After formally introducing himself and revealing Warstar's existence, Dereputa leaves, much to Alata's dismay. After Alata reveals that he has fought Dereputa, the Gosei Angels reflect on the legend of the Gosei Machines. Walking Nozomu home, Alata meets the boy's father Professor Shuichirou Amachi. As Eri and Hyde arrive to the site of Heaven's Tower, the Master Head attempts to contact them with a means to return to the Gosei World. Elsewhere, the Landick siblings battle the Universal Insect Monster Zaruwaku of the UFO and the Bibi Soldiers after they discover that Nozomu and several other people have been abducted. Contacting the other Gosei Angels, the Skick Goseigers arrive to aid them while Hyde manages to receive the Master Head's message. A solar flare that occurs once every 200 years will allow them to return to the Gosei World without the Heaven's Tower. Hyde arrives at the battle, finding the Landick siblings fighting with each other instead of fighting Warstar with the Goseigers of the Skick Tribe. He notifies the other Goseigers of the Master Head's message and then transforms to fight Zaruwaku. After Gosei Blue weakens Zaruwaku, he contacts the Master Head to say that they are staying on Earth. The Goseigers use the Gosei Buster to destroy Zaruwaku, freeing everyone. However, Buredoran of the Comet sends his Bibi Bugs to revive and enlarge Zaruwaku. The Goseigers' refusal to run away enables them to summon the Gosei Machines and battle Zaruwaku's UFO clones before forming Gosei Great to finish the monster off. After the fight, Hyde uses the Memorywash Card to erase the memories of everyone that was abducted to make sure that their mission remains secret. The Master Head watches on from the Gosei World, ruminating that things will not be easy for the Goseigers.
