Worried that the sealed orders dissolves the Harekaze class, Coco launches a petition to prevent it. Coco goes around asking for signatures with little success. After asking Minami, she decides to hold a special event to draw in people to sign it. Coco and her fellow classmates set up a festival and the event is successful. At the designated time, the class assembles to open the sealed envelope, and the orders state that the class has been reassigned to a new ship, the Y469. The ship is equipped and furnished with items from their old ship that was lifted out of the sea. While the ship was going to be named the Okikaze, Akeno is given the right to name the ship and calls it the Harekaze II. The class heads out to sea for their next adventure while paying their respects to their old ship as they pass by.
