Rasa, high diff

Bruh kisame has no sealing win cons

Rasa, high diff. If he didn't have increased chakra, then Kisame would win, extreme diff.

It could go either way honestly

Well Rasa's gold dust would turn into mud right because of Kisame using water release and the samehada can absorb chakra. Plus kisame has enough chakra , which is mentioned to be a tailed beast with no tail.
