William

William Von Ainsworth is a reincarnated Half-Elf whose refusal to abandon the people he loves carries him from shepherding goats in Lont to founding an empire, uniting Hestia, and defeating the God of Destruction Surtr.

Biography

Lont and Hestia Academy

William's second life begins with the values that ended his first. Sickly and raised in an orphanage on Earth, he gives his heart to save Belle, leaves her a letter urging her to live without regrets, and enters the Temple of the Ten Thousand Gods worrying about her survival rather than his own death. His concern for hungry children also recalls how he shared his limited meals at the orphanage. Offered another life, he chooses Gavin after the God of All Trades honestly explains both the benefits and limitations of his blessing; Issei, Lily, and David add their own gifts before an accident sends William to Hestia instead of his intended destination. That beginning establishes the two impulses that continue to govern him: an irreverent appetite for life and a willingness to spend himself for other people. (Chapters 1–6)

Born the weak son of Arwen and Maxwell, William is separated from his mother for his protection and brought to Lont. Ella, initially an Angorian goat, nurses and raises him as her child, while James and the wider Ainsworth household become the family he lacked on Earth. The System left dormant by his damaged soul begins responding as he grows; through the Ring of Conquest and his work as a shepherd he opens job classes, raises his herd, and learns to treat beasts as companions rather than disposable summons. Discovering that the Ring belonged to Maxwell forces him to confront the hidden cost of his birth: his father fought the Demon Lord, saved the damaged World Tree by fusing with it, and left William both a legacy of power and enemies among the Elves. (Chapters 7–15, 43–51, and 89–90)

Celine gives William rigorous martial and dark-magic training, but she also places a slave collar on him and subjects him to a trial that leaves genuine resentment between them. William does not pretend that the betrayal never happened; when they discuss it, he accepts Celine's refusal to apologize and promises that he will become strong enough to settle their debt himself. Their relationship consequently grows through confrontation rather than easy forgiveness: he keeps her secrets when questioned, continues to train under her, and gradually understands that her own collar and childhood were bound to the same prophecy that threatens him. His daily discipline—martial practice, work, cooking, and caring for the goats—turns the frail reincarnate into a capable fighter without erasing his grievance or his affection for his master. (Chapters 100–107, 115–116, 130, and 182)

At the Hellan Royal Academy, William is placed among the Martial Classes and refuses to be ashamed of calling himself a shepherd. He wins authority by confronting stronger opponents, then uses that authority to train students whom the academy's other divisions dismiss. When war becomes likely, he offers them a real choice: leave without retaliation, or sign a blood contract and stand beside him through danger. Thirty-six remain, and William founds the Angorian War Sovereign around their trust, promising in return to make them strong. The Dungeon Outbreak tests that promise immediately; he changes classes tactically, calls beasts and allies to the field, and takes responsibility for directing a defense larger than anything he faced in Lont. He ends this phase not merely as a gifted student, but as a commander whose followers have chosen him knowingly. (Chapters 129–145, 166–188, and 212)

War, Babylon, and the price of command

The Southern Continental War forces William to turn his youthful chivalry into political judgment. In the Kyrintor Mountains, he intervenes when Brianna is to be used in an unwanted marriage, partly because his own arranged engagement taught him what that loss of choice feels like. Challenging Prince Aziel also serves a military purpose: William recognizes that victory can fracture the alliance threatening Hellan and give his delegation a chance to leave alive. He accepts that he has no safe alternative, defeats Aziel, and claims the Onyx Medallion; later, he uses the Ant Queen's fear of Kasogonaga to secure permission to command its summoned soldiers. His methods are frequently shameless, but they are directed toward protecting his people and denying his enemies uncomplicated control. (Chapters 247–250 and 354)

William pays personally for fighting above his rank. After grave damage to his soul leaves him half-dead, his first concern in the Temple is whether Wendy and the others survived. The gods warn that forcing himself awake could collapse his soul for a thousand years, yet he undertakes divinity training because remaining helpless while war continues is unacceptable to him. David advances his Shepherd class into Quick Shot Shepherd, and William wins the right to invoke Heroic Avatars; the ordeal changes his battlefield role from a flexible class-user into the center of a growing combined-arms force. He subsequently plans his King's Legion around complementary riders, beasts, familiars, and weapons rather than assuming that his personal strength can win a war alone. (Chapters 293–319 and 365–367)

