You know, I was afraid of this exact scenario happening - my invisibility being disrupted and getting surrounded by enemies. Fortunately, the marines are a lot worse at hitting me than I thought they'd be.
All right then. Her character was actually inspired by a picture from, of all things, a mod for a game called Slay the Spire. Fans of Touhou may recognize the character the mod adds to the game. I, of course, really liked the mask.
I'm working on getting an actual picture for her (with the mask!), but that will take a few days.
