The Tidal Breeze's Mischief.When Tomoya brings Ushio to school he meets her teacher, who is none other than Kyou after seeing Botan her pet boar, and the two soon reacquaint themselves. After that, Tomoya goes to work and Yusuke asks him for Fuko to play with Ushio, since they have become friends after all, and Tomoya agrees. When it is time to sleep, Tomoya uses the "Dango Daikazoku" song to lull Ushio to sleep. Fuko arrives at Tomoya's house to play until the evening when she goes back home as she reminds him about Nagisa. The next day, Kyou tells Tomoya about the annual sports day at school where the parents are to participate as well. He is reluctant about it, but Ushio encourages him, which makes him change his mind. One evening, Ushio is taking a stroll to the new hospital by herself and encounters Fuko on her way. When the latter asks why she does this, Ushio says it is for no real reason. The next day, Tomoya is preparing for the meet at the Furukawa bakery, when Ushio is suddenly struck with a fever, much to the others' shock.
