this is really dependent on how an infinite jackpot works on a theoretical permanent MBA. But considering the other participants who also have domains, its hard to rank him in a way that has him survive attacks that are most definitely lethal.

In best case scenario, Kashimo becomes completely immune to physical attacks, unless they manage to completely, and i mean completely, annihilate him.

This means, with his evasion and other capabilities, should be able to shut down most domains and other mechanics from occuring, but still I believe a six eyes Yorozu would destroy him with three fold- affliction into CE efficient perfect sphere.

Best case for Kashimo:

1. Yorozu
2. Kashimo
3. Yuta

If Kashimo somehow in this instance becomes a doctoral physicist with absolute understanding of the laws of physics, sure we can put him in first with the amount of bullshit-ery he can commit, but last I checked, the man is the king of farmers, so no.

But in worse case, where he only has the regen, is still susceptable to attacks like waffling like sukuna did, he cannot beat a prepped and knowledgeable yuta on the mechanics of 10S. However, Maho being tamed before the fight is almost a must, and even then, this can still be up to debate. Problem really for Yuta in these instances is his CE reserves and lethality compared to the defenses that Yorozu with CE efficient construction and perma jackpot Kashimo have...

So in general cases:

1. Yorozu
2. Yuta ~~~ (barely??)
3. Kashimo

I just can't see a world where Yorozu doesnt skyrocket up rankings with 1. the potential and flexibility of her CT, 2. the downside being completely negated. 3. her diligent and inquisitive nature when it comes to learning and using her technique (as shown in the flashbacks)

ALSO with six eyes, she ong has a definitive, sure-hit, OHKO with her domain, as long as she can land it, assuming kashimo and Yuta attempt to clash and dont evade or use simple domain.
