He has no doubt that he can catch her -- though he's so surprised and delighted by her display that he's silent for a long moment, even as he finally moves to pull himself, dripping and shivering, onto the floating layer of ice.

"Aw, shit," he says. The powdery snow is just as bad as the water was, making his ability to use his chakra to stick to any surface pretty much moot. He'll just have to get his muscles themselves accustomed to handling his body on the ice.

The air above is densely foggy from the evaporate now, and still dotted with snow. Not penetrable for Naruto's senses normally, but he knows how he can even the scales a little. He pulls chakra not from himself, but from Kurama; not enough to cloak him entirely, but enough to turn his irises the rosy pink of their combined eyes, pupils thin slits. He doesn't need the extra chakra pool to draw from, but he does need the benefit of Kurama's superior senses.

In a few breaths, the thin, whispery cracks of the ice over the water are clear, her breathing and heartbeat there for him to stalk with his ears.

He still struggles to move after her without slipping, and after ending up on his ass for his protracted third time, Kurama finally speaks up again to his advantage. Claws, he counsels, and it takes a minute for Naruto to get the hang of actually putting that into play, but once he does, on four legs is the way to go, the ice simpler to navigate with sharp grips and a low center of gravity.

"You are so screwed," Naruto announces, followed by an ill-advised bark of obnoxious laughter.
