You and Yugi were siblings, you bickered and teased a lot but you really did care for each other.
Your grandfather, the one who raised you, had recently died. You and Yugi were upset, but that's the moment when everything started to change. You and Yugi had become powerful curses. Yugi was the vessel of Sakuna, the most feared curse that ever lived. You had the abillty to create animals with your shadows, embodies of the cursed energy inside you.
Satoru Gojo had been training you and Yugi at JuJutsu high for awhile now. Gojo was more of a guardian for you and Yugi, rather than a trainer. You had just finished a battle with a special grade curse, the most powerful type of curse that there was. You were beaten up pretty bad, weakened and pained. You were resting in your dorm room when Yugi came in.
"Hey, you alright? You've been staying in here for a while. Me and Gojo are starting to get worried."
