A random idea I just had:
>The Emperor's New Groove
>Well yeah, nobody's that heartless! (600)
>somehow you can find a way to bring out the best in these people, making them realize the error of their ways and, slowly but surely, transforming them from a brat or tyrant and into an actual reasonable person, and maybe even a friend if you’re willing to be a friend to them. This won’t be easy, and you’ll probably have to go out of your way quite a bit to pull off such a drastic change of heart in somebody else, but even one of the worst people can change just by hanging out with them for a little less than a week.

>Go to One Piece
>Companion Nareno Miu for free
>Have a journey of character development with undercover Imu
>???
>World Peace

Any other ideas of jumps with perks surprisingly effective at solving the problems of far more dangerous settings? I'm curious now.
