When Situational Slash vs Kashimo?
What works against Lightning style?
Wood and earth style jutsu?
Expect something like that.
Or maybe, Sukuna's cursed tool will overpower Kashimo's lightning
Anyway, I expect the tool to give Sukuna some resistance to lightning.
Btw, how a cursed tool is able to use elemental power? It is the first of its kind so far, right?
