Angel Sanctuary

Setsuna Mudo is a troubled teen; he has a small number of friends and a large number of enemies, a disturbed personality, divorced and distant parents, and most importantly a sister complex torturing him to madness. As if things couldn't be worse, Setsuna suddenly finds himself launched into the eternal war between Heaven and Hell. It turns out that he is the reincarnation of the cryptic angel Alexiel, and it's his job to end this infinite struggle. But can this insecure Messiah, whose soul alone is torn between darkness and light, really find peace and save the world?
