Return with Dean and his friends to their second year of Demongate High, the only supernatural school on Earth. There are new talismans to make, new powers to explore, and evils, thought defeated, that may yet have their way. As a totally new power is discovered within certain individuals, strange things start happening around the school. Dreams of events long past start to surface as if they could come true in the future, but that's impossible, isn't it? Does this new power pose a danger to the very world? Osman thinks so, because if what he sees gets worse, Heaven itself might start bleeding into our world. But how can it be cut off, when it seems to stem directly from the All-Father? What's worse, Dean, Yasui, and Christina find out Seers can't tell their fortune. Does it have something to do with those people they don't know who recognized them last year? What exactly happened to them in the past? And what does it mean for their futures?
