[She notices the footprints far too late, but the voice is unmistakable. As is the white object hurtling towards her face. She ducks quickly and it just barely sails over her head. She casts a glance back at the tree the snowball smacks against, as if to confirm what he just threw, then glares back at Marui.]

[Stooping down, she hastily scoops up some snow and begins shaping it. She maintains the glare, her tone firm, but it's clear that she's just playing around.

A little.]

You leave me no choice. I'm gonna have to take you down.

[She darts right, trying to throw him off with movement instead of standing still, and aims the snowball right at his chest. Hard. Like... maybe a little too hard.]
