Upa Bullenon

Upa Bullenon is a Grand Duke known as the Destroyer, a rival claimant whose black-hole magic, enormous creature armies, undead expertise, and secret control of Gustarte make him a central threat on Earth. He repeatedly rebuilds after Randalph Brigsiel cuts apart his faction, nearly defeats Ariel Diablo at Greenwich Observatory, and is finally decapitated by Ariel after the Hope explosion leaves both armies devastated.

Biography

Pride, punishment, and a new enemy

Upa enters the first Demon World Auction accustomed to having his rank obeyed. When Randalph injures one of his demons, Upa demands an explanation, sends Pakan Griolli to silence the unaffiliated Earl, and allows the quarrel with the dark spirits to escalate. His refusal to accept Spirit World authority gets his faction banned from the auction for three years, turning wounded pride into a material disadvantage while Randalph gains the relationship and advance information Upa once used. (Chapters 27–32)

Randalph exploits that opening by attacking Upa's widely scattered territory and the subordinates who receive only limited contact from their grand duke. Adol's dungeon in Japan falls, Maxium's temporary army strikes two Chinese dungeons, and Upa loses several demons without immediately identifying the culprit. The damage does not destroy his faction, but it forces him to recover while Ariel attacks him and teaches Randalph that Upa becomes more dangerous, not less, once prolonged pressure gives him reason to fight indirectly. (Chapters 48–107)

The smokescreen at the auction

By the next major auction, Upa appears impatient because his empty seats expose recent losses and Ariel openly mocks him. He needs powerful creatures to restore the balance, yet his anxious bidding becomes a deliberate smokescreen: after losing Mago, he lets rivals focus elsewhere, directs his faction's purchases, and monopolizes much of the later inventory. Randalph recognizes the deception and spends specifically to prevent Upa from rebuilding without resistance. (Chapters 114–120)

Upa later returns with eighteen demons and one of the largest point reserves, using faction members to raise the prices of his own individual-auction goods. He fights for a hydra and Shilla's corpse because creatures and undead fit his route to power, but Randalph outbids him for both. When Ariel proposes recognizing Randalph as the new fourth grand duke, Upa alone refuses; the system and the other two grand dukes overrule him, converting a rival he once treated as an upstart into an acknowledged equal. (Chapters 152–166)

The war with Ariel and the stolen god

Upa's territorial strength grows across South America while his war with Ariel forces both sides into a temporary truce when the sacred zone appears. Maxium acts as a counterweight against Upa's advantage, so Upa sends subordinates to raid and contain him. The campaign reveals a new weapon: the magician of the moon, later identified as Gustarte, whom Upa assigns to Arend with a single overriding command and enough power to maim a bone dragon and nearly destroy Maxium's intervention. (Chapters 189–195)

Gustarte's rigid obedience becomes the weapon's weakness. Randalph and Maxium lure him away by exploiting his order to destroy the bone dragon, and Randalph damages his body until the resulting explosion sends him into the Reverse World. Later evidence establishes that Upa did not independently overpower a god: dark spirits accessed Gustarte's world through a crack, and Death Bringer's system enabled the control. Upa loses his secret advantage when Chrisley attacks its keeper and Randalph captures the damaged god. (Chapters 195–201 and 227)

The grand-duke gathering and the angel hunt

Randalph's invitation reaches Upa inside a dungeon modeled after his Demon World castle. Upa threatens the messengers, destroys the paper as its taunts anger him, and nevertheless accepts because he understands that the gathering concerns the war's balance. He then sends a king wyvern to follow them toward Ariel's territory, showing that his temper does not prevent surveillance. At Greenwich Observatory he brings the numerical strength that years of recovery and creature accumulation have produced. (Chapters 199–202)

When angels attack, Upa openly spends that strength. Black typhoons and a black sun erase angel units, and he personally consumes an angel after breaking through her holy protection. His hundreds of thousands of creatures give him the largest army on the field, but the display also makes him a target: Randalph directs his own small force against Upa's weaker rear, Maxium captures Upa-aligned dungeons while the grand duke is committed, and Ariel's elite army meets him near the Ark. (Chapters 210–220)

Victory denied at Greenwich Observatory

Upa expects numbers to overcome Ariel's smaller faction, but her silver knights share damage and strength well enough to stall him while angels and Randalph attack his formation. He answers by combining black spheres into a vast pull that disregards friend and foe, because killing Ariel matters more than preserving every creature in range. Ariel holds a slight advantage in their personal duel, yet Upa's army steadily exhausts her knights and eventually lets him knock her down. (Chapters 219–224)

The advantage comes at an unsustainable cost. Randalph's attack creates a gap, Ariel destroys roughly half of Upa's remaining power, and days of combat leave both grand dukes heavily wounded even as Upa stands last with about fifty thousand creatures. He summons dozens of typhoons for the finishing blow just as Hope detonates. The blast eliminates their surviving armies; Ariel endures, decapitates Upa, and leaves his head to fall into Randalph's crater. His dungeons and achievements are then divided among demons and human Awakened, while the forces he left in the Demon World are later confirmed collapsed. (Chapters 224–235)

Appearance and personality

The corpus explicitly gives Upa red eyes but does not provide a stable description of his hair, horns, clothing, height, or build. His presentation instead comes through posture and surroundings: he looks down from a huge bone chair, fills his recreated castle with black armor and weapons, and uses threatening creatures and controlled heat to make visitors feel his displeasure before he speaks. (Chapter 200)

