Rikuo&#039;s older sister. College student. It seems she&#039;s popular on campus, but at home she&#039;s lackadaisical to the extreme. She treats androids entirely as &quot;things&quot;, epitomizing the attitude of her contemporaries, and detests &quot;android-holic&quot; types. She sees hints of &quot;android-holic&quot; tendencies in Rikuo.    (Source: Official Website - English)

The future, probably Japan. Robots have long been put into practical use, and androids have just come into use. 
Influenced by the Robot Ethics Committee, it's become common sense for people to treat androids like household appliances. Their appearance - indistinguishable from humans except for the ring over each android's head - has led some people to empathize unnecessarily with androids. Known as "android-holics", such people have become a social problem. 
Rikuo, a high school student, has been taught from childhood that androids are not to be viewed as humans, and has always used them as convenient tools. One day Rikuo discovers some strange data in the behavior records of his family's household android, Sammy. 
Rikuo and his friend Masaki trace Sammy's movements, only to discover a mysterious caf&eacute; that features a house rule that "humans and robots are to be treated the same"...

The movie version is the complete version of the story. It includes all the OVAs and completely new scenes giving details on the background story of some characters. 
Sometime in future Japan, androids have been involved in every aspect of peoples lives. One day, upon checking his android's behavioral log, Rikuo, a student, noticed his android's returning times have been odd recently. With his friend Masaki, they found out the place where his android, Sammy, have been visiting: a small cafe called Eve no Jikan where androids and human are not seen as different. Upon talking with the "people" in the cafe and discovering more of Sammy's behavior, Rikuo changed his view about androids and treat them as friends rather than tools. At the same time, elsewhere in Japan, the Ethics committee is trying to impose policies to reduce the involvement and use of androids in society.
