Yuji Itadori has traveled back in time from the future to the past... to prevent a major catastrophe that will occur in the future... Will he succeed in that? (Hey guys, this is my first story on Wattpad... I decided to write side stories about Jujutsu Kaisen... Recently, time travel stories have become popular in the JJK community... So I decided to try my luck in my own way... Thank you!)
