Katara smiled when she heard the spell: she was sure she'd heard Nanoha use it before, and it was no less impressive when Vivio unleashed the attack. The monster, not used to this sort of attack, shrieked in pain, parts of it still smoldering as Katara jumped in the air, water in her hand, to deliver a devastating forward water slice to its midsection, cutting it in half. With no Huu actually controlling the monster, it fell to the water, beaten.

It was a move Katara would never use on a human if she could help it. She looked over at Vivio. "You know, you're as good as your mothers! You;re pretty powerful!"
