Warning: Possible spoilers!
The story of Rosiel's decent into madness is long
and complex. In the OAV we see Rosiel only after he is
risen and is already going insane. In the manga the story is longer. When Alexiel and Rosiel were born, Rosiel was little more than a hunk of meat. Alexiel begged God to give her brother a life of his own. God did so giving Rosiel beauty equal to Alexiels'. In return God demanded Alexiel harden her heart towards her brother. She did so much to Rosiel's despair. Instead of growing old Rosiel grows steadily younger. Knowing his sister refuses to love him and the knowledge of what his body really looks like drives him slowly insane. During the rebellion Alexiel leads against Heaven she and Rosiel face each other on the battlefeild. Rosiel's forces have vanquished Alexiel's but before she is captured she manages to seal her brother in the Earth with with a powerful spell.
