Personality =
Originally a human police officer with a strong sense of duty, Hoshikuzu's personality was warped by the [System] and his survival in Enkanomiya. He is biologically driven by Gluttony, viewing enemies as "calories" and problems as "snacks." However, thanks to Alice's influence and the skill [n% I = W], he retains a core of humanity. He is fiercely protective of his "hoard" (his family), brutally efficient against threats, and prone to dry, terrifying humor. He denies being a father figure despite adopting half the continent's traumatized children.

Titles & Skills:
Before Transcending
- n% I = W: A unique skill possessed by Hoshikuzu as a reincarnated soul. It anchors his original human consciousness (Andrews Ragnvaldr) to his current Dragon body, preventing his ego from collapsing under the weight of his rapid evolution and Abyssal consumption. It grants Hoshikuzu a restoration of HP, MP, and SP upon leveling up, though at his current God-tier status, the System struggles to fill his massive reserves completely.
- Stats: Hoshikuzu's stats varried greatly throughout his time in Enkanomiya. Initially, he was so weak that any directly attack against his opponents were utterly ineffective, forcing him to rely on ambushes and setting traps. The only thing of note was his speed, which was boosted by Skanda. As he evolved, though, his stats naturally increased. Particularly, he began to focus on developing his magic after acquiring Height of Occultism. However, his biggest increase came when he was named by the Legendary Mage Alice / Klee's Mother, giving his strength on-par with a legendary-class monster. After evolving into an Dragon Sovereign, Hoshikuzu possesses the second highest stats within the System, surpassed only by The Heavenly Principles.
* HP Ultra-Fast Recovery (Previously HP Auto-Recovery and HP Rapid Recovery): Allows Hoshikuzu to regenerate lost tissue almost instantaneously. Unless an attack destroys his entire body or soul in a single microsecond, Hoshikuzu can regrow limbs, organs, and even his head within moments, burning his massive SP reserves to fuel the regeneration.
* SP Rapid Recovery (Previously SP Recovery Speed and SP Rapid Recovery): A passive skill that allows Hoshikuzu to recover Stamina (SP) at a terrifying rate. He can fight for months without rest. Even after unleashing a continent-level attack, Hoshikuzu returns to full fighting fitness within minutes.
* SP Minimized Consumption (Previously SP Lessened Consumption and SP Minimized Consumption): drastically reduces the energy cost of Hoshikuzu's physical actions. Moving at the speed of light or crushing a mountain barely registers as "effort" for him, allowing him to maintain his True Dragon God form indefinitely.
* Height of Occultism (Previously MP Recovery Speed, MP Rapid Recovery, MP Lessened Consumption and MP Minimized Consumption): The pinnacle of magic management. It grants Hoshikuzu infinite MP regeneration within the System's logic. It allows him to cast any spell without needing the specific skill (by manually constructing the formula) and lets Hoshikuzu overcharge spells with excess mana, turning a simple fireball into a nuclear event.
* Fortitude (Previously Strength and Herculean Strength): Increases Hoshikuzu's physical defense and HP capacity to divine levels. It ensures that his biological vessel is tough enough to contain the volatile energies of the seven Authorities he has consumed.
* Stronghold (Previously Solidity and Sturdy): Enhances Hoshikuzu's physical durability and density. It makes his body heavy and immovable, allowing Hoshikuzu to withstand impacts that would shatter an island without being knocked back.
* Skanda (Previously Running and Acceleration): Hoshikuzu's specific Reincarnation Bonus. It grants him a multiplier to his Speed stat and its growth rate. This allows Hoshikuzu, a massive Dragon God, to move with the agility of a speedster, often disappearing from the vision of Archons during combat.
* Ultimate Life (Previously Life and Longevity): The final evolution of health stats. It grants Hoshikuzu biological immortality (agelessness) and huge bonuses to all resistance checks. It signifies that Hoshikuzu has transcended the natural life cycle of Teyvat.
* Fortune (Previously Persistent and Endurance): Allows Hoshikuzu to survive lethal odds through sheer luck and probability manipulation. It also ensures that enemies are more likely to miss their attacks against him or suffer critical failures.
* Ultimate Movement (Previously Instantaneous and Instant Body): Allows Hoshikuzu to teleport short distances instantly by folding space, effectively giving him zero-frame movement. He can blink behind an enemy, strike, and return to his original position before the sound of the movement catches up.
