Vino von Lomzard (ヴィーノ・フォン・ロンザード) is a Duke, a high-ranking noble from the militaristic nation of Milidonia. He possesses blonde hair and striking violet eyes. His defining trait is a consistently flirtatious demeanor, expressed through theatrical romantic gestures and the frequent use of pet names like "Little Flower." This womanizing personality leads him to adopt poses and deliver lines reminiscent of stereotypical romantic archetypes, though his advances often meet blunt rejection or annoyance, particularly from Princess Ani of Inaco.

Beneath this frivolous exterior lies unwavering loyalty to Prince Narek of Milidonia. He demonstrates this allegiance by refusing to cooperate with factions seeking to install him as king instead of Narek. Vino is actively involved in Milidonia's political maneuvers, including schemes related to invasions and internal power struggles. He appears during critical moments, such as the finale's conflict, supporting the main characters against threats to Milidonia and its allies. His role extends beyond comic relief, displaying an awareness of political undercurrents. Specific details about his background, motivations, or internal development remain unexplored, as does his existence in other media beyond the anime.
