Theo is a tall and athletic man with an upright posture that reflects strength and agility. His eyes are dark grey, deep and sharp like the shadows of night, always hinting at thoughts that are hard to guess. His hair is jet black, slightly messy, but it adds to his mysterious appeal.

His face is handsome with sharp features—a strong jawline, a straight nose, and thin lips that rarely smile. There's a cold aura surrounding him, as if he's used to living in silence, yet there's something so captivating about the way he carries himself.

Theo almost always wears black clothes, often with a hoodie that slightly covers his face. His clothes are simple but classy, with a long jacket that wraps around his body and minimal accessories like a small earring in his ear. Although he prefers to be alone, a single glance from him is enough to make others think twice before approaching.
