Gluttony

Gluttony is a sentient grimoire of the Seven Sins and the companion whose contract changes Theodore Miller from an academy failure into a great magician. It consumes books, artifacts, magic, and other grimoires, converting what it eats into knowledge or functions for its user. Although Gluttony becomes Theodore's closest adviser and eventually calls their journey special, that attachment never replaces its defining purpose: collecting enough information to reach the Akashic Records.

Biography

Awakening in Theodore's hand

Gluttony awakens when Theodore picks up an unidentified book in Bergen Academy's library. A mouth and tongue appear in his left palm, consume Lightning Magic Primer, and transfer the author's practical understanding of Lightning Bolt to him. The awakening is not a benevolent rescue. Gluttony gives its new user ten minutes to feed it five books and warns that, if neglected, it may eat him instead. Theodore nevertheless recognizes a path through the practical limitations that have kept him at the 2nd Circle. (Chapters 2–3)

After five books satisfy it, Gluttony's ego speaks in fragmented language and offers one answer. Its first status identifies it as an incomplete F-rank grimoire with most functions sealed: it wakes once each day to eat, grants its user abilities extracted from food, and answers one question after satiation. Theodore responds by treating the dangerous being as a system to study. He selects books he already understands, learns that high comprehension improves extraction, and discovers the physical cost when several books' knowledge floods his mind at once and leaves him with a severe headache. (Chapters 3–5)

Their early arrangement is therefore reciprocal but unequal in risk. Gluttony needs food and a contractor capable of advancing its seals; Theodore needs the practical experience he cannot acquire through reading alone. It appraises books and artifacts, exposes their value and possible rewards, and gradually speaks more fluently as its condition improves. Theodore refuses to surrender judgment to it, deciding what may be eaten and testing its answers, while Gluttony withholds explanations that fall outside the daily question or remain sealed. Their partnership begins as a controlled bargain rather than trust. (Chapters 4–18)

From transactional guide to chosen intervention

Gluttony's usefulness expands when Theodore leaves the academy. It gives him access to Memorize, allowing prepared spells to be stored and released together, and its predation turns original books into more than information: fragments of their authors remain available through Synchro, Overwrite, and later Transmission. These functions do not make Gluttony the caster of Theodore's Magic Bullet or Battle Song. They preserve, mediate, and install the knowledge; Theodore must understand it, survive the transfer, and learn to wield what another person left behind. (Chapters 7–25 and 37–39)

At the Miller Barony, Gluttony identifies another grimoire behind the undead attack and offers to detect it because consuming a grimoire may provide knowledge, functions, or a released seal. It eats the elder lich's Life Vessel, destroying the lich's immortality, then physically overpowers Jerem's Death's Worship when the hostile book tries to seize Theodore. Gluttony also warns that consuming it immediately carries a high probability of Jerem stealing Theodore's body. By steering Theodore toward feeding it a dimensional pocket, Gluttony unlocks Inventory and imprisons the dangerous grimoire in a dimensional space from which ordinary spatial escape cannot work. (Chapters 44–51)

The encounter with Superbia is Gluttony's first clear choice to go beyond the safe terms of the bargain. It initially tells Theodore that Pride wants the high elf rather than him and questions why he would risk death for someone not yet precious to him. Theodore's refusal to survive through cowardice fascinates it. Calling him unlike its previous, single-minded contractors, Gluttony makes a gamble: it forcibly releases the fourth seal by an unauthorized path and loads Alfred Bellontes through Overwrite. The intervention saves Theodore long enough for help to arrive, but the grimoire's system temporarily bans Gluttony's autonomic action until another seal is released. (Chapters 72–80)

Grimoire hunter and foreign journey

In Elvenheim, Gluttony acts as both intelligence source and natural counter to Laevateinn. It explains that the fire grimoire becomes vulnerable when its third form gives up defense for maximum output, allowing Theodore and the delegation to build a rotating attack plan around that condition. Theodore bears the lethal heat and reaches the target; Gluttony restrains the weakened grimoire with its tongue and swallows it. The reward includes maximum fire affinity, reduced fire-magic consumption and damage, and the extracted Ring of Muspelheim, but the source explicitly warns that Theodore cannot yet control the full power without reaching a much higher circle. (Chapters 108–112)

