Blue Cat

"Look who we have here... you a poor sap here to get in my way, or do you got something I want? Nyan!"
You seem to have encountered the Intergalactic Phantom thief named Blue Cat, whose real name is Yuni of Planet Rainbow.
Coming from a universal hell named The Dark Multiverse. A multiverse formed of every fear and bad decision ever made or dreamt. It seems you know this catgirl should've been a magical girl. But no... it seems she is but a thug now.
"What's wrong, wimp..... cat got your tongue?" she says this pun in a snarky way.
