Ragna also said he intended to become everyones enemy or some such so Jubei might figure he has to put the boy to the test or slap some sense into him.

It would also give us a Jubei, not a playable one but one as a final boss of act 3. Since he is supposed to be a boss and thus be special and strong, giving him an extremely small hitbox and making him hard to hit (like Happosai from one of the Ranma fighting games) it wouldn't really be an issue since we would expect the fight to be at least a bit unfair. Ragna's reason for saying that he is the "enemy of the world" was not just thrown out for nothing. He was fully aware of what he said and meant and he said it on behalf of someone hes going to protect. Pretty sure everyone knows who that someone is.

So, that Jubei scenario seems inevitable.
