Qubi

Biodata

Background

Qubi serves as Chen De's Contract Familiar following Chen's magical-girl contract. It identifies Chen's exceptional talent early: Chen manifests both a gun and a blade during the first transformation, indicating unusually high magical-power density and conversion efficiency 2.

It initially withholds major terms of the contract, including the gradual physical changes caused by magical power. When confronted, Qubi characterizes this omission as having “selectively forgot some of the terms” 3. It later assists Chen in managing the consequences of those changes, including arranging the transition to the identity of Su Xi and changing Chen's phone number 40 41.

Qubi is not unique. It explains that other magical girls possess similar Contract Familiars, though they may use different names for them; these familiars are separate terminals within one system and have differing permissions 19.

Its guidance extends to the informal institutions supporting magical girls. Qubi explains that headquarters was founded by veteran magical girls and operates with precarious finances, while jurisdiction rules were largely improvised by Contract Familiars to keep territories protected from Calamities 379 394.

Appearance

Qubi normally presents as a small, fluffy white cat with emerald-green eyes, a swishing tail, and ordinary feline paws 3 19.

• Its familiar form is invisible to ordinary people.
• Contractors and people with magical power can see it. 3
• It frequently rides on Chen's shoulder, head, or inside a backpack. 3 113
• Despite its feline appearance and behavior, Qubi rejects being called a cat. 74 91
• It can alter its size, shrinking to approximately half its usual size to ride more unobtrusively on Chen's shoulder. 8
• It also curls up on Chen's lap during quiet household moments. 394

Personality

Qubi is blunt, sarcastic, and intensely literal. It repeatedly describes cutting assessments as “objective facts,” whether criticizing Chen's habits, magical skill, or combat decisions 27 72 291. Its practical outlook often clashes with Chen's emotional reactions, producing frequent arguments.

It is also evasive with information when it considers disclosure unhelpful or premature. Qubi regulates Calamity notifications to prevent Chen from clearing too many targets and triggering stronger threats, and it refuses to provide some information until Chen can safely use it 20 33 88.

Beneath its detached manner, Qubi consistently monitors Chen's condition. It covers Chen with a blanket during Magic Overflow, wakes Chen for Calamity activity, and guides Chen toward safer training and combat decisions 65 108 190.

Qubi's teasing also has a connection to Chen's magical growth. During Magic Overflow, the narration links its repeated provocations to Chen's unusually strong emotional-growth multiplier, although Qubi would not admit this motive 65. Its psychological insight is particularly evident when it identifies Chen's desire to preserve an ordinary student life while seeking excitement and the feeling of being needed through magical-girl work 189.

Despite its confident manner, Qubi is not omniscient. It admits that it cannot explain why Chen draws on body-sustaining magic rather than reserves during one attack, and it cannot specify the number or appearance of possible future evolutionary stages 195 398.

Its pride coexists with vanity and self-preservation. It becomes jealous when Chen praises another cat, accepts Qin Luoyu's compliment, and quickly seeks protection when its companions throw or mishandle it 145 336. Although it frequently denies being a cat, it occasionally adopts that description when convenient 6 186 257.

Abilities & Skills

Calamity Intelligence and Threat Assessment

Qubi gathers and updates intelligence on Calamities, including their location, likely threat level, abilities, and hatching time.

• Updates the probability of a Fierce Calamity in real time. 3
• Detects nearby hostile presences and estimates their distance and speed. 12 133
• Identifies traits such as passive regeneration and estimates the force required to defeat a target. 90
• Tracks the relationship between rapid Calamity clearing and the likelihood of stronger Calamities appearing. 20 33
• Restricts or delays notifications when continuous clearing would create an unacceptable risk of spawning a Dire Calamity. 20
• Can predict weather changes through atmospheric-pressure sensing. 336
• Refines its assessments at closer range, explaining that approaching a Calamity can make its perception clearer. 100
• Identifies materialized malice that interferes with perception and suppresses magic during a Dire Calamity battle. 110
• Senses a faint trace of a weakening Lesser Calamity in a nearby alley and confirms that the residual pollution has been cleared after Chen destroys it. 406

Magical Training

Qubi trains Chen through an “orthodox route” centered on control, stability, and gradual Magic Formation construction.

