Background and History

Su Bai and his younger sister, Su Xiaoxiao, live together after their parents’ deaths. At eighteen, he is a second-year Tianqiong University student who makes deliveries, trains intensely, and worries about student loans, rent, and Xiaoxiao’s school expenses 1 27.

He first transforms after trying Xiaoxiao’s homemade Magical Girl Transformation Guide while seeking the strength to hunt a bounty monster. As Ziwei, he kills a Blood Curse monster that has cornered a Monster Hunting Bureau squad, rescues a trapped schoolgirl, and leaves with the monster’s core. He keeps the identity secret and discovers that sustaining the transformation rapidly burns through his physical energy 1 3 4.

Su Bai later forms a working squad with Mint and Cherry. Although Ziwei becomes a celebrated public figure and the Bureau takes an interest in her, he continues attending university and concealing his magic. He buys secured manors to store monster-hunting spoils away from his shared apartment 11 14 27 31.

He guides Ye Qingqing through her awakening and gives her a harsh first combat lesson. When Xiaoxiao independently awakens as the Magical Girl Starshine, he accepts her into the Star Magical Girls and teaches her to protect her identity and retreat when necessary. He tells her that Ziwei is her brother, but she assumes he is joking 42 49 51 52.

Appearance

Su Bai’s ordinary appearance contrasts sharply with Ziwei’s elaborate magical form 1 2 4.

• Ordinary form: A lean, muscular young man, often seen in a worn hoodie, sweatpants, and inexpensive shoes 1 4.
• Ziwei form: A tall woman with waist-length violet-gold hair, pale skin, and a cool, mature voice 1 2 18.
• Magical outfit: Violet-gold armor, black lace and silk, and black stockings; its revealing design leaves Su Bai uncomfortable in cold weather 2 3.

Personality

Su Bai is disciplined, dry-humored, and intensely attentive to costs. He prices monster cores during emergencies, bargains over property, and keeps track of small savings even after acquiring substantial wealth 14 25 31 36.

He rejects the idea that he must save the entire world, defining his goal instead as protecting Xiaoxiao and their everyday life. In practice, he repeatedly puts himself in danger for civilians and teammates. He also guards his independence and privacy, refusing public attention and using plausible cover stories when the Bureau investigates him 10 20 26 27 54.

Abilities & Skills

Transformation and flight

Su Bai’s personal incantation transforms him into Ziwei and lets him fly, though he initially struggles to control his hovering and landing 1 2 3.

• The transformation produces conspicuous violet-gold light 1 4.
• Sustaining it consumes his own calories and leaves him ravenous and weak; his first transformation ends only when his energy runs out 4 40.
• Before his magic stabilizes, Kabi warns that transforming could cause a fatal explosion 10 11.

Scythe combat

Ziwei’s Dark Gold Giant Scythe combines exceptional cutting power with Su Bai’s direct fighting style 3 10.

• Kills an F-rank Blood Curse monster and an armored E-rank rhinoceros with single strikes 3 10.
• Can deliver distant strikes; one shatters reinforced sniper barriers and railings roughly 300 meters away 39 43.
• Dusk Calamity Annihilation charges magic along the blade for three breaths and seals energy in what it touches 32.

Magic and protection

• Uses small amounts of magic without transforming, contrary to Kabi’s understanding of Magical Girls 9.
• Compresses and conceals his magic well enough to evade a Bureau detector during an apartment search 26.
• Helps create a Starlight Barrier through resonance with other Magical Girls, containing a dangerous battle; later erects a barrier around the shopping district attacked by the Bloodthirsty Stitching Beast 14 18 49.
• Uses Twilight Coffin to seal attackers’ weapons and abyssal-energy devices, draining their magic while leaving them alive 39.
• Uses gravity magic and manipulation of magic circuits to stop three men targeting Xiaoxiao without transforming 45.

Physical training and mentoring

• Follows demanding workouts; before transforming, he lifts an 80-kilogram dumbbell, and later completes a 100-kilometer run 1 10.
• Guides Ye Qingqing’s wind magic into a Starwind Seed, enabling her awakening. The process draws on his essence and leaves him severely exhausted 42 43.
• Favors practical survival training: he has Ye fight two approaching monsters herself while he instructs her 41 42.

Equipment and Items

• Dark Gold Giant Scythe — Ziwei’s transformation weapon 1 3.
• Companion Magic Book — stores and unlocks techniques using absorbed energy and materials 32 36.

• Star Magical Girls communicator and terminal — used for team coordination and account records 14 29 31.
• Two secured hillside manors — purchased as a discreet base with protective fields, underground vaults, and teleportation access 30 31.

Relationships

• Su Xiaoxiao — Younger sister and organizer of Ziwei’s fan club. She eventually joins his team as Starshine but does not believe his claim that he is Ziwei 7 49 51 52.
• Kabi — Guardian spirit bound to Su Bai; provides warnings, combat guidance, and information about Magical Girls 9 10 35.
• Xia Ning / Mint — Xiaoxiao’s best friend and a member of Su Bai’s magical-girl squad 11 14.
• Lin Guoguo / Cherry — Trusted associate who sells cores for him and later joins the squad; she also helps support his alibi during a Bureau inquiry 6 14 40.
• Ye Qingqing — Magical Girl whose awakening Su Bai guides as Ziwei; she admires both Ziwei and Su Bai without knowing they are the same person 42 47 48.
• Liang Bing — Monster Hunting Bureau enforcer who repeatedly investigates Ziwei and questions Su Bai, but has not established their connection 27 35 45 46.
