Reimu smiled and thanked the girls as she sat down.  "Well, when I first came to this world, I ended up in the air above the lake, and lost my grip on my sword as I fell.  Earlier today, I went to visit the merfolk to see if they had found it.  Turns out they did, and their prince wasn't willing to just give it back to me.  Not that I really expected him to, I suppose..." she explained before taking a few bites of her meal.  "Anyway, he did offer to give it back in exchange for a favor.  A succubus named Cerra had stolen something from him, a shell necklace.  He said there's nothing valuable about it, but it's a symbol of his leadership, so getting it back's still a big deal."<br/><br/>"So, that's why I need to find her.  She had said something about a factory while she was there, but that's the only information he could give me.  As for capturing her, he offered a larger reward if I brought her as well, for punishment.  Since you two were successful with that before, I figured you might know a bit about how to subdue someone like that."
