Kōhei and Tsumugi go to the beach, but return due to the weather being too hot. They bring some aji fish to Kotori's restaurant, where Shinobu suggests that Kōhei learn how to fillet them. Kotori decides to make namerō and sangayaki, so they can have the fish raw while also having something cooked for Tsumugi. Tsumugi ends up trying the raw fish and enjoying it. Yagi joins everyone for dinner, and surprises them when he admits he can make sweets. Tsumugi expresses delight over her interesting day.
