Iori Okkotsu

Iori Okkotsu is the son of Yuta Okkotsu and Maki Zenin, and the father of Yuka and Tsurugi. He mysteriously disappeared when Yuka was born, reportedly because he felt his role — producing a child with a cursed technique — was complete. Neither his parents nor his wife would speak of him, leaving Tsurugi to piece together information through discreet inquiries within the Gojo clan. A flashback reveals he had a conversation with Yuji Itadori at some unknown point before his disappearance, though the substance of that conversation was never disclosed. Iori is one of Modulo's most deliberately withheld figures — a character whose absence shapes two other characters more than his presence ever could. His disappearance is treated neither as heroic nor villainous, but as something stranger and harder to categorize: a man who decided what he was for and then left when it was done.