That philosophy carries him through the collapse of the Southern Continent's old order. When the Continental Spell turns adults into crystal and leaves children to survive the Elven advance, William bargains for troops, protects refugees, and works with imperfect allies whose interests overlap his own. He uses the Thousand Beast Domain as shelter as well as an arsenal and accepts responsibility for those placed inside it. His bond with Ashe, who shares his soul through Familia synchronization, also changes his understanding of power: the System can integrate one of his classes into a bonded partner, allowing both to grow, but that benefit depends on their relationship rather than simple possession. (Chapters 342–375, 407, and 431–460)

The Tower of Babylon raises the cost of command again. On its fifty-first floor, William fights through a trial long regarded as unconquerable, marries Chiffon, and assumes control of multiple Tower floors. The victory gives him resources and status comparable to an emperor, but it also makes the displaced ruling families his enemies and binds him to govern the domains he took. He reorganizes their trials instead of treating them as trophies, while Chiffon's concern exposes the continuing price of his vampiric condition: he must drink blood, yet refuses hers because he fears losing control and harming her. By the end of this phase, he has gained world-shaping territory, a wife, and a legend, but each gain carries a new person or population for whom he feels responsible. (Chapters 565–592 and 630–650)

The Deadlands and the Central Continent

William's new position attracts teachers, rivals, and prophecies. Celeste enters the supposedly closed Floor of Asgard to teach him as a Familiamancer, while Chiffon insists on identifying the Virtue she represents before allowing her close. William mediates rather than dismissing his wife's fear, and his training produces Elliot and Conan as complementary offensive and defensive familiars. At the same time, he learns that the Elves consider him a possible Prince of Darkness. He rejects the title and refuses the prophecy's presumed hatred—his mother is the Elven Saintess, and he does not want the race destroyed—but he does not ignore the warning or the earlier occasions when dark power answered him. (Chapters 651–664 and 679)

In the Central Continent, William alternates institutional duties with direct missions: he attends Hestia Academy, tests his growing party against dungeons, and earns cooperation from groups that initially know him only by reputation. He delegates protection instead of insisting on occupying every role himself, assigning Conan to guard Aila when his own assessment team is full. His wider preparations are driven by warnings that Malacai's release and the coming war place the whole world at stake. Even before he knows the final form of that threat, William begins knitting together people whose classes, divinities, and loyalties can cover one another's weaknesses. (Chapters 714–751 and 764–782)

The Deadlands confront him with the limit of that preparation. After Morax's struggle traps William among displaced souls and future echoes, he comes to love Raizel as his daughter; when the God of Death cuts her down protecting him, grief awakens a darkness powerful enough to crack the sky. William declares that he will surrender nothing to Death, but the Primordial Goddess stops the awakening before it completes and compels the God of Death to restore Raizel because her proper time has not come. The rescue is not William's victory, and the source makes that distinction clear: his rage reveals what he may become, while divine intervention prevents that possibility from being tested. (Chapters 821–866)

Returned to Earth through the Deadlands' exit, William chooses not to repeat the regret of his first life. He openly identifies himself as Belle's fiance, tells her parents that he cannot promise constant presence across worlds but can promise wholehearted love whenever they are together, and asks to marry her. When a divine assault threatens the city, he cannot summon his full legion under Earth's laws and is physically outmatched by a black golem. He nevertheless keeps intercepting attacks aimed at civilians, heals what injuries he can, and returns to battle after acknowledging that heroes can bleed. His time with Belle ends with a promise to give her the happiest ending he can, even though neither knows how little control he has over the price his future darkness will demand. (Chapters 886–917)

The Heir of Darkness and the Underworld

Back in Hestia, William enters the Demon Continent to disrupt the Gremory Clan's invasion and move vulnerable clans into the Thousand Beast Domain. His strategy is not purely military: he coerces or persuades clan patriarchs, creates homes and access to Atlantis for their people, and gives those unwilling to fight the option of shelter on Asgard. The call from the northern ruins repeatedly destabilizes his dark magic, but he resists it while continuing the evacuations. That effort brings him into the confrontation with Felix and Ahriman for which neither his preparations nor his legion are sufficient. (Chapters 989–1030 and 1100–1101)

