Abilities

Card Crafting

Dekan's primary ability is his exceptional card-crafting skill, which he has honed since childhood. He consistently creates cards far above his tier, with a talent for designing unique and unusual effects. His crafting relies on a deep understanding of magical languages, including Demonic script, and the ability to combine principles from different card types. He often works in a focused, almost trance-like state, and can collaborate with Talomati to produce cards of even higher quality. Dekan's cards frequently incorporate curse properties, mental-type effects, pain feedback, and forbidden magic, leading to distinctive and unpredictable outcomes.

• Applications:

  • Crafts Blue Rare cards at Tier 2, such as [Hydrogen Explosion] and [Goblin Sheriff], surprising even experienced crafters 1 2.
  • Creates Orange Epic cards at Tier 3, notably [Blood Purification], which appraises as an exceptional-quality card 45.
  • Develops a Tier 3 mental-type spell card, [Three-Corpse Berserk], which amplifies the desires of all within range 84.
  • Uses Demonic script to program additional effects into cards, such as active damage reflection on a Cursed Puppet 205.
  • Collaborates with Talomati to create complex cards such as [Three-Corpse Berserk] and the Crimson Epic curse-based Equipment Card [Dekan Gospel] 84 187.
  • Produces large quantities of [Captain Dekan] cards, demonstrating both his technical consistency and ability to industrialize a signature card design 100 187.
  • Uses Cat Teacher as a portable storage unit to bring a complete Underworld card-making toolkit and seized cards through Baleful Intentdow Worlds 86.
  • Applies practical knowledge of Magitech Engineering, medicine, and pharmacy to repair magical apparatus, modify equipment, and develop antidotes 27 48 445.
  • Researches and maintains the [Spatial Leap Gate] with Mie and later works with Talomati to produce a powerful curse-magic scroll that he cannot yet convert into a Magic Card 383 392.

• Limitations:

  • Card creation is resource-intensive; crafting a single high-tier Epic card spent most of his savings 187.
  • High-risk processes can be dangerous; his failed attempt at a Red Legend card could have resulted in an explosion 187.
  • Requires specialized materials, often needing the help of influential figures like President Leren to acquire fourth-tier Epic Demon-type materials 187.
  • His cards are highly distinctive and easily linked to him, making him a target for those who want his creations or fear his potential 45 125.
  • Some of his cards, especially mental-type spells, can affect allies if not used carefully, as seen with Cat Teacher and Cornelia’s reactions to [Three-Corpse Berserk] 84.
  • Certain advanced spells remain beyond his ability to make into cards, forcing him to rely on alternative mediums such as magic scrolls 392.

Strategic Mind

Dekan is a highly strategic thinker, known for his meticulous preparation and ability to exploit rules and opponent tactics. He studies his enemies in advance and designs countermeasures, often using unconventional methods to gain an advantage. His planning extends to manipulating duels, using his environment, establishing false identities, and setting traps.

• Applications:

  • Anticipates Flata's strategy in a duel, equipping Undead War Armors with Cursed Soul Masks to prevent de-summoning and double their mana consumption 63.
  • Uses the [Temptation of the Living World] spell to double mana consumption for both sides within a 100-meter radius, forcing a high-tier opponent into an unfavourable exchange 63.
  • Hypnotizes himself before entering a Baleful Intentdow World to seize the Witch identity and gain the Rebel Challenger qualification 84.
  • Sets a trap for Viscount Augustine by placing the poisoned body of the Assassin Sister near the Hexagram Array and using [Three-Corpse Berserk] to ensure he drinks it 84.
  • Exploits the rules of a Bishop Duel by granting his Caster Croix the Summon attribute via [Demon Curse Seal], allowing Croix to intervene without violating the duel's terms 216.
  • Plans to use his newly crafted Epic card for a “massive reckoning” against enemies in the Kingdom Association, leveraging its curse principles 186 187.
  • Infiltrates Resurrection Church Bishop meetings with stolen Bishop’s Tokens, disrupts their communications, and develops a private information channel with Minos 147.
  • Impersonates Bishop of Frenzy Clay through Clay’s Bishop’s Token to gather intelligence and manipulate Church relationships 208.
  • Bluffs Carster into believing that a vengeful Devil King has possessed him, using the deception to force Carster to uncover Devil King Tombstones 279 280.
  • Coerces the Void Gate by threatening to overload it with challengers, then offers natural Magic Cards as leverage to make it accept his demands 406.

