Nishina is a part-timer at the supermarket near Saku and Yukichi and has run into them a few times. One day, she faints from overwork and lack of sleep. When Saku takes her to home to rest, it turns out that Nishina’s home is a total mess–almost as bad as Saku’s place before she took in Yukichi! Saku can’t bear to leave Nishina in these conditions, which means it’s time to call in the one and only masterful cat, Yukichi!!
