Eugene Lionheart

Eugene Lionheart is the reincarnation of the mercenary hero Hamel Dynas and, before him, the ancient War God Agaroth. Born into the bloodline of his former companion Vermouth, Eugene turns the talent and relationships of his new life toward the promise Hamel's party failed to fulfill: defeating the remaining Demon Kings and rescuing Vermouth rather than accepting another sacrificial victory. (Chapters 1–2, 541, and 612–625)

Biography

Hamel's Death and Lionheart Rebirth

Hamel begins his final assault on the Demon King of Incarceration's castle already injured beyond recovery, but refuses his companions' order to withdraw because survival as a permanent burden feels worse to him than dying in their cause. When he believes Vermouth is in danger, he spends his last strength pushing him aside and takes the fatal blow himself. The choice grows from both loyalty and an inferiority complex: Hamel knows Vermouth may not have needed saving, yet he still wants his broken body to accomplish something honorable for the companions he cannot bear to leave. (Chapter 1)

Three hundred years later, Hamel awakens as Eugene, the son of Gerhard Lionheart from a collateral branch of Vermouth's clan. The reincarnation gives him a gifted, unscarred body and a childhood in which he can rebuild every foundation that had limited Hamel, but it also surrounds him with distorted stories about the "Stupid Hamel" and the achievements of friends whose later choices he does not understand. Eugene trains relentlessly from childhood, partly to exploit this second chance and partly to prove that he can finally escape Vermouth's shadow without pretending his first life never existed. (Chapters 2–3)

At the Bloodline Continuation Ceremony, Eugene's experience lets him read danger, coordinate the other children, and defeat opponents who have already begun mana training. His victories over Cyan and the main-family candidates expose the difference between his mature combat judgment and their inherited advantages, yet they also begin relationships that are more important than succession. Eugene needles Cyan rather than consoling him, but his unbroken training becomes the example that pulls Cyan out of despair; Ciel's games and rivalry likewise develop into a genuine sibling bond. By winning the ceremony and choosing Wynnyd from the treasure vault, Eugene earns access to Vermouth's legacy instead of receiving it merely because of his surname. (Chapters 8–19 and 26–27)

Gilead offers to adopt Eugene into the main family, but Eugene makes Gerhard's wishes the deciding condition and is willing to return to Gidol if adoption would hurt his father. Once Gerhard agrees, Eugene accepts the opportunities of the main line while continuing to recognize Gerhard alone as his father. He initiates mana through the White Flame Formula, turns its superior foundation into rapid growth, and reaches the Third Star at seventeen. His subsequent decision to leave the estate for Aroth is not a rejection of the Lionhearts: he judges that remaining comfortable would slow his growth, while learning magic will broaden the power he needs for the unfinished war. (Chapters 20–27)

The Unfinished War

In Aroth, Eugene studies magic under Lovellian, meets Mer within Sienna's preserved Witch Craft, and follows the traces Sienna left for Hamel rather than treating her legacy as an abstract scholarly prize. His reunion with Sienna's projection confirms both the tenderness hidden beneath their old quarrels and the failure that shaped the surviving party: Sienna had sealed Hamel's recovered soul because she and the others refused to let him pass on before they could fulfill their promise. Eugene learns that Vermouth's pact saved the party and returned Hamel's body and soul, which complicates his anger without answering why Vermouth arranged his reincarnation. (Chapters 26–53 and 104–113)

The search for answers also gives Eugene relationships that belong specifically to his present life. He recognizes Anise within Kristina and gradually stops treating Kristina as only a vessel for an old companion; their shared battles make both Saints partners who can challenge his recklessness and sustain powers that would otherwise destroy him. Reuniting with Molon reveals the cost of the centuries Eugene did not live: Molon has spent generations holding back the Nur beyond Lehainjar and tries to drive Eugene away from that burden. Eugene refuses to abandon him, confronts him as an equal, and restores the companionship that despair and isolation had worn down. (Chapters 182–220 and 228–248)

