Power Progression

Stage / Realm / Level	Chapter	Notes
Ten Shadows Technique awakening	3	Awakens on his fifth birthday, approximately one year before Naobito discovers it. By six, he controls Divine Dogs: Black and White.
Wind-based Divine Dog techniques	4 5	Black develops offensive Wind Blades, while White produces a spinning Wind Shield. His council demonstration shows improved coordination, precise damage control, and defense against probing cursed energy.
Rabbit Escape and Toad confirmed	7	Reveals two previously hidden shikigami during Nue’s subjugation. Their acquisition dates are not given.
Nue subjugated	7	Uses Rabbit Escape as a distraction, Toads to bind Nue’s wings, and the Divine Dogs to attack its core before establishing the contract.
First documented Grade 2 victory	10	Finishes Toji’s survival test by spending his remaining cursed energy on Nue’s lightning. Wins but collapses from exhaustion.
Close-combat improvement	12 13	A month of technique-free sparring with Toji develops his stance, impact handling, evasion, and counterattacks. He remains physically outmatched by his teacher.
Reliable Grade 2 exorcism	14	Ordinary Grade 2 cursed spirits have become effortless opponents after sustained training.
Source Exchange breakthrough	15	Exchanges portions of his source with Divine Dogs, Toad, Rabbit Escape, and Nue. Gains direct access to their abilities without summoning or hand signs, with greatly reduced energy expenditure. His confidence against Grade 1 curses is an assessment, not a documented rank promotion.

Round Deer and healing confirmed	33 44	Summons Round Deer to remove the group’s injuries and fatigue. Later explains that his Reverse Cursed Technique comes from the shikigami rather than independent learning.
Controlled Grade 1 neutralization	37	Blocks a flame-wielding Grade 1 curse with water, then incapacitates it using a white-flame gardenia, preserving it for Geto to absorb.

Background / History

Zenin succession

Zhiyan grows up at the Zenin estate as Naobito’s son. He keeps his Ten Shadows awakening private for roughly a year, considering the technique his own responsibility rather than something he must report. Once Naobito discovers it, he tests the Divine Dogs and begins preparing Zhiyan for succession 3 4.

At six, Zhiyan answers objections to his age with a controlled demonstration before the clan council. His dogs alternate wind attacks and defenses, carve the clan crest into a pillar, and repel the elders’ probing cursed energy. Naobito declares him the official heir, with an investiture ceremony to follow 5.

The appointment exposes him to internal hostility. His uncle Ogi resents losing the prospect of leadership and unsuccessfully attempts to enlist Toji’s support. Toji warns Zhiyan about the scheme after easily dismantling his attacks, forcing him to recognize how much his inherited technique still depends on training and judgment 5 6.

Training under Toji

After his investiture, Zhiyan rejects Naobito’s proposed tutors as too conventional, narrowly specialized, or interested in his status rather than teaching him. He instead recruits Toji, accepting dangerous training and offering access to Zenin resources in exchange. Naobito accepts the choice despite its likely political consequences 8 9.

Toji’s instruction begins with a Grade 2 survival test and progresses to punishing hand-to-hand combat. Zhiyan learns to abandon rigid shikigami roles, make decisions in real time, and survive when his preferred technique is unavailable. When Ogi later pressures him to sever the relationship, Zhiyan defends his training and orders his uncle to attend to his own duties 9 10 12 13.

Toji also provides the idea that leads to Source Exchange. Zhiyan’s first attempt at complete core fusion nearly destroys the Divine Dogs, so he replaces it with a reciprocal exchange of small source portions. The successful method becomes the foundation of his later fighting style 14 15.

Shoko’s protection and engagement

During an outing with Wana, Zhiyan meets Shoko Ieiri after she gives his sister a serving of daifuku. On a later visit, he recognizes Shoko’s ability to heal a sparrow as Reverse Cursed Technique and explains the implications of entering jujutsu society 16 17 18.

When Jujutsu Headquarters demands Shoko, Zhiyan proposes an engagement to establish her place within the Zenin Clan. He makes clear to her father that it is a protective arrangement and that he will not object if Shoko later chooses to end it. Both children agree to the engagement 21 22.

His concern develops into affection. He arranges a furnished Kyoto home for Shoko’s parents and helps them relocate, protecting the family without separating them from their daughter. At the Three Great Families’ banquet, he publicly identifies Shoko as his fiancée when Gojo questions her background 23 25.

Childhood rivals and friends

At the banquet, Zhiyan defeats Kamo Xian Di while learning from his Blood Manipulation. His sincere praise afterward establishes mutual respect. He then accepts Gojo’s challenge; their escalating exchange ends with both exhausted and agreeing to a draw 26 27.

