About

The world of Hazama exists in the gaps between all other worlds. In this once-peaceful land, the Demon King has suddenly begun kidnapping people! Karma, Rinne, and Fate—three siblings—travel across Hazama to find the "Barrier Shards" needed to destroy the barrier protecting the Demon King's castle. You are free to travel this world as you please. Will you side with Karma and his siblings, or aid the Demon King? Of course, you could just live a normal life, or even destroy everything.