• Limitations:

  • His strategies often rely on specific card effects and materials, which can be costly or difficult to acquire 187.
  • Over-preparation can lead to complications, such as being locked in his workshop for two weeks 186.
  • His unconventional tactics can unsettle allies and draw unwanted attention from authorities 97 112.
  • The effectiveness of his plans can be undermined if opponents possess counters to his specific cards, as seen with Flata's initial wariness 63.
  • His tricks are less reliable when repeated; experienced opponents can prepare cards such as [Pain Shield], [Berserk], and purification effects specifically to counter his established systems 299 306.

Combat Prowess

Although primarily a card crafter and strategist, Dekan is also a capable combatant, often using his custom-built deck to overcome stronger opponents. He relies on a mix of offensive spells, defensive equipment, summon cards, and psychological effects. His combat style is resourceful and efficient, aiming to end fights quickly or make a direct confrontation prohibitively costly for the enemy.

• Applications:

  • Clears the Baleful Intentdow World entrance exam in 57 seconds using his Epic soul card [Ruined Poet], inflicting intense pain feedback on Professor Arnold 7.
  • Uses [Three-Corpse Berserk] to amplify a vampire's bloodlust, ensuring he drinks poisoned blood and becomes manageable 84.
  • Uses the [Ice Encasement] spell card to protect himself from high-tier summoned creatures 63.
  • Equips and manipulates enemy summons with Cursed Soul Masks to turn their upkeep costs against their masters 63.
  • Defeats the demon Carster on the Eighth Floor after mastering the Bishop of Falsehood's abilities 282.
  • Uses the Devil King’s magic power to break the Saintess of Darkness’s seal and rescue her 282.
  • Fights Bishop of Corruption Fahim through a combination of attrition, rule exploitation, Croix’s support, and pain-feedback equipment 216 217.
  • Uses [Excel] to decisively outperform Altis in Imperial Arithmetic, finishing an objective examination in six minutes and fifty seconds 251.
  • Uses card-disarm combinations, [Solar Fist], [Swift Mole], and carefully preserved hidden cards to compete against higher-tier Hero Festival opponents 306.

• Limitations:

  • His mana reserves and soul-binding capacity are limited by his rank; at Tier 2 he could only carry a combined rank of 20 in cards 7.
  • Low rank relative to his enemies is a fatal weakness; he can be counter-built against by a professional melee system, as Isabel did with mage-counter cards 125.
  • His most powerful cards are resource-intensive and must be used sparingly 2 63.
  • Self-use of his mental-type cards can affect his friends, as Cornelia struggled with self-control under [Three-Corpse Berserk] 84.
  • His reliance on unconventional cards means he can be vulnerable if his deck is compromised or if an opponent has specific countermeasures 125.
  • Dekan openly acknowledges that he cannot defeat Bishops or seventh- and eighth-tier specialists in a straightforward fight and must instead depend on preparation, allies, and one-use schemes 210 222.

Devil King Authority

During the Tier 7 Baleful Intentdow World, Dekan gains access to a limited portion of Devil King authority. This power is connected to the Devil King Tomb, the Devil King Mark, and Master’s fragmented memories. While it initially functions as a situational advantage on the Eighth Floor, it later becomes central to his work within the Devil King Tomb and his ability to confront increasingly extraordinary entities.

