"As you know, there was a civil war between the demons. We were depleting the Netherworld's resources too quickly, so the demon queen decided that we'd invade your world for its reserves! Some of the weaker spirited demons didn't approve, and mounted a rebellion against the queen. One of the leaders of that revolt was Arthur! But he disappeared mid-battle! Whether he was injured or ran away, nobody knows. But the queen's supporters tortured me for days, trying to get information on his whereabouts! I started to think that I'd never again feel the cool waters of the River Styx, or taste sweet human tears until the queen intervened and stopped them! I owe her my life, ! I'd never betray her to get revenge on Arthur!"
