Surtr

At the end of the last century, Tokyo encountered 23 other worlds, everyday life and common sense collapsed. More than 15 years have passed since then... the children born are now high school students. The story begins at Fujimi Academy in Tokyo. You awaken in a version of Tokyo where "transients" – supernatural beings from fantasy and mythology – live among humans. In this world, both humans and transients utilize mysterious artifacts to fight in duels; duelists organize into guilds, which fight for control of the 23 special wards of Tokyo. Surtr is a Transient from the world of Yggdrasil and member of the Otemachi Genociders. In addition to his flaming Sword Sacred Artifact, which can burn the safeguards of worlds to ash, he also wears a black Helmet Sacred Artifact which etches fear into his target. In memory of his perished children, he will never remove the helm. Any who express their flame-like existence are beloved as his children.
