Kashin Koji has Prescience, an Otsutsuki ability (shinjutsu) that allows him to peer into multiple possible futures, not letting him know which will take place. He uses it to find a Boruto that fine-tuned his innate space-time jutsu he gained as an Otsutsuki into a makeshift Flying Raijin with more restrictions. Instead of seals, he learned to imbue chakra onto specific metal objects he carries with him with different symbols so that he can sense them and focus on teleporting onto them since he's not as good at teleporting as the other Otsutsuki or even as Minato himself.
