manga style, Kai Arlin is a lean and agile 16-year-old with messy dark brown hair often falling into his sharp green eyes, one of which is a distinctive glass prosthetic with a faint glow. He wears rugged, practical clothing patched together from various sources, including a worn jacket, sturdy boots, and fingerless gloves. A tool belt filled with makeshift tools and gadgets is slung across his waist, reflecting his resourcefulness and readiness for scavenging or repair work.
