Ryomen Sukuna - "irmão"

Yuji is a muscular teenager with large light brown eyes and spiky black and pink hair. After eating the finger and consequently becoming a host for Sukuna, he receives a second pair of eyes that only open when Sukuna controls the body. Sukuna also has two lines on both wrists, arms, circles on both shoulders with a dot on each, two segmented curved lines on his chest, and two lines on his stomach while possessing Yuji.

Sukuna is a special grade cursed spirit. As the most powerful cursed spirit in the entire series, Sukuna possesses a vast amount of cursed energy. Sukuna's presence was felt throughout Shibuya as soon as he was awakened. His cursed energy is similar to Satoru Gojo in its immensity, but different in its oppressively evil nature. He soon overpowered and defeated Jogo, the most powerful cursed spirit in Mahito's group. Even Gojo acknowledged Sukuna's strength, stating that fighting him would be difficult. In each appearance, Sukuna has proven that he is by far the strongest cursed spirit of all time. He seriously injured Mahito when he got angry, defeated Jogo without much trouble, defeated Mahoraga, something that no user of the Ten Shadows Technique and even a member of the Gojo Family with the Six Eyes has done. His strength is so great that Mahito and Jogo were convinced that Sukuna's revival could guarantee his success. Sukuna's strength is only rivaled by other special notes like Yuta Okkotsu and Satoru Gojo.