• Applications:

  • Learns the Devil King Mark’s function of imprinting will or soul onto objects after Master reconstructs a spell formation from a tombstone 278.
  • Cooperates with Master to control their shared body and overcome Carster’s illusion barrier 278.
  • Gains enough authority over the Eighth Floor’s Devil King mana to defeat Carster and free the Saintess of Darkness 282.
  • Uses his assumed Devil King status to intimidate Carster into assisting with the excavation of Devil King tombstones 279 280.
  • Exercises authority over the Devil King Tomb while researching its ancient card-making tools and pursuing its mission objectives 386 388.
  • Imprisons Chaos Gods in the Devil King Tomb and uses the [Spatial Leap Gate] to display their captivity to Apotos 425.

• Limitations:

  • His initial authority is limited to the Eighth Floor and depends on the Devil King Tomb’s unique conditions 282.
  • Master’s memories are fragmented, restricting the amount of reliable historical knowledge Dekan can obtain from her 274 278.
  • The Tomb’s objectives require sustained technical work and cooperation from Eve rather than brute force alone 386 388.

Soul-Binding and Deck Composition

Dekan's soul-binding ability allows him to carry a limited number of cards whose total tier cannot exceed his own rank-based capacity, such as 20 at Tier 2 and 30 at Tier 3. He typically carries a small number of high-quality cards rather than filling his slots with many low-tier cards. This approach emphasizes quality and synergy over quantity.

• Applications:

  • Binds only three cards for his entrance exam, using [Ruined Poet] as his main weapon despite carrying fewer cards than the maximum 7.
  • Selects cards that complement each other, such as using [Demonic Curse Seal] to enable Croix's intervention in a Bishop Duel 216.
  • Uses Cat Teacher as an external storage unit to bring a full set of Underworld tools into the Baleful Intentdow World without occupying his own card slots 86.
  • Prepares multiple specialized cards for different situations, such as [Three-Corpse Berserk] for mental manipulation and [Solar Fist] for combat 84.
  • Binds his newly crafted Epic Equipment Card to his soul, intending to conceal it and use it only when necessary 187.
  • Rotates cards and preserves hidden systems for tournament combat, knowing that familiar pain-feedback tactics are increasingly easy for strong opponents to counter 299 306.

• Limitations:

  • The limited number of soul-bound cards restricts the variety of tactics he can employ in a single encounter 7.
  • Binding high-tier cards consumes a large portion of his soul capacity, leaving fewer slots for other utilities 2 7.
  • If his soul-bound cards are destroyed or sealed, his combat capability is severely reduced 125.
  • Some powerful cards come with side effects that require careful management, such as the potential for dangerous side effects in his Ultimate Happy Card 187.

Disguise and Identity Manipulation

Dekan repeatedly uses appearances, false identities, and social performance as practical tools. His disguises range from transformation cards and masks to carefully constructed public personas, allowing him to infiltrate hostile groups and redirect suspicion.

• Applications:

  • Uses Cat Teacher’s transformation card to assume the form of a Sprite Cat for infiltration and concealment 59.
  • Adopts priestly attire to blend into the Holy Rite Church and uses the Red Center Mask when entering areas where old enemies may recognize him 154 228.
  • Disguises himself as a succubus jailer in Demon Prison, using his jailer status to travel between floors and locate his allies 224 228.
  • Performs the role of a Devil King-possessed jailer to deceive Carster 279.
  • Maintains a public image as a righteous, patriotic, and law-abiding student while covertly acting against the Resurrection Church and Kingdom Association figures 132 222.
  • Adopts a frightened-girl persona to infiltrate the imperial army without exposing his signature cards or identity 360.

• Limitations:

  • Dekan’s distinctive curse cards and public notoriety make it difficult to remain anonymous for long 186 360.
  • Enemies who understand his established card systems can identify him even when his appearance is concealed 100 306.
  • His public association with the Resurrection Church, the Bishop of Pain, and the Lord of Calamity repeatedly threatens to undermine his carefully maintained reputation 151 221 309.

