Though he serves as Battler's opponent for some parts, he is unable to make any moves without approval from Beatrice herself. Later in the story, Ronove becomes Eva-Beatrice's furniture after Eva Ushiromiya solves the epitath. He mainly only appears to inform her of Beato's wishes and to help her to become a great witch. When Kanon and Jessica are escaping he spots them and lets them escape while Eva-Beatrice is distracted with playing with Terumasa Nanjo's corpse.
Alliance of the Golden Witch
Ronove and Gaap appear before Jessica and George Ushiromiya to test them, asking them whoever they would like to be sacrificed next - themselves, their true loves, or everyone else. Jessica says she would sacrifice herself for Kanon's sake because she wants him to be Kanon, and George chooses everyone else because he is willing to go so far for Shannon to be accepted. The two then defiantly engage their respective demons in combat because they are unwilling to leave the prisoners in the dungeon of Kuwadorian. The two are about to land the final blows on their opponents when Gaap creates a gap that teleports the two near each other, just as their attacks connect with one another, killing each other. Ronove temporarily revives Jessica as a favor, allowing her to call Battler at the guesthouse to warn him of their enemies' magic.
- Ronove is based off the Marquis and Great Earl of Hell who teaches Rhetoric languages. He also gives loyal servants a favor of friends and foes.
