Background / History

Simu awakens in a black-purple underworld and meets Lord Jashin. When offered a choice between becoming a cult follower or suffering humiliation, he feigns devotion and promises to offer the entire Shinobi World to Jashin. Jashin grants him an Immortal Body, while postponing the promised Jashin Ritual. 1

He reincarnates as the Blood Pool beneath the Jashin Cult’s Divine Statue. His true body is the pool itself; the humanoid Simu encountered by others is a clone sustained by life energy. His immortality belongs to the Blood Pool rather than these disposable clones. 3

After defeating Hidan and absorbing his genetic material, Simu is accepted by the Cult Leader as a God Child. He immediately begins using the Womb of the Primordial Creator to analyze genes, cultivate Jashin Race variants, and expand his surveillance network around cult headquarters. 3 13

Following the destruction of the Sakamoto Trading Company and conflict with Yugakure ninja, Simu’s activities dramatically raise the cult’s reputation and advance his system to Level 2. He subsequently permits the Cult Leader to possess a clone body in order to study Living Corpse Reincarnation, surviving the soul attack due to his enhanced mental power. 37 39

After facing Orochimaru’s Snake Clone, Simu recovers its corpse for analysis. His later research yields broad ninja-gene categories, RC Cells, and a deeper understanding of chakra, allowing him to create and modify increasingly advanced Jashin Race organisms. 42 43 45 46

Simu raids Orochimaru’s laboratories and obtains data on artificial chakra-nature modification, natural-energy drugs, Artificial Sage Mode, and hundreds of test subjects. There he rescues and begins studying Uzumaki Rii, whose Uzumaki constitution allows her to survive exposure to Natural Energy far beyond ordinary subjects. 49 50 51 53

After relocating his true Blood Pool to a hidden underground fissure on the Land of Rivers border, Simu develops Blood Pool Clones and Crow Clones. This decentralizes his production and survival, allowing him to operate through multiple bodies while concealing the location of his main body. 57

He recruits Jugo after discovering that Jugo’s body naturally absorbs and contains Natural Energy without Orochimaru’s drugs. Alongside Rii and the Harpy Xianai, Jugo becomes part of Simu’s developing network of enhanced followers and experimental subjects. 60 74 75

Simu establishes churches that grant apparent miracles in exchange for bodies, souls, and obedience. By deliberately encouraging dependence, greed, and religious fervor, he turns townspeople into resources and expands Jashin’s influence. The growing movement eventually attracts Akatsuki’s attention. 62 63

After testing Nagato’s abilities, Simu enters a transactional partnership with Akatsuki. He agrees to support its Tailed Beast campaign and help provoke a world war in exchange for intelligence, rare ninjutsu, Demonic Statue of the Outer Path material, and Tailed Beast samples. 70 72 73

Simu expands into the Land of Wind through the Red Spider Lily Merchant Guild, Blood-Spirit Worm-based Military Ration Pills, desert-adapted Jashin races, and the Broodmother Network. His operations reshape the local economy, spread Jashin worship among impoverished settlements, and ultimately create a strategic relationship with Sunagakure. 111 115 119

Working with Orochimaru, Simu gains access to Hashirama Cells and develops Wood Release-compatible bodies. He enters Konoha through the identity of the Wood Release child “B,” joins Root, and exploits Danzō’s conditioning attempts while rapidly mastering the organization’s Wood Release techniques. 158 159 165 167 182 183

During his Konoha operations, Simu gathers clan records, bloodline data, forbidden techniques, and Sharingan samples. He studies the Hyuga Clan’s hidden Byakugan reserve, manipulates Uchiha-Konoha tensions, and develops Uchiha clones capable of using transplanted Mangekyō Sharingan. 183 186 208 247

Through repeated spiritual encounters with Sasuke, Simu confronts Indra and learns the history of the Divine Tree, Ten-Tails, Kaguya, the Sage of Six Paths, and the reincarnating conflict between Indra and Asura. He later secures Indra’s reluctant cooperation by promising to revive Sasuke and locate Asura’s reincarnation. 304 316

Simu captures, divides, and recreates portions of multiple Tailed Beasts through Yin-Yang Sealing Techniques. His newly born Little Saiken and Little Isobu become his summoned creatures, while his broader research turns Tailed Beast Chakra, the Demonic Statue, and the Ten-Tails into the central focus of his long-term plans. 287 314 315

