Demon Ascension

The Reincarnated Demon King's Host Just Wants to Live in Peace, But the Hero Won't Leave Him Alone

Demon Ascension is the system by which demons rise through a hierarchy of power, with advancement bound to the taking of innocent lives and, at its highest level, to a test of worthiness. It shapes both the structure of demon society and Malthios’s history, turning an imposed act of mass killing into the threshold of his ascent—and making his later rise to Demon King a distinct, more mysterious transformation.

Ranks and Conditions

The hierarchy begins with Demonkin, the lowest group, who have little or no mana or magic but can serve as ordinary soldiers. A Demon Lord can sponsor a Demonkin by granting them mana; those who survive become Novices. Their magical potential varies, while their physical prowess makes them especially suited to combat. This transfer of power is painful: Malthios survived the mana given to him by Fulton, though he remembered it as one of the most painful experiences of his life.

The next ascent has a brutal condition. Demon Lords gain immense mana and grow wings after slaughtering large numbers of innocents. The process is not presented as a formal test with a stated count: when Malthios and four companions were judged ready, Commander Ovrtu told them each to kill a whole bunch of innocents. Malthios’s own transformation followed a massacre in a mortal city, where the order was to kill every living thing they encountered. The hierarchy therefore makes atrocity not merely a tactic of demon rule but the stated price of advancement.

The Demon King Threshold

The highest rank follows a different and deliberately less transparent rule. Only Demon Lords know how a demon may ascend to Demon King, and the transformation is not guaranteed by slaughter alone: it succeeds only if the demon is worthy of the power. No Demon King had existed for many years before Malthios’s rise, leaving the final step less a predictable rung in the hierarchy than a rare judgment whose terms remain concealed.

Malthios’s ascent came amid revenge for the Pentagram. After Naamah revealed that she had knowingly sent the group into danger from the Hero, Malthios attacked her, fighting through her Novices while the deaths of Aym, Torq, Foras, and Kamil filled his attention. He killed Naamah, and his mana surged as it had during his earlier ascension. Before the assembled Demon Lords, his glossy black feathers turned dark blood red: the visible sign that a new Demon King had risen. The transformation follows a massacre of demons rather than the prescribed slaughter of mortal innocents, making Malthios’s accession a violent rupture within the hierarchy as well as its fulfillment.

The crown did not erase the danger of succession. Fulton identified Tyraz as the Demon Lord most likely to have become Demon King had Malthios not beaten him to it, describing him as a master of shadows. Malthios openly asked whether Tyraz would kill him for the crown; Tyraz admitted that he would. Malthios nevertheless offered him the position of second-in-command of all demonkind, which Tyraz accepted. Their exchange makes the hierarchy’s central tension plain: ascent establishes a ruler, but not security from ambitious challengers.

From Survival to Transformation

Malthios’s ascent began against a childhood in which survival, not rank, was the first contest. His parents’ faces had faded from memory, and he had been abandoned before his sixth year; left to himself in a demon village, he stole food and endured until a Demon Lord came to recruit children who had survived the gift of mana. The society around him valued power over blood ties, while his own earliest memories were marked by pain. His later place in the hierarchy therefore came not through inheritance but through successive trials imposed on a child who had already learned to persist without protection.

The cost of his first major transformation became unmistakable in the mortal city where he and his companions were ordered to kill every living thing they encountered. As Malthios slew the last person around him, his mana surged to twice its former size. The pressure broke outward as two feathered wings unfolded from his shoulders, tearing through his armor and shirt; his joints and fangs ached, and his muscles stretched as if in a sudden growth spurt. He stumbled toward the gate, uncertain of his new wings, where Kamil was waiting. She ran to him, her own wings white and speckled with red-brown, and embraced him despite the blood on them both. Her delighted greeting framed the transformation as a shared achievement, even as its cause remained the slaughter demanded by their commanders.

Power, War, and the Meaning of Ascent

Demon Ascension belongs to a wider conflict rather than a closed ladder of status. Even after Malthios’s defeat, remnants of the Demon King’s army remained across the land under surviving Demon Lords, while the Hero’s party continued to protect ordinary people. Advancement therefore replenishes and reshapes the leadership of an ongoing military threat; it does not itself bring the conflict to an end. The contrast between the system’s language of power and its human cost is built into its operation: the path upward is measured in mana, wings, and rank, but its price is paid by the lives of innocents.

The sequence also distinguishes visible transformation from legitimacy. Becoming a Demon Lord has an explicit, gruesome condition and recognizable bodily signs; becoming Demon King is rarer, and its rule remains known only to Demon Lords, with worthiness as its stated constraint. Malthios’s rise after killing Naamah shows that the highest transformation can emerge from an act of revenge within demon society, not simply from the prescribed slaughter of mortals. In that reversal, the hierarchy’s promise of advancement becomes inseparable from the violence it was built to reward.
