Bai Ye

Biodata

Power Progression

Physique and Constitution refer to the same upgraded attribute in the supplied system panels.

Background / History

Bai Ye transmigrates into the One-Punch Man world with his original appearance intact. The system supplies Dual Kamui, an existing C-Class hero identity, and a home next to Saitama. He recognizes Saitama immediately but conceals his prior knowledge of the setting 1 10.

His assigned hero identity is already close to expulsion for inactivity: he has only 24 hours to perform qualifying hero work. Initially, his ordinary physique makes even a few Kamui uses exhausting, so earning points and strengthening himself become urgent priorities 1 2.

Bai Ye does not intend to settle for survival through intangibility or hiding in the Kamui Dimension. Although he regards Saitama as unlikely to become an enemy, he wants enough strength to confront threats such as Boros directly 6.

Appearance

Bai Ye retains his pre-transmigration features: a clean-cut face and short black hair resembling Obito Uchiha’s hairstyle 1.

• Normal eyes: Black; he can return to them at will 1.
• Original Mangekyō pattern: Scarlet eyes with three connected sickle-shaped blades, matching Obito’s Kamui pattern in both eyes 1.
• Eternal Mangekyō pattern: A combined design formed by merging his original pattern with Shisui’s shuriken-like Mangekyō 47.
• Infiltration disguise: A red Tiger-Striped Mask worn during his Monster Association investigation 50.

Personality

Bai Ye is pragmatic about growth, treating monster encounters, exploration, and even contests as opportunities to earn system points. He often saves purchases until combat requires them, yet also undertakes demanding training rather than relying entirely on immediate upgrades 6 18 20 36.

He is hospitable and encouraging: he regularly feeds Saitama, helps him avoid unnecessary travel costs, and reassures a would-be hero that protecting others already makes him heroic. His teasing can be excessive, but he returns to help Lily after realizing he has frightened her into tears 5 7 20 26 27.

He rejects status-based intimidation and forced recruitment. While willing to defend himself harshly, he distinguishes voluntary cooperation from coercion, telling Fubuki that forming a group is acceptable so long as she neither forces people to join nor suppresses outsiders 35 38 40.

Abilities & Skills

System and Points Shop

Bai Ye’s system supplies abilities, purchases, inventory storage, and rewards for qualifying achievements 1 33 50.

• Point sources: Combat, contact with major characters, hidden achievements, first-time location visits, promotion, and competitions—including video games 1 10 11 21.
• Physique upgrades: Increase strength, speed, and mental energy; cost one point per unit and can be stacked without a stated limit 1.
• Direct mastery: Flying Thunder God and basic Body Flicker are granted without a conventional learning period, although practical proficiency still benefits from training 11 18.
• Growth Incentive: Grants corresponding rewards as Genos advances through the hero rankings 33.

Sharingan and Eternal Mangekyō Sharingan

His Sharingan provides enhanced perception and movement prediction. Because Bai Ye has no chakra, the system substitutes mental energy and ocular power for its normal consumption 1 9.

• Can switch between normal eyes, Three-Tomoe Sharingan, and Mangekyō Sharingan by thought 1.
• Predicts attacks from preparatory movements, allowing him to evade both Tank-Top brothers 9.
• Improves precision when throwing kunai and gives him a substantial advantage in video games 18 21.
• The Eternal Mangekyō greatly increases ocular power and removes the ocular-technique side effects described before fusion 47.
• Genjutsu: Used to control Vaccine Man after his defeat 22.
• Kotoamatsukami: Listed among his abilities after fusion with Shisui’s eyes; its use is not shown in the supplied passages 47.

Dual Kamui

Dual Kamui combines dimensional transportation, intangibility, and spatial attacks 5 11.

• Intangibility: Transfers his body into the Kamui Dimension so attacks in the real world pass through him 5 22.
• Dimensional capture: Draws targets into the Kamui Dimension; capturing Potato Monster is sufficient for the system to register victory 3.
• Multiple portals: Intercepts Vaccine Man’s light orbs simultaneously and transfers them away 22.
• Spatial severing: Can ignore physical defenses, including when applied to a weapon or another technique 11 22 44 45.
• Transportation: Travels through the Kamui Dimension as an intermediate point. Previously visited destinations allow precise travel; unfamiliar destinations require hazardous blind teleportation 10.
• Vulnerability: During intangibility, his transferred body is defenseless inside the Kamui Dimension. Keeping a hostile prisoner there can therefore endanger him 5.
• Energy demands: Repeated use drains mental energy; early blind-teleport exploration leaves him nearly exhausted despite substantial upgrades 1 10.

Flying Thunder God Technique

An S-rank space-time technique granted upon promotion to B-Class. Its formulas are mental-energy marks rather than chakra marks 11.