Personality

Dekan possesses a deeply contradictory and multifaceted personality, blending genuine compassion and humility with ruthless cunning and strategic manipulation. He is capable of great kindness—showing empathy toward a suffering human scholar 225 and publicly defending a bullied friend 60—yet equally willing to employ torture, psychological terror, and dirty tricks to achieve his objectives 20 109 222. He is a meticulous planner who values hard work and dedication 8 27, but he is also an opportunist who exploits loopholes, bluffs, and underhanded tactics 77 279. Dekan is acutely aware of his public image, often maintaining a noble and righteous persona to earn trust or avoid suspicion 222 224, while privately embracing his unscrupulous side. He is fiercely loyal to his allies, taking on increased burdens to protect them 27, yet can be cruel and humiliating toward enemies or those who cross him 20 134. Underlying this complexity is a pragmatic, calculating mind that weighs moral costs against desired outcomes, often choosing the most effective route regardless of conventional ethics.

• Compassionate and Empathetic: Despite his darker tendencies, Dekan shows genuine care for the vulnerable. In Demon Prison, he feels distress watching a human scholar tortured and uses his Pain Reflection set to attack the cruel jailer Lars, reliving the scholar’s pain to trigger the bracelet’s judgment 225. He also empathizes with socially anxious individuals, though he finds them frustrating 252. In later life, he patiently teaches children and church personnel how to make simple antidotes 445.

• Strategic and Manipulative: Dekan excels at psychological manipulation, exploiting fears and perceptions. He bluffs Carster into believing he is possessed by a Devil King to secure his cooperation 279. During the Gam Interrogation, he uses deception and knowledge of the cultist’s fears to extract a confession 109. He also manipulates prison rules and noble demons to turn their harassment against them 236. His infiltration of Bishop meetings and impersonation of Clay further demonstrate his ability to weaponize information and identity 147 208.

• Ruthless and Cruel: When necessary, Dekan does not shy away from inflicting extreme suffering. He poisons Baron Batchelor, summons the Ruined Poet to torture him, and has Cornelia amplify the pain with a Terror Warhammer 20. He humiliates Isabel by making her act like a dog and plans to use her to confront the Bishop of Ruin 134. He curses Laxas VI twice in a day, causing him distress and rage, and ultimately orchestrates the king’s prolonged torture and death 193 220. He later imprisons Chaos Gods in the Devil King Tomb without showing mercy 425.

• Dedicated and Hardworking: Dekan is committed to self-improvement, practicing finger dexterity for card crafting every morning and studying detoxification and curse-breaking at the library 8. He repairs the school’s broadcasting room with Cornelia to gain control over class-start music, demonstrating engineering skill and strategic effort 27. He also spends long periods conducting difficult research in the Devil King Tomb rather than treating its objectives as mere entertainment 386 388.

• Noble Facade and Moral Posturing: Dekan consciously performs a virtuous persona when it benefits him. He presents himself as a righteous patriot to gain Alice’s trust, declaring that defending the kingdom’s glory is a bounden duty 222. He reminds himself to be “gentle, kind, respectful, frugal, and yielding” to avoid being linked to the Lord of Calamity 224. However, he internally acknowledges his willingness to use every dirty trick available 222.

• Loyal and Protective: Dekan stands up for his friends without hesitation. He publicly supports Croix against Flata’s bullying, inviting Croix to his team and hinting at consequences for Flata 60. When a teammate’s disguise is exposed, he accepts the increased workload without complaint 27. He also shows concern for Cornelia’s well-being during stressful situations 126, remains troubled when he believes he has made her cry, and apologizes even when he does not fully understand what he did wrong 411.

• Playful and Sarcastic: Dekan often uses humor and sarcasm, especially with close companions. He taunts his card pirate Tata and then retorts playfully when rebuked by Master 200. He bickers with Cat Teacher, calling its cowardice into question 77. He also sarcastically thanks Master for intel, then quickly apologizes when caught 154.

