Demons Roots: Yakusoku Sareta Haiboku

The fall of the Demon Lord sent the remnants of his kind scuttling into the shadow of the Dark Realm, a desperate retreat born of utter defeat. For a thousand years, they eked out a meager existence in that forsaken dimension, their numbers dwindling with each passing generation. Now, teetering on the precipice of annihilation, demonkind has no choice but to mount one final, desperate gambit—an invasion of the human world, their ancestral home, in a last-ditch bid for survival. Yet the world they return to is a stark and bitter mirror of the one they lost. The intervening millennium has not healed humanity; it has fractured it. Rather than uniting against a common foe, men have turned their blades upon one another, carving the realm into fiefdoms of the powerful and prisons for the weak. The downtrodden masses, crushed beneath the heel of their own victors and rulers, find themselves without hope, their cries for justice swallowed by the apathy of the ages. It is in this shared misery that an impossible alliance is forged. The very demons once feared as monstrous invaders emerge as the unlikeliest of saviors for the oppressed. Together, the outcasts of both races rise against the established order—the tyrannical victors who hold all the reins of power. Their common goal is no longer conquest for its own sake, but a desperate crusade to shatter the chains of their oppressors and carve out a sanctuary where both human and demon can finally call home.
