This anime is based on the newly popular manga Dragon Ball Super formally written by Akira Toriyama. The story has expanded quite a bit from the previous Dragon Ball series. Goku and his friends are now facing foes from all over the Multiverse. Previously, Goku activated Ultra Instinct Sign against Kelfa after nothing else was working on her. He activated this technique again because Kelfa pushed him into a corner. After he activates Ultra Instinct, he simply starts to overpower Kelfa. This happens because it increases his sheer speed and strength by many times. The fighters from Universe 11 have noticed how Goku has kept improving over this fight in the arena. Vegeta has also vowed to achieve Ultra Instinct.