Appearance

Simu commonly manifests through a pale, black-haired humanoid clone with black-rimmed glasses. He usually appears composed and well dressed, often adjusting his glasses before making a cutting remark or using an ability. 2 42

• Pale complexion and black hair pressed against his skin after emerging from the Blood Pool. 2
• Black-rimmed glasses, a habitual part of his appearance and mannerisms. 2 42
• His true form is a temple Blood Pool rather than a human body. 3
• Can manifest insectoid Kagune, black exoskeleton armor, spider silk, and steel-feathered wings from his clone body. 7 12 23 42
• Uses multiple public identities and bodies, including the crow-like “Mr. Crow,” merchant Kimura, and Root operative B. 57 165 208
• His Ninja Clones can be engineered with five elemental natures, Yin-Yang Release, sealing aptitude, Space-Time Ninjutsu, and specialized biological organs. 97
• His Uchiha-derived clones can possess ordinary Sharingan or transplanted Mangekyō Sharingan, allowing their eyes to change from black to red only when activated. 208 226 292
• Can manifest increasingly advanced Susanoo forms, including armored third-stage Susanoo and fourth-stage Black Tengu Armor. 304 314 326

Personality

Simu is observant, calculating, and intensely curious. Entering an unfamiliar world, he prioritizes gathering intelligence about chakra, ninjutsu, politics, and the Shinobi World’s hidden history before acting openly. 8 9

He is manipulative and pragmatic. His outward loyalty to Jashin is entwined with his desire to gain resources, reputation, and freedom to develop the Jashin Race. He uses Hidan, cult sacrifices, and outside conflicts as opportunities for research and expansion. 10 13 37

Simu does not consider himself human and explicitly rejects human moral expectations. He can recognize courage in people such as Shiraishi Mori, but he refuses to save others merely because he has the power to do so, instead viewing crises as opportunities to observe change, collect data, or provoke evolution. 3 34 35 36

His fascination with unknown phenomena can override caution. Rather than retreating from dangerous research subjects such as Orochimaru’s techniques, RC Cells, or natural energy, he studies them directly—even amputating his own petrified hand with little concern after testing natural energy. 43 45 50

Simu presents himself as gentle, refined, and helpful when doing so serves his goals. He gives Rii clothing and reassurance after rescuing her, treats Gaara with unusual warmth, and establishes churches around tangible aid, but these actions coexist with his readiness to turn recipients into subjects, property, or followers. 51 53 62 63 111

He sees social unrest as a useful laboratory condition. Simu cultivates economic dependence, religious extremism, political conflict, and warfare because suffering and chaos increase Jashin’s reputation, weaken rival powers, and create opportunities to acquire specimens and knowledge. 63 180 247

Although confident in his own abilities, Simu is not recklessly confrontational. He studies powerful opponents such as Nagato, Jiraiya, Orochimaru, Itachi, Minato, Indra, and the Tailed Beasts before committing to a larger plan, often using clones to preserve his true body and gather data. 70 89 90 215 227 286 304

Abilities & Skills

Womb of the Primordial Creator

Simu’s central system ability allows his Blood Pool body to devour living creatures, analyze their genes and abilities, combine genetic traits, and create new Jashin Race beings that naturally obey him. 3

• Creates humanoid clones, Kagune, Ravens, Black Beetles, ninja-derived organisms, and other engineered lifeforms. 13 37 45
• Can reproduce ninja bodies and grant elemental chakra traits by grafting relevant genetic segments. 45 46
• Requires energy; large-scale production can drain his reserves and consume life force. 13
• His Immortal Body lets him endure this cost so long as Jashin has not fallen. 13 37
• Later produces specialized bloodline bodies, including Wood Release bodies, Uchiha clones, Hyuga-derived subjects, and bodies compatible with transplanted dōjutsu. 159 208 247
• Can create artificially separated Tailed Beast entities by combining Tailed Beast Chakra with advanced Yin-Yang Release and sealing. 287

Immortal Body

Jashin’s blessing makes Simu effectively immortal while Jashin remains alive. The blessing is tied to Simu’s true Blood Pool body, not necessarily to individual clones. 1 3 37

