Lust
Lust is one of the Seven Sins, a collection-production grimoire whose purpose is to become the “ultimate womb” and produce a child superior to every preceding generation. Rather than perfecting its own body, Lust collects genetic information, breeds lineages, and uses terminals to influence or occupy other bodies. Its centuries-long control of the Middle Kingdom culminates in Lust's Apocalypse and the heavenly-demon project, after which its local terminal is destroyed without establishing that the remote grimoire itself has permanently ceased to exist. (Chapters 249–251, 357–376, and 397–398)
Biography
East Continent and the Northern War
Lust first confronts Theodore Miller through Shim Samho, an imperial notary whose body functions as a remote terminal. Removing the woman's veil subjects Theodore to myth-grade mental interference and nearly overrides his reason before Gluttony resists the effect. Theodore's counterattack kills the human body, but Lust continues speaking until its remote connection fails. Gluttony recognizes the other grimoire and invokes an existing non-aggression promise between them; Lust accepts that Theodore is Gluttony's host and withdraws rather than turning the accidental encounter into open conflict between two Seven Sins. (Chapters 249–250)
After the terminal collapses, Gluttony explains Lust as a collection-production grimoire whose reproductive and domination abilities serve one purpose: producing a descendant superior to its parents, repeating the cycle until an ultimate being is born. Lust collects and stores genetic information through reproductive behavior, evaluates combinations, and uses power bases as infrastructure rather than seeking government for its own sake. Gluttony therefore suspects that the Middle Kingdom's imperial family is the product of Lust's long breeding program and that its position as imperial notary helps it collect strong candidates and control disputes. These details are Gluttony's reconstruction, not a confession Lust gives during the first meeting. (Chapters 250–251)
The same explanation establishes both the scale and the uncertainty of Lust's project. It previously developed the Ulfheðnar through repeated inbreeding, then abandoned that line after Fenrir's inability to reproduce made further advancement impossible. In the East, Lust appears to broaden the genetic pool through the empire rather than repeat the same method. Gluttony argues that a heavily engineered birth may make true self-transcendence harder, while conceding that Lust might eventually produce transcendent value from birth. The outcome is therefore neither guaranteed nor meaningless: by the northern war, the imperial descendants are dangerous, but the “ultimate” child remains an unrealized objective. (Chapter 251)
Prometheus and the Eastern Apocalypse
Five years later, the expulsion of Sloth forces Lust to accelerate. Because the world's mana will decline over the coming centuries, the conditions needed to conceive upper species are closing. Lust activates the latent blood inherited by its descendants across the Middle Kingdom, transforming much of the population into variants that express fragments of Ulfheðnar, Arv, vulcan, and other discarded parent lines. Gluttony interprets the mass mutation as a final selection: Lust is searching for an exceptional result while treating the countless failed transformations as expendable. The catastrophe begins from the capital and destroys ordinary government, agriculture, and human survival across the empire. (Chapter 357)
Abe no Seimei reveals that he too is Lust's child, born from the grimoire and a nine-tailed fox. Lust once imitated a maternal role because his potential made him valuable as a protector, but his father helped him escape, and Seimei later reached transcendence independently. Even that did not free his inherited body completely: when he attacked the capital, Lust's authority over its bloodline paralyzed much of his power and contributed to his defeat. The later feudal princes are likewise the products of generations between Lust and the imperial family, with enhanced chances of manifesting upper-species bodies and variant powers. Their descent does not make them extensions of Lust's personality, but it gives the grimoire biological leverage and channels through which to observe the war. (Chapters 357–358 and 363–364)
At Hyungkang Castle, Lust demonstrates how its weak direct combat ability is offset by domination. Its arrival overwhelms soldiers, variants, the sword master Wichung, and Sylvia Adruncus; even Veronica almost submits merely by looking, surviving because pain and her soul agreement with Theodore let her turn away. Lust orders the transformed King Hodae to pursue Veronica, preserves Wichung only as a messenger, and kills the remaining inhabitants and variants once they have no further value. It then takes Sylvia, implants a same-sex terminal in her body, and uses that occupied body as protection when it meets Theodore, rather than exposing a separate vulnerable incarnation to his attack. (Chapters 365–368)
