Since Xie Wen and the cats had gone to Wano Country and wrecked Kaido's home base, Kaido naturally found everything about him irritating.
Not to mention...
His "son" had also been lured away by someone (a cat).
And what Kaido found most unacceptable was that Yamato was now dressed in women's clothing. He could even see a little light makeup on his "son's" face.
Didn't that mean that the daughter he had failed to teach no matter how hard he tried had been casually set straight by Xie Wen (the Palicoes)?
This made Kaido feel like a failure, yet he refused to admit his own failure.
So, the moment the irrelevant people left, Kaido eagerly jumped out, wanting to settle things with Xie Wen, the "culprit" in his eyes.
Of course, this was also partly because he wasn't confident he could handle Kaido Meow, who looked so much like him, and because he didn't want another horn blown off. Kaido could be very shrewd when he needed to be.
"...All right."
Unaware that he was actually taking some of the blame for Kaido Meow, Xie Wen only pondered briefly before agreeing outright.
Although sending Kaido Meow or Cat Princess was the safest choice, the point still stood: they were already fighting four against two. There really was no need to back down.
Besides, he had already been able to hold his own against an improved Mihawk with swordsmanship alone. As he was now, Xie Wen genuinely felt confident about taking on Kaido one-on-one without relying on the cats.
Still, that didn't stop him from teasing Kaido a little more beforehand...
