Prince Romeo, a human prince candidate within the Jewelpet universe, balances rivalry with camaraderie among his peers. His polished appearance features short blonde hair, turquoise eyes, and a refined wardrobe: a beige shirt paired with a dark green bow, a tan vest adorned with golden buttons, black dress pants, and loafers. Though gentle and modest, his competitive fire ignites around princes like Cayenne and Miura, culminating in a physical clash with the latter that results in temporary confinement—a mark of his passionate drive.

Tasked with princely duties, Romeo navigates etiquette evaluations, theatrical performances (including a rendition of *Romeo and Juliet*), and challenges ranging from stargazing to crafting mushroom hotpot. He proves adept, excelling in culinary trials with his signature mushroom nabe and forming strategic alliances with candidates like Momona, Mizuki, and Elena. A rejected confession to Momona steers his attention toward new ambitions, subtly reshaping his path.

His journey traces gradual growth: initial rivalry with Miura over Momona softens into a connection with Elena, whose calm guidance complements his evolving maturity. Together, they tackle tasks emphasizing cherished bonds, showcasing his collaborative spirit. Romeo’s resilience shines through overcoming Luea’s magical manipulation and aiding allies like Momona and Lillian during pivotal quests, underscoring his loyalty.

Named after the Alfa Romeo automotive brand—a theme shared among prince candidates—Romeo’s traits include a preference for meat, distinguishing him from peers. Early arcs frame him through competition and fleeting romance, while later narratives spotlight his supportive role and synergy with Elena, mirroring the broader tale’s emphasis on self-discovery and unity among rivals-turned-allies.