- Attacks:
* Heretic Attack: An attack imbued with the power to rot the soul. Hoshikuzu infuses his physical strikes (claws, tail, bites) with this energy, causing damage directly to the opponent's soul and MP, bypassing physical defenses entirely.
* Bolt Attack (Previously Lightning Attack): Hoshikuzu coats his body in the condensed Electro Authority. His physical strikes land with the force of a lightning bolt, paralyzing enemies and piercing through magical barriers.
* Flood Attack (Previously Water Attack): Hoshikuzu wreathes his limbs in the pressure of the Primordial Sea. His strikes carry the crushing weight of the ocean and can dissolve non-godly entities on contact.
* Freeze Attack (Previously Ice Attack): Hoshikuzu applies the concept of "Entropy" to his attacks. A scratch from him can freeze the blood in an opponent's veins instantly, halting their molecular motion.
* Energy Super-Attack (Previously Energy Attack): A raw projection of Hoshikuzu's Stardust Mana. He can fire beams of pure energy from his mouth or hands that disintegrate matter on a sub-atomic level.
- Enhancement:
* Destruction Super-Enhancement (Previously Destruction Enhancement): Maximizes the physical damage Hoshikuzu deals to objects and structures. A single punch can shatter Divine Constructs or level a city.
* Cutting Super-Enhancment (Previously Cutting Enhancement): Sharpens Hoshikuzu's claws and magic blades to the point where they can sever the fabric of space itself.
* Impact Super-Enhancement (Previously Impact Enhancement): Increases the shockwave generated by Hoshikuzu's blows, allowing him to damage enemies behind the primary target.
* Piercing Super-Enhancement (Previously Piercing Enhancement): Allows Hoshikuzu's attacks to ignore a significant portion of an enemy's armor or defensive stats.
* Shock/Bolt/Flood/Freeze/Fire Enhancement: These skills exponentially increase the damage Hoshikuzu deals when using the respective elemental authorities (Electro, Hydro, Cryo, Pyro), ensuring his elemental magic hits harder than the Archons who originally held them.
- Active:
* Battle Divinity (Previously Mental Warfare): A mental aura that forces Hoshikuzu's dominance onto the battlefield. It instills hesitation in enemies while granting Hoshikuzu absolute calm and tactical clarity during combat.
* Magic Power Conferment: Allows Hoshikuzu to transfer his vast MP to others. He uses this to jumpstart artifacts (like the Holy Lyre) or recharge his allies (like Neuvillette or Raiden Ei).
* Divine Dragon Power (Previously Wyrm Power and Dragon Power): Hoshikuzu's signature aura. It releases a crushing gravity field that can flatten lesser beings instantly. It asserts his status as a being superior to normal biological life.
* Divine Dragon Barrier (Previously Wyrm Barrier and Dragon Barrier): A multi-layered forcefield generated by Hoshikuzu's Void energy. It automatically deploys to block attacks that would harm him, capable of withstanding the Heavenly Principles' cubes.
* Undying King (Previously Undying Body and Undying Commander): The ultimate survival skill. If Hoshikuzu's HP hits 0, this skill forces it to remain at 1 as long as he has MP remaining. It makes him functionally unkillable as long as he has energy to burn.
* Energy Conferment: Similar to Magic Power Conferment, but Hoshikuzu can grant SP (Stamina) to allies, effectively healing their fatigue instantly.
* Psychokinesis (Previously Telekinesis): Allows Hoshikuzu to manipulate matter with his mind. At his level, he can rip islands out of the ocean or hold a collapsing ruin together with a thought.
* Panoptic Vision (Previously Telescopic Sight and Clairvoyance): Allows Hoshikuzu to expand his viewpoint to a "God's Eye" perspective. He can view any location he has previously visited or currently occupies from multiple angles simultaneously.
* Magic Divinity (Previously Magic Warfare): The absolute mastery of spellcasting. Hoshikuzu can alter the properties of magic mid-cast, combine elements that shouldn't mix, and cancel out enemy spells by disrupting their formulas.
* Iron Defense: An active hardening of Hoshikuzu's skin. It turns his flesh into a substance harder than any metal in Teyvat, capable of shattering weapons that strike him.
* Naming: A ruler's privilege. Hoshikuzu can grant a "True Name" to a subordinate, evolving them into a higher species and creating a soul corridor between them.
