As the Altar of Ascension becomes the epicenter of a brutal war, Hagane must navigate the shadows of his past and the threats of the present. Armed with his Divine Gift and insolent charisma, he ventures into a battlefield where void creatures and enigmatic foes seek his downfall. Yet behind his smile and carefree demeanor lies an internal struggle, an echo of unfulfilled promises and the fear of failing to protect those who depend on him. Facing a rival who defies the impossible, Hagane must decide if his unwavering confidence is enough to save his students—and himself—from an uncertain fate.
