This is Exitium. Well don't want to spoil the story or anything, but all I can say is that this character is one of many enemies #7 faces. Exitium is a prototype manufactured Insegnius. Just like the main character too. She's a walking dynamite, meaning she's a person who loves explosions. Everything about her gear will show you that she isn't playing hide and seek. Everywhere she goes, will be destroyed with no consequence to kill her target. Good luck #7...
Now about these manufactured clones of Insegnius... They are basically tamed for specific uses of army artillery and well these "prototypes" are weapons for the Elite Cresent Army. Each prototype is special in their own way and have their own set of skills or expertise. Some of them are horrifically experimented on so bad that they are something much worse than an original Insegnius.

Hopefully the music is ok, I'm just working on it as I progress.
