Background / History

Ancient Wars and Rule over Humanity

Leins lived through the ancient war between magical beasts and humanity’s God Level experts. He remembered Aguste Philia’s attempt to create a perfected bloodline by combining the powers of gods and fallen God Level experts, including the battle in which Philia killed a third of the God Level magical beasts sent to intercept him 111 112.

He was originally the sole God Level magical beast assigned to oversee the Human Continent. Xiaotian, the Two-Headed Frost Wolf, began as his Demigod subordinate and later advanced to God Level, leaving two God Level beasts suppressing humanity. Leins considered Xiaotian weaker but acknowledged that his greater potential might eventually have allowed him to surpass Leins 111.

Leins also slaughtered dwarven experts in an encounter witnessed by the young Yagansi. The dwarves fell to his golden flames within three moves; the resulting fear continued to obstruct Yagansi’s advancement to Demigod 118.

Battle with Issui

After killing Xiaotian, Issui targeted Leins to prevent retaliation against human civilians. Xiliya warned that Leins had centuries of God Level experience and estimated him to be at least half again as powerful as the recently advanced wolf 110.

Leins already knew Issui had killed Xiaotian but chose to confront him himself. During their battle, he recognized similarities between Issui’s Flame Body and the ability of a fallen magical beast. Learning that Issui descended from Aguste Philia convinced him that the Perfect Bloodline was too dangerous to leave alive 111 112.

When Issui absorbed his golden flames, Leins switched to sound attacks. He shattered and repaired space while attempting to expose Issui’s hiding place, then returned to his beast form after Issui’s crystallized earth defenses resisted his sonic attacks. His innate spell, Devouring Heaven and Earth, swallowed Issui along with vegetation, soil, and clouds from the valley 113 114 115.

Swallowing Issui gave the ninja the opportunity he needed to use the Ice Soul Seal from inside Leins’s stomach. The first attempt failed. Leins threatened to self-destruct rather than become a weapon against his own race, but Issui completed a second attempt before he could do so. The successful seal placed Leins’s soul under Issui’s control 116.

Service to Issui

Leins asked what would become of the magical beasts. Issui explained that he intended to eliminate three God Level beasts while preserving the rest as opponents for cultivators after two worlds merged. Although Leins recognized that his race was still being used, he thanked Issui for allowing it to survive and accepted his service more willingly 116.

He became Issui’s flying mount, caught up with Xiliya, and carried them back toward the Radiance Kingdom. His public obedience—and a demonstration of his God Level pressure—helped convince the elven and dwarven envoys that Issui truly possessed the means to oppose the magical beasts 117 118 119.

Elven Campaign and Negotiations

Leins helped uncover Nicole’s parentage after she endured the residual force of his charge without injury. He suspected magical beast ancestry, then identified her swaddling as hide from the Golden Behemoth Stosa Beckett. His knowledge of Stosa and Annie supported the identification of Nicole as their daughter 123 124 128.

During the campaign against the beasts threatening the elves, Leins explained Slick’s abilities and later recognized the aftermath of his soul detonation. He also warned the allies about Jiligao Li’s ability to transport himself and others through darkness 132 142 143.

When Stosa confronted him over his changed allegiance, Leins stated that they were no longer comrades because he now had a master. Issui interrupted to call Leins a dependable comrade rather than a subordinate. During the ensuing negotiations, Leins neutralized Jiligao Li’s covert sound attack on Issui 144 145.

Battles in the Shinobi World

Leins carried Issui through the air in pursuit of Deidara during the mission to recover Gaara. During Pain’s invasion of Konoha, he enlarged his body and charged a giant summoned chameleon, sending it flying 156 208.

Before facing four reanimated Kage, Issui stationed Leins outside the battlefield with orders to extract him if necessary. Leins later rescued him after Kabuto triggered the soul-freezing punishment associated with the Eye of Heaven’s third stage 234 241.

Leins forced Kabuto to explain the condition and reveal that a woman’s tears could save Issui within five minutes. After branding Kabuto with the Blazing Liger Seal, he rushed Issui to the Allied Shinobi Forces camp. Hinata’s tears then began sinking into Issui’s forehead 241.

Appearance

• Human form: A large man with golden hair, a whiskered face, fierce brows, and a long golden beast-hide robe 111.
• Beast form: A lion’s head and tiger’s body, with golden light shining from his eyes and golden flames beneath his feet 115 117.
• Battle size: More than 50 meters tall and over 100 meters long when first revealed; later described as over 200 meters long while confronting Kabuto 115 241.
• Riding size: Can shrink to a little over three meters tall and five meters long 117.
• Later condition: Gains weight while living on the food and drink Issui provides 234.

Personality

Leins initially regards domination as the natural privilege of the strong. He defends humanity’s subjugation by arguing that humans would reverse the arrangement if they possessed greater power. His contempt extends to opponents beneath his level: he lets Xiliya leave the valley because a mere Demigod does not interest him 111 116.

His confidence rests on centuries of combat experience, but he is not careless about unfamiliar threats. He recognizes Issui’s substitutions, deduces the limitations of Flame Body, and worries that repeated concealed attacks could gradually injure him. He also avoids unnecessarily shattering space because repairing the damage is costly 112 113 114 115.

Leins is proud and sensitive to humiliation. Issui’s successful defenses embarrass him, while Nicole’s insistence on treating him as a cute puppy provokes a genuine attack. He later avoids her teasing rather than risk further indignity 115 122 123 126.

