Hell's Awakening: The Guardian's RiseIn the fiery depths of Hell, where infernals, demons, and ancient creatures reign, the balance is fragile. At the heart of this underworld stands Azrael, the Guardian of Hell, a powerful being tasked with keeping the infernal realms from chaos and preventing the resurrection of fallen demons. With mastery over fire magic and the strength to command Hell itself, Azrael's existence is defined by vigilance and control.But when a powerful force of rogue infernals escapes their prison, led by a ruthless and vengeful faction, Hell’s foundation begins to crack. As these infernals break free, their goal is clear—to unleash an uprising and bring back the dead. Azrael must face not only these deadly foes but also confront his own inner demons. As the situation escalates, Azrael discovers his own potential for evolution—powers he never knew he possessed that could either save Hell or destroy it entirely.Amid this turmoil, the arrival of deities, including gods of light and purity, threatens to further destabilize Hell’s delicate ecosystem. They believe Hell must be purified, even if it means eradicating the guardian himself. As battles rage, alliances shift, and Azrael’s strength grows, he must decide whether he will uphold the order or reshape Hell in his own image.In this battle of gods, demons, and guardians, Azrael’s evolution is just beginning. The question is not just whether Hell will survive—but if Azrael will become its ultimate ruler—or its ultimate downfall.

The world was once at war with 10 alternate worlds. This was known as the Concept War and our world won 60 years ago. All of this was concealed so no normal people are aware of this fact in the current time.

After the death of his grandfather, the high-school student Sayama Mikoto is suddenly summoned by the giant corporation IAI. He learns this world is headed for destruction due to the acceleration of the Minus Concepts. To prevent this, negotiations must be undertaken with the survivors of the other parallel worlds so their 10 concepts can be released.

And so Sayama is caught up in the final battle to clean up after the Concept War which left behind so much enmity.

No family, no power, no inheritance — a thrice-lacking protagonist. Just how will the seed rise up from the mud?
