Tokumu Sentai Shinesman Manga Summary
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.
From Mangascreener:
Ever seen a little show called Power Rangers? Or any of its relatives stateside or around the world? Well this is a mix between a parody, a satire and a tribute to all the greatness of Super Sentai all rolled into one... with a twist. This task force of heros have jobs, a boss and a 401k. Set during the bubble economy of the 1990s, this campy but loveable manga brings office comedy to a classic genre of super hero shows. If you have a chance, the anime is released in the United States (all 2 episodes) so go check it out, and get ready for the manga!
