurin's attempts to have sex to him, Ippei just sees her as a child and tries to resist her advances for fear of being seen as a pedophile.

Gynoids

 * Juria is a Yuria Type 105 (ユリア105式) model gynoid and the second of Akiba's functional dolls. She has long, dark hair and dresses in a maid costume. Also disliking Akiba's perversions, she escapes and lives as a life-size doll in Yoshio's room but restricts herself from sexually interacting with Yoshio until he turns 18.
 * Yurin in a Yuria Type 108 (ユリア108式) model gynoid and the third of Akiba's functional dolls. She too does not like Akiba's perversions, and escapes, ending up with Ippei. Her child figure is capable of growing and developing according to her user's preferences as long as she is used that way.
 * Yuria Type 1000 (ユリア1000式), is a gynoid created using a special silicon polymer capable of easily changing her form, in a parody of the T-1000. Like her predecessors, she escaped from the laboratory, but without having her personality program installed, and thus she sexually assaults anyone at sight without warning. After attacking the other Yurias, she obtained data from her respective partners and goes after them as well.
 * Lucy is a Lucy Mark II (ルーシーMarkII) gynoid created in America and sent to Japan to be a rival of Yuria. Her specialty is in the American and European market, and is specialized to engage in "hardcore" sex. She is scouted to work as a model and spokesperson, but her sex-driven programming is a constant source of chagrin to her employers, who are unaware of her true identity.
 * Louie is a Lucy Mark 3.5 (ルーシーMark3.5) android created in America. Due to budget cuts the Lucy 3 and Lucy 4 programs were merged, and the result is that Louie has the top half of a woman and the bottom half of a man.
