In the not-too-distant past, the Ice Witch blankets the world in snow, starvation, and madness, leading the inhabitants to seek their salvation in fire. With that, an unusual destiny unfolds for two young orphans, Agni and Luna, blessed with the ability to regenerate. But will this ability prove to be more of a curse than a blessing?

With his promise to Tena imprinted on his mind, Agni can only enjoy an inauthentic peace coated thickly with lies. His existence blames, tortures and undermines him, becoming an affliction worse than the anger, pain and madness he'd experienced as Fire Punch. As Agni searches desperately for an escape from this hell, an old friend suddenly appears.
