Jiraiya The Hero (Goketsu Jiraiya)
After multiple viewings, downloaded from different sources, I can now confidently proclaim: I have no idea what's going on here. But with a ninja changing into a frog and doing disappearing tricks, and beaucoup kabuki-type highly stylized martial arts (though not fast-moving, still best viewd at slower speed to catch the precision of the movements), it is definitely worth “x” minutes of viewing, for some positive integer “x” significantly less than 21.
