At school, Aiko discovers that all the girls in her circle of friends have already had their first menstruation – save her. After going home to her room, she reads up on menstruation and in frustration punches herself in the uterus. This seems to "awaken" Ma-chan, Aiko's anthropomorphic vagina, who begins coughing up blood. Ma-chan introduces herself and says that she's been with her ever since birth and from now on she's going to assist in her journey into adulthood.
The next day at school Aiko tells her friend that she's now one of the gang.

Note: Aiko no Maa-chan, was cancelled by Comic Zenon from fears of its publisher that the manga could be considered an “harmful publication” under the “Tokyo Metropolitan Ordinance Regarding the Healthy Development of Youths”. She decided to publish her manga through a successful crowdfunding campaign on Fundiy. Thus Aiko no Maa-chan will be published as one volume in 2015.

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 café that features a house rule that "humans and robots are to be treated the same"...
