Suguru is a tall, muscular man with shoulder-length black hair and thin black eyes. He despises non-sorcerers, referring to them as "monkeys", and believes that sorcerers are superior. He uses fake personas to lure in vulnerable people who are cursed. Suguru has a wide collection of cursed spirits and is a highly capable close-quarters fighter. He is one of only five special-grade sorcerers and is considered the worst of all curse users due to the danger he poses to humanity.
