Banshee

Banshee is the deputy of Viking, she also plays the role of the bodyguard.
While being by the side of Viking, she learns that not anyone wants to be governed by a gigantic organization like UED, once again; that is, people against Viking will eventually step in her way.

Unlike Viking, Banshee enjoys pure combats rather than using them as a "conversation tool", and she even finds out that putting missiles directly into enemies' mouths seems to be more interesting than firing them from the sky.