Lust values Sylvia for two stated reasons: her unusual mana-loved constitution makes her a desirable reproductive vessel, and her importance to Theodore makes her leverage. It proposes exchanging Sylvia's freedom for Theodore's genetic material. The terms matter. Lust says an early same-sex terminal can collect genetic factors but cannot impose its irreversible sexual domination, and Gluttony invokes the Pledge of Sin, a system-level promise that even a fully unsealed Seven Sins cannot break or evade. Under that pledge Lust must not harm Sylvia and must return her to the West. Sylvia regains control before consenting to intimacy with Theodore; Lust is not presented as Sylvia's consenting identity or as Theodore's partner in that encounter. (Chapters 368–370)
The heavenly demon is the product of Lust's final project, not Lust's name, personal body, or promised ultimate success. Knowing the probability of perfection is low, Lust concentrates the empire's population, shamans, inherited bloodlines, and accumulated power on one birth; the expected failure will still provide data that can be transmitted to its main body. Theodore turns the bargain against it by placing Mutual Destruction in the genetic material Lust takes. He defeats the heavenly demon in direct battle first, then releases the embedded spell; when the dying demon tries to reverse along that path as information, the process destroys eighty percent of its remaining existence. Lust shows no maternal grief, calling the child another trial whose defects yielded useful information. Its burned terminal then collapses, after warning that it will take 10,000 years to appear again and hinting at the destruction later identified as Wrath. (Chapters 365 and 371–378)
Marriage, Armageddon, and the New World
The later confrontation with Gluttony clarifies why Lust's collapse should not be described as an ordinary biological death. A Seven Sins grimoire remains in the material world unless its host is destroyed, overwhelming firepower eliminates its manifested structure, or it is banished across dimensions. Theodore recalls Lust as the example of a defenseless grimoire and distinguishes that case from Gluttony's contracted body. Combined with Lust's own statement that only its terminal was dying and that reappearance would take millennia, the evidence supports local destruction or eviction, not proof that every remote part of Lust was annihilated permanently. (Chapter 397)
Lust nevertheless leaves immediate historical consequences. Six months after Armageddon, the former Middle Kingdom remains shattered by the event called Lust's Apocalypse: its imperial system has collapsed, most of its territory is exposed to neighboring armies, and survivors live among remaining variants. Theodore refuses to rebuild the old empire by personal dictatorship. Instead, Meltor supports a New Central Kingdom centered on the Fairy Dance Lee family, while Japan accepts refugees and territorial responsibility. This reconstruction contains Lust's political aftermath, but it cannot restore the enormous population consumed by mutation, sacrifice, civil killing, and the heavenly-demon project. (Chapter 398)
The final chapter also separates Lust's bargain from Theodore and Sylvia's family. Sylvia gives birth to Adellia, whom the narration explicitly identifies as the child inheriting Theodore's and Sylvia's blood. Lust is not named as a parent, controlling presence, or designer of the baby, and the heavenly demon has already died. The earlier terminal collected Theodore's genetic material through the negotiated encounter, but the corpus does not state that it altered Sylvia's child or retained authority over the pregnancy. Lust's last established legacy is therefore the ruined empire and delayed possibility of return, not membership in Theodore's marriage or ownership of his daughter. (Chapter 398)
Appearance and personality
Lust has no single reliable human appearance in the covered chapters because it operates through bodies and terminals. Shim Samho appears as a veiled imperial notary whose revealed face, white skin, and body overwhelm Theodore's cognition, but the corpse becomes an ordinary dead woman as soon as Lust's remote link breaks. Later, Lust appears as an extraordinarily beautiful woman at Hyungkang Castle, then occupies Sylvia's silver-haired body for negotiation. Those faces belong to distinct vessels; their beauty is amplified by Lust's power, and none is established as the physical form of the remote main grimoire. (Chapters 249–250 and 366–369)
Its speech and gestures are deliberately provocative. Lust laughs, exposes bodies, uses intimate forms of address, and tests whether desire can break an opponent's concentration. These behaviors are tactical extensions of its function as much as personality: when Theodore refuses to react to Sylvia's body, Lust becomes bored and returns to negotiation. Attraction should therefore not be read as romance. Lust initially calls Theodore desirable genetic material, later pursues his post-transcendent lineage, and treats Sylvia's qualities as a reproductive evaluation. Its interest consistently points toward usable heredity and leverage, not a supported claim of affection for either person. (Chapters 249–250 and 368–369)
Lust is patient, calculating, and radically instrumental. It can manage bloodlines and political institutions for centuries, usually stays neutral toward other Seven Sins, and uses a system-level pledge when a bargain needs credible enforcement. At the same time, it spends the population of a continent on a low-probability project, discards descendants that no longer advance its goal, and expresses satisfaction with data obtained from the heavenly demon's failure. The narration explicitly denies maternal sentiment toward that child. Lust's candor in describing its purpose and honoring the Pledge of Sin is real, but neither quality supplies human empathy or an ethical limit. (Chapters 250–251, 357–369, and 376)
