Miss Shachiku and the Little Baby Ghost

Episode 12

An unknown sender has been sending letters to the apartment every day since New Year's. All of which demanding that they move out. Thinking this is just somebody's idea of a prank, Fushihara doesn't think much of it at all. But then one day, instead of a letter, what do they receive but a package in the mail! Fushihara and the two little ghosts are frozen stiff as something inside the package begins to stir. What might be about to come out...?
