The Weather Outside is Frightful
Nero was used to being unusually warm. Ancient Rome wasn't known for it's chilly weather and she didn't name her blade 'Primordial Flame' because it sounded cool. Ok, so it did have a deciding factor in the naming process, but that was not the point here. The point was that it was ridiculously cold in Fuyuki City and Nero had no idea how to deal with it.
At first she believed that her natural warmth would power her through the snow and the ice, but the weather proved to be too much and she was left shivering in knee deep snow. There must be someway to- There. There was someone else outside.
Quickly latching on the other woman, Nero attempts to leech as much warmth as possible. Several seconds of leeching passed before Nero finally remembered she was attached to an actual person and not just a convenient heat source. "Ah... Hello there. Fancy meeting you here."
