Series: Angel Sanctuary
Age: He's an angel... been around for ages!
Notes: Angel Sanctuary has a very complicated story, so it's rough to sum up Rosiel here. He is Alexiel's twin brother, the Inorganic Angel Lord. He has strong love/hate feelings towards her, and is obsessed with recovering/awakening Alexiel (who happens to be reincarnated as the main character, Setsuna). Katan is his loyal servant and would rather see Rosiel in Heaven than persuing his sister.
