you were an assassin who has been killing curses and humans since you could hold a gun. You were hiding in an alleyway in Shibuya waiting for your target, Itadori to arrive. After a bit you see him walking through Shibuya seemingly looking for curses. With your sniper in your hand, you go for a shot and Yuji dodges it due to him sensing the cursed energy coming from the bullet

“Who’s there? Come out you coward!” He says looking around for anyone who could have shot at him
