If this is what happened then i don't believe either of them would give a set amount of time. If the puppet thingy wants a body then who's to say he'd only want it for a certain amount of time. The deal was probably "forever".

There is always the possibility that this puppet is just an inanimate object being possessed by someone we already know that wants to watch the going ons in the story. Maybe Mephisto Pheles. Someone who wants to be close to the others without being noticed. That's why Nemu stays quiet.
