Suguru is a tall, slim, and muscular man with long black hair partially tied up in a man bun while the rest drapes down his back. He has thin black eyes and bangs that occasionally cover the left eye. His earlobes are large enough to fit fairly large circular earrings. In 2006, Suguru's hair was much shorter as a student, most of it tied up but his bangs were still as prominent. After August 2007 when Suguru became a curse user, his hair began to grow longer and reflect the length it is in 2017.
