One night, while Fushihara is working overtime at the office, she hears a scary voice from out of nowhere, commanding her to leave. She tries to ignore it and get on with her work, but then suddenly her monitor turns to black, with the word "Leave" repeated on it endlessly. When a frustrated Fushihara goes to look for the owner of the scary voice, what does she find but the little baby ghost, Yuurei-chan! When Fushihara explains to her that she can't leave until she finishes her work, the little ghost replies earnestly, "Then I'll help you! So you can leave!"

There's no more food left in fridge at home, so Yuurei-chan and Myako head to the nearby shopping district to buy groceries. Nervous and with a shopping list given to them by Fushihara in hand, the two embark on their first ever errand. However, their shopping trip comes to a halt when the fishmonger happens to be a scary-looking man and Myako can't seem to find the words to ask for the fish they need. Thankfully, an old friend comes to save the day...

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...?