• Resilient and Resourceful: Even when outmatched, Dekan remains calm and searches for counters. Against Isabel, he repeatedly tries different tactics despite her superior tier and strategy 126. In the Knight Academy exam, he uses his Epic Magic Card to defeat Professor Arnold in 57 seconds, achieving an SSS rank 7. He continues competing against opponents far stronger than himself during the Hero Festival by preserving hidden systems and exploiting every available opening 299 306.

• Unconventional and Outrageous: Dekan defies traditional expectations. He scores a perfect written exam but shows poor physical attributes, leading Professor Arnold to call him “outrageous” 5. He reads the rulebook for the Hero Festival not for virtuous compliance but to find loopholes 222. His philosophy of the Knight Academy curriculum focuses on practical tricks rather than conventional combat 4.

• Pragmatic and Amoral: Dekan’s morality is flexible, driven by utility. He considers “the unscrupulous Dekan” an existence beyond the norm 222. He decides to clear the Demon Prison floor in a way that accumulates “boundless merit” largely to protect his reputation 224. He is willing to use emotional states to trigger magical effects for strategic gain 225. His coercion of the Void Gate and containment of Chaos Gods demonstrate that this pragmatism persists even after his power grows dramatically 406 425.

• Frustrated by Certain Personalities: Dekan is annoyed by people who are socially anxious yet appear cold and arrogant, as they remind him of the Ice Princess who caused him trouble 252. He also finds it difficult to handle individuals who cry easily, as it makes him look like a bully 252.

Relationships

Cornelia

Dekan and Cornelia’s relationship evolves from cautious mutual curiosity into a tightly knit partnership built on trust, complementary skills, and silent understanding. Initially, their bond is forged through necessity: Cornelia struggles with language barriers and mathematics, while Dekan’s fragile body makes him wary of her immense physical strength. Over time, they become each other’s most trusted ally—Cornelia providing protection and brute force, Dekan offering strategic guidance and academic support. Their dynamic is marked by non-verbal communication, shared mischief in subverting school authority, and a growing willingness to rely on one another in life-or-death situations. Dekan consistently prioritizes her safety, and Cornelia’s loyalty never wavers, whether in Demon Academy exams, against the Resurrection Church, or in the Devil King Tomb. Their partnership ultimately becomes romantic; they become engaged, plan a wedding in the Vihart Kingdom, and are later described as husband and wife 383 445.

• On their first meeting, Dekan opens his dorm door to find Cornelia, whose knock has visibly dented the panel; he nervously identifies her as the special qualifier who beat a Tier 4 examiner 9.
• In class, Cornelia sits beside Dekan, and he warns her that his body is fragile, to which she responds with a halting “I, I understand” 10.
• When Cornelia struggles to choose electives, Dekan proposes a deal—“Teach. Good at. Pay. Meal. Go.”—and they agree to study together and clear Baleful Intentdow Worlds as a team 11.
• During the Demon Academy exam, Dekan contacts his Master for answers, then quickly copies them onto Cornelia’s paper; she trusts his lead and follows his non-verbal signals to hand in her paper and wait outside 15.
• In the broadcasting room, Cornelia picks a lock for Dekan, proving her resourcefulness; later, they modify the equipment together to control the class-start music and neutralize the Dean of Students 27.
• When a Tier 5 challenger, the Faceless One, ambushes them, Cornelia takes a protective stance in front of Dekan, ready to fight, and he trusts her judgment 37.
• Dekan finds Cornelia feeding Sprite Cats on the back mountain; though the cats are afraid of her, she shows a gentle nature, and Dekan expresses a desire to help and make her happy 55.
• Dekan wants to bring Cornelia on his visit to Tristin Magic Academy, but Professor Arnold refuses; Dekan reluctantly agrees to go alone, complaining he will feel insecure without her protection 97.
• When Dekan is captured and imprisoned on a higher floor of the Baleful Intentdow World, Cornelia finds him, gathering information and showing determination and resourcefulness 258.
• At the end of the semester, Cornelia passes her exams with relief, knowing she will not be separated from Dekan, and she later helps him with recording sessions for the girl group 152.
• Cornelia becomes Dekan’s fiancée, with their wedding planned in the Vihart Kingdom; the two later return to the Norton Kingdom with their friends 383.
• When Dekan believes he has upset her, he is visibly at a loss and apologizes sincerely despite not understanding the exact reason for her tears 411.
• In later life, the pair work side by side in church and community duties as husband and wife 445.

