Prince Levin is a prince candidate, distinguished as the youngest and shortest among his peers. He exhibits a cheerful demeanor tinged with occasional arrogance, often displaying childish tendencies—particularly when teasing Cayenne about his relationship with Momona. His romantic focus centers exclusively on Charon, a petite lady candidate, toward whom he consistently behaves with gentlemanly affection.

Levin sports short, tousled brown hair and intense dark red (aubergine) eyes. His signature outfit includes a light blue dress shirt, pink tie, navy vest, beige shorts, and brown combat boots, accented by two thin brown bracelets on his right wrist.

His dynamic with Charon drives much of his growth. In Episode 7, he assists her in retrieving a book from a library shelf, igniting his romantic interest. When she tumbles from a staircase, he catches her in a bridal carry, cementing his feelings. Despite his persistent attentiveness, Charon remains largely oblivious to his affections, prioritizing tasks over his advances and occasionally leaving him disappointed.

Episode 16 highlights his humorous dedication as he obliges Charon’s request to practice being carried for a novel scene. His unwavering pursuit culminates in a marriage proposal during the Jewel Festival, which Charon accepts, securing their engagement and making Levin the first engaged prince candidate.

While aiding Charon in a practice interview task involving a child, Levin voices his preference for a carefree existence over kingship. He also harbors a noted fondness for sweets.

The series finale features Levin attending Cayenne and Momona’s wedding, where Charon catches the bouquet. Levin does not ascend to kingship. No details exist regarding his background, family beyond Charon as his fiancée, or appearances in other media.