* Dimensional Maneuvering (Previously Spatial Maneuvering): Allows Hoshikuzu to walk on air or "double jump" by creating solid platforms of space. He can stand upside down on the sky or walk vertically up walls.
* Medicine Synthesis: Obtained from studying Baizhu. Hoshikuzu can synthesize potions, poisons, and elixirs inside his own body or using raw materials, creating cures for divine curses.
- Passive:
* Tyrant (Previously Intimidation): A constant, low-level aura of intimidation. Weak-willed beings instinctively fear and obey Hoshikuzu, preventing random mobs from attacking him.
* Night Vision: Hoshikuzu can see perfectly in absolute darkness.
* Evasion: Increases the probability of Hoshikuzu automatically dodging an attack without conscious thought.
* Perception Expansion (Previously Auditory Expansion and Vision Expansion): Extends Hoshikuzu's hearing and sight range to cover entire nations.
* Shieldsmanship: Mastery over defensive barriers. Hoshikuzu knows the optimal angle to deflect attacks to minimize damage to his barriers.
* Presence Perception: Allows Hoshikuzu to sense invisible or hidden enemies within a massive radius.
* High-Speed Flight (Previously Flight): Allows Hoshikuzu to fly at supersonic speeds without being hindered by air resistance.
* Martial Arts (Previously Athletics): Grants Hoshikuzu mastery over unarmed combat, allowing him to utilize his immense strength with technique rather than just brute force.
* Divine Scales (Previously Dragon Scales and Imperial Scales): Hoshikuzu's skin reflects hostile magic and physical attacks. Low-tier attacks bounce off him and hit the attacker instead.
* Concealment (Previously Camouflage): Allows Hoshikuzu to hide his "True Dragon God" status, appearing as a normal human to standard appraisal spells.
- Leadership:
* Tactician (Previously Leadership and Command): Enhances the coordination and stats of Hoshikuzu's allies when he commands them.
* Fartalk (Previously Telepathy): Telepathy. Hoshikuzu can speak into the minds of anyone he has a connection with, regardless of distance.
* Cooperation: Allows Hoshikuzu to share his Mana or senses with his allies seamlessly during battle.
* Kin Control: Grants Hoshikuzu absolute command over lesser draconic beings (Vishaps). He can order the armies of the Night Kingdom or Enkanomiya to do his bidding.
- Perception:
* Thought Super-Acceleration (Previously Thought Acceleration): Hoshikuzu perceives the world in slow motion. He can formulate complex battle plans in the split second before an attack lands.
* Appraisal: The ultimate information tool. Hoshikuzu can read the stats, history, weaknesses, and hidden lore of any target or object.
* Danger Perception: A sixth sense that alerts Hoshikuzu to incoming threats or killing intent before the attack is launched.
* Parallel Minds (Previously Parallel Thinking): Splits Hoshikuzu's consciousness into multiple independent threads (up to 10). This allows him to fight, cast magic, analyze data, and have a conversation simultaneously.
* Future Sight (Previously Prediction and Foresight): Allows Hoshikuzu to see a few seconds into the immediate future, predicting enemy moves with 100% accuracy.
* Record (Previously Memory): Hoshikuzu can "Save" the state of reality. He archives the souls and memories of people (like Raiden Makoto or Focalors) to prevent them from being erased by Irminsul or death.
* Space Perception: Grants Hoshikuzu a 3D grid-map of his surroundings, allowing him to sense spatial distortions or hidden dimensions.
* Technique Perception: Allows Hoshikuzu to instantly understand and copy physical techniques or spell structures just by seeing them once.
- Magic:
* Heretic Magic: Soul-destroying magic. Hoshikuzu learned this early on in Enkanomiya. It allows him to damage the soul directly or create realistic illusions to torment enemies.
* Tide Magic (Previously Flood Magic and Water Magic): Hydro Authority. Hoshikuzu can summon tsunamis, control blood, or dissolve matter into water.
* Abyss Magic: Void Authority. Hoshikuzu can summon the corrosion of the Abyss, corrupting matter and erasing light.
* Dimensional Magic (Previously Spatial Magic): Copied from Raiden Ei (Musou no Hitotachi logic). Hoshikuzu can slice through the fabric of space to open portals, teleport, or cut distant targets instantly.
