Kashin Koji seems to be a pure ninja. He doesn`t use any ninja tools, and (at least until now) he seems to have his original body, with no technological amps.

A big part of Ao`s body had to be reconstructed with technology.

Jiraya was missing and arm after the pain fight, namely his left arm. KK seems to have his left arm natural.

It would be pretty lame if KK will end up having no link with Jiraiya, since the toad summing and the rasengan are too much of a plot twist, but for him to be Jiraiya it wouldn`t really fit.

I think he will end uo being yet another student of Jiraiya, and perhaps it was Jiraiya the one who taught him the rasengan and how to summon toads.
