Saki Mitsurugi

While escaping from the Balsas Gang (バル スー味, Barusasu Ichimi), they crash land o. Planet 0-50, near the Crusader's Peak, which Grigio believes is fate. They meet Frau (フラ ウ, Furau) in a hut at the base of the mountain, and she tells them they would need oxygen inhalation devices (酸素吸入装置, Sanso Kyūnyū Sōchi) to climb up the mountain. The Balsas Gang appears and takes Frau hostage, but the three siblings beat them. Unfortunately, they unleash Margodon, who they have no chance of beating. They decide to put the only oxygen inhalation device on Frau, not wanting any third party to get hurt because of them, and climb up the Crusader's Peak, but were stuck in a dilemma whether to attack from there or climb down the other side. Suddenly, the Ring of Light appears to them, giving them the Gyros and R/B Crystals, which they use to transform into Ultraman Rosso, Ultraman Blu and Grigio Bone to defeat Margodon, the Balsas Gang and rescue Frau
