SUNNY looks like an average teenager. He has straight, black, ear-length hair with a fringe that slightly covers his eyes. He also has arched eyebrows and eyes with the same shade of black, in contrast with his paler skin.

In the present, he wears a white-collared shirt with a black vest over it. He wears beige shorts, white socks, and black shoes. He is visibly pale and thin, possibly due to malnutrition from spending four years as a shut-in.
