Overview: The Mihara residence, which took Chico, became lively. For Seri, whose parents tend to be away, Chico is a comfort that makes them forget their loneliness. The only thing I don't like is imitating people. On that day, the one who got angry at the imitation chased Chico and fell into the pond and caught a cold. Chiko, who felt responsible for not being able to take an important social test, goes to school instead of herself, but then she imitates skinny again and completely makes Seri angry. Chico was kicked out by Seri, and it was Spank who was forced to do that Chiko. Even though I'm not good at spank!
