The Golden Age of Jujutsu
The Golden Age of Jujutsu was 1,000 years ago, during the Heian era. This is when Ryomen Sukuna was still living as a curse.
Many other powerful sorcerers and curse users thrived, fought, and killed each other. A twisted curse-user known as Kenjaku also lived, and he becomes
a major antagonist during the story. Kenjaku is over 1,000 years old, and one of the strongest Curse-Users.