The northern battle destroys the emotional foundation of William's resistance. His wives fall, Elliot and Conan sacrifice themselves, Ella spends her vessel to shield his retreat, and trusted companions die while he is unable to intervene. In his shattered Sea of Consciousness, the Primordial Goddess offers the strength to save those still alive in return for his heart and memories of Belle; when his damaged soul cannot answer, she makes the choice for him and fills it with darkness. Amalthea's silver bell preserves part of his soul and briefly shelters his memories, but using the new power consumes them. William awakens changed—black-haired, emotionally blunted, dependent on blood, life essence, and magic while his corruption stabilizes—and directs the grief he can no longer fully express into vengeance against Felix and Ahriman. (Chapters 1060–1100)

Rather than charge back unprepared, William accepts how badly he lost and builds an army capable of contesting Pseudo-Gods. He restores the Deadlands inside his Domain, advances to Demigod rank, conquers high-level dungeons, and uses the Dungeon Conqueror's access to cores to turn guardians into subordinate powers. Against Atlantis, he combines the Nymphs' aim, trajectory, and distance with the attacks of his other Pseudo-Gods, while Heroic Avatar allows him to face Leviathan at peak Pseudo-God strength for a limited time. This accumulation is instrumental rather than triumphant: William explicitly regards himself as the weakest great power and seeks enough strength to avenge the dead and prevent a second massacre. (Chapters 1134, 1188–1202)

When the rematch comes, William's forces finally overwhelm Felix's army while Gavin confronts Ahriman's avatar. William uses synchronized Familia divinities and the power of his conquered guardians to defeat Felix, then declares himself Demon Lord and ends the Demon Continent's cycle of clan conquest. Victory cannot return the souls taken north, so he enters the Underworld alive, earns passage through its layers, finds his wives and the pregnant Celine, and seeks the God of Death rather than accepting separation as final. His journey also creates a bond with Erinys, whose help brings him to the last layer despite her fear that his reunion will end their shared story. (Chapters 1246–1267 and 1281–1318)

The Grand Alliance and the War of Destruction

William reunites with Ashe, Sidonie, Morgana, Chiffon, and Celine in the Underworld, but bringing them permanently back to Hestia is not an immediate or cost-free act. Once he returns to the surface, he redirects his empire from revenge toward survival: the Army of Destruction will arrive in two years, and no individual kingdom can resist thousands of high-ranked giants and multiple gods. He visits rulers himself, admits that he does not know whether victory is possible, and asks mortal armies to handle threats within their reach while experts pool technology against the greater ones. When argument alone is insufficient, he stages a controlled giant attack to make the danger credible, a manipulative choice he accepts as preferable to letting disbelief leave the world unprepared. (Chapters 1301–1318 and 1364–1391)

The Grand Alliance depends as much on William surrendering control as exercising it. Nisha administers the Ainsworth Empire and manages coercive negotiations William is unwilling to conduct personally; kings retain their commands; Dwarves and other specialists develop weapons; Demigods and dungeon guardians receive roles suited to their scale. William's task becomes holding these incompatible factions to one objective. His wedding shortly before the invasion gives that objective a human form: surrounded by family, former rivals, rulers, gods, and the women whose lives are bound to his, he accepts a moment of happiness precisely because none of them can assume they will survive to enjoy it later. (Chapters 1376–1422)

At the final battle, William tells the assembled forces that they are fighting not for glory but for the people and future behind them. He confronts Surtr while the Alliance handles the wider Army of Destruction, repeatedly placing himself between world-ending attacks and Hestia even when the difference in raw strength remains clear. His indestructible wooden staff lets him survive exchanges that ordinary weapons could not, but defense alone cannot win; the accumulated powers of the Sins, Virtues, familiars, wives, and companions become the decisive answer. Their union changes the staff into the Sword of the Strange Hangings and gives William strength beyond Surtr's. (Chapters 1436–1461)

William takes the fight into the Void so their full power will not destroy the world they are saving. There he rejects Surtr's claim that Hestia must die for the cosmic cycle, declaring that his role is simply to stop that destruction, and their final attacks cut Interitus apart and kill the Fire Giant. William then allows Yaldabaoth and the surviving Army of Destruction to withdraw because destruction still has a place in the multiverse; he separates that larger balance from his personal debt to Ahriman, whose soul he captures and hands to Nyx. The choice marks the end of his development from a boy who tried to solve every threat himself into a ruler able to distinguish protection, vengeance, and the limits of his responsibility. (Chapter 1462)

