In the final episode of the season, Satou and their companions find themselves in the ruins of Idanokan, amidst a confrontation between the imperial troops and the army of the Abyss King. The Abyss King proves invulnerable to attacks until Satou, with the support of their allies, manages to temporarily disperse the forces of the Abyss King with a united strike from their rings.

Nevertheless, the Abyss King remains undefeated and attacks Satou, who is now powerless. As the situation escalates, Satou's wives, especially Granart and Amber, defend them. When the Abyss King summons additional troops, they face an overwhelming chance. Exhausted, Satou loses consciousness.

During their unconsciousness, Satou experiences flashbacks and is rescued from the danger posed by the Abyss King by Alabaster and Smaragdi aboard a giant flying bird. Alabaster acknowledges Satou's efforts, which led to the temporary retreat of the Abyss King and their army.

After their return to Hime's kingdom, Alabaster reveals the unique nature of the Abyss King's dark rings and suggests that Satou and their wives should strengthen their power through deeper unity. This advice is visually emphasized in the episode's final scene, where the women are seen in their underwear, hinting that their relationship should be strengthened in the future.

Furthermore, the appearance of Hime's sister Morion Ravri Nokanakita introduces a new magical ally and hints at the continuation of their journey in the next season. The episode ends, paving the way for further developments and challenges for Satou and their companions.
