After transmigrating into the world of Ultraman R/B, I take the place of Saki Mitsurugi, who carries a century-old grudge. I wield an exclusive R/B Gyro and a vast collection of monster crystals, while the System strengthens my body. If I take a transformation device, I can command the power of an Ultraman. Unwilling to repeat the original owner's tragic fate of being consumed by hatred, I abandon my obsession with revenge and make dark power my foundation, gathering allies and collecting all kinds of powerful items. Establishing myself in the world of R/B, I make plans step by step and build my forces, traveling across the stars alone to put an end to the sorrowful fate of the past and steadily pursue the grand ambition of uniting the entire universe.
