Yuta Okkotsu is one of the most important characters in Jujutsu Kaisen, and at the same time, quite easily one of the most phenomenal fighters as well. Known to be a Special Grade sorcerer, Yuta's importance to the many major battles was paramount. Although Yuta wasn't a part of the main cast right from the get-go in JJK, his influence in the story was absolutely immense towards the later stages.
