Myako loves to brush her hair. In fact, her brush happens to hold a lot of memories for her. One day, Fushihara and Yuurei-chan are curious to learn about the story behind this well-loved item, so Myako begins to recount the tale of how she came to own it. She tells the story about how she, a ghost cat who had never once found a place among humans nor cats, finally found a place to call home. And it begins not too long before Myako and Fushihara met...

It's now summertime. Today, Yuurei-chan is eating the green peppers she hates, so that she can grow big and tall. Meanwhile, Fushihara is blissfully imagining the two with randoseru backpacks over their shoulders, a classic backpack worn by elementary schoolchildren in Japan. Her living together with Yuurei-chan and Myako had become commonplace at this point. However, Fushihara realizes she still has much to learn about the two little ghosts and decides to ask them for their birthdays. Since Yuurei-chan was born around this time of year, Fushihara decides to give her a certain gift...

It's already winter. And with the winter, comes Christmas. When Fushihara explains the holiday to a bewildered Yuurei-chan and Myako, their reaction is a little lacking in excitement. Thinking it must just be because they've never experienced the holiday before, Fushihara tells the two of them that Santa will be coming to their place this year. The two happily write down what they want from Santa in a letter, but what they end up asking for may not be what Fushihara is expecting...

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...?
