Hiromi Higa, alias "Shadow," navigates a dual life split between his daytime profession and nocturnal identity in Okinawa’s underground skateboarding scene. With a tanned, muscular frame, he stands 178 cm tall, weighing 73 kg, his appearance marked by a short orange mohawk and sharp dark gray eyes. By day, he works at Tulip flower shop, clad in a cream sweater, dark blue pants, and a brown apron, his pale green sneakers and rolled sleeves reflecting his practical, cheerful demeanor as he assists customers. As Shadow, he transforms into the flamboyant "anti-hero of 'S' races," sporting a theatrical ensemble: a sleeveless black jacket with white lapels, a metallic undershirt exposing an "SD" tattoo on his left bicep, spiked bracelets, and a purple-and-black cape. His face is painted stark white with green and purple streaks framing his eyes and mouth, paired with metal shin guards for gritty races. Beneath his contrasting exteriors, Hiromi’s personalities remain starkly divided. At Tulip, he radiates warmth and diligence, yet as Shadow, he deploys chaotic tactics like hurling miniature fireworks ("Haemanthus Bomb") or blinding rivals with a red laser ("Gladiolus Laser") during high-stakes competitions. Despite his aggressive antics, he avoids malice, channeling his rowdy energy into strategic gameplay. His duality extends to relationships. Initially perceived as an antagonist, he gradually mentors younger skaters like Reki Kyan and Langa Hasegawa, offering rides, meals, and protective counsel to Miya Chinen. This mentorship mirrors his own balancing act between identities, paralleling figures like Adam in the "S" circuit. Hiromi’s compartmentalization of his flower-shop kindness and Shadow’s theatrics underscores his adaptability, weaving complexity into his daily grind and skateboarding passion. The juxtaposition of his nurturing and competitive sides reveals a layered individual thriving in two worlds, each demanding distinct facets of his identity.
