Isn`t that a little unbelievable though? I mean, even if we assume that Jiden can bring up a younger Jiraiya, how could he corrupt him? Let` think about it this way. Koji already knows the rasengan, which means that Jiraiya already mastered it thanks to Minato inventing it. So even this `past Jiraiya` is older than we might think. It took Minato 3 years to develop the rasengan. Let`s say that he developed it around 17.Jiraiya would still have been in his 30`s by the time he mastered it. At this point, Jiraiya would know better than to be corrupted.Doesn`t he already have his ideals about the child of prophecy that will change the world and seeks to find it already by this point? It seems illogical for him to be corrupted into somebody against the ninja system, since he seeks for his prophecy to change the ninja world into better.

Unless i got my timeline wrong and Jiraiya didn`t receive his prophecy yet. Genjutsu is also into play, since Jigen is quite adept in it.
