Those who destroy these demons and run the highest risk of all are tactical sorcerists known as Strait Jackets . But when terrorists unleash a plague of demonic carnage, the Sorcery Management Bureau must enlist unlicensed assassin Leiot Steinberg to stop the slaughter. Even if this rogue killer and a mysterious young girl can end the outbreak, will they be able to face their own dark secrets?
