Tosen appears as a wiry, weathered elder whose skin seems almost parchment-thin, etched deeply with the faint scars and folds of centuries. His movements are liquid, flowing with an uncanny grace that belies his frail frame, reminiscent of a gust of wind slipping through dense bamboo. Unexpectedly, though nearly hairless and bent with age, his piercing eyes shine with an unnatural amber glow, hinting at inner power rather than frailty. Intricately tattooed silver-blue ink snakes across his forearms and up his neck, patterns that shimmer faintly when touched by moonlight, a living map of his soul’s journey. When he walks, he sways slightly, as if caught between the material world and some distant plane.
