Arriving at Japari Park under Mirai's guidance, Towa meets Serval, an Animal Girl of Serval Cat, and the mysterious fake Serval.

Towa and Mirai, who are now working with Serval, talk about the amulet Towa has on the way. Meanwhile, Caracal is attacked by a fake Serval.

When Serval comes face to face with her friend Caracal, she finds that she is angry with her. Serval understands that it was caused by the fake Serval, but Caracal's misunderstanding is not easily cleared up. But then the fake Serval appears and Caracal's misunderstanding is quickly cleared up.

With the addition of Caracal, Serval's group came to the An'in Region. There, the group heard an unbelievable singing voice and met Crested Ibis, the source of the song. She, too, was troubled by her own singing voice, so the group went to see an animal girl called Wise.

With the addition of Crested Ibis, Serval and the group meet two owl animal girls who are called wise. The girls told Crested Ibis that the sap of the copaiba tree was effective in helping Crested Ibis sing.