In the after story, William remains in the Ainsworth Empire with his wives and children rather than seeking another conquest. He is still identified as a powerful Pseudo-God, but domestic life, marriages, and family occupy him more than rank. His final act with David's wooden staff is to release it: he thanks the weapon that crossed both lives with him, blesses it to aid a future bearer who protects the weak, and accepts that his own journey with it is finished. He ends not by possessing every source of power he acquired, but by sending his oldest weapon onward and choosing to be happy with the life he fought to preserve. (Chapters 1463–1473)

Appearance and personality

William is a handsome Half-Elf with pointed ears. During his academy years he has flame-bright red hair, clear light-green eyes, and a lean, toned body developed through labor and martial training; his hands remain callused from shepherding, chopping wood, and daily practice. When the Primordial Goddess fills his damaged soul with darkness, his hair turns black, his eyes become golden, and an obsidian gem manifests at his chest. After the final conflict, he is again described as red-haired, while divine transformations can add traits such as wings or regalia that are not his ordinary appearance. (Chapters 130, 140, 170, 1090, and 1462)

He is theatrical, flirtatious, and fond of teasing, but the comedy sits beside an unusually direct awareness of resentment and mortality. William openly admits that he holds grudges and does not offer forgiveness merely to appear virtuous; he also repeatedly risks himself for civilians, family, companions, and subordinates. His leadership is pragmatic enough to bargain, blackmail, delegate, and deceive, yet he generally gives dependents shelter and followers a choice before demanding their service. Later darkness dulls the feelings visible on his face without erasing them—his involuntary tears before his frozen wives show that grief survives beneath the altered temperament. (Chapters 1, 182, 188, 354, 917, 1100, and 1387)

Skills, classes, and divinities

William's power is a layered combination of System-mediated job classes, divine gifts, bonded companions, conquered dungeons, and equipment. The layers are not interchangeable: the System lets him change and develop classes, Heroic Avatar temporarily borrows a recognized hero's complete arsenal, Familia synchronization depends on a relationship, and several of his most spectacular attacks require sentient weapons or other people's divinities.

Strongest System and job-class switching

Gavin's blessing gives William twenty percent additional job experience, an extra skill point per class level, and the theoretical ability to merge ten unlocked professions. Gavin also places a CPU core in his soul; the resulting System later speaks as Optimus, tracks status and maps, performs calculations, stores class data, and can switch William's active subclass in response to danger. The System does not remove external requirements: individual advanced classes still require prerequisites, and its estimates can be uncertain when facing powers outside its data. Its greatest tactical advantage is breadth—William can move between martial, magical, healing, crafting, mounted, and support roles rather than remaining bound to one profession. (Chapters 5–7, 20, 170, 182, and 407)

Shepherd, Quick Shot Shepherd, and the King's Legion

William's foundational Shepherd class develops through his care for Ella and the herd, granting beast communication, growth paths, and the ability to organize magical beasts. Its advanced form, Quick Shot Shepherd, adds enhanced stamina and attributes, resistance to debuffs and nature magic, terrain mobility, ambidexterity, a chosen favored-enemy bonus, and Mythic Wild Empathy. Quick Shot and Fast Reload apply not only to projectile weapons but to spells, while the favored-enemy effect requires a designated target type. The class therefore turns his apparently humble profession into a command-and-fire-support specialization rather than a simple melee upgrade. (Chapters 15, 51, and 314–317)

The Quick Shot War Arts channel aura through a weapon as escalating ranged attacks. Railgun fires a concentrated shot with enough recoil to drive William backward and destroy a Centennial-ranked opponent's arm; later forms scale through Grand Bazooka to The End, whose collision with Leviathan's World Ender makes the Atlantis floor collapse. The growth in output does not erase the danger to William or his surroundings: recoil, enemy durability, and catastrophic collateral effects remain practical limits, which is why his greatest applications occur in sealed domains or away from allies. (Chapters 319 and 1201)

Heroic Avatar and borrowed heroes

Heroic Avatar is acquired with Quick Shot Shepherd after William earns his advanced class. In its stated base form it lets him wield all abilities, weapons, and battle regalia of one Immortal Hero for fifteen minutes and can be used once every twenty-four hours; duration and performance vary with the chosen hero, and the hero must first recognize him. William's best-known synchronization is with Sun Wukong, through whom he gains the Monkey King's body, Fiery Golden Eyes, transformations, and mastery of Ruyi Jingu Bang. Even this state can be injured by superior divine constructs, and its temporary nature forces him to plan around the window rather than treating it as permanent rank. (Chapters 317, 672, 866, 917, and 1201)