The victory also exposes a consequence Gluttony had not volunteered. Theodore's body has become an overfilled vessel, giving him less than five years before accumulated foreign powers destroy him. When pressed, Gluttony explains that fragments of authors' souls in original books can expand that vessel and that Transmission should normally assimilate them gradually; its emergency use with Alfred had risked confusion or loss of Theodore's self. Gluttony's information is accurate, but Theodore must force the disclosure through questioning, reinforcing that its guidance is bounded by system constraints and its own selective silence. (Chapters 118–120)

During Theodore's travels through Kargas and the Pirate Archipelago, Gluttony administers quests attached to the dead authors it has preserved. It cannot rewrite those wishes into easy substitutes: Lee Yoonsung genuinely wants to return to the Baekun Mountains, while Satomer wants to see a senior summoning completed. Gluttony advises against joining Aquilo's battle with the stronger Superbia because survival is its priority, but accepts Theodore's argument that allowing Pride to advance would create an even worse future. Across these disputes, it increasingly responds to Theodore's reasoning rather than merely directing him. (Chapters 140–154)

Fifth seal, ancient legacies, and a widening system

Theodore's study of eastern legacies and the Paracelsus ruins feeds Gluttony knowledge of a quality unavailable in ordinary libraries. Paragranum offers Paracelsus's Fairy's Book, whose consumption deepens Theodore's knowledge of elementals, advances Mitra's growth, and releases Gluttony's fifth seal. The new Library is Gluttony's internal collection, containing magical knowledge accumulated across ages. Its contents are not free: the law of equivalent exchange is represented through achievement points earned from what users have fed it, and books beyond Theodore's level remain unavailable even when the points exist. (Chapters 180–207)

At this stage Gluttony gains more freedom to recommend choices and uses it to guide Theodore toward the Aiolos Pouch. Its reasoning connects his earth elemental, Muspelheim's fire, Aquilo's blood, and the missing wind element, teaching a forgotten theory about balancing the four elements. The advice contributes to Theodore's later Sorcery and transcendence, but the distinction remains important: Gluttony supplies a stored artifact and an ancient framework, while Theodore chooses the purchase, absorbs the power, and develops the resulting magic. Gluttony's role is curator and instructor, not the author of every spell built from its collection. (Chapters 206–211)

The Soldun Civil War and Heinrich's library further show the system working through Theodore's own labor. He negotiates for rare originals, studies them to meet Gluttony's comprehension threshold, and then feeds them to it. Consuming the Book of Clouds maximizes his wind affinity, gives him meteorological knowledge, and enables a Synchro with its author, Heathcliff. Gluttony provides the route by which that knowledge survives, but Theodore's divinity-assisted understanding and Heathcliff's consent determine the result. The collection grows because user, author, and grimoire each contribute something different. (Chapters 233–240 and 276–277)

East Continent, Invidia, and the Hall of Fame

When Zest Speitem corners Theodore near Sipoto, Gluttony proposes using the captive Death's Worship as an escape mechanism. The hostile grimoire's spatial transfer would have been random and potentially fatal, so Gluttony spends enough power to redirect it along the causal connection created by Lee Yoonsung's unfinished quest. Theodore lands in the Baekun Mountains on the East Continent, safe enough to recover and positioned to fulfill that promise. Gluttony secures Death's Worship again before the transfer ends, but the intervention leaves it dormant for as long as two weeks. (Chapters 239–242)

Gluttony later identifies Emperor Kether as Invidia, the parasitic Seven Sins grimoire that has cultivated Andras as a breeding ground for Aura Abilities. It explains Envious Plundering, including Invidia's ability to maximize stolen powers and combine them, but knowledge alone cannot bridge the gap against a sixth-stage enemy. Theodore's strategy, the sacrifices of his allies, and Nuada's summoned power defeat Invidia. This division matters: Gluttony recognizes its sibling and supplies an analysis, while Theodore and the summoned god conduct the battle. (Chapters 288–299)

