He perceives himself as weak, worthless, and not "good enough." As the "baby of the group," he often falls back on others to take care of him but feels guilty for this as he does not believe he does anything for his friends in return. SUNNY appears to struggle with issues of self-confidence and self-worth. HERO also states that SUNNY has a great memory. BASIL describes SUNNY as a "really good listener" who does not mind listening to him vent. However, despite not expressing it as clearly as the others, he still appears to care deeply for his friends, as his most treasured memories in MEMORY LANE and the LOST LIBRARY are of his time spent with them.

He rarely speaks and does not like to smile. Throughout both his childhood and the game's events, SUNNY is extremely shy and quiet. He is visibly pale and thin, possibly due to malnutrition from spending four years as a shut-in. He wears beige shorts, white socks, and black shoes. In the present, he wears a white-collared shirt with a blue vest over it.

He also has arched eyebrows and eyes with the same shade of black, in contrast with his paler skin. He has straight, black, ear-long hair with a fringe that slightly covers his eyes.