* Freeze Magic (Previously Ice Magic): Copied from Ganyu and the Tsaritsa. Hoshikuzu can lower the temperature to absolute zero, freezing time and space in a localized area.
* Tempest Magic (Previously Gale Magic and Wind Magic): Copied from Dvalin. Hoshikuzu can create hurricanes, control the weather, and fly effortlessly.
* Bolt Magic (Previously Lightning Magic): Copied from Raiden Ei. Hoshikuzu wields the highest form of Electro, capable of vaporizing matter and moving at lightning speed.
* Fire Magic: Copied from Mavuika. Hoshikuzu wields the flames of resurrection and destruction, capable of burning even in a vacuum.
- Resistance / Nullification:
* Deadly Poison / Rot / Faint / Fear / Pain / Impact / Destruction / Heat / Black / Heresy / Cutting / Exhaustion / Piercing / Suffering / Status Condition / Freeze / Shock: Hoshikuzu has reached Nullification or Super-Resistance in all these categories. This means he is immune to biological needs (sleep/eating), immune to mental manipulation, immune to the corruption of the Abyss (Heresy/Black), and impervious to elemental extremes (Heat/Freeze). He essentially ignores the laws of physics that would harm a biological entity.
- Ruler:
* Charity: Grants the [Miracle Magic] skill. Hoshikuzu can heal injuries that are conceptually impossible to heal (like Erosion or Soul Damage). It gives the effect of ultra-fast regeneration to anyone he recognizes as an ally within his range.
* Lust: Grants the [Jinx Magic] skill. It allows Hoshikuzu to brainwash or charm targets. In his case, it manifests as an irresistible charisma that draws powerful women to him and allows him to curse enemies with bad luck.
* Chastity: Grants the [Physical Super-Resistance] skill. Hoshikuzu can expand his divinity to create an inviolable field—a "Safe Zone" where no attack can enter and no unauthorized entity can exist. It is the ultimate defense for his home and family.
- Humanification: Allows Hoshikuzu to compress his massive biological mass and infinite energy into a compact, human form (resembling his original self, Andrews). While in this state, his density is incredibly high, making him immovable to normal forces. This skill is essential for interacting with civilized society, entering buildings, and being intimate with his wives without his "True Dragon God" gravitational pull destroying the room. However, due to his overflowing power, dragon traits (such as slit eyes, scales, or stardust wings) will manifest involuntarily if he loses emotional control or takes serious damage.
After Transcending
Conjuring: Having transcended the System like a God, Hoshikuzu is still able to use any of those former skills. However, he learned through the System to create his own skills either by merging his former skills or conjuring new ones and can activate them from anywhere on his body.
- Physical Strength: By manually enhancing his body with MA Energy (World Energy), Hoshikuzu's physical capabilities are able to surpass the System's limit. He can reinforce his muscles to lift tectonic plates or strike with enough force to shatter the false sky, purely through biological enhancement.
- Administrator Authority: As the name implies, this is the unique ability that the Administrators of the System possess, allowing them to freely manipulate the System, make changes to it, or even add new features should they desire. One of the abilities that the Authority of an Administrator possesses is the ability to create and access a crystal ball-like object that grants the Administrator the ability to see events in real time anywhere in the world within the System's bounds.
* Message Logs: While Hoshikuzu no longer receives automated messages from the System, he can directly search and review its logs. This grants him access to the Irminsul Server, allowing him to read the history of Teyvat, the truth of the Descenders, and the deleted records of "forgotten" entities.
* Message Sending: Hoshikuzu can send messages to others that directly appear inside their minds. He can broadcast to a single person or the entire population of Teyvat simultaneously. This bypasses all mental defenses, as it functions as a "System Notification."
* Removing Visions: As an Administrator, Hoshikuzu can revoke the elemental authority granted to humans. He can simply "delete" a Vision from existence or sever the connection between the Vision holder and Celestia/The Archon, rendering the gem inert.
* Resurrection: Only within the System is Hoshikuzu able to resurrect the dead. By accessing the System's backup data (Leylines), he can reconstruct a person's body and pull their soul back before it fully dissipates into the Leyline flow, effectively reviving them with their memories intact.
* Soul Shelter: Hoshikuzu can protect souls from the natural cycle of erosion or recycling. He can store souls within his own Stardust or in a designated pocket dimension (like the Ragnvaldr Estate), preserving them indefinitely until he chooses to grant them a new body.
