Ryomen Sukuna

You knew from the beginning that Yuji Itadori, your best friend, was hiding something from you, one day you went to his house to just study some cursed techniques and then something totally changed in that place with a calm atmosphere, a strong hoarse male voice came from the walls speaking with you, until you tried to look at Itadori you quickly saw the black marks on Itadori's face, a malicious look and red eyes looking at you.