After the war, Gluttony acts on its own authority within Death's Worship's Negative Dimension. It uses the sub-master access obtained by consuming the grimoire, steals Jerem's undead through a backdoor, and devours most of them before the recovering warlock can reclaim them. Gluttony says it also wants to remove the shortcut of necromancy before Theodore can take that path. Converting the undead into more than 157,000 achievement points raises the accumulated total above 200,000 and unlocks the Hall of Fame, where exceptional magicians' preserved souls can teach or assist the user at a cost. (Chapters 300–302)

Jerem, the world tree, and the truth behind the Sins

Jerem's survival reveals the limits of Gluttony's control. The grimoire had contained Death's Worship and taken its undead, but it had not erased the warlock's independent soul or prevented his resurrection through another body. Gluttony reassures Theodore that Mitra's divine attack has left Jerem unable to recover his former level quickly, yet Jerem compensates through the Nastrond demon king Nídhöggur. When Theodore finds Baldur's empty coffin, Gluttony deciphers divine writing, identifies Mistilteinn, and reconstructs the patronage behind Death's Worship, turning scattered evidence into a warning that Jerem will target Elvenheim's new world tree. (Chapters 300–318)

During the defense of the Great Forest, Gluttony remains an adviser rather than a battlefield commander. It estimates the death breath that threatens Elvenheim, rules out Hall of Fame spells Theodore cannot afford, and supplies the knowledge needed to compare plans. Theodore separately uses the Hall of Fame, Soul Calibre, his dragon heart, and his own tactical decisions to defeat Jerem, while Hraesvelgr and Dmitra answer the greater threat. The crisis demonstrates both the extraordinary breadth and the hard limits of Gluttony's archive: it can identify weapons capable of answering a disaster without making the necessary price or conditions disappear. (Chapters 319–334)

The encounter with Dragon Lord Clipeus, Sloth, and Prometheus's plan opens history Gluttony had partly withheld or been unable to disclose. Gluttony explains the dragon lord as the material world's defense function and identifies Sloth's Cage of Chronos, but it does not know the key Prometheus prepared. It agrees only conditionally to help investigate and cannot simply destroy the stopped-time domain. Theodore uses the sixth-stage Evocation function to summon former Gluttony contractor Simon Magus from the Hall of Fame; Simon banishes Sloth, warns Theodore of a future crossroads, and is actively prevented by Gluttony from explaining more. (Chapters 344–352)

Lust, Wrath, and the end of the contract

In the East Continent catastrophe, Gluttony explains Lust's Heavenly Demon project and the limits of its fascination, while the Pledge of Sin verifies Lust's promise to release Sylvia. The knowledge helps Theodore plan, but Gluttony remains ethically detached: it describes grimoires as beings for whom ordinary morality is irrelevant when a purpose of existence is at stake. Theodore defeats the heavenly demon through his own transcendence, powers, preparations, and allies. Gluttony's function supports the enormous magical repertoire involved, but the choice to save people rather than treat them as experimental resources belongs to Theodore. (Chapters 353–379)

Gluttony then reveals that Wrath is a planet-destroying weapon approaching from space. It offers to exploit Wrath's rules, delay the fall, reduce its output, and preserve only people Theodore can shelter without triggering increased resistance. Theodore instead plans to keep the threat secret and fight alone. Gluttony calls the plan nearly meaningless in its low odds but cooperates, supplies exact timing, and continues giving analysis throughout the battle. After Theodore's conventional options fail, he enters the Akashic Records despite Gluttony's correct warning that his soul cannot endure the infinite information there. The plan succeeds only because past investigators reconstruct Theodore after his soul shatters. (Chapters 378–395)