When Raizakia's curse and dimensional prison threaten Sienna, Eugene makes rescuing her a personal obligation rather than waiting for a safer campaign. He enters the dragon's territory, openly identifies himself as Hamel, and commits every available technique even when the combination of Ignition, Prominence, and Agaroth's Ring brings him near death. Sienna's intervention prevents his defeat, but Eugene lands the killing blow that severs Raizakia's Dragon Heart and then turns immediately to whether she survived. The victory reunites Sienna with both Eugene and Mer and changes the old party from separated survivors into companions who can act together again. (Chapters 287–305)

The battle against Iris, the new Demon King of Fury, forces Eugene's accumulated identities into the open. He fights beside Sienna, Kristina, and Anise, loses control of the Moonlight Sword, and awakens a Divine Sword from the divinity once carried by Agaroth. After the victory, Ciel answers his fear of becoming alien to his family by insisting that Hamel and Agaroth matter less to her than the fact that he is Eugene Lionheart. Later, the false Hamel embodied by the Specter makes that distinction violent: Eugene defeats a being with Hamel's memories because memory and copied technique do not outweigh the life, choices, and growth through which Eugene has surpassed his former self. (Chapters 367–390 and 478–496)

Divinity and the End of the Demon Kings

The revelations surrounding Agaroth initially tempt Eugene to divide his ancient bonds from his present self. His memories show a God of War who failed against Destruction, while the Sage recognizes Agaroth in him without claiming that Eugene is unchanged. During his promised duel with Gavid, Eugene reaches a different conclusion: rejecting Agaroth's bonds would also reject the sacrifices and hopes that made Eugene's existence possible. He combines Agaroth, Hamel, and Eugene without surrendering his present identity, transforms Prominence into a sanctuary, and forges his inherited powers into Levantein. Defeating Gavid proves that he has surpassed the god Gavid once killed and can pursue victory rather than repeat Agaroth's defeat. (Chapters 518–539)

Noir's challenge is harder because it cannot be reduced to strength. Her bond with Eugene carries both her love for Hamel and the unresolved relationship between their earlier incarnations, while her nightmare offers him peaceful lives if he abandons the purpose that defines him. Eugene refuses both the dream and the easier choice of sparing her at the cost of his own conviction. He kills Noir after a battle in which each understands the other's intention, and the victory leaves him grieving rather than triumphant. That pain demonstrates his development: he accepts Agaroth's emotions and Noir's importance without allowing either to dictate a future contrary to Eugene's chosen responsibilities. (Chapters 539 and 549–568)

As the final war approaches, Eugene accepts faith he once found embarrassing because believers are entrusting him with their hope of survival. He absorbs the accumulated power of the Light, organizes the Divine Army, and ascends Babel with Sienna, Kristina, and Anise while his allies hold the battlefield below. Against the Demon King of Incarceration, Eugene rejects the fatalistic claim that repeated destruction makes resistance meaningless. He fights through the Demon King's prison of darkness, combines his miracles with Sienna, Noir's Demoneye, the Saints, and Molon, and helps achieve the victory that Hamel's party could not reach three hundred years earlier. (Chapters 569–594)

Destruction's arrival immediately after that victory threatens to recreate Agaroth's worst failure, but Eugene refuses to command the Divine Army into a futile death or to sacrifice a companion for a temporary reprieve. Fighting with Sienna, Molon, Vermouth, the Saints, and even the defeated Incarceration, he turns the world's desire to survive into the divinity of victory and destroys Destruction's heart. He then insists on saving Vermouth rather than accepting that his body must vanish with Destruction. In the peace that follows, Eugene builds Dynas Academy so students can learn widely and choose their own futures, and finally proposes marriage to Sienna, Anise, and Kristina—commitments beyond the endless wars that once defined him. (Chapters 595–625)

Appearance and personality

Eugene grows into a broad-shouldered, physically powerful young man with shaggy ash-gray hair and golden eyes. His second body is naturally handsome and free of the scars that covered Hamel's face, a difference Sienna notices immediately when she recognizes him. He maintains that body through daily training and treats its talent as an opportunity to correct the physical limits of his first life, not as a reason to become complacent. (Chapters 26, 106, 171, and 567)

His manner remains blunt, profane, competitive, and quick to challenge pretension. Eugene enjoys praise more than he admits, hates being dismissed, and often hides embarrassment or affection behind insults. Those traits coexist with disciplined judgment: he studies opponents, changes weapons and tactics without attachment, and trains even when his progress already surpasses his peers. His confidence is therefore not passive arrogance; it is tied to the belief that despair only widens the distance from someone who continues working. (Chapters 2, 26–27, 172, and 389)