Dungeon Conqueror and the Thousand Beast Domain

The Ring of Conquest connects William to dungeons and the legacy Maxwell left behind. Early on it enables leveling and storage; as the inheritance develops, William registers and conquers dungeons, brings beasts and people into the Thousand Beast Domain, and commands a King's Legion drawn from its residents. Dungeon conquest is not automatic: cores must be found and subdued, and a guardian can exploit its native terrain. As Dungeon Conqueror, William discovers that locating and taking a core can bypass a seemingly unbeatable final-floor formation, but this tactic requires repeated observation and successful access to the core room. (Chapters 43–51, 89–90, 398–407, and 1188–1202)

The Domain becomes more than a summoning space. William uses it to shelter refugees and entire Demon Clans, train forces in Atlantis, preserve the Deadlands, and deploy or withdraw combatants through portals. It also imposes logistical and ethical responsibilities: its residents need homes, governance, food, and protection, and Hestia's laws can prevent him from summoning the Legion in another world. Its latest military form includes beasts, knights, familiars, Demigods, and conquered Pseudo-Gods, but their power remains their own even when they accept William's command. (Chapters 365–367, 407, 917, 1001, 1100–1101, and 1134)

Familia synchronization and shared divinities

The King's Chess Piece establishes a Familia framework through which William can synchronize with bonded partners. Synchronization grants him access to a partner's abilities and attribute enhancements, while subclass integration lets him assign one of his own classes to the partner so both can benefit from experience. The bond's strength rises or falls with the relationship, and some effects require a high synchronization rate; it is neither blanket ownership nor proof that William permanently possesses a partner's divinity. (Chapters 4, 407, and 749)

At high synchronization, William can combine Familia powers tactically—for example, altering speed and strengthening attack and defense through the divinities of his allies during the battle with Felix. In the last confrontation with Surtr, the Eight Deadly Sins and Eight Heavenly Virtues consciously channel their powers into the Sword of the Strange Hangings. That final union depends on their presence and consent; it is a culmination of William's bonds, not an innate catalog of sixteen divinities that he can freely reproduce alone. (Chapters 1246–1247 and 1461–1462)

Darkness, Rulebreaker, and divine state

William's Prince of Darkness power is forced into his damaged soul by the Primordial Goddess after the northern catastrophe. It grants immense dark power and Rulebreaker, which can coat attacks to negate or break supernatural effects, but its awakening initially requires blood, life essence, life magic, and the power of divinity-bearing people. Its gravest cost is personal: using the darkness consumes the Earth memories guarded by Amalthea's bell, while complete corruption threatens the portion of William's identity that remains. He therefore spends a long period gathering power and stabilizing himself rather than having immediate mastery. (Chapters 1090–1101 and 1134)

Rulebreaker lets William's attacks pierce effects that would ordinarily govern a battlefield, as when it breaks water tornadoes in Atlantis. It is not shown as universally irresistible: Shannon's divinity is considered dangerous enough that even Chloee's Rulebreaker may not stop it, and stronger opponents can still injure or overpower William. After the wars against Felix and Ahriman, William's appearance and emotional range recover, and in the battle with Surtr the narrator describes his ascent from mortal to God; the later after story, however, calls him a powerful Pseudo-God. The safest latest-state description is therefore that he survives with divine-scale power, while the exact permanence of his godhood is not clarified. (Chapters 1134, 1200, 1462, and 1470)

Magic, crafting, and martial versatility

William accumulates many secondary classes, including elemental mage, life-magic, alchemy, blacksmithing, monk, cavalier, and ranged-combat paths. Demonstrated applications include Icycle Realm as a high-level Ice Wizard spell, life magic for healing, lightning movement and attacks, alchemical weapons for his army, and class switching to answer particular opponents. These competencies make him adaptable, but they are not equally mastered at every point, and several large effects come from equipped weapons or Heroic Avatar rather than from the classes alone. (Chapters 20, 170, 223, 369, 430, 917, and 1472)