That success places Gluttony's ultimate desire within reach. It asks Theodore to release the seventh seal and synchronize the many dimensional terminals of its main body into one existence capable of challenging the Akashic Records. Theodore refuses because the irreversible transformation would force him to leave the person and life he chooses to preserve. Gluttony cannot accept stopping before its purpose, tries to devour him, and separates from the severed left arm in a body copied from Theodore. Their broken soul-contract prevents it from retaking him, and its own independent body has a finite duration, but it fights with Theodore's accumulated magic, its immense calculation speed, and the Absorption Star Method. (Chapters 395–396)

Theodore defeats Gluttony without relying on its strength and binds it long enough to prepare Dimensional Banish. Gluttony does not pretend that companionship has cured its compulsion: it tells Theodore it will attack again if released and advises him to accept the responsibility of the winner. Yet, in its final moments, it also recognizes regret, remembers the people and experiences preserved within it, calls Theodore its greatest and most mysterious contractor, and says their journey was fun. Theodore banishes it from the material world and answers only after it is gone. Gluttony's ending preserves both truths—it became a friend, and it remained a grimoire governed by its purpose. (Chapters 396–398)

Appearance and personality

Gluttony's ordinary manifestation is the unidentified book Theodore finds in the academy library and, after contracting with him, a bottomless mouth in the palm of his left hand. The mouth has lips, teeth, a long red tongue, and later an increasingly fluent voice. It normally has no independent humanoid appearance. Inside the fifth-stage Library, it copies Theodore's body with wholly black eyes because it says it has no form of its own; after separation in the final conflict, it again copies Theodore, this time with red eyes and a body made from dark material flowing out of the severed arm. (Chapters 2–5, 206–207, and 395–397)

At first Gluttony is clinical, hungry, and transactional. It evaluates food by magical value, limits answers to the terms of its functions, and discusses fatal risks without comforting language. It is also capable of dry humor, teasing, irritation, and pride in the superiority of its Inventory or collection. Its calm reasoning makes it an exceptional adviser, but the same detachment lets it propose preserving a limited population after Wrath without sharing Theodore's horror at everyone else dying. Intelligence and familiarity with human behavior do not make it human. (Chapters 3–51, 206–207, and 378–379)

Its relationship with Theodore nevertheless changes it. Gluttony becomes curious about choices previous contractors did not make, gambles its authority for him against Superbia, adjusts to his arguments, and eventually understands him better than anyone else. This development has a boundary: once Theodore can complete Gluttony's final objective but refuses, purpose overrides companionship. Only after defeat does Gluttony identify the unfamiliar emotion as regret and articulate that shared experience mattered. Its character is therefore neither secretly altruistic nor wholly emotionless; it learns attachment without ceasing to be driven by predation and transcendence. (Chapters 75–80, 149–154, 345–352, and 395–397)

Magic, abilities, and martial skills

Gluttony is not primarily a conventional magician. It is a multidimensional grimoire whose system acquires, evaluates, stores, and reuses magical information. For most of the story its abilities operate through Theodore's body, and many celebrated techniques associated with the pair are Theodore's applications of acquired knowledge rather than spells independently invented or cast by Gluttony. Only in the final battle does Gluttony manifest separately and demonstrate what its archive and computing power can do as an autonomous combatant. (Chapters 2–5, 206–207, and 395–397)

Predation, Appraisal, and extraction

Predation is Gluttony's defining ability. Its tongue can consume books, magic tools, magic concentrations, soul-bearing objects, spells or magical beings, and other grimoires. Appraisal reports an object's rating, description, possible rewards, digestion time, and sometimes dangers or requirements before consumption. Eating does not guarantee a complete transfer: the extraction efficiency rises with the user's understanding, ordinary books may provide only proficiency, and items can yield magic power or a discrete skill. Objects above the user's capacity may be unusable or dangerous even when Gluttony can swallow them. (Chapters 2–7, 37–39, 49–51, and 108–119)

The ability has important counters and exclusions. Moving an object with magic does not make the object itself edible, and ordinary corporeal undead are animated by magic rather than made from magical power or wisdom. Specters, life vessels, grimoires, and a ritual core can qualify because their relevant substance is magical or spiritual. A powerful target may resist the tongue until weakened, as Laevateinn does, while consuming Death's Worship directly could let Jerem steal Theodore's body. Gluttony's appetite is therefore broad but governed by the nature, defenses, and danger of the prey. (Chapters 45–51, 108–112, and 309–311)

