Charon, also called Karon, hails from Jewel Land as a Queen Candidate and Petit Lady determined to become the next Lady Jewel. Partnered with the Jewelpet Sapphie, she balances her ambitions with the demands of royal refinement. Her mocha-brown hair flows in twin braids fastened by star-shaped clips, while her casual ensemble—a black turtleneck beneath a white overshirt, an ochre-accented skirt, thigh-high socks, and brown boots—reflects her understated charm. Transformed into her lady form, her hair tumbles in loose waves adorned with the same star clips, complemented by red rectangular glasses.

Kind-hearted yet introverted, Charon often immerses herself in tasks or literary pursuits, her dream of becoming a novelist sometimes overshadowing social nuances. Initially oblivious to Levin’s affections, their bond deepens through collaborative efforts, his support during her homesickness, and his guidance in her writing. Pivotal moments—protective acts in the library, shared vulnerabilities, and a fireworks-lit proposal—culminate in her accepting his love, marking her emotional growth.

Raised with an older sister, Ellis, and inspired by Sapphie’s encouragement, Charon thrives alongside friends Momona and Mizuki, her reserved nature balancing Mizuki’s tomboyish energy and Momona’s earnest drive. Despite shyness, she displays quiet resilience, challenging deceit to uphold honesty and enduring the rigors of royal life. Her journey from naivety to self-awareness unfolds through joint trials, mutual trust, and Levin’s steadfast devotion, culminating in a matured embrace of vulnerability as she steps into both romance and her destined role.