Ice Princess (Claire)

Dekan’s relationship with the Ice Princess is professional, tinged with mutual intrigue and a subtle undercurrent of tension. He respects her authority as the Norton Kingdom’s only eighth-tier Special-Grade Card Maker, while she becomes increasingly supportive of his certification process despite rumors and political obstacles. Their interactions are characterized by formal politeness, but the Ice Princess reveals a personal, almost affectionate side in her private correspondence. Dekan, in turn, treats her as both a valuable ally and a potential source of conflict—careful not to provoke her, yet never fully trusting that the feeling is mutual. The arrival of Cornelia and Cat Teacher introduces a note of nervousness on both sides, hinting at deeper emotional undercurrents.

• Dekan learns he must undergo a one-on-one interview with the Ice Princess; Professor Arnold suspects he harbors “wicked intentions” toward her and warns him not to treat Tristin like the Demon Academy 97.
• Dekan visits Tristin Magic Academy for his special review, wearing formal attire and remaining calm and dignified; the Ice Princess is busy but allocates an hour for him 112.
• When Dekan brings Cornelia, Croix, and Cat Teacher to meet her, the Ice Princess shows nervousness—she has never met Cornelia or Cat Teacher before, and the two girls size each other up with mutual anxiety 150.
• After Dekan’s affiliation rumor spreads, the Ice Princess personally visits him to discuss the situation and reassure him of her support, demonstrating her loyalty 151.
• The Ice Princess sends Dekan a letter expressing gratitude and inviting him to meet again; the letter is affectionate enough that Cat Teacher teases it might be a love letter, causing Cornelia to overthink 149.
• Dekan recruits the Ice Princess into the girl group “Happy Church”; during dance practice she struggles with expressiveness, and Dekan guides her as manager and producer 152.

Cat Teacher

Cat Teacher serves as Dekan’s acerbic, feline companion who often criticizes his actions but remains deeply concerned for his welfare. Their banter is sharp and playful—she mocks him, he teases her back—but beneath the sarcasm lies genuine loyalty. Her presence also creates comedic friction with Cornelia, whose romantic anxieties she casually fuels. Cat Teacher’s inability to transform into a human is a running joke, and she frequently inserts herself into Dekan’s plans, whether he wants her there or not.

• When the Ice Princess’s letter arrives, Cat Teacher teasingly suggests it is a love letter, causing Cornelia to worry; Dekan and she then exchange banter about her love advice and her inability to turn human 149.
• Cat Teacher insists on accompanying Dekan to meet the Ice Princess; she leaps onto Cornelia’s lap and later watches the interaction with a critical eye 150.
• After Dekan’s affiliation rumor spreads, Cat Teacher expresses concern for his safety and the potential consequences of his actions 151.
• Cat Teacher acts as Dekan’s portable card inventory in Baleful Intentdow Worlds, carrying a full card-making toolkit, low-tier materials, and seized cards 86.
• Although Dekan regularly tries to force Cat Teacher out of his shadow, he eventually responds to her hiding with more indulgence than irritation 378.

Croix

Croix is Dekan’s healer and close friend, completing the “iron triangle” of warrior, mage, and healer that Dekan considers indispensable. Their camaraderie is relaxed and loyal, with Croix often providing both magical support and cheerful companionship. He is quick to follow Dekan’s lead in operations against the Resurrection Church and treats the Ice Princess as an old acquaintance, having fought alongside her before.