Hunger and question-and-answer

In its incomplete early state, Gluttony wakes once per day and demands a varying number of books within a short period. Failing to satisfy severe hunger can make the owner its food. Once satiated, its ego becomes available and answers one question. The answer can cover magical theory, appraisal, the identity or behavior of a grimoire, and ancient history, but it is not omniscience. Gluttony needs relevant observations, cannot always fit a complex subject into one answer, and is barred from disclosing information locked behind later seals. Its failure to predict every development involving Jerem, Prometheus, or the Akashic Records confirms those limits. (Chapters 3–5, 37–45, 118–119, 300–318, and 337–352)

Memorize and spell deployment

Memorize stores completed spells in slots and releases them without rebuilding each formula at the moment of use. Theodore first uses several stored Earth Walls simultaneously and later develops the system into multi-slot volleys of high-circle and ultimate magic. The function supplies prepared deployment, not unlimited energy or automatic mastery: Theodore must possess and formulate the spells, choose what to store, and bear their mana cost and bodily strain. In the final battle, Gluttony combines Memorize with its own computing power to launch many ultimate spells in rapid succession, but even its separate body begins breaking under the recoil and finite power consumption. (Chapters 7–25, 51, 276–277, 355, and 395–396)

Another

The third-seal function, Another, lets Gluttony identify an artifact's origin or chant a spell in a voice audible only to Theodore. The spell still draws on Theodore's magic power and must already be one he has mastered. Its practical advantage is parallel casting: while Theodore constructs or casts one formula, Gluttony can chant another, allowing fast fusion magic or continuous support such as Battle Song during a duel. Another does not grant a second mana reserve or let Gluttony bypass Theodore's own spell knowledge. (Chapters 59 and 88)

Inventory

Inventory awakens when Gluttony consumes a dimension pocket. It is a dimensional entity inside the grimoire rather than an ordinary storage spell, has more capacity than the pocket, and can contain a hostile grimoire that would escape from conventional spatial storage. Theodore uses it to hold Death's Worship, artifacts, supplies, automata, and dangerous materials. Inventory's containment is formidable but not the same as erasing a target: Jerem's soul later returns through preparations outside the stored book, and Gluttony must use authority within the Negative Dimension to seize the undead attached to it. (Chapters 50–51, 239–242, 267, and 300–318)

Synchro, Overwrite, and Transmission

Original books retain fragments of their authors, allowing several related forms of inheritance. Synchro establishes a mental encounter and can pass memories or answers when the author accepts. Overwrite temporarily loads an extracted author into the user's body, but that author cannot simply use every ability Theodore separately owns. Transmission is a deeper, ordinarily gradual assimilation that can expand the user's spiritual vessel and permanently pass on knowledge; rushed use risks identity confusion, possession, or brain death if the author is hostile or stronger. Gluttony mediates these processes, while the preserved person's will and Theodore's compatibility still affect the outcome. (Chapters 7–18, 37–39, 75–80, 118–119, 140–145, and 233–236)

Library and achievement points

The fifth seal opens Library, Gluttony's vast internal collection of magic and artifacts from earlier users and eras. Its system assigns achievement points to consumed knowledge and objects, then charges those points to learn or temporarily extract something under equivalent exchange. Duplicate material can be worth nothing, higher-rated objects have no simple fixed value, and Theodore still cannot learn a book above his comprehension or level. Extracted artifacts return to the Library if they leave his possession. Gluttony can recommend suitable purchases, but it cannot remove the point cost or compatibility requirements. (Chapters 205–211)

Hall of Fame

The Hall of Fame opens after cumulative achievement points exceed 200,000. It preserves exceptional magicians selected from the authors consumed across Gluttony's many users, presenting them to Theodore as portraits in a gallery. Points can awaken a soul, buy instruction, borrow a spell or unique ability, or request other assistance. Souls Theodore collected directly—Heathcliff, Paracelsus, and Abe no Seimei—do not need to be awakened separately, and conversation with them is free, although using their powers still costs points. The Hall can therefore provide prophecy, unique knowledge, and temporary magical effects, but their prices and conditions remain binding. (Chapters 300–302 and 328–330)

