Background / History

Piyu first investigates the connection between Bai Zhu’s Silver-White Tail Feather and the One-Eyed Bird Emblem. Her phone scan shows the emblem’s feather pattern flashing in synchronization with Bai Zhu’s feather, leading her to suspect that it is more than an accessory 174.

She joins Ging’s expedition toward the Lakeheart Oasis and Black Tower as the team’s specialist in locating writing and interpreting inscriptions. Her research identifies the previous corpse-recovery route through the black-soil forest, while her documentation helps establish the ruins’ significance 184.

During the Black Tower crisis, Piyu becomes interested in Milluki’s recordings of Bai Zhu’s cross-system combat. She attempts to purchase the entire collection, including high-definition and tactical-analysis versions, though she questions whether Bai Zhu consented to their sale 205.

Appearance

Piyu is most readily recognized by the rabbit-ear hair tie/accessory she wears. She almost always carries a phone or terminal for scanning, filming, recording evidence, and managing investigation data.

• Rabbit-ear hair tie, which Milluki and Dwun openly notice 214.
• Frequently records events on her phone, including dangerous battles and ancient-site discoveries 181 186.
• Is described by Milluki as a “beautiful bunny girl” 179.

Personality

Piyu is observant, fearless, and relentlessly curious. She routinely presses Bai Zhu for information about his abilities, scans suspicious artifacts, and treats unusual events as valuable research material even when others consider them life-threatening 175 181.

Her teasing is sharp and persistent. She records embarrassing remarks, mocks Bai Zhu’s grandstanding, and bargains aggressively with Milluki over footage and contracts. However, her humor does not prevent her from recognizing danger quickly or taking responsibility when others are vulnerable 184 205 281.

Piyu is also principled. She refuses to abandon missing investigators in NGL, arguing that Hunters cannot retreat every time their work becomes dangerous 342. When Unma attempts to exploit Bai Zhu while he is unconscious, Piyu intervenes immediately, preserves evidence, and forces the royal family to face the consequences 281 283.

Abilities & Skills

Enhancement-Type Nen

Piyu is an Enhancement-type Nen user whose physical combat ability greatly exceeds what her scholarly role initially suggests 292.

• Produces a phantom of enormous rabbit legs when attacking, including the kick that shattered Unma’s Nen Beast armor 281.
• Fights effectively underwater, clearing swarms of golden-particle-infected sea life with powerful kicks 292.
• Can carry the unconscious Bai Zhu through Husk-infested streets while fighting and evading gunfire 282.
• Uses close-quarters speed and force to pressure the Holy Seat Proxy, crushing several embedded faces with a kick 357.

Archaeology, Linguistics, and Investigation

Piyu specializes in ancient texts, inscriptions, historical evidence, and intelligence gathering.

• Identifies the feather-pattern resonance between the One-Eyed Bird Emblem and Bai Zhu’s Silver-White Tail Feather 174.
• Locates writing and traces the route of an earlier recovery team inside the black-soil forest 184.
• Interprets damaged gate inscriptions and determines that the Black Tower entrance functions more like a maintenance access point than a defensive barrier 216.
• Uses public procurement archives, shipping records, and her media identity to investigate Kakin’s marine engineering and royal experimentation networks 252 253.
• Recognizes that the Black Gate’s inscriptions belong to the same sealing system found in earlier ruins 351.

Documentation and Evidence Handling

Piyu’s phone is both a research tool and a source of battlefield evidence.

• Records Bai Zhu’s combat despite his repeated objections 181.
• Uploads footage of Unma attempting to draw Bai Zhu’s blood to the Hunter Association’s encrypted server 281.
• Uses the footage, the royal sampling vehicles, and falsified reports to expose the attempt to frame Bai Zhu as the source of Kakin’s disaster 283.
• Continues documenting cross-system phenomena, including Bai Zhu’s Reishi roadway 215.

Tactical Judgment

Piyu often balances Bai Zhu’s impulsiveness with practical battlefield decisions.

