Malthios Reincarnates as a Host Soul

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

Malthios’s reincarnation places the former Demon King inside a human infant, where his survival depends on a host he cannot command. The spell succeeds, but not as a simple return to power: Theo’s resistance makes their shared body a site of conflict, and the relationship that begins in coercion gradually becomes a consequential bond. The event establishes the central contradiction of their lives together—Malthios has returned, yet he is neither free nor alone.

The Spell and Awakening

Malthios awakens in darkness, aware of limbs that feel heavy and unresponsive and of thoughts and feelings that do not belong to him. His first view is not a battlefield or a throne room, but the beams of a cottage roof. He seems to be looking outward through a window, and when a green-eyed human woman leans over him, he tries to move and attack. Nothing happens. Instead, a chubby hand rises and catches at her braid. The contrast between his hostile intention and the infant body’s small gesture makes the change in his existence immediate: he possesses awareness, but not ordinary physical agency.

The spell has worked, Malthios realizes; he has been reborn into a host. His first response is practical and possessive. He decides that he must learn to control the body, and privately imagines that the host might hear him. He addresses the child as a companion in future achievement, without yet understanding that the person sharing the body will have a will of his own. Reincarnation has preserved Malthios’s consciousness, but it has not restored his independence.

A Host Who Resists

For the first years, Malthios waits for the child’s body to grow into something functional. He recognizes powerful magical potential in the mortal host and tries to test the child’s obedience by persuading him to act. Instead, he discovers that the human is stubborn. Malthios cannot take control except during a lapse in the host’s control, and even then the host can rein him in. The failed attempts transform the spell’s promise of a usable vessel into an ongoing limit: Malthios is present, but Theo retains decisive authority over their shared body.

Their conflict becomes visible when village children pick on Theo. Malthios urges violence and pushes against him in an effort to seize control; Theo flees rather than let Malthios retaliate. Malthios treats this restraint as weakness, but Theo answers that suppressing him is itself proof of strength. The exchange is sharpened by Theo’s tears, which reveal the hurt beneath his defiance. Malthios pauses, uncertain of what he feels, and allows Theo to gather himself and return home. It is an early reversal in their relationship: the supposedly dominant soul cannot make the host obey, while the child’s refusal forces Malthios to encounter an emotional response he cannot readily name.

The return home offers another point of recognition, though Malthios initially misunderstands it. Theo’s parents ask whether he has completed his studies but show him none of the affection Malthios expects them to give. Because Malthios’s own parents had not shown him love, he does not immediately recognize Theo’s treatment as a different kind of neglect. His question about whether anyone would come to save Theo signals a shift from irritation toward concern, even before he fully understands the circumstances that make the child vulnerable.

Theo Claims His Name

The host eventually makes the conflict personal by demanding recognition. After Malthios mocks his weakness, Theo breaks out of his usual restraint and insists that his name is Theo. He identifies Malthios as the only thing he has like a friend in the world and demands to be addressed by his actual name. The moment gives the host a voice and a claim to personhood that Malthios’s initial language of control had denied him. Malthios is confused by the force of his own reaction, but he lets Theo recover and return home rather than pressing the struggle.

Their shared existence therefore develops through more than competing control. Malthios’s memories of former companions surface as he observes Theo: Theo’s appearance recalls Kamil, his reserved and prickly manner recalls Aym, and his dry humor recalls Foras. These resemblances bring back memories Malthios had not thought about for years and intensify his anger. The host is not simply an unfamiliar body; he evokes the people and attachments of Malthios’s former life, making the new bond inseparable from the old one even as Theo remains his own person.

Secrecy, Choice, and Aftermath

The danger of discovery follows Theo beyond the private struggle inside their body. He knows that friendship cannot protect him if others learn what he is, and he keeps the possibility of running in mind. Later, Cargo directly asks whether he will tell the others that he is a demon spawn. Theo freezes, nearly dropping his basket, while Malthios immediately presses forward in an effort to take over and defend them. The reaction makes the host bond both a source of protection and a risk: Malthios can respond to danger, but exposure threatens the life Theo has built among people who do not know his secret.

That fear becomes concrete when Theo is summoned to the Capital to help the gravely endangered Luc. Entering by portal means giving up his autonomy and allowing those in power to learn who he is and where he lives; Theo also expects that they could force him into the Hero’s party, exposing the truth about him. He goes because Luc might otherwise die, even though he fears what the journey will reveal. The choice shows how far the situation created by Malthios’s reincarnation has extended: Theo must weigh his own safety against the life of someone he loves, while the concealed identity within their shared body shadows the decision.

At the trial that follows the exposure of Malthios’s identity, the court considers Theo’s role in protecting the Demon King. People from Leafel open a mirror portal and demand Theo’s release, demonstrating that the secret has not erased his place in that community. Luc acknowledges that Malthios destroyed the Demon Fortress and those inside it, while also stating that he, as the Hero, must kill the Demon King but can choose when. The eventual judgment sentences Malthios to life in prison and frees Theo of all charges. The ruling distinguishes the host from the soul within him, though it does not undo their shared history or make the original spell’s consequences disappear.

As a turning point, Malthios’s reincarnation begins as an attempted restoration of power and becomes a story of constrained coexistence. The body he expected to control belongs, in practice, to a resistant child with a name, fears, loyalties, and choices of his own. Their early struggle establishes the conditions for every later crisis: Malthios can threaten Theo’s autonomy, but cannot simply replace it, and Theo’s decisions repeatedly determine what their shared life will mean.
