- After two years Ultraman Ginga left Earth, Hikaru returns to Japan once again after gaining a strange vision during his adventure in Mexico. Once he's arrived, he discovered a new threat in the form of Alien Chibull Exceller, an alien who steals Victorium (ビクトリウム Bikutoriumu), Android One-Zero, his android enforcer and his alien minions. 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 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 join forces with Show to take down Exceller and his minions. Ultraman Taro returns as well, having sensed the new threat and supports Ginga through the Strium Brace (ストリウムブレス Sutoriumu Buresu), which allows him to become Ultraman Ginga Strium (ウルトラマンギンガストリウム Urutoraman Ginga Sutoriumu) with the power of the 6 Ultra Brothers.
