Summary
Rosiel, an Inorganic Angel and the younger twin of Alexiel, was originally a wise and benevolent being who foresaw his eventual descent into madness and destruction. Rather than allow himself to become a threat, he requested that Alexiel kill him, but she was unable to follow through with execution and chose to seal him within the earth instead. As his sanity eroded, Rosiel became obsessed with his appearance, frequently asking if he was beautiful as others praised his looks, though Alexiel did not share this view. To mimic her, he intentionally adopted facial features that made him resemble his sister, a deception covering the truth that he was born an old and hideous creature whose body grows younger over time rather than aging. His loyal follower Katan eventually broke the seal using forbidden black magic to release him, at which point Rosiel had already completely lost his mind.
