While treating Leopard as she comes down with a fever, Galina tells her about Allouette's father, Gorozo, who entrusted him with Allouette's protection, while Leopard seems to develop feelings for him. Meanwhile, Allouette comes across Kussie, a monster from Lake Kussharo-Dessharo whose mother was captured by Goro and Yatter Soldiers, who wanted to use the nearby land for a factory. Despite her fever, Leopard decides to help Kussie reunite with his mother and the group head to Lake Kussharo-Dessharo, where Kussie's mother is being held captive. Just as Goro corners them, he is distracted by the lavender scent coming off of Allouette, giving Kussie's mother the chance to break free and counterattack, allowing mother and child to be reunited.