Although Zhiyan acknowledges Gojo’s current advantage, the match awakens a competitive interest that his father’s earlier comparisons had failed to inspire. Two days later, Gojo visits his courtyard and insistently declares them friends. Zhiyan eventually accepts, beginning a lasting friendship shared with Xian Di, Shoko, and Wana 4 27 28.

Tokyo Jujutsu High

At sixteen, Zhiyan chooses Tokyo Jujutsu High alongside Gojo and Xian Di to gain distance from Headquarters’ scrutiny in Kyoto. Shoko also attends, and Wana travels with the group. Their first-year class consists of the five childhood companions and Suguru Geto, under Masamichi Yaga 29 30 32.

During their first mission, Zhiyan supports Geto on the western side of an abandoned chemical plant. He deliberately leaves a Grade 1 curse alive after incapacitating it so Geto can absorb it, following his earlier suggestion that the team preserve suitable curses for Geto’s technique 35 37.

He later reconnects with Toji and discovers his former teacher’s peaceful household with Zhuzhi and their son Megumi. After hearing how marriage changed Toji’s outlook, Zhiyan accepts that his cousin has found genuine happiness 41 42.

At the Goodwill Event, his restraint is tested when Shinya wounds Wana with a concealed cursed tool. Zhiyan orders an enraged Gojo to remain seated, though his clenched fist reveals his own anger and worry. Wana’s match remains unresolved at the end of the supplied account 50.

Appearance

• Hair and eyes: Black hair, shown falling over his shoulders during childhood; dark eyes framed by ink-black lashes 3 5 8.
• Facial features: A prominent brow ridge, slightly upturned outer eye corners, a high straight nose, thin lips, and a sharply defined jawline 29.
• Build: Toji’s early training adds a thin layer of muscle to his formerly slender arms and makes his movements visibly firmer and more efficient 13.
• Bearing: Usually composed and distant; his expression becomes noticeably gentler when he smiles or looks at Shoko and Wana 5 25 29.
• Clothing: Wears kimono at the clan estate and formal family gatherings, and a school uniform at Jujutsu High 7 25 34.

Personality

Zhiyan is reserved, proud, and unusually self-possessed from childhood. He resists intrusive affection, conceals advances in his technique, and refuses to accept that his father or clan automatically has authority over his training choices. He views the heir position chiefly as access to resources, not a prize of prestige 3 7 8 11.

His ambition centers on autonomy and protecting people he values. He initially rejects rivalry with Gojo in favor of mastering his own technique, but later enjoys competing with someone who genuinely challenges him. He accepts criticism from Toji, acknowledges Gojo’s advantage, and takes his later martial-arts loss to Xian Di graciously 4 6 27 33.

His warmth appears most clearly in practical care: guarding Wana, reassuring her after danger, supporting her friendships, and arranging safety and housing for Shoko’s family. Around Shoko, his solemn manner gradually gives way to smiles, embarrassment, and playful retaliation 16 17 23 29.

His composure does not mean an absence of anger. He slaps Shinya for insulting Shoko and subjects Gojo to a humiliating, carefully healed beating after provocative teasing. Nevertheless, he explicitly supports Shoko’s choices and restrains Gojo from interrupting Wana’s dangerous match 47 49 50.

Abilities & Skills

Ten Shadows Technique

Zhiyan summons and coordinates shikigami through his inherited Zenin technique. His training emphasizes combining their functions rather than merely increasing their number 3 9 10.

Shikigami	Documented abilities and uses
Divine Dogs: Black and White	Perception, speed, claws and biting attacks; wind offense and defense. Black produces Wind Blades, while White uses a spinning Wind Shield and guards Wana 4 13 15.
Toad	Mucus-coated tongues for binding, restraint, and protection; later used to suspend Gojo upside down 7 9 47.
Rabbit Escape	Numerous agile duplicates for distraction, concealment, disruption, and evasion 7 10 15 27.
Nue	Lightning attacks; his most destructive shikigami during early training 10 15.
Great Serpent	Ground reshaping and earth-based battlefield control, used to trap Gojo 16 27.
Max Elephant	Water production and control; its large body also shields him from ranged attacks 26 37.
Round Deer	Healing through Reverse Cursed Technique, including removal of injuries and fatigue 33 44.

• Early limitation: White’s Wind Shield depends on uninterrupted airflow, and the dogs initially struggle with coordinated timing 4.
• Energy management: Prolonged multi-shikigami combat can exhaust his early reserves; his first Grade 2 victory leaves him unable to stand safely 10 11.
• Mahoraga: Zhiyan identifies its absence as a barrier to overcoming Gojo’s Limitless during their childhood match 27.

Source Exchange

Source Exchange swaps a small portion of Zhiyan’s cursed-energy source with a shikigami’s, establishing a stable, reciprocal connection rather than consuming either participant 14 15.

