Comments of chapter undefined of Gojo Satoru- Adventure Through The Multiverse

Of course it's never mentioned, but you can still use feats for this. For example, we already have Kenjaku who is like, not even close to 15F Sukuna, let alone Gojo, who is able to somewhat react to the black hole in time, and even activate his technique in time despite how close he is. This would be already Massively hyper sonic at least. Then we have in the anime where Sukuna is literally out pacing and blitzing the explosions Jogo threw at him. To do so, you'd at least need to be Massively hyper sonic to do so casually and fast. Then we have instances where Toji can react and turn his head to the lightning Nue threw at him, moving faster than the lightning. That's pretty much massively hypersonic, and he's far below the likes of 15F Sukuna and Gojo. We also have a nearly dead, crippled Sukuna, dodging Electromagnetic waves at a very close distance, even being able to react to it. So yes, the god tiers, aka Gojo and Sukuna, are already that high. The likes of Kenjaku and Toji, although far below, are at the very least way above hypersonic, entering massively hypersonic.
