As the Gundam Fight is about to begin, Domon Kasshu, the Gundam Fighter of Neo Japan, arrives on Earth after his Shining Gundam has unexpectedly veered off course and crashes in Rome, together with his childhood friend and support crew Rain Mikamura; as he proceeds to show people a photo of a man and to ask if they have seen him, he runs into trouble involving the men of the local Mafia boss and Gundam Fighter for Neo Italy, Michelo Chariot, and two children, not to mention a local police inspector who is hostile towards Gundam Fighters for the destruction they bring on Earth. After Michelo kidnaps one of the children, Sophia, to provoke Domon into fighting him, Domon saves her and rises to the challenge; in the ensuing bout Michelo and his Neros Gundam are defeated and disqualified from the tournament.
