In Monaco, an Akugyo Chojin named Sunshine trained an individual who later became known as the Seigi Chojin of the New Generation. Initially, this person was a sadistic being incapable of feeling pain due to their own unique weakness - their inability to sense physical damage inflicted upon themselves. However, after facing defeat at the hands of Mantaro, they underwent a transformation and adopted a new path as a Seigi Chojin. During the Ultimate Choujin Tag Arc, this individual declined an offer from Seiuchin to form a tag team partnership. As a result, they became the first victim of Seiuchin and Neptunemans advanced weapon - the Optical Fiber Cross Bomber. This attack caused severe damage to their facial skin, leaving them with a disfigured appearance. The attacks of this individual are inspired by chess pieces, specifically the King, Knight, and Rook. They possess the ability to fuse these forms together in a technique called Grand Slam, which combines their normal form with their chess piece-inspired attack styles.
