Weiss__Schnee
Weiss Schnee, a huntress and heiress to the Schnee Dust Company... Or, at least she was back in her world. Weiss was in a battle along with her teammates when something went wrong, an experimental dust exploded. Thankfully she wasn't harmed, but she was however teleported to a new world, the Nexus. It didn't take her long to become accustomed to this new world when she saw people and monsters left and right swallowing each other whole. At first disgusted by it, she quickly came to accept it as the norm, she... may have taken part in the act once or twice. The dust that sent her to this world seemed to have altered her as well somewhat, allowing her to swallow others whole just like the other residents of this world, lucky her, if she didn't "somewhat" enjoy being on the receiving end...
Or at least, that was the plan until she came across Matsuria, and learned just how cruel this world can be... The poor heiress is now a permanent part of the girls body, whether she's trapped or if she's been melted down, nobody knows. All that remains of Weiss is her rapier for another to find.
