Now, coming to our main topic about which I’m here to talk about is that what and who could Kashin Koji turn out to be? The most common assumptions are that he is either Jiraiya himself or he is Jiraiya’s son. But I have a theory that makes much more sense and even has a great deal of possibility to be true than these mentioned assumptions.
Well, I want you all to recapitulate when Jiraiya was shown with his Genin team which included Minato Namikaze, the Fourth Hokage of Konohagakure. Nothing about the remaining two Genins has been shown yet, even their names haven’t been disclosed yet. What if Kashin Koji is actually one of the members of Jiraiya’s team. We don’t know anything about the other two teammates of Minato Namikaze that were alongside him and Jiraiya in the picture.
