Domon Kasshu is the representative for Neo Japan in the 13th Gundam Fight. He entered the contest to find his brother, Kyoji, and to save his father. Domon was promised that if he won the tournament his father would be released from his cryogenic sleep. His father was prisoned because the government suspected him and Kyoji of making an ultimate death machine. Kyoji escaped to earth in this machine, known as the Dark Gundam. Domon is searching for Kyoji to put the smackdown on him. Along the way, he meets lots of new friends like: Chibodee, George, Argo, Sai Sici, and more. He is also accompanied by his crew member and childhood friend, Rain Mikamura. He pilots the Shining Gundam at the start of the series but later moves to the Burning Gundam. He'll use the Shining/Burning Finger to get him out of the toughest situations. Domon must fight some of the toughest opponents in the world, including his own teacher, Master Asia.
