The 27th highest ranking earl of hell named after the demon of the same name. Ronove serves as Beatrice's (and later, Battler's) butler and head furniture. He often serves black tea and cookies to Beatrice and her guests. Nonchalant, he often bears a mysterious smile that is hard to interpret, even for his master. Even though he is bound by contract with Beatrice, he does not hesitate to state facts to tease her. He shares a link with Genji Ronoue, similar to the one held by Virgilia and Chiyo Kumasawa. In Alliance of the Golden Witch, he engages Jessica in combat, where he utilizes barriers for both offense and defense, generating strong ones to both deflect attacks and launch enemies backwards. He can also use a special barrier that returns damage back to the attacker.
