Insignia follows Red, one of the few insignia users, in his journey within the fantasy world of Inariel, and the magical guilds within it. The world of Inariel is a world full of magic, and dangerous monsters. Red, accompanied by his allies, Luna, Amelia, Hironi, Elias, and Sole, will take on the challenges of this world, from monsters to a deadly band of killers that go by the name, The Tenyi. The inhabitants of this world can possess magical abilities known as arcanas, which give them abilities unique to them. Some arcanas are weak but others are strong enough to defeat an army. The ones with stronger arcanas advance and join one of the great mage guilds, who serves the purpose of protecting those that can't protect themselves. Red belongs to the Mage guild Elune, one of the legendary three guilds.