- Skill Creation: Phanes created Gluttony on a whim after listening to Hoshikuzu's short rant. Phanes himself has implied that the skills that he gave to Hoshikuzu was personally created by him based on how he saw him, thus implying that an Administrator could easily conjure and create new skills and give them to whoever they please within the bounds of the System.
* Physical Nullification: Integrates Destruction, Impact, Cutting, Piercing, and Shock Resistance. Hoshikuzu surrounds his body with a permanent, imperceptible field of distorted space and hardened energy. Physical attacks simply lose their kinetic energy upon contact, failing to scratch him unless they possess "God-Slaying" properties.
* Status Condition Nullification: Integrates Poison, Paralysis, Petrification, and Exhaustion Resistances. Hoshikuzu has total control over his biological state. He can instantly isolate and neutralize any foreign toxin or curse entering his body, decomposing it into harmless energy. He no longer needs sleep or food for survival.
* Spacetime Domination: Giving the user complete control over the element of space and even the ability to affect time.
** Dimensional Travel: Hoshikuzu can breach the "Walls of the World." He can travel between the Bubble Universe of Teyvat and other realities (such as the Honkai Universe or Earth), allowing him to collect his multiverse harem.
** Pocket Dimensions: Hoshikuzu creates and maintains independent sub-spaces, most notably the Ragnvaldr Estate. These dimensions operate on his own laws of physics, allowing him to store infinite items or house living beings in a paradise of his design.
** Teleportation: Instantaneous movement without coordinates. He simply "edits" his location from Point A to Point B. There is no travel time, and no barrier can block him.
* Immortality: Hoshikuzu's existence is no longer tied to a physical heart or brain. He is a construct of energy and soul. Even if his body is vaporized, he can reconstruct it from the Void instantly. He will exist as long as he has energy, and since he produces his own energy via Gluttony, he is effectively eternal.
* Gravity Manipulation: It enables the user to manipulate and utilize gravity. Hoshikuzu can crush enemies by increasing gravity by 1000x in a localized area, create black holes to absorb attacks, or invert gravity to make continents float. This power stems from his nature as a "Star."
* Universal Perception: Universal Perception allows for the perception of nearly all things within an extremely wide radius. It is an enhanced version of Presence Perception with superior sensory capabilities. The user can perceive not only light and sound — inherited from Presence Perception — but also killing intent, heat, magic flow, soul wavelengths, and dimensional disturbances within an extremely large range (Planetary scale).
* Nihility Magic: It's a forbidden technique of Abyss Magic that makes use of Summoning magic to call forth the Nihility from the Abyss of Hell. It does not "damage" the target; it erases them. Whatever this magic touches is returned to nothingness, bypassing regeneration and durability.
* Enhanced Body Double: It allows the user to create a more durable version of Body Double. It is sufficient enough in quality to potentially be used as an incarnation medium for True Dragons. Hoshikuzu can create autonomous clones to manage the Ragnvaldr Estate or protect his children. These clones possess a fraction of his power but are indistinguishable from the real him to anyone but another Administrator.
- Multidimensionnal Barrier: Hoshikuzu can create magical and physical barriers around himself and others. These barriers exist in multiple dimensions simultaneously, meaning an attack must hit him in the physical realm, the spiritual realm, and the spatial realm at the exact same time to bypass his defense.
- Transformation: Hoshikuzu can freely switch between a human and his True Dragon God form with just a thought.
- Bloodline Overwrite: Hoshikuzu possesses the ability to rewrite the genetic code and spiritual composition of other beings by infusing them with his own True Dragon God blood or concentrated Stardust Mana.
* Biological Reformatting: He can transform humans, spirits, artificial beings (like puppets), or even hilichurls into biological members of the Ragnvaldr lineage. He can designate the biological relationship upon infusion (Sister, Brother, Daughter, Son).
* Traits Granted: Those who undergo this process gain traits of a True Dragon, such as [Ultimate Life] (Immortality/Longevity), immense mana capacity, physical resilience, and potential physical mutations like horns or void-eyes.
* Soul Binding: This process permanently links their soul to Hoshikuzu's "Kin Network," ensuring they share his protections (such as [Status Condition Nullification]) and cannot be erased by Irminsul or Erosion.
** Example: This is how he "adopted" Scaramouche (turning a puppet into a biological dragon-kin son) and how he ensures his human wives (like Furina) can live eternally alongside him.
