The Boonboomgers participation to the Big Bang Grand Prix was interrupted with the appearance of the Universe's No. 1 monster, Universe No. 1, which caused a universe fusion, causing numerous parallel worlds to begin merging. On Planet Shaft, Bitter Demon Beast Galaxy Circuit Guruma appeared before Taiya Hando / Boon Red. Hoeru Tono / Gozyu Wolf rushes to his aid. Meanwhile, the Gozyugers are fighting Universe No. 1 who arrived on Earth. Boon Blue, Boon Pink, and Boon Black returned to aide the Gozyugers, but the No One is strong and defeated our heroes. Hoeru returns and transforms into a new form, Saint Gozyu Wolf! Vowing to "stop the battle", he tears through space, sending the eight flying to another dimension. Thanks to the information coming from Shirabe and Bouquet, the Gozyugers and Boonboomgers learn that the universe fusion continues and the world will collapse. They must defeat the No One at all cost.
