So given how Gege has drawn a lot from Heian era, and a lot of Buddhism esque, like how we see with Gojo and Sukuna both being “honored ones”, I think Yuji is gonna have a strong ability where he’s the honored on of the black sparks, but that’s just a side thing I think. I think his main ability is gonna have something to do with Karma. He’s suffered so much from the Shibuya incident, and it’s just piled on and on since sukuna took over megumis body. I think at some point yujis awakening will give some representation of Karma, being able to withstand any attack and reciprocate it 2fold due to divergent fist and black flash, channeling the CE Outout delivered to him through say Sukunas slash techniques. Idk just an idea that popped in to my head when rereading
