It’s definitely hard to ignore the strange shift of something not organic beneath his body, all the more telltale whenever he has to grab on tighter or straighten his position and there’s something sturdier than bone beneath his fingertips. Less flexible.

It raises up a lot of questions, but Tsukishima tries to keep them to himself for the time being. It’s something to ask later, when there aren’t more important things to focus on. For the rest of the afternoon, he focuses on working with Skyfire to find the exact right seating arrangement for both of them, pointing out if something doesn’t feel right or ways for either of them to improve. Only when the two of them find something that works does he call it quits for the day. So by the time the next day comes, he’s…. Somewhat confident that they’ll be alright.

His body will be sore if he stays on Skyfire bareback for too long, he’s pretty sure, so it’s better to stretch his legs out when he can. A good thing that it doesn’t really take that long before the cavern opening is looming before them, and he adjusts his sports bag that he’d brought along. “I’m pretty sure this is the place.”
