Christy collected

When Madame la Pie adds someone to her collection, they're hers for good as far as she's concerned. Some people, however, don't need to be kept unwillingly - after all, if you're happy to go back in whenever she wants, isn't that just as good?
Given a certain kitsune's love for bellies, it's unlikely that the magpie has to worry about her prize going too far.
