I guess fraudkuna is out of card now.
Interestingly with how this has been going I guess he could have killed Gojo without potential man's corpse.
Then again if potential man is still part of good guys, they could have sent Gojo with Makora (and I'll call it Makora because that's how it's pronounced in the anime) vs Sukuna.
Now how would Sukuna off Gojo without potential man?
Basically battle of domains, both are in burnout and Sukuna send the fire arrow and GG.
Now why go through all the trouble of using potential man's bad of mid?
from a writing perspective it shows full potential man vs the strongest,
shame about the ending though.
from in Universe perspective? I have no idea because outside of showing the bottom of Kuna's bag and he doesn't like that, it feels like it's not worth it at all.
Combat would have ended at chapter 225 after the 1st domain clash and the fraud would still have his domain and would be in a such a better position to get through the conga line of heroes tryingt to kill him.
So in short it's a pretty shoddily written story.
If Dragon Ball was airing today, people would be dumbfounded at the stupidity of the plot post Frieza arc.
Just enjoy the pictures, the writing is on the level of the industry, which is subterranean.
I mean have you seen how the Buu Saga was received?
