At the Death Weapon Meister Academy, humans born with the power to transform into weapons and those with the power to wield these weapons (Meisters) train to hone their natural talent. The characters of the main series are enrolled in the Especially Advantaged Talent class, where they train to become warriors of justice capable of defeating what threats prey on innocent lives—or even the entire world.

As they learn to use these powers and settle in, their lives as everyday students will be far from normal.
