Su is an intellectual and compassionate man, yet deeply restrained in expressing emotion. As a doctor, he dedicates himself to the pursuit of medical advancements, seeking ways to treat and understand Honkai infections. His compassion for others is evident in his unwavering commitment to his patients and comrades, yet he distances himself emotionally—whether as a personal philosophy or as a necessary shield against the weight of inevitable loss. Fuchsia eyes, light gray hair.