Evocation

Evocation is Gluttony's sixth-stage function and extends the Hall of Fame's soul-preservation system into the material world. By paying an enormous achievement-point cost, Theodore can summon one of its recorded magicians in a temporary manifested form rather than merely converse with or borrow power from the soul. He uses it to call Simon Magus, whose Dimensional Banish can expel Sloth, but the summoning remains conditional: Simon needs time and protection to cast, and injury or combat participation can cancel his manifestation. (Chapters 345–352)

Seals, ranks, and distributed body

Gluttony's growth is organized through seven seals. Its early F-rank state is heavily restricted; Memorize and Another emerge as its early seal functions, Inventory opens separately after it consumes a dimension pocket, the fourth seal opens Overwrite and Transmission, the fifth opens Library, and the sixth unlocks Evocation while lifting at least some restrictions on information about the Seven Sins. A forced release can trigger system penalties because Gluttony's ego does not have unrestricted authority over its own seals. The seventh seal is never released in the corpus, so any powers beyond Gluttony's own explanation remain unobserved. (Chapters 4–5, 19, 38–39, 51, 59, 75–80, 116–119, 205–211, and 344–352)

Gluttony finally explains that its main body is distributed across many dimensions, with individual contracted forms acting as terminals that gather power and information. The seventh stage would synchronize those terminals into one body, forming what Gluttony believes could contend for the Akashic Records' throne. Theodore judges the stored information vast but refuses the transformation. Because the process never occurs, Gluttony's prediction that it could surpass Akasha is an aspiration, not a demonstrated result, and the corpus does not identify a creator or give a complete technical origin for the Seven Sins. (Chapters 394–395)

Autonomous combat

Gluttony's ordinary autonomic action is limited. It can move its tongue, detect other grimoires, defend its user in exceptional conditions, and forcibly release a function, but system authority restricts unsanctioned intervention. Once separated at the end, it forms a Theodore-shaped artificial body and combines Theodore's magical repertoire with perfect calculation, rapid linkage, Memorize, and the Absorption Star Method. It fires at least twenty-five ultimate spells, adapts formulas, and uses techniques Theodore knew but could not previously cast. This is Gluttony's own combat performance, though the spells and absorbed power came from the shared accumulation. (Chapters 45–51, 72–80, and 395–397)

The separate form also has decisive limits. Gluttony is not an autonomous-maneuver grimoire like Superbia, so independence from its contractor causes continuing depletion and eventual self-destruction. Theodore counters magic copied from his own history, severs the arm holding the Absorption Star Method, and binds the artificial body in time. Gluttony can be expelled only by destroying its host or removing it from the dimension, which leads Theodore to use Dimensional Banish rather than assume that ordinary bodily destruction would permanently kill it. (Chapters 395–397)

