The Special Duty Combat Unit Shinesman

Matsumoto is a young man devoted to his little brother, Yota. Yota is a fan of the "Greatman" TV show, particularly the character, Greatman Red. Matsumoto joins the Right Trading Company because his father was a loyal company employee. He is shocked to learn he must wear a superhero costume, called a "pro-suit", himself. During his job interview, Kyoko Sakakibara asks what color superhero he should like to be. Matsumoto remembers Yota's preference for Greatman Red, and chooses "red".[2] As a curiosity, he shares his name with a real-life actor who is a Super Sentai alumnus, having played Tsubasa Ozu/Magi Yellow in Mahou Sentai Magiranger and Masato Jin/Beet Buster in Tokumei Sentai Go-Busters.

Hayami believes himself popular with women; a "ladies' man". He helps Matsumoto to learn the ways of the Right Trading Company.

Yamadera loves his car, a Montero. He becomes very anxious if someone else is working on it. He believes his color, grey, represents regal manliness.

Ono is a devoted husband and father. He loves his little girl, Tamari. He keeps her photo on his desk and buys her a fish soft toy. He is unimpressed by the team's weapons.

Hidaka is the only female in the team. Although she is an office girl she objects to being sent to get cigarettes or coffee. She tends to accidentally break things by crushing them.

Sakakibara is the Manager of Human Resources at the Good Trading Company. She is also the team's deputy leader. She fantasizes about being a Shinesman herself one day. She dislikes the color of four of the team. Her assistant is Tsukasa Nakamura.

Kasahara is a sweet-natured and timid secretary who is actually from Voice. She came to Earth in search of her brother, who disappeared. Only Sakakibara knows her secret.

Sasaki leads the alien attack on Earth. Despite his leading role, Sasaki is angry at having to pose as a corporate employee. He is also unhappy to be working with his cousin, Shiina.

Seki is Lafure's brother. They are from Voice. Seki once opposed Voice's invasion of Earth. He was brainwashed and now joins Sasaki's mission. He has also forgotten his sister, so when Seki meets Hitomi/Lafure, he assumes that she is a spy. This particular plot point has not been resolved (see the notes below).

Shiina is Sakaki's excitable and ditzy cousin. She never shows any bare skin to men as she states, she would have to 'marry or kill' them. Sakaki is annoyed she has come on his mission. Shiina falls in love with Matsumoto/Shinesman Red and starts to oppose Voice's invasion of Earth. Shiina appears only as an anime character. However, she is drawn in manga form for the accompanying drama CD.