• Uses exchanged abilities through thought alone, without summoning, hand signs, or a cursed-energy bridge 15.
• Grants Divine Dog perception, speed, claws, and wind; Toad’s restraint abilities; Rabbit Escape’s duplicates; and Nue’s lightning 15.
• Reduces cursed-energy expenditure to a minimum and increases the speed of accessing shikigami power severalfold 15.
• Initially allows him to perceive minute activity within a hundred meters beyond his courtyard; later supports vigilant monitoring during city outings 15 16.
• Expands to Great Serpent and Max Elephant after three years of training 16.
• Limit: Complete source fusion causes violent rejection and threatens to erase the shikigami. The successful method requires controlled partial exchange 14 15.

Elemental Techniques

• Wind Blades: Precisely cuts through attackers’ cursed-energy pathways, disabling Curse Users without summoning the Divine Dogs 16.
• Compressed water projectile: Applies Piercing Blood’s observed principles to Max Elephant’s water. This is an adaptation of its mechanics, not demonstrated possession of Blood Manipulation 26.
• Combined elemental barrage: Produces arrows incorporating water, lightning, wind, and earth against Gojo 27.
• Water barrier: Blocks a Grade 1 curse’s blue-flame attacks 37.
• White-flame gardenia: Engulfs and incapacitates that curse without killing it. Its source and wider limitations are not explained in the supplied account 37.

Reverse Cursed Technique

His healing comes from Round Deer rather than independently learned Reverse Cursed Technique 44.

• Heals the students’ injuries and fatigue after combat training 33.
• Repeatedly heals Gojo during a controlled punishment, minimizing lasting damage 47.
• Explains the underlying principle as multiplication of negative cursed energy, but does not provide a practical step-by-step method 44.

Martial Arts and Tactical Analysis

• Learns footwork, impact handling, stance retention, rhythm, and counterattacks through Toji’s technique-free training 12 13.
• Reinforces strikes and landings with precisely controlled cursed energy 26.
• Adapts shikigami assignments to an opponent’s movements instead of following fixed clan doctrine 9 10.
• Observes an unfamiliar attack’s energy flow, compression, release timing, and trajectory closely enough to reproduce its principles 26.
• Limit: Xian Di defeats him in a technique-restricted school spar through superior martial arts and stamina 33.

Shadow Storage

• Stores physical belongings in his shadow space, including Shoko’s collection of more than twenty or thirty bottles of alcohol 29.
• Shoko jokingly calls it his “cartoon pocket” 29.

Equipment / Weapons / Items

• Handmade maple-leaf bookmark — A gift from Wana, delivered by Shoko; Zhiyan examines it and carefully puts it away 24.
• Books and jujutsu dossiers — Regularly reads technique material, case files, and Jujutsu Society records in his study and courtyard 3 21 24.
• Celadon tea set — Used during his courtyard routine and visits from friends and relatives 24 28.

Relationships

• Naobito Zenin — Father and clan head. Publicly secures Zhiyan’s succession, provides early technical guidance, and supports his choice of Toji despite political concerns 3 5 9 13.
• Wana Zenin — Younger sister. Zhiyan protects her, promises to teach her jujutsu, and supports her friendship with Shoko; her affection regularly softens his reserved manner 4 13 16 17.
• His mother — Offers emotional support after the council and reminds him that he is still a child who need not carry every burden alone 5.
• Toji Zenin — Cousin and former teacher. Challenges his reliance on inheritance, inspires Source Exchange, and develops genuine regard for him beneath their abrasive banter 6 8 14 24 42.
• Shoko Ieiri — Fiancée and childhood companion. Their protective engagement develops into mutual affection; Zhiyan respects her right to end the arrangement and later affirms his support for her independent choices 22 23 29 47.
• Satoru Gojo — Friend and rival. Their first match awakens Zhiyan’s competitive spirit, while Gojo’s persistent teasing frequently tests his patience 27 28 47.
• Kamo Xian Di — Longtime friend and sparring partner. Their first duel establishes mutual respect, and Xian Di later wins their technique-restricted martial-arts match 26 28 33.
• Suguru Geto — Classmate, friend, and mission partner. Zhiyan supports the growth of Geto’s curse collection by preserving weakened spirits for absorption 30 35 37.
• Masamichi Yaga — Homeroom teacher. Oversees combat assessment and assigns the class’s first field mission 32 33 34.
• Ogi Zenin — Uncle and succession opponent. Resents Zhiyan’s inheritance and tries unsuccessfully to pressure him into abandoning Toji’s instruction 5 6 13.
• Shinya Zenin — Younger cousin who envies his status and affection for Shoko. Zhiyan publicly punishes his insult toward her; Shinya later wounds Wana during the Goodwill Event 26 49 50.
• Megumi Zenin and Zhuzhi — Toji’s son and wife. Meeting them reveals a domestic side of Toji that Zhiyan had not expected 41 42.