Eugene's fiercest choices are usually protective. He accepted death for his companions as Hamel, puts Gerhard's well-being ahead of adoption, takes responsibility for people harmed under his protection, and repeatedly risks himself to recover Sienna, Molon, and Vermouth. His weakness is that this responsibility can become self-destructive: Ignition, the Moonlight Sword, and Levantein all tempt him to accept bodily ruin as the price of a decisive victory. Over time, his companions make him recognize that victory means returning with them, not merely dying after accomplishing the objective. (Chapters 1, 22, 163, 299, 372–374, and 587–613)

Abilities and powers

Eugene combines Hamel's lifetime of combat experience with an exceptionally mana-attuned Lionheart body, formal magic education, spirit contracts, and the divinity carried through his reincarnations. His greatest strength is not any single inheritance but his ability to analyze systems, rebuild them around his own needs, and make weapons, magic, and divine power operate as one fighting style.

White Flame and Ring Flame Formulas

Eugene begins mana training at thirteen after entering the Lionheart main family. The White Flame Formula divides the mana around his heart into Stars and circulates their output through his body; compared with Hamel's old scripture, it absorbs mana faster, uses small reserves efficiently, and converts that mana into physical strength at lower cost. His past experience with circulation and his new body's natural affinity let him reach three Stars by seventeen, while later breakthroughs take him through the Dark Room and beyond the ordinary Lionheart progression. (Chapters 23–27, 39, and 208–216)

After studying the Eternal Hole within Witch Craft, Eugene grafts its principle of chained circulation onto the White Flame Formula. In the resulting Ring Flame Formula, his Stars rotate as a Circle, explode into numerous smaller Cores, and reconnect while the ring prevents mana leakage. World Tree spirits later add lightning to his mana and reinforce the enclosing Circle, creating the Lightning Flame and allowing him to refine both the formula and Ignition. The system supplies extreme output and supports magic above Eugene's formal Circle rank, but its more violent states still tax his body rather than granting cost-free power. (Chapters 107–113, 128–146, and 217)

During the battle with Iris, the Stars repeatedly shatter under Ignition and are remade within an expanding inner cosmos. That transformation, divine power, and Eugene's will change the White Flame Formula beyond its inherited form. By the final battle, its flames affirm Agaroth, Hamel, and Eugene together and operate as divine flames rather than ordinary Lionheart mana. The corpus establishes the effects and progression of this final state, but does not reduce it to a new numbered Star rank. (Chapters 375–381 and 610–612)

Ignition

Ignition is Hamel's decisive overdrive technique. Eugene activates it through his heart and Cores to force an explosive rise in output, and he deliberately shapes the Ring Flame Formula and Lightning Flame to withstand and intensify that process. It turns battles he cannot win at normal output into short, lethal contests, but the name describes its danger as much as its power: the technique overloads his mana organs, damages his muscles and heart, and originally gives him only about ten minutes before collapse. Combining it with Prominence or Levantein raises the strain still further. (Chapters 110–113, 130, 146–148, and 375–376)

Eugene's metamorphosis eventually removes much of the old physical recoil, allowing his transformed body to continue moving after Ignition ends. The divine surge still has a cost, however; after defeating Gavid, he temporarily loses access to divine power, and Levantein becomes far weaker without it. Against Destruction, he invokes Ignition as a final commitment—either he will kill the enemy or die—while Vermouth and Molon protect the seconds needed for activation. Its latest use remains a last-resort victory tool, not a sustainable default state. (Chapters 533–538 and 610–611)

Martial mastery and the Empty Sword

Hamel's mercenary life left Eugene proficient with swords, spears, hammers, bows, and close combat, as well as practiced at reading killing intent and changing tactics under pressure. His second life sharpens rather than replaces that foundation. He can alter a slash repeatedly within one motion, use the Cloak of Darkness to switch among weapons without telegraphing the choice, and exploit each artifact's function as part of a continuous sequence. This adaptability makes the arsenal an extension of his judgment rather than a collection of independent powers. (Chapters 14, 99, 172, 264, and 483–487)

