Twisting back to look where they’ve been going, Tsukishima has to admit that the dragon has a point, one that makes him grin dryly. It looks like, through complete coincidence, he managed to get the perfect partner for this little journey.

“I guess I can’t complain about that… They’re a lot more reliable than bread crumbs.” A pause as he considers something. “Although I guess you won’t get that reference..” Shaking his head, he adjusts himself again and watches the gloom up ahead. Now and then, he can hear the click hard crab legs against stone off in the distance, echoing from the cavern walls, and sometimes the flap of wings-

Actually, those are definitely not off in the distance, as something about as big as his torso and a dark purple suddenly flaps down from the large ceilings and starts to shriek at the pair of them, soon followed by a few more. Grimacing as he clasps his hands over his ears, Tsukishima glares up at the creatures.
So. Bats. It looks like that’s unfortunately a thing.
