I’ve always loved these little details in shinobi striker where moves that are otherwise unstoppable can be negated or even overcome with jutsu that make sense to. For example, Kamui vs. another kamui ability or Naruto’s truthseeker orbs vs Sasuke’s onyx chidori since both use six paths chakra.
he needs to be in his little circle and to land a hit to make that bond thing in the first place, so no. Canonically speaking, he can do nothing to kamui
Once you’re using the ability, the second u press an attack button u become hittable, at that point we didn’t think of actually attacking eachother lol; my apologies brudda !
