Abaddon

"Possesses huge sickle-like wings and green scales cover his enormous body with a tail like a dragon." It is said that all who look at Prince Abaddon die instantly. Kurai was one of those exceptions, because she was wearing one of Setsuna's earrings on a necklace, and Abaddon was to acknowledge her as his "mother". He is of noble blood, but he was chained in the deepest dungeon in Hell under the care of Astaroth when Lucifer's soul disappeared. He escapes and crashes Kurai's wedding to Lucifer. Abaddon dies protecting her from the collapsing chapel.