• Prevents Bai Zhu from prematurely attacking the Silver Candle Envoy before the fortress’s escape routes are identified 351.
• Identifies that Hecatos’s black crows grow stronger through fear and protects Milluki while he is overwhelmed by hallucinations 293.
• Takes command during the underwater approach to the Chimera Ruins, assigning Bai Zhu to clear the route and Milluki to manage equipment 292.
• Rejects reckless entry into the Black Gate and offers to scout first, though Bai Zhu ultimately enters alone 361.

Equipment / Items

• Phone/terminal — Used for artifact scans, filming, encrypted evidence uploads, research records, and communications 174 281.
• Rabbit-ear hair tie — Her most recognizable accessory 214.
• Hunter License — Used to assert her Zodiac authority during the Kakin quarantine crisis 283.

Relationships

• Bai Zhu — Teasing teammate and frequent subject of her recordings. She challenges his secrecy and recklessness, but repeatedly protects him, including carrying him out of Unma’s facility and exposing Unma’s attempted blood extraction 181 281 284.
• Milluki Zoldyck — Fellow investigator and frequent bargaining partner. Piyu tries to buy his combat footage, works with his surveillance technology, and protects him from Hecatos’s fear-born crows 205 217 293.
• Morel Mackernasey — Mission partner and practical mentor. Morel relies on Piyu’s organizational knowledge of Kakin’s elite services and intelligence channels 253 254.
• Shuto — Close ally during the Kakin Husk outbreak. Piyu and Shuto fight together while evacuating the unconscious Bai Zhu 282.
• Unma — Political adversary. Piyu attacks Unma after witnessing her attempt to drain Bai Zhu’s blood and threatens her with consequences if she refuses compensation 281.
• Knov — Tactical ally during the Creation Society operation. Piyu fights beside him against the Holy Seat Proxy and supports his increasingly exhausted spatial combat 357.
• Palm Siberia — Investigation partner. Piyu relies on Palm’s crystal-ball surveillance to locate the Golden Candle Envoy and monitor the Black Gate fortress 355.

Story Role / Major Arcs

Lakeheart Oasis and Black Tower Expedition

Piyu joins Ging’s team as an ancient-text specialist, investigates Bai Zhu’s resonance with the One-Eyed Bird Emblem, and helps document the dangerous journey into the Black Tower 174 184. During the Specialist Association ambush, she is repeatedly protected by Bai Zhu’s Dankū but remains intent on preserving her footage and research 200.

Kakin Royal Family Investigation

Using her Hunter Association and media identities, Piyu investigates Kakin’s marine engineering, charitable organizations, and royal research projects 252 253. She helps prepare Bai Zhu for social infiltration, manages aspects of his contract negotiations, and safeguards the agreement against Foundation interference 254 261.

Unma’s Betrayal and the Husk Disaster

After Bai Zhu defeats Slender Hound and collapses, Piyu catches Unma trying to extract his blood. She destroys the collection equipment, records the evidence, and carries Bai Zhu out of the facility 281. During the subsequent Husk outbreak, she protects the powerless Bai Zhu, challenges the military blockade, and helps establish a joint Hunter Association–military quarantine zone 282 283.

Chimera Ruins and Hecatos

Piyu reveals herself as an Enhancement-type fighter while helping Bai Zhu and Milluki reach the Chimera Ruins beneath the Caspian Sea 292. She recognizes Hecatos’s fear-based psychological attacks, shields Milluki from its crows, and remains outside the Stone Gate to support containment efforts 293 294.

NGL and the Creation Society

Piyu refuses to withdraw from the NGL investigation despite the danger to missing Association investigators 342. She restrains Bai Zhu’s urge for immediate revenge against the Silver Candle Envoy, supports Palm’s surveillance of the fortress, and leads the pursuit of the Golden Candle Envoy and the Black Box 351 355.

Notable Quotes

“If we turn back whenever there’s danger, the Association might as well rename itself a travel agency.” 342

“Bai Zhu cleaned up your mess for you, and this is how you repay him?” 281

Trivia

• Piyu’s first instinct after several attacks is often to protect her phone or its footage rather than herself 195 200.
• She briefly adopts an affectionate “big sister” persona solely to negotiate for Milluki’s combat recordings 205.
• Bai Zhu acknowledges that he would not actually silence her for recording him, partly because she runs too fast 184.
