First Battle.Kūya sent Genjimaru's granddaughter, Sakuya to Hakuoro to tell him that she wants to meet with him. At first, she wanted to give her Sakuya, her close friend, to him as a sign of friendship between their country. But Hakuoro refused her offer because he didn't like to take Sakuya away from her. Then, Kūya told Hakuoro that she wanted to start a war with the countries that opposed them. Hakuoro told her if she and her country of Kunnekamun will be okay. Kūya told him that he shouldn’t underestimate her country because they have been given great power as a blessing from their god, Onvitaikayan. The next day, Kamyu sucked Arurū’s blood and went missing. Everyone went to look for her, even Arurū. Hakuoro found her but she didn’t want to come back because she thinks that Arurū don’t want to become friends with her anymore. She told Hakuoro that in their clan, she is the only one who has black wings and people told her that it is because she has a blood that has a close relation to their ancestors. Furthermore, she is treated differently in their clan and has no friends until she met Arurū and Yuzuha. Hakuoro told her that Arurū wouldn’t severe their friendship by just sucking her blood and he also told her how worried they are looking for her. When Arurū came, she told Kamyu that she forgives her and still wanted to be friends with her. Kamyu returned to the palace as tears of joy dropped on her cheeks knowing that everyone in the palace treat her as a friend. After a few days, they heard a report from their soldier that Kūya has waged war with Nosechesuka, one of the great three countries alongside Onkamiyamukai and Kunnekamun, and defeated them in just 3 days and still plans to defeat other countries that opposes her. Hakuoro went to meet Kūya again in order to dissuade her from waging war. Kūya, who just experience killing someone for the first time, told Hakuoro how she enjoyed it and does not want to stop.
