Starting Colored Season - S1.E12

Angelina, Airi and Sakuno see what they think is Pannya around town, but soon realize that it was in fact Pannya's mother. The Nuko Club members go to where Miu first met Pannya and see Mamanya (Pannya's mother) and another smaller Pannya-like animal with her. The club members realize they have to let Pannya go back to its family, though this weighs heavy on Miu most of all. Airi is inspired by Miu, who can still smile despite having to give Pannya up, to help the school merger succeed, and organizes a student rally for the cause. Miu tries to be overly happy towards Pannya, but breaks down in the club room and cries on Shingo's shoulder. After talking with her mother, Miu finally resolves to let Pannya go back to its family. The club members go to the forest clearing where Miu met Pannya and it is reunited with its family after the club members say goodbye. Time passes, and in the spring the school merger has been completed. After Miu graduated, Sana becomes the club president.
