Sero Hanta is 16 years old and stands about 5'9" with a lean, athletic build. His dark, messy hair has a natural wave to it, often left unstyled, and his warm, brown eyes have a playful spark. His face is defined but not overly sharp, with soft features like a slightly crooked nose and a faint, uneven jawline. A few freckles dot his cheeks, and his arms are toned from constant use of his quirk, which leaves small, barely noticeable scars and indents from the tape dispensers on his elbows.
