History

Yang Yunzhi is a transmigrator whose memories awakened at age three after reincarnating in the Flower Country. In his previous life, he was an ordinary freelancer who made videos, streamed, delivered food, and eventually wrote novels. In the One Piece world, he used his knowledge to modestly improve his family’s finances and completed his education at Golden City Maritime Academy. His attempts to become strong through physical training, Sea King meat, and swordsmanship all failed; a dojo master judged his talent average. 1

On his eighteenth birthday, Yang received and immediately ate a transformed pineapple that proved to be the Paramecia Color-Color Fruit. The act activated the Justice System, which made organizational promotion the foundation of his growth. After deciding that the Marines offered the most useful advancement structure, he investigated West Blue bases, selected Hina’s Base 36, fled his family home, and enlisted under the false name “Rick.” 1 2 3 4

Yang failed Hina’s physical entrance examination but used his literacy and education to secure a clerical role. He deliberately refused Hina’s offer of a second-lieutenant rank, choosing to begin as a third-class private so he could receive system rewards from every promotion. As Base 36’s clerk and later adjutant, he reformed recruitment, discipline, logistics, literacy education, military law, intelligence gathering, and combat planning. 5 6 21 23 25

His discussions with Hina transformed their relationship from commander and subordinate into ideological partners. Yang argued that piracy is driven by poverty, oppression, and noble exploitation rather than Roger alone, and that the Marines must eventually resist improper World Government control. Hina’s conviction during one such debate culminated in her awakening Conqueror’s Haki. 11 17

After acquiring the Door-Door Fruit, Yang began building an independent intelligence network alongside his Marine career. He recruited Bezos on Ghost Mulberry Island, tracked down Nico Robin, brought the Celo Five into his organization, and used Little Bean’s Link-Link Fruit network to establish secure communications, local informants, and DD Meetings. 29 33 37 41 43

Yang’s intelligence work enabled Base 36 to annihilate the Blood Knife Pirates through a covert, coordinated assault designed to minimize Marine casualties. Following the victory, he was promoted to Captain and began considering a wider strategy involving hospitals, public welfare, intelligence networks, and Hell’s Curse soul accumulation. 45 46 49 50

Appearance

Yang initially appeared physically slight but conventionally handsome by the standards of the One Piece world. His repeated system promotions enhanced his physique, health, and appearance, giving him firmer muscles, sharper features, and an increasingly refined presence. 5 26

• Retains black-and-white eyes despite possessing the Byakugan; the system fused the bloodline with his original eyes rather than changing them white. 14
• Often presents himself publicly as a literate clerk, strategist, or civilian officer rather than revealing his combat strength. 22 49
• Uses ordinary clothing and disguises while conducting intelligence work outside Marine territory. 43
• Wears Zephyr, a green jade feather pendant, concealed beneath his collar. 49

Personality

Yang is pragmatic, analytical, and intensely ambitious. He evaluates institutions, superiors, Devil Fruits, military positions, and potential allies according to their long-term strategic value. His decision to join Hina’s base, begin at the lowest Marine rank, reject a Headquarters transfer, and remain in the Four Seas all reflect his preference for controllable influence over immediate prestige. 3 5 29 30

His concept of justice is personal rather than institutional. He rejects pirates, distrusts the Marines’ obedience to the Celestial Dragons, and considers the Revolutionary Army politically inadequate. He ultimately seeks to reform or overthrow the World Government so ordinary people can live without slavery, exploitation, forced marriage, or arbitrary noble rule. 2 11 17 18

Yang can be compassionate and principled: he refused to deceive the Glazed Town mayor about the value of a Devil Fruit, directs intelligence networks toward civilian protection, and insists that his organization should not ally with openly oppressive groups. 16 40 43 However, he is also willing to use threats, surveillance, bribery, infiltration, framing, and assassination to pursue his goals. 35 37 41

Abilities & Skills

Justice System

The Justice System recognizes Yang’s own beliefs as its standard of justice. It provides basic rewards and lottery opportunities whenever he advances in an organization. 2

• Promotions comprehensively improve his physical strength, stamina, recovery, cognition, eyesight, reflexes, storage capacity, map range, AI capability, and Justice Gauge limit. 13
• Each promotion normally doubles his Dao Power, which Yang describes as a form of “perfect evolution.” 13
• Justice Value is earned through righteous acts and can fund lotteries; a full gauge may create a guaranteed promotion opportunity. 2
• The system removes the embedded will from Devil Fruits Yang consumes without removing their powers. 29

