Jujutsu Kaisen: The Radiance of Avalon

After an accident outside the bounds of fate, Xu Tian was forced to live a second life in Jujutsu Kaisen. As compensation from the world's will, he became Shoko Ieiri's younger brother, Ieiri Yan.

Armed with a holy sword, carrying a sacred scabbard, and possessing an almost limitless supply of cursed energy, can Ieiri Yan break the “curse of the strongest”?

“Sorry, Gojo. I've taken the title of the strongest.”

(The early chapters have more daily-life scenes and some setup. I'm a new author, so please feel free to point out anything that needs improvement.)