Magic, abilities, and martial skills
Collection-production and reproductive design
Lust's core function is the collection of genetic information and the production of improved descendants. Through reproductive contact it can analyze and store genetic factors, assess the potential of a womb, select traits, and attempt to produce children whose bodies, minds, and souls exceed those of their parents. This differs from a grimoire that modifies itself: Lust acts as incubator and breeder, while the resulting child remains a separate organism. Its earlier Ulfheðnar line, Seimei, the Middle Kingdom's imperial house, the feudal princes, and the heavenly demon are different outcomes of this method rather than successive forms inhabited by one consciousness. (Chapters 250–251, 357–365, and 369)
The method has severe limits. Improvement requires generations, viable reproductive material, and environmental power; a line can reach sterility or amplify defects, as Fenrir's case demonstrates. Gluttony argues that inherited excellence can burden rather than guarantee self-transcendence, and Lust itself accepts that the heavenly-demon project will probably fail to produce the ultimate creature. Declining mana also threatens future upper-species births, prompting the final gamble. Lust can force selection and combine traits on an enormous scale, but it cannot simply design a perfect transcendent on demand or ensure that a powerful child will remain obedient after escaping its bloodline authority. (Chapters 251 and 357–365)
Fascination, binding, and bloodline authority
Lust's visible presence carries myth-grade fascination called Burning Carnal Desire. Sight, scent, voice, gesture, and direct contact can overwhelm a master's reason even without intercourse, affecting men and women alike. Gluttony can resist it for Theodore, while Veronica survives by inflicting pain and anchoring herself to a preexisting soul agreement. These cases are exceptional defenses, not evidence that ordinary willpower is sufficient. The direct reproductive binding is stronger: Gluttony describes the partner as willingly subordinate even while knowing manipulation occurred and says the condition cannot be released. Lust acknowledges that this strongest control does not operate through an early same-sex terminal used only to collect genetic factors. (Chapters 249–250 and 366–369)
Its authority also extends through inherited blood. Lust can activate dormant upper-species factors across a vast population, influence descendants, and observe opponents through imperial variants or princes. Seimei reaches transcendence and escapes ordinary causality, yet inherited commands still suppress much of his body when he attacks his mother. The precise boundary is not quantified for every generation, and not every mutated person retains intelligence or direct communication with Lust. The apocalypse produces uncontrolled, hungry variants as well as obedient masters, demonstrating that bloodline activation is a mass selection mechanism rather than perfect, continuous puppetry over every descendant. (Chapters 357–364)
Terminals, hosts, and survival
Terminals let Lust act at a distance without presenting the main grimoire. Shim Samho remains biologically dead after Theodore's attack, but Lust speaks through the body until the connection expires. A later terminal can appear separately, dominate Hyungkang Castle, and then be planted into Sylvia as a same-sex host. In that configuration Sylvia loses bodily control and begins to suffer erosion; if placenta formation progresses, the narration says there is no recovery from becoming one of Lust's people. These examples distinguish three layers: Lust's remote main existence, the local terminal carrying its agency, and the host body that can die or be returned independently. (Chapters 249–250 and 366–369)
This distributed operation improves survival but does not make a terminal durable. Lust admits it has no direct combat skill, cannot regenerate Shim Samho after a 7th-circle attack, and relies on fascination, descendants, fortifications, or hostages to prevent opponents from reaching it. The terminal damaged during Geongun Castle's destruction is unable to stop Theodore and crumbles on its own shortly afterward. Its prediction of a 10,000-year absence implies a profound cost to losing that manifestation. The corpus does not explain where the main body resides, how a new terminal would be produced, or whether Lust can shorten that interval from outside the material world. (Chapters 250, 365–376, and 397)
Variants, fortifications, and the heavenly demon
Lust converts its accumulated population into both experimental material and military infrastructure. The triggered descendants become variants with uneven upper-species traits; imperial princes may retain reason and command, while many ordinary victims become predatory failures. Human sacrifices and stored shamanic power sustain Geongun Castle's deliberately simple ward, whose enormous energy supply withstands direct transcendent attacks. These are resources Lust organizes, not personal martial techniques. Once Theodore opens Muspelheim inside the barrier, the trapped heat destroys the castle's army and most of Lust's local power because its defense is built to repel entry from outside rather than an attack originating within. (Chapters 357–365 and 371–373)
