“What? Is it that odd for us to have a bit of a chat? Whether I was a member of Gremlin
or not, I’m betting you would be treating me differently if I was a short girl with large
breasts that clearly wanted you to protect her.”

“Are you making fun of me?”

“That’s why I tried to make this easier by disguising myself as a girl you know.”

“Come to think of it, how did that work?”

“You wouldn’t understand me if I got into the details of the magic, so I’ll try to keep it
simple. In Norse mythology, when the thunder god had his weapon stolen, he disguised
himself as the goddess of beauty, Freyja, in order to lure out the thief. I put together a
disguise spell based on that legend, but that means I can only disguise myself as girls.”
