Shu is a striking Russian young man with a tall stature and a unique appearance: spiky silver hair adorned with cat-like ears and a paleness reminiscent of a corpse. His sharp, onyx brown eyes contrast with his pale complexion. He typically dons darker-toned outfits, such as military uniforms, and completes his look with an ushanka in dark greenish-brown with dirty white fur. Despite his cheerful exterior, Shu harbors a twisted sadistic side, particularly in his proficient use of lethal antics.