Alchester teaches Eugene the Empty Sword, a Dragonic technique that draws ambient mana into sword-force and stacks further layers over the blade. Its ordinary weaknesses are poor durability, declining output over time, and dependence on ambient mana; Eugene compensates with the Ring Flame Formula's circulation and learns to add multiple layers without heavily draining his Cores. His output can still destroy an inadequate physical blade, and hostile environments or stronger opponents can break the layered force. Later he applies the principle to the Holy Sword, Moonlight Sword, divine flames, and Levantein, turning it into a recurring amplifier rather than a technique tied to one weapon. (Chapters 176, 299, 412, 535, and 563–564)

Magic, spirit summoning, and Prominence

Eugene begins formal magic study in Aroth and benefits from unusually precise mana perception and control. Akasha's Dragon Heart and Mer's calculations let him cast spells up to the Seventh Circle without excessive burden before he reaches that level personally, while the Ring Flame Formula lets him produce effects above his nominal rank. These aids do not simply grant every spell: he cannot cast Eighth Circle magic without the necessary attainment, and later admits that ordinary spells become less central once stronger methods are available. Wynnyd also permits a contract with Tempest, giving Eugene command of wind spirits, wind-based movement and attacks, and direct access to the Wind Spirit King when conditions allow. (Chapters 44–47, 90–118, 173–180, 217, and 516)

Prominence is the combat-support Signature Eugene develops with guidance from Aroth's Archwizards. It manifests as a wing of flame whose scattered feathers serve as remote senses, attack points, and coordinates for consecutive spatial leaps. The wing supplies explosive acceleration, can scatter destructive sunspots, and can act as a pseudo-Core that substitutes for Ignition without immediately forcing the same overload through Eugene's heart. The technique is vulnerable when an enemy disrupts its spatial coordinates, performs worse where ambient mana is scarce, and can be exhausted or destroyed under overwhelming power. (Chapters 217–220, 261–266, and 295–299)

Prominence develops alongside Eugene. Its feathers become tools for observation, defense, and coordinating attacks with his weapons; its output can be combined with Ignition, the Empty Sword, and the restorative effect of Agaroth's Ring, though those combinations remain dangerous. Once Eugene's divinity matures, Prominence ceases to be only a spell and becomes his sanctuary, overlaying his miracles on himself and Levantein. In the final war he still uses its leaps and acceleration, but he can also spread a sanctuary across a battlefield without deploying the wing itself. (Chapters 289–299, 368–376, 533–536, and 576–585)

Divine power, victory, and miracles

Eugene first awakens divine power while killing the Demon King of Fury. The Divine Sword he draws from his chest is formed from his own divinity rather than borrowed sanctity; at first, a full strike can erase a Demon King's dark power and split the sea, but he can use it only about once per day while the power replenishes. Faith in Eugene's victories subsequently flows into him as divine power. His Agaroth memories explain the origin of the throne he inherited, yet his godhood does not remain a restoration of the old God of War. (Chapters 376–381 and 406–410)

By accepting the hopes behind Agaroth's sacrifice and surpassing Gavid, Eugene turns Prominence into a sanctuary and develops miracles that impose his desired outcome on battle. His divinity sharpens intuition toward a path to victory, supports regeneration, strengthens followers, and lets him create or reshape divine weapons. After he receives the accumulated power of the Light through Levantein, he can ordain warriors, connect power to his Saints and Incarnations, and create a divine sun whose sanctuary heals wounds, reinforces mana, and lets believers fight without tiring. These effects depend on faith, available divine power, and Eugene's ability to sustain the miracle. (Chapters 487, 532–545, 571, and 576–577)

The final battles establish both the scale and limits of Eugene's godhood. Incarceration's darkness can suppress his sanctuary and break his Divine Sword, Ignition's backlash can temporarily seal away divine power, and contact with Destruction erodes both his power and existence. Eugene overcomes these limits through cooperation rather than solitary supremacy: the Saints make the Light's reserves manageable, Sienna's divinity and Noir's Demoneye expand shared miracles, Molon carries his power as an Incarnation, and Vermouth opens the final path. Eugene's latest divinity is identified as victory, fueled by the world's will to continue rather than by war for its own sake. (Chapters 584–595 and 603–612)