Color-Color Fruit

Yang’s first Devil Fruit is the Paramecia Color-Color Fruit, which controls and alters colors. 2

• Can alter the colors of objects and environments. 2
• Yang identifies transparency or invisibility as its most basic potential application. 2
• He theorizes that altered light transmission, air-borne lenses, concentrated sunlight, and ultraviolet radiation could become offensive applications. These uses remain speculative. 2

Door-Door Fruit

Yang exchanged the Cloud-Cloud Fruit for the Paramecia Door-Door Fruit and developed it far beyond ordinary door creation. 19 28 29

• Opens doors through walls, structures, and living bodies. 29
• Creates a separate spatial dimension for storage, concealment, surveillance, and shelter. 29
• Developed Spark Portal, a golden-spark gateway inspired by fictional magic portals. It can vary in size, direction, and placement, and its edges can cut objects. 31
• Spark Portals consume stamina; larger, longer-distance portals require more energy, cannot be moved after creation, and initially demanded hand gestures and heavy concentration. 31
• Developed Spirit World, a green dimensional storage realm. It is location-bound, airless, weightless, and unsuitable for long-term habitation. 32
• Developed a Devil Fruit-based Portable Space roughly the size of a football field and nearly twenty meters high, capable of storing an entire ship. 32
• Developed Dimensional Roaming, allowing concealed movement through dimensional space at speeds exceeding 300 m/s. 32
• Developed an incomplete Mirror Space containing realistic but intangible projections that cannot be physically interacted with or manipulated. 32

Byakugan

Yang acquired the Byakugan through a promotion lottery and fused it directly into his body. 13 14

• Provides passive 360-degree vision, extraordinary clarity, and X-ray sight. 14
• Initially possessed approximately 4 km of precise observation range; the range expands with his system-enhanced body and was later measured at roughly 64 km. 14 50
• Allows him to inspect sealed containers, scan entire islands, observe through walls, and locate hidden individuals. 16 33
• He cannot cultivate chakra in the One Piece world and suspects its world laws prevent the necessary energy framework. 14

Combat Training

System-granted skills provide Yang with knowledge and muscle memory rather than merely increasing raw power.

• Basic Shooting — Firearms, aiming, trajectories, wind calculations, throwing, and archery; initially allows reliable shots within roughly fifty meters. 6
• Basic Swordsmanship — Offensive, defensive, and footwork techniques designed around an Eight-sided Han Sword. 13
• Basic Body Arts — Structured striking, palm, elbow, leg, kick, and footwork techniques. 21
• Intermediate Shooting — Includes gun-fu, long-range sniping, rapid archery, volleys, and arcing shots. 24
• Intermediate Swordsmanship — Adds advanced sword schools emphasizing speed, defense, movement, and specialized techniques. 24
• Intermediate Martial Arts — Enables more refined force control, including advanced Eight Trigrams Palm applications and deceptive shifting of balance and attack angles. 49 50

Hell’s Curse

Hell’s Curse is a passive lottery skill that collects souls from beings Yang kills. 6

• Ordinary living beings have a stated 50% chance to drop a soul, while elite beings guarantee one. 6
• Each soul grants 0.75 Spell Power and 0.75 Armor. 6
• After the Blood Knife Pirates’ defeat, Yang possessed 64.5 Spell Power and Armor from 86 collected souls. 50
• Spell Power functions as a broad coefficient that improves system abilities, physical efficiency, metabolism, neural transmission, and recovery. 50
• Armor provides a permanent defensive enhancement rather than an activated technique. 50

Great Yin-Yang Art

The Great Yin-Yang Art is a dual-cultivation technique obtained through a promotion lottery. 24

• Absorbs Yin-Yang Energy through cultivation with a female partner. 24
• Strengthens life essence, vitality, physical condition, and youthfulness; long-term mastery may form an Acquired Yin-Yang Body and grant immortality. 24
• Its effects enhanced both Yang and Hina despite neither possessing internal energy, true qi, or Armament Haki. 27
• The exact reason it functions in the One Piece world remains unknown. 27

