Vermilio and Helck find themselves on a remote island created by a man-made space teleportation gate. After Helck rescues Vermilio from a precarious situation, Vermilio struggles with his feelings, wondering whether Helck is a friend or foe. As they explore the island, they encounter a stern-looking man who appears to be the village chief. At first, he seems hostile, but it soon becomes clear that he was only playing a prank on them. The villagers warmly welcome the duo and hold a feast in their honor.

During the feast, the chief mentions a great witch who lives on a mountain. This witch, revered by the villagers, possesses vast knowledge and might be able to help Vermilio and Helck find their way back to the mainland. However, the mountain is protected by a magical barrier that prevents anyone from reaching the witch. The chief assures them that the witch will come down in a day or two.

While they wait, Vermilio and Helck talk about their pasts and their motivations. Helck reveals his determination to stand against the winged knights, even if it means fighting former comrades. He believes that the awakened humans, under the influence of the human king, pose a threat to the world.

Suddenly, a group of winged knights attacks the island. The situation seems dire until reinforcements arrive, led by Isty, a familiar face to Vermilio. Isty introduces them to Lord Azudra, one of the four elite lords of the demon realm. Azudra wields immense power, which he demonstrates by single-handedly defeating a large group of winged knights by controlling nature itself.

Azudra attempts to reason with the humans, advocating for coexistence and reminding them of a time when humans and demons lived in harmony. However, the winged knights, driven by their loyalty to the human king and their newfound power, refuse to listen. Azudra, resolved to protect his people, prepares for the inevitable conflict.
