Zetsuen no Tempest

Synopsis

Hakaze Kusaribe, the Magician of Genesis, awakens on a deserted island after being abandoned there inside a barrel. Some time later, while visiting the grave of his girlfriend Aika Fuwa, Yoshino Takigawa is confronted and threatened by a woman named Evangeline Yamamoto who asks him about the whereabouts of his friend, Aika's brother Mahiro. Mahiro arrives at the scene, and the two escape just as almost everyone else is afflicted by a strange disease that turns its victims' bodies into metal.
