he takes on the appearance of his former host: Yuji Itadori, but with pink spiked hair slightly pushed upfront and with tattoos/lines on his forehead, nose, cheeks, upper body, and abdomen. He also has a second pair of eyes underneath his normal eyes, which are usually closed. Sukuna is selfish, cold-hearted, immoral, and exceptionally sadistic. Though his only exception is his best friend, Yuni, whom he loves unconditional but doesn't really show it.
