Soarer emerges as a shrewdly strategic and methodically analytical prince, maintaining an unflappable composure complemented by scholarly dedication. He chronicles his observations in a well-worn notebook, his astute analyses frequently dismissed by peers—save for Mizuki, whose perceptiveness aligns with his own. Their rapport evolves following a botched parasol assignment in Episode 10, where Mizuki’s abrupt withdrawal from the test results in mutual failure. Rather than resent her choice, he responds with empathy, deepening their connection through collaborative resilience.

By Episode 12, he teams with Lilian for a childcare challenge, securing a successful outcome through meticulous planning. During subsequent Royal Palace interviews, he faces Cayenne and Romeo in competition, yet gracefully accepts Cayenne’s selection, prioritizing camaraderie over ambition. His nomenclature traces back to the Toyota Soarer luxury vehicle, while his disciplined intellect extends to swordplay mastery.

A poignant turning point arises when he presents Mizuki with a diamond ring as a Christmas farewell gift, subtly suggesting unspoken affection. Their evolving dynamic—marked by Mizuki’s spirited assertiveness against his measured intellect—cultivates a layered camaraderie. Despite his unshakeable poise, a concealed fear of haunted houses reveals unexpected vulnerability, rounding out his composed yet multifaceted persona.
