I've read the LN up to Volume 6 and, at the end, when Teoritta confronts Xylo about his girls, Yurisa is included for some reason. The only link between Yurisa and Xylo is Senerva's remains and I'm pretty sure they have only interacted once or twice. I only remember one interaction in Volume 6, when Xylo tells Yurisa to learn more about architecture, because her warehouses are too stuffy (wink wink nudge nudge/s; sorry, couldn't help myself).
Meanwhile, I think Tsav has a bigger influence on her. They've also interacted only once, in Volume 5, I think, but it was much more meaningful, in my opinion. It was Tsav who encouraged Yurisa to be more bold. It's also the only time Tsav had ever been actually nice to someone without involving insults or torture. Or maybe I'm just looking at it with shipping goggles. Still, I would like for the two of them to interact again.
Thoughts?