Intelligence Network Operations

Yang directs a decentralized intelligence structure built around Little Bean’s Link-Link Fruit communications. 33 41

• Uses linked informants, DD Chat, encrypted communication, synchronized meetings, and the Combat Command System. 33 41 46
• Recruits socially overlooked observers—including orphans, beggars, dockworkers, newspaper sellers, and elderly residents—whose daily work gives them access to useful information. 33 43
• Employs detailed reconnaissance, terrain analysis, informants, faction mapping, and enemy profiling to plan Marine operations. 45
• The Loyalty Link effect strengthens linked individuals’ attachment to higher-level users, complicating the sincerity of their loyalty. 34 41

Equipment

• Thundering Pulse — A five-star bow-and-blade weapon that forms lightning arrows without ammunition, increases attack power and critical damage, and gains stacking bonuses through normal attacks. 22
• Thunder Emperor — A Pod from the NieR:Automata universe integrated with Little Bean; possesses quantum computing, flight, anti-gravity and nuclear-fusion engines, lasers, imaging, and communications support. 24
• Zephyr — A jade feather pendant that increases movement speed, attack speed, attack power, mental recovery, and resistance to control effects. 49
• Cloudstream — A Fine Grade Blade obtained through a Justice Value draw. 49
• Insight — A powerful sniper rifle obtained through a Justice Value draw. 49
• Portable Space — System storage that freezes time for stored items and can preserve living creatures; storage requires bare-skin contact, though Yang’s hair qualifies. 3

Military and Organizational Reforms

• Rebuilt Base 36’s recruitment through newspaper advertising and expanded its force to 352 Marines, including reserves. 6 28
• Introduced literacy classes so recruits could understand military regulations and eventually qualify for specialized work. 21 22
• Adapted eleven disciplinary rules emphasizing civilian protection, fair payment, property preservation, respectful conduct, and humane treatment of prisoners. 22
• Added formation training, saluting, marching, goose-stepping, orderly quarters, and standardized unit organization. 23 25 45
• Reformed procurement by purchasing directly from Glazed Town farmers and Gem Country fishermen, eliminating corrupt middlemen and redirecting savings toward allowances, death benefits, and intelligence work. 23 25
• Created detailed combat conferences, a company-platoon-squad structure, holographic tactical briefings, and the secret Combat Command System. 45 46
• Planned a hospital network that would provide public healthcare, support intelligence gathering, and allow ethical accumulation of Hell’s Curse souls from natural deaths. 50

Relationships

• Hina — His commanding officer, ideological confidante, girlfriend, and partner in opposing the World Government. Yang helped reshape her understanding of justice and develop the Cage-Cage Fruit’s sealing potential; their relationship became public knowledge at Base 36. 11 17 25 27
• Little Bean — Yang’s soul-bound Personal AI and closest technological partner. She manages communications, analysis, links, interfaces, and Thunder Emperor, and displays emotional attachment and jealousy toward him. 2 24 42
• Nico Robin / “Miss Rebecca” — Recruited historian, executive secretary, and DD Organization member codenamed “Historian.” Yang offers her protection, a new identity, and support for researching the Void Century; she gradually chooses to trust him. 36 39 41
• Bezos — Intelligence chief codenamed “Eyes and Ears.” Yang recognized Bezos’s informal network on Ghost Mulberry Island and gave him funding, communications, and authority to expand it across West Blue. 33 34 41
• Gion — Vice Admiral who exchanged the Door-Door Fruit for Yang’s Cloud-Cloud Fruit. She delivered Tsuru’s offer to transfer Yang to Marine Headquarters, which he declined. 19 28 29
• Luo Ma and Luo Niu — The Ox-Horse Brothers entrusted to Yang by Glazed Town’s mayor. He accepted responsibility for their Marine registration and later relied on Luo Ma as a unit commander. 16 46
• Ajilu Celo and the Celo Five — Recruited from poverty on Cinnamon Island after Yang tested and defeated them. They became linked operatives and the foundation of his planned pirate training unit. 37
• Yang’s parents — Supportive but fearful parents from the Flower Country. They wanted him to live safely as a fisherman; Yang left home to pursue Marine service and his larger ambitions. 1 4
• Little Black — Loyal employee who found Yang’s first Devil Fruit, researched Marine bases, purchased his escape passage, and cared for Yang’s house after his departure. 1 3 4
