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.

After his body is pushed to the limit Makoto Hikawa is forced to give up his position as the G3-X operator. Sumiko Ozawa feels that Makoto uses too much force and that he will not sync with the G3-X's AI system, she instead needs a much more relax and carefree person... like Shoichi Tsugami.
