Jūgo is a very tall, muscular young man who has spiky orange hair, red-orange eyes, and a usually calm disposition. However, when affected by his murderous side, his skin turns dark, his irides become a pale yellow colour while his sclerae turn black, and he grows various weapons and appendages to suit his battle combat situation, as well as having a deranged look. Jūgo has a bracket-shaped symbol on his left palm.
