The Warlord's Revenge

Vonruil smirks and says, "I gave it before I got pushed into the Abyss Black Hole." 


Lucy smiles and says, "Oh, then he deserves it. Oh, and as for Siban and Rival. Well, it's like this; from what I heard, Siban knows the scrolls are with Coven Spirits World and us. Sooo, Rival has promised Siban that if she gets the scrolls for him, Rival will help her get her spear back from Satan. Now why his spear is with Satan, that I don't know. Oh, and as for the humans she's killing. If I didn't hear wrong, his messenger, I mean Satan's messenger, is here. She's looking for him." 


Travis says, confused, "Why does Satan have a messenger on earth?"
