Note: This project began as an amateur manhwa on Naver, but became popular enough that Naver chose to turn it into a professional work. The author and artist changed their pen names and restarted the series from the beginning, redesigning the artwork and part of the storyline in the process.

From Yen Press:

The elite and beautiful Ririchiyo Shirakiin has a bad habit—she can’t help but lash out at people with her vicious tongue, all while hiding behind a mask of haughty cool. This attitude has a lot to do with people minding her business because of the Shirakiin family name, but it troubles Ririchiyo to no end. In search of independence and solitude, she moves to the Maison de Ayakashi, an apartment building full of wealthy tenants and with its own Secret Service. Ririchiyo is eager to be alone, but upon her arrival, she is greeted by Soushi, an SS agent arranged for her by her parents. Ririchiyo tries to turn Soushi away, but Soushi’s dogged devotion to his new mistress will not be deterred. The threat against the residents of the Maison de Ayakashi are not to be taken lightly, after all. And despite his puppy-like demeanor, Soushi is not to be trifled with either…

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!

Most surprising, however, is the Water God himself... and how very different he is from the monster Soah imagined.