His loyalty to Issui begins through coercion: the Ice Soul Seal gradually reshapes his soul toward exclusive obedience. Nevertheless, his concern for the survival of the magical beasts remains evident, both in his gratitude for Issui’s restraint and his sadness at their decline 116 142.

Abilities & Skills

God Level Physique and Combat Experience

• Standing among magical beasts: Ranked third among the surviving God Level magical beasts discussed during his fight with Issui, behind the two leading beasts on the Magic Beast Continent 112.
• Speed: Moves quickly enough that Issui initially sees only an afterimage rather than his moving body 111.
• Physical strength: Even the residual force of his checked charge is sufficient to send a high-ranking Legendary magical beast flying 123.
• Power suppression: Can conceal his God Level pressure, then release enough force to crush the elven and dwarven envoys to the floor 118.
• Human-form limitation: His human form possesses only two-thirds of his true form’s strength 115.
• Tailed Beast comparison: The narration places him at least on the Nine-Tails’ level, potentially considerably higher, but below the Ten-Tails. Kabuto believes he cannot resist him even with Sage Mode and all his trump cards 241.

God-Devouring Golden Flame

His fire mutated into golden flames upon reaching God Level. Despite being his best-known power, fire is the weakest of his three developed specialties 110 113.

• Flame coating: Covers his body in golden fire for battle 112.
• Crushing Flame Palm: Injects flame energy into the ground and detonates it, rupturing the terrain and forcing concealed enemies to emerge 112.
• Golden Flame Secret Art—Clone God-Slaying Slash: Surrounds an opponent with his main body and three shadows. Each manifests two golden-flame blades, producing eight simultaneous slashes 112 113.
• Limitation against Issui: Issui’s Flame Body can absorb and merge with the golden flames, making flame attacks counterproductive in that matchup 113.

Sound Manipulation

Leins identifies sound as his second-strongest developed power. His waves can explode on contact or penetrate a surface to damage what lies inside; refusing to listen does not prevent them from working 113 114.

• Defensive application: Neutralizes Jiligao Li’s covert sound attack with a spoken command 145.
• Vocal requirement: Must be able to open his mouth and produce sound to attack 114.
• Defensive counter: Sufficiently dense, layered crystallized earth can stop his sonic attacks 115.
• Spatial control: His sound can both break and repair space; the narration also credits him with the ability to lock it down 114.
• Repair cost: Restoring shattered space consumes three times the energy required to break it. If spatial turbulence grows too extensive, he can no longer contain it 114.

Wind Power

• Leins names wind as his strongest developed specialty, above sound and golden flame. He associates the lion side of his race with sound and the tiger side with wind 113.
• No named wind attack is shown in the provided encounters.

Devouring Heaven and Earth

An innate spell distinct from the fire, sound, and wind powers Leins developed himself 115.

• Produces enormous suction from his open jaws, swallowing Issui, an entire layer of the valley floor, vegetation, and some overhead clouds 115.
• Allows him to bypass the earth defenses Issui uses against sound attacks 115.
• Creates an opening for an opponent who survives inside him: Issui uses that position to apply the Ice Soul Seal 116.

Transformation and Aerial Movement

• Can change between humanoid and beast forms and adjust his beast form’s size 111 115 117.
• Runs through the air without wings, providing Issui with fast, stable transportation 117 156.
• Reaches the Allied Shinobi Forces camp in less than ten seconds while carrying the incapacitated Issui 241.

Blazing Liger Seal

• Projects a golden-flame character meaning “seal” from his forehead onto a target’s forehead 241.
• Drains most of Kabuto’s mental energy and some physical vitality, leaving him screaming, collapsed, and convulsing 241.

Historical and Magical Knowledge

• Identifies the origins of Issui’s Perfect Bloodline through memories of Aguste Philia and the ancient war 112.
• Explains other powerful beings’ abilities, including Avril’s elemental resistances, Slick’s three Profound Mysteries, and Jiligao Li’s Darkness Aura 130 132 143.
• Recognizes Stosa’s hide and detects the familiar magical beast heritage within Nicole 123 124.

Ice Soul Seal Bond

• Issui controls Leins’s soul through the Ice Soul Seal, which gradually makes him loyal to Issui alone 116.
• The bond links their survival: Leins states that if Issui’s soul perishes, he will die as well 241.

Relationships

• Issui — Former enemy, then master and rider. Their bond is imposed through the Ice Soul Seal, though Issui later explicitly recognizes Leins as a comrade 116 144.
• Xiaotian — Former Demigod subordinate who became a fellow God Level overseer of the Human Continent. Leins acknowledged his potential despite considering him weaker 111.
• Nicole — Initially enrages him by calling him a puppy. Her unusual strength leads him to investigate her heritage; he later tolerates her partly because she is Stosa’s daughter and close to Issui 122 123 126.
• Stosa Beckett — Former comrade and a stronger God Level beast. Their allegiances diverge after Leins becomes Issui’s mount 124 144.
• Jiligao Li — Former ally whose covert sound attack Leins counters during negotiations 144 145.
• Uriala — Fellow magical beast bound to a new master. The two recognize their shared situation after her submission to Avril 142.
• Yagansi — A witness to Leins’s slaughter of dwarven experts. His lasting terror of Leins obstructs his cultivation 118.
• Kabuto — Enemy whom Leins intimidates into revealing how to save Issui, then brands with the Blazing Liger Seal 241.