• Regenerates severe damage to his manifested body, including deep wounds inflicted by Orochimaru’s Wind Cutter Technique. 42
• Allows him to use life force aggressively for mass creation without permanent death. 13
• Clone bodies remain expendable and can be replaced with new life energy. 3
• His distributed Blood Pool Clones greatly reduce the danger posed by the destruction of any single base or manifested body. 57
• Engineers clone bodies with relocated vital points, allowing him to survive wounds that would be fatal to ordinary humans. 227

Kagune

Simu describes his Kagune as inherited parts of Jashin’s physical form. They serve as his primary weapons, defenses, and biological tools. 7

• Weihe: Centipede — A massive, bladed centipede tail growing from his spine. 7
• Rinkaku: Mantis — Sharp scarlet mantis-like limbs capable of rapidly severing opponents. 3 7
• Koukaku: Spider — Eight spider-like appendages that produce silk, including silk used to bind Hidan or stitch wounds. 7 23
• Koukaku: Ant-Man — Hardened exoskeleton armor capable of withstanding blades and explosions. 12
• Ukaku: Sword Raven — Steel-feathered wings that form enormous blade-like weapons; they slice Orochimaru’s serpent body in half. 42
• RC Cell-based Kakuhou later replace earlier Kagune positions and allow manifestations to be shaped by Simu’s will. 45
• Can combine Koukaku, Weihe, Rinkaku, and Ukaku into Kakuja mode for close combat. 90
• Has incorporated Ibuse’s poison glands into clone bodies and Kagune tentacles, enabling the release of corrosive poisonous gas. 127

Clones and Distributed Bodies

Simu can split his operations among multiple bodies while keeping his true Blood Pool hidden underground. 57

• Blood Pool Clone — A clone based on Simu’s main-body genes that closely resembles him and can reproduce his abilities. 57
• Crow Clone — A raven-derived clone carrying part of Simu’s spiritual power, commonly used under the identity Mr. Crow. 57
• Human Clone — A humanoid Kagune-based body suitable for ordinary interaction, combat, and genetic modification. 3 97
• Ninja Clone — An all-attribute combat body engineered for ninjutsu, sealing, Space-Time Ninjutsu, and chakra control. 97
• The functions of Crow, Human, and Ninja Clones can be combined to create specialized hybrid bodies. 97
• Uses clones as remote laboratories, battlefield bodies, decoys, infiltrators, and vessels for rare bloodline abilities. 73 208 286

Reconnaissance and Swarm Control

Simu controls specially created Ravens and Black Beetles as extensions of his senses and will. 13

• Ravens share vision with Simu and serve as long-range scouts or mass distractions. 13
• Black Beetles possess sensory ability, devour prey, transport corpses, store energy, and can be mass-produced. 13 37 49
• He covertly replaced the crows around Jashin Cult headquarters and spread beetles through rooms, trees, and soil, effectively monitoring the area. 13 38
• Uses Ravens and beetles to survey a twenty-kilometer area after Orochimaru’s clone is defeated. 43
• His chakra-less beetles can infiltrate guarded locations without attracting conventional chakra detection, including Root and major Konoha clans. 173 183
• Some insects possess infrared vision, thermal vision, scent detection, and other specialized senses, providing Simu with multi-angle battlefield perception. 235
• Establishes regional Blood Pool and Broodmother relays to expand surveillance and maintain long-distance chakra supply. 115 286
• Developed Beacon Bugs that can use a summoned creature’s return formation to identify the coordinates of otherwise hidden locations, including Mount Myōboku. 332

Genetic and Chakra Research

Simu develops his abilities through direct genetic analysis and experimentation rather than conventional training. 45 46

• Analyzes ninja genes for Fire, Water, Lightning, Earth, and Wind Release. 45
• Determines that elemental chakra affinities depend on specific genetic segments that can be cultivated, activated, and transplanted. 46
• Modifies Hidan to refine all five elemental chakra types and use Simu’s ninjutsu. 46
• Discovers RC Cells, mutations in which Kagune become integrated into a host’s body under extreme emotional stimulation. 45
• Identifies Kekkei Genkai as specialized genetic fragments that generate substances capable of fusing chakra natures into a new type of chakra. 157
• Replicates Magnet Release through genetic modification and uses the result as a foundation for studying Wood Release and other bloodlines. 157 159
• Studies Hashirama Cells, Uchiha genes, Hyuga genes, Kaguya genes, Tailed Beast Chakra, Sage-related biology, and the Demonic Statue of the Outer Path. 159 247 275 292 315
• Recognizes that Hashirama’s Cells contain an unresolved component responsible for Wood Release’s exceptional power; his analysis stalls at approximately eighty-five percent. 183 286

