From Onadoru Euphoria:

Shinesman is a comedy series that parodies shows like Power Rangers or Ronin Warriors. There were only ever two episodes released, with notably hilarious dubbing for a show. The manga series has 9 volumes and is drawn by Kaimu Tachibana, who often draws BL, so you can expect there to be innuendo or jokes about the male characters being too close.

The main story in Shinesman is that Matsumoto has joined the Right Trading Company, and somehow was picked to become the newest member of a group of superheroes called "Shinesman" (which would sound like "Businessmen" in English). They fight evil aliens who are trying to take over the business world. It's light-hearted and undeniably cute.

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.
