At the end of the Night Walk of One Hundred Demons, the extremely evil curser Xia Youjie was killed by Gojo Satoru.
Gojo Satoru never thought that what he said would become a curse.
"How long have you been with me?"
He was silent for a while.
"It's very vague... Probably when you erected a monument for me?"
The black-haired man rubbed his chin, with a calm and indifferent smile on his face.
Said, "Satoru, you did not curse me at that time."
What happened?
It's just a promise that neither party paid attention to.
Intent: Years of change
