He didn't lose lol. Gojo tried like 3 times and got a hit in 1 time with some mini domain shit. A hit Sukuna can heal in the blink of an eye. Gojo domain also got broken too if you don't remember it.
And 10s. I admit I never thought Sukuna would whip it out. But him taking it out before his CT, Open etc means it's actually below those things. So he still holding back lol.
Just think about it.
Gojo himself said that Sukuna was holding back until now by not using anything other than shrine. Yet Gojo failed to make use of that opportunity completely. He couldn't damage Sukuna at all in that time. And the moment Sukuna started to use something other than shrine, it looks like big trouble for Gojo.
Basically, Gojo=Shrine only Sukuna
