After two years Ultraman Ginga left Earth, and Hikaru returns to Japan once again after gaining a strange vision during his adventure in Mexico.

Alarmed by the theft of the Victorium, the Victorian (ビクトリアン, Bikutorian), a group of ancient civilians that live underground sent Sho to retrieve it and bestow him an ancient relic, the Victory Lancer (ビクトリーランサー, Bikutorī Ransā) that transforms him into their protector, Ultraman Victory (ウルトラマンビクトリー, Urutoraman Bikutorī).

Hikaru was dragged into the battle again after being recruited into UPG (Ultra Party Guardians), an attack team formed by the International Defense Forces after various paranormal incidents.

He reunites with Ultraman Ginga and joins forces with Sho to take down Exceller and his minions.

As the series progressed, it was revealed that Exceller's true agenda is to revive Dark Lugiel from the moon, desiring his body to take over the galaxy.
