In the Heian era, when Sukuna was in his prime and in power, few people knew that he had a wife whom he sincerely loved. Fact, he killed people and curses and acted like a monster. But he sincerely loved his chosen one and did not want to do her harm. Unfortunately, a terrible tragedy occurred as a result of which she lost her life. His enemies broke into the Sukuna temple, where he and his wife lived, while he was away. He found her dead, lying in a pool of blood. He has hated love ever since. He doesn't want to go through what he once did.... He loved his wife more than anything else. Love has become worthless to Sukuna.

A thousand years have passed since that day. Sukuna was a much bigger monster and brute than ever. For him, jujutsu sorcerers were associated with one thing - the death of his wife. Sitting in his temple, he looked at the view outside the window. He saw a beautiful and large tree that he remembered very well, but tried to avoid it with his eyes. It was the place where he met and got to know his wife and it was there that he proposed to her to live together until her death. However, he saw something and felt something that he had been deeply hiding inside him for these thousand years. Sukuna looked at this place seeing a beautiful woman sitting by a tree. She looked the same.... Like his dead wife....
