S11·E22 Fateful Showdown

Seeing Aki Sakaki dead in the hands of Agito, Ryo Ashihara mistakenly believes he killed her and attacks Agito as Gills. Agito, Gills, and G3 have a heated battle resulting in the G3-System being damaged far beyond repair. After the battle the police department say that the new G3-System, G3-X, will have to compete against Toru Hojo's new system, the V-1 system, to see what suit will be used against the Unknowns in the future.
