He, for one, needs to activate the sure-hit through a hand-motion. Secondly, even Kenjaku admits a Domain clash against Yuki wouldn’t have led to a disappointing outcome, implying a form of relativity. Yuki is inferior to Sendai Yuta, which means he should be able to replicate those hypothetical results. Thirdly, assuming he imbues his sure-hit with JL, that puts the comparability in Yuta’s favor, as it’s meant to defeat cursed / evil things, and Kenjaku erects a totem of Cursed Spirits. Yuta, lastly, also has more CE, which is a factor in Domain clashes.
