Welcome to the fantastic world of Bios. Another world, not much unlike our own, with some exceptions, such as, say, the presence of gods, demons, and magic. While things like these were once common knowledge, the Great Witch Hunt, which occurred 500 years ago, forced most of the magicians who survived into hiding, and many of the old religions to disappear, with the exception of a few. And so, as time went on, history was rewritten, and those amazing things became, to the population at large, the stuff of legends.

However, in the year of 2017 A.S. (Anno Salvator), a group of teenagers find themselves pulled into the magical side of Bios as they encounter the Magic Knight Forces, discover dark secrets, and realize that a great threat is rising from its long sleep... The time for the supernatural to come out of the shadows is coming.
