Just as the others encourage Minami to call her family over to tell them properly, Shut, who has been given one final chance by Dyspear, uses the Sea Castle to summon a Turtle Zetsuborg. However, Minami's determination to protect the ocean allows her and the other Cures to defeat the Zetsuborg, restoring the Sea Castle and another part of the rainbow. Afterwards, Minami goes to meet with her family to tell them about her new dream, receiving their full support.
