His technique looks like a low powered version of the Kaleidoscope mixed with the denial of nothingness from Fate. Exceptional descriptions though, probably the best JJK story I have read so far.
There is something I want add if gojo can overlap his blue to his fists can he do the same with red which could grant him explosive power to his punches that it could rip through flesh kinda like yuki
Amazing chap, love the technique however wont he now be to overpowered or will there be some sort of powerful alien like monsters that he will fight. Since Sukuna and Gojo wont be able to fight him now.