• Dekan wants to bring Croix and Cornelia to Tristin for the review, citing the need for a healer; Professor Arnold vetoes the idea 97.
• Croix and Cornelia arrive in Tristin City to assist Dekan in his campaign against the Resurrection Church; this marks their second official team-building activity, and Croix is happy to help with interrogations 118.
• Croix has already met the Ice Princess and exchanges banter with her naturally during the group’s visit to Tristin Magic Academy 150.
• Dekan makes Croix his Caster during the Bishop Duel against Fahim, using [Demon Curse Seal] to ensure Croix’s [Forced Dispel] is valid under the ritual’s rules 216.
• After the Tier 7 Baleful Intentdow World settlement, Croix advances from Tier 6 to Tier 7 and receives the [Illusion Stone Pendant] 291.

Mie

Mie is one of Dekan’s closest research partners and a trusted companion in his larger circle. Their relationship is founded on shared technical interests, particularly card crafting, poison research, and Magitech. Mie is often more perceptive than Dekan’s other companions regarding his actions and identity, but remains willing to cooperate with him when their goals align.

• Dekan and Mie spend time studying together in the card-making workshop after he acquires his Sprite Cat transformation 59.
• Mie accompanies Dekan during the Hero Festival period and helps assess the evolving battlefield situation around the Pope and other Bishops 316.
• Dekan, Mie, and Clay are known together as the “Three Bishops” while they research and maintain the [Spatial Leap Gate] 383.

Clay

Clay is a Resurrection Church Bishop whose identity, tools, and unusually poor relationships with fellow Bishops repeatedly become useful to Dekan. Although their association begins through conflict and impersonation, Clay later becomes part of Dekan’s close operational circle.

• Dekan uses Clay’s Bishop’s Token to impersonate him, contact other Bishops, and exploit Clay’s established reputation for gambling and borrowing money 208.

• Dekan develops a trauma-like insistence on keeping Clay within sight following later events 383.

Professor Arnold

As Dekan’s homeroom teacher, Professor Arnold oscillates between grudging respect and constant alarm. He recognizes Dekan’s intelligence and strength but is perpetually worried that Dekan will cause an irreversible incident. Their interactions are defined by Arnold’s attempts to rein Dekan in—stern warnings, careful questioning—and Dekan’s polite but evasive reassurances. The professor’s concern grows with each new exploit, yet he cannot help feeling relieved when Dekan returns safely.

• Arnold notices Dekan and Cornelia sitting together harmoniously in the back row and immediately suspects they are planning a “rebellion” 10.
• He warns Dekan sternly about behavior at Tristin: “You are going there for an exchange visit, not for an inspection” and “I certainly don’t want to be frozen into an ice sculpture” 97.
• Arnold grows increasingly worried about Dekan’s intentions toward the Ice Princess, believing Dekan has calculated his odds of winning against her 97.
• When Dekan returns from Tristin, Arnold’s conflicting emotions are written on his face; he sums up his feelings with “It’s good that you’re back,” though he thinks the hijacking was merely an appetizer for worse trouble 152.
• During the Hero Festival, Arnold watches Dekan’s high-stakes duel with intense concern but also pride, remembering the unusual student who once defeated him in Phantom Canyon 306.
• In retrospect, Dekan recognizes Arnold as a father-like mentor who helped smooth over many problems with the Kingdom Association during his reckless academy years 461.

Master

The relationship between Dekan and his Master is one of symbiotic antagonism: she often takes over his body without permission, he provokes her deliberately, and they bicker like old rivals. Yet there is a clear foundation of mutual dependence and respect. The Master provides Dekan with forbidden knowledge and card-making power, while Dekan gives her a physical anchor. Their arguments are frequent but punctuated by moments of genuine apology and understanding. As their journey progresses, the connection between their identities, Talomati, and the Devil King Tomb becomes increasingly important.

