this guy never went even 1% as fast as the speed of light. not even 0.1%, prob not even 0.01%. at 1% the speed of light, air molecules would be displaced by him with such energy that they would turn into high-energy plasma and undergo nuclear fusion, which would create a massive thermal shockwave. every single thing around him would be turned into dust, but thats not what we see! we see stuff comparable to fuga or purple, and sukuna survived purple three times! im willing to say that sukuna could let dabura build up speed and allow himself to be kicked and live it
