Background / History

Sheng Jiu lost all memories from before the age of six and grew up in an orphanage in Changkong City. He suffered recurring nightmares and was ostracized by other children, while the orphanage director treated him normally and cared for him. During a Honkai outbreak, the director drew mutated students away so the children could escape; Sheng Jiu later returned to the abandoned orphanage and cremated the remaining bodies. 2 25

He was admitted to the all-girls St. Freya Academy as an exception because of his 95% Honkai Energy compatibility. Kiana Kaslana was assigned to show him around, and he joined Class 8 as her deskmate. 2 4

Appearance

Sheng Jiu is a black-haired young man whose appearance quickly draws attention among St. Freya’s students. After the battle with the Honkai Emperor, noticeable white strands appeared in his hair from exhaustion. 4 18

• Developed a strong, muscular physique through St. Freya training. 45
• During severe Honkai erosion, his right eye turned orange and golden-orange markings spread over the right side of his face. 28 30
• The erosion also caused patches of gray-white skin before Theresa treated him. 30
• Uses black Black Knight Mustafa God-Slayer Armor, whose one-eyed helmet and antennae give it a black-panther-like silhouette. 34 45

Personality

Sheng Jiu is outwardly lively, sarcastic, and fond of provoking Kiana with shameless jokes. He is competitive enough to attempt cheating during Hovos Duel, yet frequently turns serious when teammates are endangered. 5 35

He maintains an optimistic front even while injured, distressed, or confronting his past. His tendency to throw himself into danger—especially for Kiana—can become reckless, as shown by his use of Honkai Energy Amplifiers despite their risks. 13 17 42 43

Abilities & Skills

Extraordinary Reflexes

Sheng Jiu has possessed abnormally fast reactions since childhood. He perceives fast-moving attacks, including bullets, as unusually slow. 7

• Dodged Kiana’s bullets by minute movements.
• Caught a training bullet bare-handed.
• Split multiple bullets with a katana before most observers could follow his movements. 6
• Uses sudden movement and close-range positioning to create openings for allies. 16 24

Katana Combat

Sheng Jiu is a highly aggressive close-range fighter who favors katana attacks, direct charges, and improvised tactics.

• Defeated a Tank-type Honkai Beast by embedding blades into its body before Bronya’s artillery strike finished it. 16
• Held off a Honkai Emperor alone to protect Kiana and Rin, planting a spike in its torso that Kiana later used as a target. 17
• Used Jueying to sever a Loyal Ninja-Warrior Death’s weapon, arm, and head after coordinating with Kiana. 24
• Fought an Emperor-class Honkai Beast alongside the Manila rescue team. 42 43

Rapid Recovery

Sheng Jiu recovers from serious injuries at an abnormal rate.

• Recovered from severe wounds inflicted by the Honkai Emperor within two weeks. 18 20
• His recovery alarmed medical staff and drew Svet’s interest in studying his physiology. 19 20
• His resilience does not prevent Honkai erosion; attacks containing highly concentrated Honkai Energy can still critically endanger him. 28 30

Honkai Energy Erosion

After being scratched by the Pseudo-Herrscher Yunna’s poisonous vines, Sheng Jiu suffered rapid Honkai Energy erosion and risked becoming an emotionless Mortal. 28 30

• Yae Sakura’s anti-erosion pills delayed the transformation into a living dead. 28
• His worsening erosion briefly increased his physical strength enough to punch Yunna through a concrete wall. 30
• Theresa eventually removed the visible effects of the erosion through her transformed power. 30

Supernova Slash

A modified function of Jueying, Supernova Slash absorbs Sheng Jiu’s Honkai Energy and releases it as a powerful energy sword attack. 37

• Jueying’s blade separates and charges before releasing the attack. 37
• The system has five output levels; Sheng Jiu’s initial third-level use destroyed a holographic Paladin-type Honkai Beast. 37
• The technique causes severe exhaustion even at third level. 37
• Using fourth level after injecting two Honkai Energy Amplifiers shattered an Emperor-class Honkai Beast’s shield, but left him collapsed and bleeding. 42
• Further Amplifier use was dangerous enough for Kiana to warn that it could kill him. 43

Equipment / Weapons / Items

• Alloy Katana — early training weapon used during his duel with Kiana. 6
• Gale Katana — standard katana used during the Changkong City Honkai Beast tide. 16 17
• Gale Katana Kai: Absolute Shadow — weapon gifted by Himeko, forged using an Emperor-class Honkai Beast skull; it easily cut through a projected Tank-type Honkai Beast. 21
• Jueying — personal katana later modified with the Honkai Energy-absorbing Supernova Slash function. 22 36 37
• Black Knight Mustafa — fourth-generation God-Slayer Armor prototype designed specifically for male combat personnel. 34
• Achilles System — wrist-mounted armor deployment system that can instantly equip Mustafa, but its current operational limit is five minutes. 45
• Honkai Energy Amplifiers — injectable boosters Sheng Jiu used to raise Supernova Slash’s output at serious personal risk. 42 43
• Frozen Bomb Mk.1 — crystal bombs developed by Svet using Ice-element Emperor-class Honkai Beast tissue fluid; contact is intended to freeze targets permanently. 46
• Protective pendant — lent to Kiana before the Nine Nether mission because of Sheng Jiu’s superstitious concern for the team. 49

Relationships

• Kiana Kaslana — Deskmate, frequent rival, and closest teammate. Their constant arguments develop into mutual concern; Sheng Jiu repeatedly protects her in battle, while Kiana cares for him during his injuries and erosion. 2 6 17 19 30 43
• Theresa Apocalypse — Headmaster and protector who admitted him to St. Freya due to his compatibility. She later treated his Honkai erosion and intervened when Rita pressured him about joining Headquarters. 2 30 36
• Yae Sakura — Classmate and combat teammate who supports his missions. A shrine maiden Yae Sakura also provided anti-erosion pills and helped him survive Yunna’s attack. 7 16 28
• Bronya Zaychik — Teammate whose analysis confirmed Sheng Jiu’s unusual reflexes; she provides Heavy Trooper Bunny artillery and tactical support. 3 6 16 37
• Fu Hua — Class monitor whose first handshake with Sheng Jiu visibly unsettled her. She later saved the group by defeating the Honkai Emperor and led the Nine Nether expedition. 3 17 47
• Murata Himeko — Instructor who disciplines Sheng Jiu, gives him Absolute Shadow, and oversees the Achilles system test. 6 21 45
• Svet — Military doctor intrigued by Sheng Jiu’s rapid healing. She develops Frozen Bombs from the Emperor-class tissue fluid he recovered. 20 46
• Walter — History teacher whom Sheng Jiu finds strangely familiar despite Walter claiming they have never met. 5
• Otto Apocalypse — Met Sheng Jiu while concealing his identity as the Bishop of Schicksal. Otto arranged resources for the Far East Branch, supplied the Mustafa design, and invited Sheng Jiu to join Headquarters after graduation. 33 34 36
