Itadori yuji goes back in time to where it all started, and acts like his past self to not arouse suspicion or worry. He gets trained by sukuna but slowly get corrupted by the curse energy's malice. He secretly is the new king of curse's and can control the other curse's but keeps everything a secret. it all becomes a fun little game to him...but who will win? I don't plan on having any ships in this fanfic so I just want to clarify the sukuna and itadori have a sudent/sensei and rivalry relationship. I will tell you guys ahead of time if i change my mind and add a ship. I hope you all enjoy this fanfic! MelodieNox^w^
