Manga Like Kamen Boxer

One day, Kenichiro, a commissioner of the Boxing Association, was kidnapped by the "World Domination Gym". Kenichiro returns safely a few days later, but his personality has changed, and he begins to accept the World Domination Gym's demands one after another, even though they deviate from the rules of boxing. As the boxing world is on the verge of an unprecedented crisis caused by boxers wearing the suspiciously approved gear, a boxer stands up to stop the ambitions of the World Domination Gym. Shimamoto's parody of Kamen Rider and Ashita no Joe. (Source: Mangapedia, translated)
