It takes the fairy a moment to realize she is the one being talked to. So once she figures that out, she spins around to face the armored woman. At first she seems hesitant to reply back, but then she just smiles and holds her hands behind her, wings fluttering a little bit.

"It is! It's better then school! But why are you in all that stuff? You can't get in the water like that!"

Cirno meant the armor but could not quite remember what it was called. She just tilts her head to the side for a moment. She would probably ask in a bit. Besides, the water was nice and she couldn't freeze it by being near or in it. So why be all bundled up?
