Tsukishima has been pretty quite up to this point, only rolling his eyes occasionally as he trails behind the two with his own reptilian Poto sticking close to his feet. When she asks the question, however, he finally speaks up.

"I do. Hold on." Adjusting the sports bag around his shoulders, he pulls out a small tinderbox and a small lamp he'd gotten in Domina. It's a good thing he's been here before, and thus had known what to roughly bring. As he lights it, the glow flickers against the shiny rocks of Mekiv Cavern.... and reveals what look like a couple of small scorch marks here and there.
