So u think kashimo attack will be more and more powerful than gojo purple 200% and for some reason he can't use rct?
We have seen characters who are way weaker than gojo still have stronger attacks
For example : yorozu and yuki
Kashimo most likely has a binding view with his technique , that he can only use it once once sukuna and that’s why the Attack will have way way stronger ap , due to the binding vow , it can be some type of attack which sukuna can’t heal or kashimo’s CT can just be soul based .
There are a lot of options but kashimo will def fuck sukuna up with his ct bomb
