Sukuna

as soon as sukuna was freed from the fingers he goes to his domain and as he’s walking to his palace he sees someone in the distance of a field thinking there’s an intruder and he sees a person with a white haired monk with chin-length white hair, an irregular line of dark plum pink running horizontally across the back of their head but there head is down bowed to the ground so he can’t see there face and he approaches who are you?
