Miya Chinen, a 13-year-old middle school student and Japanese national skateboarding prospect, balances sharp technical skill with a style infused by gaming culture. His black hair, styled with defiant upward strands, frames aquamarine eyes, while cat-eared hoodies and animated tails punctuate his outfits. His custom skateboard, marked by a bold purple "X," feline designs, and the word "Game," mirrors this aesthetic blend. Beneath his confident exterior lies a guarded psyche shaped by childhood isolation. Early skateboarding friendships dissolved as his rapid skill growth eclipsed peers, culminating in a friend’s cutting remark comparing others to "slimes" unworthy of heroes. Miya internalized this hierarchy, adopting a self-protective arrogance that masks fear of abandonment. He deflects vulnerability by mocking less skilled skaters like Reki Kyan, weaponizing the term "slime" to maintain emotional distance. A pivotal loss to Langa Hasegawa fractures his defenses. Tearfully confessing his loneliness to Reki, Miya tentatively accepts Reki’s steadfast promise of friendship, sparking gradual trust. This bond extends to Langa and Shadow, evolving into a brotherly camaraderie that softens his aloofness. Miya’s skating dominance—honed through childhood drills and innate talent—includes mastering an ollie in two weeks and executing precise tricks like board handstands. His regimented lifestyle balances school, skate training, and gaming, with strict dietary controls and athletic conditioning underscoring his discipline. The *SK8 the Infinity Extra Part* OVA captures his subtle integration into the group during a rain-soaked day. Forced indoors, Miya engages in karuta and convenience-store antics with Reki and Langa, revealing flashes of relaxed humor and collaborative spirit. Personal quirks include a preference for salt-grilled pacific saury, RPG enthusiasm, and a Pisces zodiac sign. He avoids spicy foods and views romance pragmatically, prioritizing shared interests like pets over current dating pursuits. Design elements—embroidered socks, a dynamic tail accessory mirroring his moods, and board graphics inspired by freestyle skating’s agility—visually echo his competitive drive and playful identity.