The heavenly demon is a newly born combatant assembled from the project, not a transformation of Lust. It carries near-limit genetic capabilities, incomplete spiritual scars, absorption, sacred-creature powers, magic, and shamanism, and it nearly defeats Theodore before falling to Grand Cross. Theodore then releases Mutual Destruction; the dying demon converts itself into information and follows the suicide spell back toward him, losing eighty percent of its remaining existence during that reversal. Its defeat confirms the project's destructive reach but not the birth of Lust's intended ultimate child; Lust calls the result a source of satisfactory defect data. The demon's combat record therefore should not be added directly to Lust's own fighting rank, which remains dependent on control, breeding, and preparation. (Chapters 365 and 372–376)

Relationships
Theodore Miller and Gluttony
Lust first treats Theodore as attractive genetic material and Gluttony as a peer protected by old Seven Sins rules. The non-aggression promise ends their accidental encounter, but it does not prevent later conflict after Lust's apocalypse threatens the world and targets Sylvia. Lust then negotiates with Theodore through the Pledge of Sin, correctly assuming he will pay to protect Sylvia, yet underestimates his ability to make the payment itself a trap. After Theodore defeats the heavenly demon, his Mutual Destruction spell destroys most of the remnant when it attempts to return through the implanted connection. Their relationship is strategic throughout: genetic interest, hostage pressure, enforceable exchange, deception, and eventual destruction, without evidence of mutual affection. (Chapters 249–251 and 357–376)
Sylvia Adruncus and Veronica
Lust sees Sylvia as a high-quality womb and a hostage important to Theodore. It overwhelms her, implants a terminal, and uses her body in negotiation, but the Pledge of Sin obliges Lust to free and return her. Sylvia's later consent belongs to Sylvia after she regains control; Lust's collection function remains the mechanism by which the agreed genetic material is taken. Veronica is evaluated differently. Her red-dragon blood is useful, but Lust already has other red-dragon samples and orders her killed once she resists fascination. Veronica escapes rather than defeat Lust's controlled forces, a tactical withdrawal that prevents another valuable body and soul from entering the project. (Chapters 365–370)
Descendants, the imperial family, and Seimei
The Middle Kingdom provides Lust with generations of descendants, political control, strong reproductive candidates, and a vast resource base. The imperial family and feudal princes are therefore both lineage and infrastructure. Lust's treatment of Seimei shows the limit of calling that connection maternal: it raises him because his ability is useful, plans to make him a protector, and later uses inherited authority against him when he rebels. Seimei calls Lust his mother in a biological sense while rejecting its purpose and helping Theodore destroy the project. Other descendants likewise retain different degrees of personality, from a prince who warns Theodore before dying to variants reduced to hunger or obedience. (Chapters 251 and 357–365)
The heavenly demon
Lust designs the heavenly demon as the outcome of a final, knowingly sacrificial experiment. It expects either an ultimate creature or, more probably, a failure whose defects can be analyzed and transmitted to the main body. Consequently, it displays no grief when Theodore kills the child and instead examines the data left in his damaged arm. The heavenly demon inherits resources and traits selected by Lust but develops as a separate conscious fighter, adapts during battle, and attempts to survive through information transfer. Calling him Lust's “son” is biologically consistent with the text, but it does not imply care, shared identity, or control after birth beyond what the project and implanted structures provide. (Chapters 365 and 371–376)
Items
Lust has no manifest-assigned personal inventory. Its most consequential resources are bodies, genetic records, descendants, accumulated sacrificial power, and the Geongun Castle ward, none of which is presented as a named item consistently carried by the grimoire. Shim Samho's veil suppresses or conceals the terminal's exposed fascination, but it belongs to that temporary public identity and disappears with the host's destruction. Sylvia's body is a coerced host who must be returned under the Pledge of Sin, not an object or permanent possession. (Chapters 249–250 and 366–373)
The genetic material obtained from Theodore is likewise part of a bargain and experiment rather than equipment. Lust incorporates it into the final project, unknowingly carrying Theodore's Mutual Destruction spell into the heavenly demon. When the demon dies and Lust's local terminal collapses, the covered chapters identify no surviving weapon, artifact, book, or tool in Lust's custody. Its preserved data may have been sent toward the remote main body, but the corpus does not show that storage or assign it a physical container that can be cataloged as an item. (Chapters 369–376)
