|Angel Sanctuary Character|
|Family:||Alexiel (twin sister)
Adam Kadmon (parent)
Rosiel is the Inorganic Angel Rosiel and the younger twin brother of Alexiel. Originally, he was a kind, wise and benevolent angel, but he knew that he would eventually lose his sanity and become destructive. He asked Alexiel to kill him before this happened, but her feelings prevented her from doing so and she sealed him within the earth instead. He is also obsessed with his beauty; because everyone calls him beautiful (save for Alexiel), he frequently asks if he is beautiful as he descends further into insanity. In fact, he intentionally mimics many of Alexiel's facial features, which explains his resemblance to his sister. In reality, Rosiel was born as an old, hideous creature. His body doesn't age; instead, it becomes younger and younger as time goes by. Rosiel's most loyal follower Katan secretly uses forbidden black magic to break the seal and brings Rosiel back. By this time, Rosiel has already lost his mind. Even with his determination to have Alexiel, he acknowledges on a subconscious level that he loves Katan more than anyone else in the world and occasionally shows this. In the final volume, Rosiel dies after killing his beloved servant Katan in a fit of madness. In his last moments, Alexiel awakens with Setsuna Mudo's help and helps Rosiel return to a temporary state of sanity. She reveals to him that she loved him as a brother all along. Rosiel realizes it is time he died and joined "the one he truly loves", Katan. He accepts death gratefully, but before he dies, though, he passes his powers onto Setsuna, giving three more wings to add to the three Setsuna already had, giving him a total of 6 wings, a trait once unique only to the "perfect" Holy Hermit Adam Kadmon.
