An Akugyo Chojin from Monaco trained by Sunshine. At first he is a sadist that is incapable of feeling pain, this is however his greatest weakness as his body itself is being damaged, he simply cannot feel it. But after being bested by Mantaro, he turns over a new leaf and became a New Generation Seigi Chojin. In the Ultimate Choujin Tag Arc he turned down Seiuchin's offer to form a tag team. Because of this, he became the first victim of Seiuchin and Neptuneman's Optical Fiber Cross Bomber, resulting in the skin on his face being peeled off. His attacks are modeled after chess pieces for King, Knight, and Rook. He can fuse them and his normal form together in a technique known as Grand Slam.
