Five hundred years ago, the brave Elven Mage-Knight Artorias Wind-Caller and the cunning human bard Terpsichore Ironheart joined forces against the cult of the heinous Demon King Paimon, thwarting his plans to conquer the mortal realm.

Today, their grandson, Joseph Ironheart, is an elven teenager living in a human-dominated society. The unicorns are dead, their glades burned, and the Mage-Knights who once rode them disbanded. And yet he still dreams of a better future, with a gun in his hand and a motorcycle between his legs.