Moonlight Sword and Levantein

The Moonlight Sword supplies a destructive light that erases dark power, but its power is item-derived and initially unsafe. During the fight with Iris, the blade drains Eugene's mana against his will, prevents him from retracting its light, damages his Stars, and begins eroding his consciousness. Incarceration's chains interrupt the rampage before it destroys both Iris and Eugene. Eugene later believes his evolved White Flame Formula and divine power can balance the sword, but control remains something he must actively establish rather than an innate immunity. (Chapters 367–374 and 382–386)

Levantein is the Holy Moonlight Sword created when the Light reforges the Holy Sword, Moonlight Sword, Demon Spear, Annihilation Hammer, and Eugene's Divine Sword into one glass-like weapon. It carries the component weapons' powers, serves as Eugene's Divine Sword without the former limit on individual summons, and channels flames lethal to Demon Kings' immortality. Its early output is so great that Eugene needs his sanctuary and Ignition to avoid self-immolation, and even then divine backlash remains. With greater mastery and resonance through the Saints, he changes its shape, multiplies it through miracles, combines it with the Empty Sword, and uses it as the central weapon against Noir, Incarceration, and Destruction. (Chapters 532–545, 560–565, and 577–612)

Power progression

Relationships

• Vermouth Lionheart: Hamel's admiration, resentment, and rivalry with Vermouth are inseparable from their loyalty to one another. Eugene spends much of his second life questioning Vermouth's pact and secrecy, but ultimately rejects both condemning him without the truth and allowing him to sacrifice himself again. Rescuing Vermouth makes their final victory a restoration of their friendship rather than another debt paid through death. (Chapters 71, 312, 546, 580, and 603–613)
• Sienna Merdein: Sienna and Hamel's constant quarrels conceal deep trust and attachment. Her refusal to release his soul makes Eugene's return possible, while his determination to kill Raizakia frees her from confinement. Their later partnership joins his martial force to her magic and divinity, and Eugene eventually asks her to share the peaceful life they preserved. (Chapters 1, 104–113, 287–315, 550–568, and 603–625)
• Anise Slywood: Anise was Hamel's healer, critic, and confidante. Living within Kristina allows her to reunite with Eugene and resume challenging his recklessness, but their bond grows beyond nostalgia as she repeatedly shares the backlash of his powers and chooses a future with both him and Kristina. (Chapters 196, 204–205, 488, 504, and 576)
• Kristina Rogeris: Eugene initially distrusts Kristina's devotion to the Light and struggles to distinguish her from Anise's presence. Their travels and battles make Kristina a partner in her own right: she supports his divine power, confronts his willingness to die, and joins Anise and Sienna in accepting his proposal. (Chapters 83–116, 183–206, 245, 504, 569–612, and 624)
• Molon Ruhr: Hamel mocks Molon's simplicity but trusts his courage and strength without reservation. Eugene's return breaks through Molon's exhausted isolation at Lehainjar; later, Eugene ordains him as his Incarnation and Greatest Warrior, while still treating him as the same companion with whom he can argue, fight, and drink. (Chapters 229–248, 404–405, and 581–613)
• Gerhard Lionheart: Gerhard is Eugene's biological father and the person whose consent Eugene places above the advantages of main-family adoption. Even with the memories of Agaroth and Hamel, Eugene regards Gerhard's care from infancy as an unquestionable paternal bond. (Chapters 2–28, 458, 618, and 625)
• Gilead Lionheart: Gilead recognizes Eugene's ability, adopts him, and opens the main family's training and relics to him without demanding that Eugene replace Gerhard. Eugene respects him as patriarch and adoptive parent, while his achievements repeatedly leave Gilead proud and overwhelmed. (Chapters 16–30, 74–90, 208–216, 237–238, 458–491, 538–539, and 618–625)
• Cyan Lionheart: Cyan begins as a defeated rival but becomes Eugene's brother through years of sparring and shared growth. Eugene's harsh refusal to indulge Cyan's despair helps turn their rivalry into discipline, and by the epilogue Cyan can question Eugene about marriage with the familiarity of family. (Chapters 4–25, 75, 170–179, 221–227, 390, 491–498, and 597–624)
• Ciel Lionheart: Ciel's childhood teasing and rivalry deepen into loyalty and unreturned romantic feeling. Her insistence that Eugene remains Eugene regardless of Hamel or Agaroth gives him one of the clearest affirmations that his present identity is not invalidated by reincarnation. (Chapters 4–14, 342–347, 373–386, 529, and 599–625)
• Mer Merdein: Mer begins as the familiar guarding Sienna's Witch Craft and becomes Eugene's magical assistant and constant companion within the Cloak of Darkness. He protects her, depends on her calculations, and ensures that rescuing Sienna also restores the creator Mer has waited centuries to meet. (Chapters 44–57, 117–145, 176–208, 373–430, and 615–625)
• Noir Giabella: Noir is a recurring enemy whose fascination with Hamel develops into love for both Hamel and Eugene, complicated by their earlier lives as Agaroth and the Twilight Witch. Eugene never abandons his intention to kill her, but her death wounds him precisely because he accepts that their bond was real. (Chapters 96, 252–256, 385–399, 492–497, 550–568, and 620–625)
• Demon King of Incarceration: Incarceration is the enemy Hamel failed to defeat, the keeper of truths behind the Oath, and the power that repeatedly tests whether Eugene will accept fatalism. Eugene defeats him without accepting his approval, though they later cooperate long enough to end Destruction and save Vermouth. (Chapters 238–239, 546, and 581–594)