• Dekan loses consciousness and his cream puff when his Master hijacks his body; they then engage in a playful argument over dessert 149.
• The Master apologizes for using Dekan’s body without permission and promises not to do so again; the conversation is civil and shows growing respect 55.
• During the Demon Academy exam, Dekan contacts his Master for answers, demonstrating his resourcefulness and the unique bond that allows him to cheat with her help 15.
• Master gives Dekan essential intelligence on the Holy Rite Church Baleful Intentdow World and cautions him about the Undying Vampire Clan 154.
• Master reconstructs the Devil King Mark spell formation from memory, allowing Dekan to understand the Eighth Floor’s true challenge and work with her to break Carster’s illusion 278.
• Dekan becomes concerned when Master’s fragmented memories are stirred by the Demon Realm and Holy Kingdom connections within the Baleful Intentdow World 274.
• Dekan and Master discuss their apparent twin or sibling connection after encountering Talomati, though they humorously dispute which of them is older 335.
• Dekan remains determined to help Master recover a physical body and involve her in the ordinary daily life of the Happy Group once she can join it directly 385.

Talomati

Talomati is deeply connected to Dekan’s Master and becomes one of Dekan’s most important partners in high-level card crafting, spatial research, and the containment of extraordinary threats.

• Dekan collaborates with Talomati to create the Crimson Epic Equipment Card [Dekan Gospel] 187.
• Talomati’s appearance strongly resembles Dekan’s succubus form, prompting Dekan and Master to confront the implications of their familial connection 335.
• Dekan and Talomati cooperate closely during their renewed journey through the Holy Kingdom and Demon Realm, including the creation of a powerful curse-magic scroll 392.
• Talomati silently coordinates with Dekan while restraining Apotos and showing him the Chaos Gods imprisoned within the Devil King Tomb 425.

Synopsis

Dekan, a student at Havenlit Academy, quickly distinguishes himself as an unorthodox and ruthlessly strategic card maker and duelist. From his earliest days, he demonstrates a penchant for psychological warfare and unconventional tactics, such as using pain-inducing cards to overwhelm examiners and securing top rankings. His ambitions extend beyond the academy: he seeks to master card crafting, clear Baleful Intentdow Worlds for resources and power, and repay his debts—especially those to his mysterious Master. Along the way, Dekan forms key alliances with the noble Theresia, the warrior Cornelia, and the enigmatic Cat Teacher, while also drawing the attention of powerful forces. His increasingly sinister card-making style—producing forbidden, devilish cards that amplify desire or enslave beings—leads the Card Maker Association to fast-track him for Special-Class certification. However, it also makes him a target: the Resurrection Church, a fanatical cult, attempts to publicly claim him as one of their own and plots his capture. Dekan responds by systematically dismantling the Church’s assets, exploiting its members, and preparing for a “massive reckoning” against his enemies. His journey culminates in mastering the powers of a Devil King within a Baleful Intentdow World, forging alliances with mythical strategists, and resolving to conquer a Tier 7 Baleful Intentdow World while bracing for the Church’s inevitable retaliation.

After clearing the Tier 7 Baleful Intentdow World and advancing to Tier 5, Dekan becomes publicly known as the Bishop of Pain and enters conflicts extending beyond the Norton Kingdom. He participates in the Hero Festival, confronts enemies vastly stronger than himself through hidden card systems and manipulation, and becomes increasingly entangled with the Devil King Tomb, the Holy Kingdom, and Master’s lost history. His influence later expands from card crafting and politics to spatial research, ninth-rank Baleful Intentdow World conquest, control over a Void Gate, and the imprisonment of Chaos Gods. Despite this rise in power, he retains his ties to Havenlit Academy, the Happy Group, Cornelia, and the community church where he eventually teaches medicine and antidote-making 291 306 383 406 425 445.
