Before eating Sukuna's finger, and before being able to use cursed energy,
Yuji Itadori is shown to have "superhuman strength" and "superhuman physical
abilities", making him able to throw a lead ball with enough force to to bend
a soccer goalpost. He's also said to be able to run 50 meters in 3 seconds,
which would be a world record if true. What's the reason for this?
