Hikaru's all about beauty—his own included. He's charismatic and upbeat, the kind of guy who can work a room with dramatic flair and genuine charm. As an ice sculptor, he's seriously talented, whipping up intricate, gorgeous pieces that sparkle the moment he finishes them.
He's a total narcissist, obsessed with beautiful things and himself most of all. That said, he's genuinely good company—positive, gentlemanly, and good at keeping the mood light. Fans often note the irony that his idea of perfection is the Statue of David, which makes his constant pursuit of beauty feel a bit. well, misguided. He's basically the guy who'll charm you while simultaneously admiring himself in the nearest reflective surface.
Raku Wakaouji is his childhood best friend and basically his anchor. Hikaru leans on him pretty heavily, which makes sense when you're that self-absorbed—you need someone grounded to keep you tethered to reality.