Items

• Holy Sword Altair: The sacred sword recognizes Eugene as the Hero and becomes an early channel for the Light; its radiance is later reforged into Levantein. (Chapters 90, 190–202, and 532)
• Moonlight Sword: Eugene inherits this sword of Destruction from Vermouth's legacy. Its erasing moonlight is among his strongest weapons, but its rampage against Iris nearly consumes him before he learns to balance it with his other powers. (Chapters 18–19 and 367–386)
• Storm Sword Wynnyd: Eugene selects Wynnyd from the Lionheart treasure vault. Its blessing grants wind spirit magic and provides the medium through which he contracts and summons Tempest. (Chapters 18–19, 90, and 177–180)
• Devouring Sword Azphel: A demonic sword in Eugene's rotating arsenal, used when its ability to consume power suits the opponent. (Chapters 68 and 99)
• Thunderbolt Pernoa: Eugene uses Pernoa as a lightning weapon whose mana demand is reduced by his Lightning Flame, allowing repeated ranged attacks within his mixed-weapon tactics. (Chapters 18, 146, and 264)
• Dragon Spear Kharbos: A spear capable of releasing a dragon's Breath, deployed as one part of Eugene's rapid weapon changes and combined bombardments. (Chapters 18, 99, and 264)
• Demon Spear Luentos: A relic of a fallen Demon King whose Spear Forest ability Eugene wields through the weapon; its power is later incorporated into Levantein. (Chapters 19, 264, and 532–533)
• Annihilation Hammer Jigollath: Eugene uses the hammer's destructive force despite the danger of its demonic origin. Its ability to shatter and explode obstacles survives within Levantein. (Chapters 19, 146, and 532–534)
• Cloak of Darkness: The cloak provides the extradimensional storage that lets Eugene carry and switch among his large arsenal; it also houses Mer and becomes a visual symbol closely associated with him. (Chapters 48, 99, 146, and 532)
• Ring of Agaroth: This divine artifact accelerates recovery and amplifies miracles. Eugene uses its restoration to survive combinations such as Prominence and Ignition, although it cannot remove the danger of pushing those techniques beyond his body's limits. (Chapters 190–202, 264, 299, and 426)
• Akasha: Sienna's Dragonheart staff supports Eugene's spell analysis and casting while Mer supplies calculations. It accelerates his magical growth and helps him develop Prominence before his divine powers eclipse ordinary spellcasting. (Chapters 45–47, 116–130, 159, and 516)
• Levantein: The Holy Moonlight Sword is the final synthesis of Eugene's sacred, destructive, demonic, and divine weapons. It becomes his principal blade from the duel with Gavid through the battles against Noir, Incarceration, and Destruction. (Chapters 532–545 and 560–612)