Power progression

Relationships

• Belle: William's first love on Earth and the person for whom he gives his heart. Their separation shapes his fear of regret; even when darkness consumes his memories of her, the surviving bond drives their eventual reunion and marriage. (Chapters 1, 893–901, 1090, and 1422)
• Ella: His adoptive mother, first herd companion, and moral refuge. Ella raises him from infancy, later reveals her divine identity as Amalthea, sacrifices her vessel, and leaves her bell with him to preserve part of his soul. (Chapters 8–15, 112–116, 1077, and 1100)
• Celine: William's master, former captor, lover, wife, and mother of his son Ciel. Their bond contains real resentment alongside loyalty; neither erases the harm of the collar, but both repeatedly protect the other from the prophecies surrounding them. (Chapters 100–116, 182, 1030, 1090, and 1422)
• Chiffon: His wife from the Tower of Babylon, whose Gluttony and difficult family history help shape his wars with the Demon Continent. William protects her without treating her as helpless, and she remains one of the clearest anchors for his tenderness. (Chapters 588–650, 1000–1004, and 1391)
• Sidonie: A political rival and ally who becomes William's wife and a central Familia bond. Their relationship links personal intimacy to strategy, particularly through the Sin of Lust, but Sidonie retains her own army and political will. (Chapters 307–308, 418–419, 749, and 1301)
• Ashe: William's lover and wife, first registered Familia member, and a soul-linked partner whose synchronization helps establish the System's shared-class mechanics. (Chapters 300, 365–367, 407, and 1301)
• Wendy: A fellow academy student who openly loves William, fights under his banner, and becomes one of his wives. Her trust accompanies his development from head prefect to world leader. (Chapters 161–170, 300, 407, and 1422)
• Est: William's academy companion, ally, lover, and eventual wife Estelle. Their friendship survives concealed identity, war, and long separation, and Est remains tied to the Angorian War Sovereign William first founded at school. (Chapters 61–77, 140–188, and 1422)
• James: His grandfather and the Ainsworth patriarch who raises, trains, protects, and repeatedly maneuvers institutions to give William room to grow. William inherits both James's loyalty to family and his taste for audacious bargaining. (Chapters 8–10, 89–90, 181–188, and 1391)
• Optimus: The System intelligence that advises William, calculates odds, manages classes and maps, and warns him when its conclusions are only estimates. Their partnership is constant, but William still makes the moral and strategic choices. (Chapters 182, 407, 917, 1188, and 1421)
• Elliot: One of William's principal familiars and counselors. Elliot's sacrifice contributes to William's fall into darkness, while his return for the final clash embodies the friendship William believed he had lost. (Chapters 664, 1090, and 1462)

Items

• David's Wooden Staff: David's reincarnation gift and William's longest-serving weapon. Its true form is the Sword of the Strange Hangings; after defeating Surtr, William releases it to seek a worthy future bearer. (Chapters 6, 1460–1462, and 1473)
• Soleil: A sentient fire spear that attacks independently, enables teleportation, and fights alongside Stormcaller; its effects are equipment-derived rather than William's innate magic. (Chapters 250, 631, 672, and 1449)
• Lily's Lollipops: Lily's divine gift develops into varied consumable or wielded effects, including magical attacks and protection against fear for William's forces. (Chapters 6 and 366–367)
• Stormcaller: William's sentient lightning spear, capable of autonomous attacks and electrical discharge. (Chapters 112–113, 631, 917, and 1449)
• Ruyi Jingu Bang: Sun Wukong's size-changing golden staff, available through Heroic Avatar and used against divine-scale opponents. (Chapters 866, 917, 1201, and 1246)
• Ring of Conquest: The ring Maxwell took from the Demon Lord and left to William; it anchors William's dungeon inheritance, storage, equipment access, and conquest-related growth. (Chapters 43–50 and 89–90)
• Mithril Slave Collar: The collar Celine places on William, binding their early master-disciple relationship to coercion and to the larger Prince of Darkness prophecy. William never treats that history as harmless. (Chapters 108–116 and 182)
• King's Chess Piece: Issei's piece of divinity, placed in William's soul before reincarnation and later used by the System to support Familia and subclass integration. (Chapters 4 and 407)
• Amalthea's Silver Bell: Ella's safeguard within William's heart. It protects part of his soul and temporarily stores his memories of Belle against the Primordial Goddess's corruption, though repeated use of darkness can still consume them. (Chapters 1077, 1090, and 1100)
• Onyx Medallion: A relic taken after William defeats Prince Aziel. With the Ant Queen's permission it summons a limited ant force, including one Millennial, twelve Centennial, and one thousand lower-ranked soldiers. (Chapters 248–250 and 354)
