Angel Sanctuary - S01

Setsuna Mudo is a 16-year-old high school student doing his best to avoid trouble with the older students who bully him. His life is complicated further by his unrequited love for his younger sister, Sara, whom he only sees once a month. But beneath the surface of his ordinary struggles, something far stranger is unfolding. Mysterious beings-angels and demons-suddenly confront him, each insisting they know his true fate. The angels declare he is the reborn form of their leader, Alexiel, while the demons say he once commanded them in a war against God. Caught between these conflicting claims, Setsuna must grapple with his own identity as the ancient battle between Heaven and Hell threatens to erupt once more. The question remains: when the time comes, will he be ready?