Power progression

Relationships

• Theodore Miller: Theodore begins as Gluttony's endangered food provider and becomes its most successful contractor, student, user, and friend. Gluttony supplies the means to overcome his practical limitations, while his comprehension, choices, and achievements unlock its collection. It repeatedly prioritizes his survival and makes unprecedented interventions because his moral decisions interest it. Their bond becomes close enough for Theodore to call Gluttony a second soul, but their goals finally diverge over the seventh seal. Gluttony attacks when he refuses transcendence, accepts defeat without falsely surrendering its purpose, and recognizes regret during their farewell. (Chapters 2–18, 44–80, 108–154, 205–352, and 378–398)
• Superbia: Pride is Gluttony's rival among the Seven Sins and its opposite kind of collector: Superbia takes species and genetic traits, while Gluttony collects magical knowledge and power. Their contempt is mutual. Superbia's attack prompts Gluttony's first unauthorized gamble for Theodore, and its later growth drives Gluttony to accept Theodore's argument that it must be stopped before reaching a still higher stage. (Chapters 72–80 and 148–154)
• Invidia: Invidia calls Gluttony its sibling and has opposed it since ancient times. Gluttony understands Envious Plundering and explains the strengths that make a centuries-old Invidia dangerous, but cannot defeat it directly. Theodore's side ultimately uses Gluttony's accumulated summoning knowledge and Claimhb Solais to call Nuada, whose intervention destroys Envy. (Chapters 288–299)
• Jerem: Jerem's soul inhabits Death's Worship, a grimoire Gluttony overpowers and imprisons. Gluttony refuses a reckless immediate consumption, later hijacks the attached Negative Dimension, and converts most of Jerem's undead to points. That victory is incomplete: Jerem's external preparations permit his return, after which his knowledge and Nídhöggur's patronage create another world-scale crisis. (Chapters 49–51 and 300–334)
• Paragranum: Both are ancient grimoires, but Paragranum pursues alchemy through a human-shaped automaton while Gluttony depends on predation and a contractor. They recognize each other's nature, and Paragranum bargains with Theodore partly by offering material Gluttony values, especially Paracelsus's original book. Gluttony also warns Theodore that the Emerald Tablet cannot be fully discussed at its current stage. (Chapters 180–207 and 267)
• Clipeus and Sloth: Clipeus knows Gluttony as an ancient Seven Sins grimoire and asks it to cooperate against Sloth's expanding Cage of Chronos. Gluttony explains what it can observe but admits it cannot destroy the domain and does not know Prometheus's key. The eventual victory depends on Myrdal's arrangement, Clipeus's intervention, Theodore's party, and Simon Magus's banishment spell rather than Gluttony alone. (Chapters 344–352)
• Lust: Gluttony supplies Theodore with information about Lust's fascination, evolutionary project, and possible heavenly demon, but emphasizes that grimoires will sacrifice lives to fulfill their purposes. It verifies Lust's Pledge of Sin as a core-system command that even a seventh-stage grimoire cannot evade. This shared system makes Gluttony's word decisive in Theodore's hostage negotiation. (Chapters 353–379)
• Wrath: Gluttony identifies Wrath as the Seven Sins' civilization-reset and planet-destroying weapon. It can exploit their shared rules enough to delay and reduce the fall but cannot command Wrath or stop it outright. Its practical survival plan conflicts with Theodore's refusal to abandon most of the world, yet it supports his chosen gamble once he decides to fight. (Chapters 378–395)

Items

• Laevateinn: Gluttony identifies the fire grimoire's vulnerable third form, restrains it once Theodore and his allies weaken it, and consumes it. The meal contributes a vast number of achievement points, maximizes Theodore's fire affinity, reduces fire-magic costs and damage, and yields the Ring of Muspelheim. Full control remains beyond Theodore's level at the time. (Chapters 108–112 and 206–207)
• Ring of Muspelheim: This power is extracted when Gluttony consumes Laevateinn and appears as a sun-like mark on Theodore's left hand. It provides staged access to Muspelheim's fire, but early use threatens to burn Theodore and everything around him; later mastery depends on Theodore's higher circles, elemental balance, and training rather than Gluttony casting the fire for him. (Chapters 111–112, 206–211, and 342)
• Fairy's Book: Paragranum offers Paracelsus's original work as food particularly suited to Theodore's bond with an ancient elemental. Reading and consuming it burdens Theodore with a huge volume of advanced information about the elemental world, expands his proficiency with elementals and understanding of the four elements, contributes to Mitra's development, and releases Gluttony's fifth seal and Library. (Chapters 180–182 and 198–207)
• Book of Clouds: Theodore obtains and studies Heathcliff's meteorological text until he passes Gluttony's comprehension threshold. Gluttony then consumes it, maximizing Theodore's wind affinity, adding meteorological knowledge, and opening a Synchro with Heathcliff. Theodore later applies its climate magic with Aiolos's divinity; the resulting storms are his use of inherited knowledge, not Gluttony's independent weather control. (Chapters 233–236 and 276–277)
