30 Second Demon King

Once the undisputed sovereign of the abyss, the Demon King defied the divine order and paid a catastrophic price. Cast down by heavenly judgment, he lost not only his station but the very symbol of his power—his demonic horn, severed as punishment for his rebellion. To reclaim it, he is bound by an unforgiving penance: he must descend to the mortal realm alongside the enigmatic 'Princess of Hell' and together cleanse one hundred wandering evil spirits. For a being who once commanded legions of darkness, this task is a bitter humiliation, forcing him to destroy the very creatures that once swore him loyalty. Yet as he walks this precarious path of atonement, a far more insidious threat begins to surface. The Demon King finds himself plagued by unsettling gaps in his memory, moments of confusion that undermine his centuries of cunning and cruelty. The source of this creeping decay lies in the horn itself—for its loss does not merely diminish his power, but steadily erodes his identity, turning him into a stranger to his own past. Now, every spirit he purifies becomes a race against the void consuming his mind, all while he struggles to suppress his infernal nature and resist the urge to betray the very mission that offers his only salvation. In a world where ancient grudges and celestial justice collide, the fallen king must decide how much of his former self he is willing to sacrifice before he forgets who he is entirely.
