I always wondered what the mechanics of "stealing" a hatsu would be. I mean, does he copy the hatsu and then impose some sort of restriction on the original owner? Also, what happens if the hatsu is modified slightly after he steals it? Would the user be able to use this quasi-original hatsu? If they couldn't, then at what point of modification does the hatsu become different, such that they can use it? A cool ability, but in practice it's not so simple.
