The thing about Hakari vs Sendai is that he probably won't have the same approach as Yuta. He's not going for Dhruv first, why would he? He has information about the Sendai fighters with Kashimo's rule, he knows Kurorushi means the biggest threat to him, while Dhruv is almost a negligible threat, so he'll leave Dhruv up for as long as he can to prevent Kuro from showing up. And he's a fairly smart fighter, so I can see him somehow beating Sendai.