• Instantly teleports to marked people or objects without passing through the Kamui Dimension 11.
• Uses a distinctive formula matching his Mangekyō pattern 13 18.
• Supports rescue operations, battlefield repositioning, and attacks from an opponent’s blind spot 13 22 44.
• Flying Thunder God Slash: Combines teleportation to a marked kunai with a sudden sword strike 22.
• Marks Saitama’s back—with permission—to locate and retrieve him after he repeatedly gets lost 20.

Body Flicker Technique

Uses mental energy to energize his body for high-speed movement 18.

• Speed depends on physical fitness and mental-energy strength 18.
• Trains by moving between cities while throwing kunai at small, precise targets 18 19.
• Combines ordinary high-speed movement with Flying Thunder God’s instantaneous repositioning 18.
• His post-fusion panel lists both Basic and Shisui versions; the supplied passages do not separately demonstrate Shisui’s version 47.

Hashirama Cells and Wood Clone

Hashirama cells improve his abilities and automatically restore physical injuries, mental energy, ocular power, and eyesight 1 4.

• Purchased in trace units for ten points each, with no stated stacking limit 1.
• Before Eternal Mangekyō fusion, recovery helps prevent blindness provided he does not severely overuse his ocular techniques at once 4.
• Reaching 20 units unlocks Wood Release: Wood Clone 36.
• Sends a Wood Clone to accompany Vaccine Man on a shopping trip 41.

Rasengan and Kamui Rasengan

Rasengan compresses mental energy moving in different directions into a dense sphere 44.

• Purchases the technique for 50 points 36.
• Infusing it with Kamui turns it into a black energy sphere that effortlessly pierces Carnage Kabuto’s armor and abdomen 44.
• Can throw a Kamui Rasengan rather than only deliver it at close range 45.

Susanoo

A blue-green giant manifested from mental energy rather than chakra 37 45.

• Second stage: A 20–30-meter half-bodied form with flesh, a mental-energy cloak, and two giant swords 37.
• Third stage: Adds Tengu Armor, greatly improving defense without substantially increasing size 45.
• Withstands Asura Mode Carnage Kabuto’s repeated punches 45.
• Kamui-infused dual blades cut Carnage Kabuto into four pieces with an X-shaped slash 45.

Equipment / Weapons / Items

• Red Night Blade — A katana stronger than ordinary weapons, purchased for ten points. Bai Ye coats its edge with Kamui to cut through physical defenses 1 6 22.
• Fourth Hokage’s Kunai — Three-pronged kunai purchased in batches of ten for one point; marked with Flying Thunder God formulas for training and combat 18 22.
• Tiger-Striped Mask — A durable, one-point red mask used for infiltration. Its single eyehole does not obstruct either eye’s vision or ocular techniques 50.
• Mobile phone — Connected to Hero Association alerts and used for contact with Saitama and Lily 6 20 28.
• System-provided bank card — Initially holds 100,000 yen, which he uses to buy dinner ingredients 5.

Relationships

• Saitama — Neighbor, frequent dinner guest, gaming partner, and training companion. Bai Ye knows his true strength and retrieves him when he gets lost 1 5 19 20 21.
• Genos — Persistent disciple whom Bai Ye initially tries to redirect toward Saitama. Bai Ye eventually permits him to follow without promising instruction; the system nevertheless recognizes the apprenticeship 32 33. Later, he recommends powerful opponents and mental resilience as routes to growth 48.
• Vaccine Man — Defeated opponent placed under genjutsu control who subsequently spends time at Bai Ye’s home. His Monster Association invitation becomes Bai Ye’s opportunity to infiltrate the organization 22 32 41 50.
• Fubuki / Hellish Blizzard — Initially attempts to recruit him by force. After defeating her and rescuing her from House of Evolution attackers, Bai Ye challenges her coercive methods; she later visits and asks for training advice 35 36 37 40 48.
• Lily — Blizzard Group recruiter whom he teases, then rescues from the outskirts. They exchange contact details, although he continues rejecting her recruitment efforts 26 27 28 29.
• Mumen Rider — Promotion-match opponent who surrenders and subsequently defends Bai Ye against accusations of cheating 7 8.
• Tank-Top Tiger and Tank-Top Black Hole — Antagonistic heroes who challenge his legitimacy. Bai Ye defeats them together to settle the dispute quickly 2 8 9.
• Bang — Receives Bai Ye hospitably after an accidental teleport into his dojo. Offers martial-arts instruction, which Bai Ye politely declines 12 13.
• Dr. Genus — Targets Bai Ye for research through the House of Evolution. After Carnage Kabuto’s defeat, questions whether Bai Ye’s strength came from experimentation 37 45.
