As Rex, a skilled yet sidelined figure in the game's hierarchy, he must navigate a world where he must pass on the mantle of heroism to the rightful main character and escape the burdens of saving the virtual realm. However, a puzzling twist arises as others in this new reality insist on labeling him as the hero, complicating his laid-back intentions.