Upa is arrogant, self-righteous, vindictive, and unwilling to perform magnanimity. Insults provoke visible anger, and he treats subordinates according to strength and utility rather than sympathy. He is not merely impulsive, however. His later auction anxiety is an act that conceals a purchasing strategy, he uses scouts and followers to gather information, and his large-force tactics nearly defeat Ariel. Pride repeatedly shapes those calculations, making victory over a rival more important than preserving every resource. (Chapters 27–71, 115–120, 161–162, 200–202, and 219–224)

Abilities and powers

Upa is a grand-duke dungeon master whose demonstrated power combines gravitational black spheres, large-scale typhoon manipulation, physical combat, spatial control within his dungeon, undead specialization, and a creature army built for attrition. The corpus calls him the Destroyer but does not present a full system profile or origin history for his personal magic.

Black spheres, black sun, and typhoon weapon

Upa's patented black spheres behave like localized black holes, pulling in surrounding matter with force that can drag structures when fully developed. He can combine many spheres into a black sun that steadily absorbs nearby targets or into a black typhoon large enough to distort space and erase angels across a mountain-moving sweep. The source does not name the power supply, casting sequence, maximum range, or duration, so those mechanics remain unknown. (Chapters 27–32, 210, and 219)

He controls the typhoon as a weapon, holding its base like a sword, redirecting its path, and dividing it into hundreds or thousands of blades. Against an angel protected by holy light, he rides one blade into close range, pushes a hand through the barrier while the contact burns him, darkens the protection, and consumes the angel. The technique is immensely destructive but not selective: his largest black hole pulls allies and enemies alike, and Ariel's chaos sword is strong enough that she chooses to meet it directly rather than flee. (Chapters 210 and 219)

Physical force and dungeon authority

Upa is dangerous at close range as well as at a distance. He physically penetrates an angel's protection after his magic weakens it, remains standing after days against Ariel, and can still summon dozens of typhoons while badly wounded. Ariel has the slight advantage in a direct duel and ultimately kills him after Hope, demonstrating that endurance and army support do not make him unbeatable once his forces and defenses are stripped away. (Chapters 210 and 219–225)

Inside his dungeon, subtle finger movements raise the ambient temperature around guests, and more than a thousand advanced creatures respond to his mood. Randalph remembers that a truly transcendent Upa can summon the giant castle Bullenon, but also states that the Earth-era Upa has not reached the qualification needed to do so. His dungeon therefore imitates that Demon World castle through construction and decoration rather than demonstrating the transcendent summoning itself. (Chapters 200 and 210)

Undead expertise and massed armies

Upa specializes in undead creation and is judged better at it than Pandemonium when both bid for Shilla's corpse. The corpus does not isolate his crafting method, production time, or a named undead technique, and he never acquires the corpse in that auction. His wider military method is clearer: trusted dukes, dungeon territory, advance purchases, strong creatures, and enormous numbers let him sustain wars that would exhaust a smaller elite force. (Chapters 27–71, 119–120, and 161–162)

That approach has structural weaknesses. Distant subordinates can lack direct contact, opportunistic vassals may betray him, and a mass army cannot answer every attack while its commander is fixed on Ariel. Randalph exploits those limits by killing demons from below, using Maxium against remote dungeons, and opening a weak point in Upa's rear at the Ark. Numbers win Upa the immediate attrition battle, but their concentration makes the Hope explosion ruinous. (Chapters 48–107 and 193–226)

Control of Gustarte

Gustarte is an external controlled weapon rather than an innate ability. The god's damaged ego and Death Bringer's system allow Upa's faction to impose simple commands and a seal, with a watcher required because leaving him unattended is dangerous. Under the order to destroy a bone dragon, Gustarte creates moving night, fires starlight that absorbs dragon breath, regenerates from extreme damage, and refuses to change targets even while Randalph attacks him. (Chapters 193–197)

The control is powerful but inflexible. Conflicting priorities cause Gustarte to hesitate, and the order's literal focus lets Randalph draw him away from Upa's forces. Chrisley later kills the assigned keeper and captures the god while Upa is occupied at Greenwich Observatory. Gustarte's restored testimony reveals that dark spirits and the system, not Upa's personal dominance, made the enslavement possible; by Upa's final battle, he no longer has access to this weapon. (Chapters 197–201, 211–213, and 227)

Power progression

Relationships

• Randalph Brigsiel: An unaffiliated Earl Upa initially tries to discipline, then an acknowledged grand-duke rival who dismantles his faction, captures Gustarte, and engineers the opening that leads to his death.
• Ariel Diablo: His longest direct rival; their wars span the Demon World and Earth, and Ariel decapitates him after their Greenwich battle and the Hope explosion.
• Pandemonium: A rival claimant with related undead interests who sometimes benefits from Upa's conflicts but competes for the same throne and auction resources.
• Okullos: A fellow grand duke whose taboo growth changes the balance and whose death helps force Upa to confront Randalph's elevation.
• Pakan Griolli: One of his dukes, first used to confront Randalph and later abandoned after the auction incident makes him a liability.
• Gustarte: The intermediate god made into Upa's secret weapon through the dark spirits and Death Bringer's system; the rigid control fails when Randalph exploits its command.
• Maxium: The commander Randalph repeatedly uses to damage Upa's remote dungeons and prevent his numerical advantage from becoming decisive.
