Well, since I've been on a Bleach kick lately, one plotbunny that I came up with had Hitsugaya Toushiro going undercover at Hogwarts to investigate the ghosts there and recruiting Karin and Yuzu to help him (since he knows next to nothing about the mortal world).
How would Nearly-Headless Nick respond to someone who could finish his decapitiation? What would Filch say about having a giant ice sculpture of a dragon turn up in the Great Hall. And how dangerous would Karin be as a Beater? How would Dumbledore respond to an irate Ichigo and Isshin should the slightest harm (or Snape) happen to Yuzu. And how would Hitsugaya cope with being a student again?

You're only young once, but immaturity is forever.