Ninjutsu and Chakra Mastery

Simu’s Ninja Clones possess all five elemental chakra natures, Yin Release, Yang Release, sealing talent, and Space-Time Ninjutsu potential. His comprehensive understanding of chakra pathways allows him to perform many techniques with little or no need for hand seals. 97

• Uses advanced Water Release techniques such as Water Wall and Water Dragon Bullet with minimal hand seals. 97
• Combines Wind Release: Pressure Damage and Lightning Release: False Darkness into the self-performed composite technique Roar of the Wind and Thunder God. 127
• Employs Sound Cry Technique and Demonic Sound Lock Technique to incapacitate targets and place them under sound-based genjutsu. 60
• Intends to develop sound-based genjutsu into a passive, speech-triggered method of influencing enemies. 60
• Has copied and begun adapting Konoha’s forbidden techniques and clan techniques, including Shadow Jutsu, Expansion Jutsu, Mind Ninjutsu, Insect Manipulation, and Gentle Fist. 247
• Combines techniques from the Book of Seals into Heaven and Earth, a personal Space-Time Ninjutsu that allows him to travel to locations containing his chakra. 332

Wood Release

Through Hashirama Cell research and engineered Wood Release bodies, Simu becomes an exceptionally capable Wood Release user. 159 167

• Learns Wood Release: Violent Spear Tree and Four Pillars House Technique almost immediately after reading their scrolls. 169
• Masters Deep Forest Emergence, generating a massive controllable forest and reclaiming its chakra afterward. 182
• Can use Wood Dragon Technique to restrain targets and absorb their chakra. 183 286
• Can create a colossal Wood Human Technique construct for large-scale combat, defense, and direct attacks against Tailed Beasts. 183 286
• Uses Deep Forest Emergence’s sleep-inducing pollen to incapacitate Yagura. 287
• His Wood Release remains inferior to Hashirama’s original power, but is sufficient to suppress Tailed Beasts, disrupt Tailed Beast Bombs, and sustain prolonged battlefield control. 286 287

Dōjutsu, Genjutsu, and Susanoo

Simu uses engineered Uchiha bloodlines and transplanted dōjutsu rather than possessing an innate Uchiha heritage. 208 226

• Creates Uchiha clones able to house Shisui’s and Fugaku’s Mangekyō Sharingan. 208 292
• Uses ordinary Sharingan for genjutsu, dynamic vision, ninjutsu copying, and stealthier operations. 226 315
• Uses Mangekyō Sharingan to impose powerful genjutsu, control targets such as Fuguki Suikazan, and enter spiritual worlds. 274 304
• Can disrupt his own chakra circulation to break conventional genjutsu after being trapped. 215
• Uses Mangekyō Sharingan-derived Susanoo, progressing from earlier manifestations to armored third-stage and fourth-stage Black Tengu Armor forms. 304 314 326
• Uses Fugaku’s Mangekyō ability, Narukami/Thunder God Sword, to summon lightning through Susanoo. 314
• Understands the Eternal Mangekyō Sharingan’s requirement of merging the Mangekyō of two brothers, though he has not successfully created one. 292

Yin-Yang Release, Sealing, and Soul Manipulation

Simu’s increasing spiritual power supports extensive research into Yin Release, Yang Release, sealing, souls, and Living Corpse Reincarnation. 57 73 94

• Uses Yin-Yang Sealing Techniques to divide Tailed Beast chakra and souls without simply destroying the original Jinchūriki. 287
• Creates newly independent Tailed Beast wills through Yin-Yang Release, forming a creator-and-summon relationship distinct from conventional mind control. 287
• Can enter spiritual worlds through the Soul Transformation Technique and interact directly with the Nine-Tails, Minato’s chakra imprint, and Indra. 208 304 316
• Possesses significant resistance to spiritual attacks and genjutsu due to his enhanced mental power and distributed nature. 39 215
• Continues researching Living Corpse Reincarnation, but initially reaches only 26.4% analysis and cannot yet obtain true body-transfer immortality through the technique. 57

