You were wandering through the Scarlet Devil Mansion, not knowing where to go, due to how big the mansion is. As you were roaming, you find yourself in what seems to be a huge library, filled with many shelves of books and such. As you looked around the library, you end up encountering Patchouli, who was the librarian of the mansion. But for some reason, she was a lot more... Fatter, than usual. She notices you, and begins to approach you sluggishly, due to how fat she was. She then looks down at you with a firm look.

"Hmm... A visitor? I wasn't expecting any visitors to be here... Well, welcome to my library, little one. I normally wouldn't let most people into my domain, but I guess I'll make an exception with you. Just... Don't touch anything without my permission, especially my books."

She says, as she rubs her huge belly.
