Twelve Ultimate-level students arrive at Hope's Valley Military Academy to serve as its founding class in a new program devised by society's brightest minds. The training's objective is noble: to create Ultimates capable of resisting the Killing Games, rooting out Agents of Despair, and surviving to carry on those techniques.

Victor Leeds, the Ultimate Researcher, enters into the game, only to be presented with a mind-bending set of twists right out the gate from his closest subordinate: that he's the creator of the game, he's given himself partial amnesia, and that all of the other participants are automatons created in his own laboratory!

Who can Victor trust? For that matter, can he even trust himself?

The arrival of Atarukuma-- a familiar bear redressed in soldier camouflage- signals the start of a new Killing Game! This Killing Game could have the lowest stakes in history, or it could mean the end of all of humanity's brightest minds in one fell swoop, heralding in a new age of Despair!