Tailed Beast Chakra and Summoning

Simu treats Tailed Beasts and their chakra as both weapons and biological research materials. 151 286

• Tailed Beast Shell — A parasite developed from Shukaku’s chakra that grants hosts a Tailed Beast Chakra cloak; Hidan becomes its first major test subject. 151
• Uses seals and Yin-Yang Release to split portions of the Three-Tails and Six-Tails, creating Little Isobu and Little Saiken as loyal summoned creatures. 287
• Commands Matatabi in battle and equips it with Susanoo armor. 314
• Captures the Seven-Tails and obtains Hero’s Water from Takigakure, bringing his collection of Tailed Beast resources closer to the requirements for a Ten-Tails project. 314
• Studies the Demonic Statue of the Outer Path, its shell, and its invasive vitality-absorbing fungus while building a Ten-Tails prototype. 73 315

Engineered Creatures

• Raven — Vision-sharing reconnaissance organism. 13
• Black Beetle — Energy-storing scout, corpse transporter, and combat swarm organism. 13 49
• Explosive Bug — A living explosive containing the formula for a Kibaku Fuda; Simu uses them to melt through a steel gate with “Bug Release: Great Character Explosion Technique.” 49
• Evil-Faced Ghost Snake — A composite creature made from ninja, Kagune, and snake genes; it possesses armor, Ukaku deployment, an Evil Ghost Mask, and the Heart of the Five Elements. 46
• Three-Headed Evil-Faced Ghost Snake — An upgraded version able to cast different ninjutsu from each head and combine them into composite attacks. 151
• Harpy — A flying Jashin Race derived from bird genes and specialized ninjutsu; Xianai’s Harpy body possesses sound-based genjutsu, poison gas, and disease-spreading potential. 75 151
• Apostle of Desire — A colossal flesh-based organism whose combat power can rival a Tailed Beast and whose self-destruction can approach Tailed Beast Bomb-level force. 73 89
• Apostle of Fear — A powerful Apostle sealed into Shiraishi Mori, making him a Jinchūriki-like host. 92
• Blood-Pouch Worm — A vitality- and Yang Release Chakra-storing organism that functions as portable medical support. 73
• Blood-Spirit Worm — A smaller, more advanced Blood-Pouch Worm that heals severe injuries, stores Yang Release Chakra, absorbs limited Natural Energy, and temporarily enhances physical ability at the cost of possible berserk behavior and exhaustion. 94
• Desert Dragonfly — A rapidly reproducing desert reconnaissance species that can also carry Explosive Bugs for bombing attacks. 115 151
• Ghost-Faced Wind Scorpion — A swarm predator that uses fear-inducing pheromones and serves as a primary desert combat organism. 115 151
• Poison-Blade Centipede — A venomous subterranean ambush organism designed for assassination and sabotage. 115 151
• Desert Doghead — An intelligent battlefield commander created to coordinate Simu’s desert biological forces. 151
• Eagle Eye — A Byakugan-derived species with exceptional vision and sensory perception. 247
• Beacon Bug — A parasitic tracking organism used to acquire the spatial coordinates of hidden summoning realms. 332

