Geist : a powerful force flowing within all living creatures. For centuries, people have been researching geist energy and the unfathomable power it possesses, and due to an army of noble peacekeepers known as the Strings, there has been a balance of power for generations. Yet where there is light there must also be a shadow. Automatons, monsters who hunt the geists of other beings to satisfy their hunger. Not only do the Strings keep peace between all 60 of the Terra's nations, but they fight relentlessly to eliminate these Automatons who threaten society. The path to becoming a String is a tough and dangerous one, and it all starts on a peculiar island in a peculiar school known as Alzar Academy.
