Fushihara and Yuurei-chan have taken a black cat named "Myako" in from the rain. But it looks like Myako isn't just any ordinary black cat. To their surprise, Myako is actually a bakeneko, a ghost cat from Japanese folklore that is able to transform into a human. Myako takes on her human form, so that she may repay Fushihara for her kindness, and Fushihara gladly welcomes her into her home. Later, when Fushihara is doing overtime at the office, Yuurei-chan and Myako begin fighting over who gets to help her with her work...

One night, Fushihara discovers that her next-door neighbor Kurahashi-san has been living with a little ghost maid called Lily. Owing to the fact that they can both see ghosts, Fushihara and Kurahashi-san quickly become friends. While Kurahashi-san leads a slovenly lifestyle working from home as an illustrator, Lily spends most of her days scolding Kurahashi-san in utter disgust for her slobbish behavior. Despite this, the two seem to be getting along one way or another...

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...

The streets are covered in a blanket of snow. Even though Myako can't stand the cold, she can't help but feel jealous when Yuurei-chan goes to play outside in the snow with Fushihara in the snowman outfit she bought for her. After concealing these feelings from the others, Myako stays behind to house-sit for Fushihara when suddenly Yuurei-chan appears excitedly back from outside at the front door. She's brought a little something to lift Myako's spirits. But what might it be...?
