Sixteen years ago, strange beasts known as Shifters flooded into the world. The King waged an intense war against them, using their summoning magic against them. Humanity created the Duobeast system, which swung victory in their favour.

As mysteriously as he appeared, the Prince of the Shifters vanished. He had marked thirteen children in his wake, who are now known as the Condemned.

The remaining Shifters lost territory day after day, and it seemed humanity had won. Until the oldest of the thirteen children exploded. Erupting into a beam of light, he transformed into a Portal. A huge influx of Shifters entered the realm, doubling their numbers.

Scientists worried each of the Condemned would transform the same way. Thus, fear grew about the potential power of the Shifters and the war effort grew more vigorous. Their concerns were valid. Ten years ago, one of the Condemned brutally murdered the parents of Shinsato Katsuro.

Focused on avenging them and ending this brutal war, Katsuro will stop at nothing. He must save humanity.
