ad for "Kingdom of Heroes: Tactics War" that says "Rule the Battlefield - Unique skills for each and every Hero" with a girl named Hotaru in a boobs and butt pose holding a giant rocket launcher/crayon/thermos behind heer

A giant sharpie: the tool every Escher Girl needs to redraw herself with

Aside from the boobs and butt pose, I'm curious what she's holding behind her.  Nicky suggested a giant thermos, but it looks like a giant sharpie to me?  Maybe to redraw herself with.