Relationships

• Lord Jashin — Patron and source of Simu’s Immortal Body. Simu professes the goal of offering the entire Shinobi World to Jashin, though he also exploits Jashin’s power to fuel his own creations and repeatedly drains Jashin-related energy reserves for production. 1 13 46 151
• Hidan — Fellow God Child, rival, experimental subject, and recurring target of Simu’s decapitations. Simu dominates their relationship, but Hidan is fiercely attached to him and attacks the Cult Leader after believing Simu has been killed. Hidan later becomes the first major Tailed Beast Shell test subject. 3 7 39 40 151
• Jashin Cult Leader — Nominal superior who accepts Simu as a God Child, then attempts to seize his powers through Living Corpse Reincarnation. Simu knowingly allows the possession attempt to study the technique. 3 38 39
• Shiraishi Mori — A Ghoul whose emotional mutation into RC Cells becomes Simu’s most valuable research result. Simu recognizes Mori’s courage but treats his suffering and transformation as experimental data. He later seals the Apostle of Fear into Mori, turning him into a Jinchūriki-like experimental host. 34 35 45 92
• Chairman Sakamoto — Businessman and Ghoul client whom Simu supplies with Kagune. Simu later defeats him effortlessly and recovers his remains for research. 23 24 34 37
• Orochimaru — Enemy, scientific rival, and eventual transactional partner. Orochimaru initially seeks Simu as a test subject, while Simu studies Orochimaru’s Snake Clone, Wind Release, snake genes, and body-transfer technique. They later cooperate on Hashirama Cell research, Wood Release bodies, and Simu’s entry into Konoha. 42 43 45 159
• Kikuchi Miura — Jashin Cult ninja whose precise Water Release techniques introduce Simu to practical ninja combat. Miura’s genes later contribute to Simu’s Water Release research. 18 37
• Uzumaki Rii — Former Orochimaru test subject rescued by Simu. Her exceptional Uzumaki vitality and natural-energy resistance make her both a valued follower and research subject; she becomes intensely devoted to Simu and addresses him as Master. 51 53 74 158
• Jugo — A naturally gifted Natural Energy vessel whom Simu studies, recruits, and stabilizes through a spiritual imprint. Jugo is comparatively compassionate and often disturbed by Simu’s methods, but remains an obedient subordinate and representative. 60 62 75 158
• Xianai — Former Orochimaru subordinate remade as a Harpy. She transfers her obsession with Orochimaru into fanatical loyalty toward Simu and competes with Rii for his attention. 74 75 158
• Nagato — Akatsuki collaborator and mutual exploiter. Nagato provides Simu with Yin Release techniques, Demonic Statue material, intelligence, and access to Tailed Beast operations, while Simu offers biological weapons, war planning, and assistance in capturing Tailed Beasts. 70 72 73
• Konan — Nagato’s wary partner, who consistently suspects that Akatsuki is empowering an eventual enemy by supplying Simu with resources. 70 73
• Sasori — Research collaborator and fellow artificial-life enthusiast. Simu values Sasori’s Human Puppet Technique and intellect, encourages his bodily evolution, and works with him on sealing, Yin-Yang Release, and Tailed Beast operations. 133 137 151 286
• Danzō Shimura — Simu’s nominal Root superior under the identity B. Danzō attempts to indoctrinate, train, and eventually control Simu as a Wood Release weapon, while Simu feigns obedience and uses Root to acquire techniques, intelligence, and resources. 165 174 182 183
• Gaara — A young Shukaku Jinchūriki whom Simu treats with unexpected warmth. Simu later uses Gaara-derived bodies in research and assigns Jugo to train him. 111 159
• Itachi Uchiha — A powerful Uchiha opponent and unwilling subject of Simu’s fascination with the Sharingan. Simu provokes him through Sasuke, admits to killing Shisui, and tests Wood Release and Mangekyō powers against him. 214 215
• Sasuke Uchiha — A Uchiha survivor whose body and soul become central to Simu’s research. Simu investigates the chakra sustaining Sasuke, encounters Indra in his spiritual world, and promises to revive Sasuke as part of his arrangement with Indra. 235 304 316
• Indra Ōtsutsuki — The Uchiha ancestor residing through Sasuke’s reincarnation cycle. Initially hostile to Simu’s use of stolen Uchiha power, Indra later enters a reluctant alliance with him in exchange for Sasuke’s revival and information on Asura’s reincarnation. 304 316
• Nine-Tails — A hostile but useful potential ally. Simu enters Naruto’s mental world, openly proposes releasing the Nine-Tails to destroy Konoha, and later battles Minato’s chakra imprint while pursuing control over the seal. 208 226 227
• Minato Namikaze — A chakra imprint within Naruto who opposes Simu’s attempt to remove the Nine-Tails’ seal. Simu defeats the remnant in Naruto’s spiritual world but acknowledges Minato’s legendary skill. 226 227
• Kakuzu — Former enemy recruited after recognizing Simu’s overwhelming superiority. Simu assigns him to lead Gaara, Haku, and Kimimaro on missions for the Jashin Cult. 304
• Kimimaro — A Kaguya Clan survivor whose Shikotsumyaku and severe genetic burden intrigue Simu. Simu provides him with replacement bodies that can mitigate the bloodline’s physical side effects. 274 275 284
• Matatabi, Little Saiken, and Little Isobu — Tailed Beasts or Tailed Beast derivatives under Simu’s command. Little Saiken and Little Isobu regard him as their creator, while Matatabi serves him willingly in combat. 287 314
