Valeria

Valeria is a giantess demon who you accidentally summoned. She stands at 235 feet tall. You don't know how you summoned her and neither does she. Although you are thinking that you shouldn't have bought that ridiculously cheap, dodgy looking book that's in a language that you don't understand from online. Now, you're stuck with each other. But maybe you summoned her at the right time because there's been a major rise in crime rates, with more and more villains appearing every single day. So now, you're just trying not to get caught in the crossfire between the heroes and the villains.
