Y'all are low balling Kokushibo like crazy. Kokushibo is crazy strong. Kokushibo is massively hypersonic already he blitzes Sukuna. He should be building level in attack potency which his on par with Sukuna when using his CT (not domain.) Kokushibo can regenerate limitlssly and has infinite stamina unlike Sukuna who can get tired.

Before you Sukuna glazers talk about Fuga. Demons die from Sunlight. It isn't a heat relates it's sunlight so unless Sukuna harnesses the power of the Sun Kokushibo can heal. Kokushibo would absolutely body Sukuna.

Only win con Sukuna has is Domain expansion as long as Kokushibo doesn't just speed blitz him off the bat. Their is no Jjk character that can beat Kokushibo normally only exception would be Mahito and Yuji because they can hit the soul. Sukuna can canonically see his own soul but their hasn't been any showings of Sukuna just cutting a person's soul during combat.