• Teaches basic shaping of magical power into stable forms. 37
• Explains circles as the basic vessel for magic and geometric structures as the basis of Magic Formations. 38 42
• Guides Chen through Triangle Formations before later polygonal formations. 42 60
• Evaluates Chen's mental-energy limits and magical progress. 42 50
• Explains an alternate “direct enlightenment” method that imprints completed formations into a magical girl's consciousness. This method requires the Contract Familiar to view all of the magical girl's memories, which Chen refuses on privacy grounds. 60
• Explains that purified magical power is denser and harder to regulate precisely; an intended thirty-percent output may become fifty or seventy percent if control slips. 69
• Recommends A Hundred Skills Every Veteran Magical Girl Must Learn, while warning that technically simple skills such as Flash Grenade and Mana Shield may be dangerous or impractical with Chen's enormous output. 204
• Warns against borrowing another magical girl's weapon, since its consumption is calibrated to its owner's constitution and may exhaust a weaker user with a single attack. 271
• Advises Lin Xi to improve basic movement and attack accuracy rather than comparing herself directly with Su Xi. It explains that magical power grows mainly through time and emotion, with intense emotional fluctuations potentially producing sudden but uncertain increases. 388
• Describes Chen as being at “stage two and a half,” accumulating power toward another breakthrough, but offers no firm prediction of the eventual change. 398
• Suggests examining Qin Luoyu's weapon after her second-stage fusion, helping the group discover her upgraded longbow. 399

System and Logistical Support

Qubi acts as Chen's interface with the magical-girl system and its associated services.

• Introduces Chen to the Starwish Marketplace and explains materials such as Mithril, which reduces the magical cost of materialized armaments. 23
• Calculates rewards and platform-service deductions after Calamity elimination. 12
• Provides information on local magical-girl communications and system privacy protocols. 19
• Arranges identity-management options after Chen's physical changes make the original identity untenable. 40 41
• Explains the Holy Grail War's eligibility, team rules, combat conditions, and elimination criteria. 266 269
• Arranges a complete expedited background for Su Xi, including school admission, visa, airline, immigration, and transfer records, at a cost of 100,000 Magic Coins. 41
• Introduces the 3D Simulation Pod and explains the costs and limitations of separately purchased Calamity combat data. 88
• Explains the nationwide magical-girl merchandise platform and the absence of individual sales commissions. It states that the system has no legal-dispute channel but can arrange an application for psychological assistance. 102 103
• Exchanges messages with Qin Luoyu's familiar, Little Bell, using Chen's old phone, and relays information about the completion of the household renovation. 245 249
• Explains headquarters' funding sources, including Alice's stock trading, merchandise sales, and action against illegal businesses, as well as the possibility of delayed magical-girl payments. 379
• Explains that magical girls should normally remain within their jurisdictions, with exceptions for work, school, family circumstances, and familiar-approved special missions. Unauthorized travel may result in loss of access to Calamity information rather than severe punishment. 394

Lock Interference

Qubi can interfere with non-reinforced locks at short range.

• Opens ordinary keypad and keyhole locks using a pale-blue glow from its claws. 132 289
• States that all Contract Familiars possess this ability against locks without Mana Enhancement. 132
• Can open an ordinary lock in approximately three seconds. 116 289

Field Support

Qubi provides minor but useful support during missions.

• Produces intense illumination through its eyes when bribed with chicken drumsticks. 81
• Remains with Chen during missions to provide directions, warnings, and commentary. 3 191
• Can remain awake to monitor danger while exhausted magical girls rest. 133
• Describes itself as a support-role entity rather than a damage dealer. 3
• Watches over an unconscious Lin Xi while Chen and Qin Luoyu go out during the Holy Grail War, later observing their battle through Little Bell's live broadcast. 272 274
• Protects its own eyes before the enhanced Flash Grenade is fired into a Calamity's black fog and confirms that the revealed monster is still moving afterward. 384
• Demonstrates enough agility to evade Lin Xi's pursuit through several streets and perch on her head without being caught. 406

Power Progression

Qubi has no confirmed personal evolution or increase in power in the available account. Its progression consists of abilities and operational functions revealed over time, rather than the magical-girl advancements it supervises.

Relationships

• Chen De / Su Xi — Contractor and primary partner. Qubi trains Chen, manages information and logistics, and regularly argues with Chen over money, privacy, and risk assessment 3 37 40 60. It recognizes Chen's protective impulses beneath her denials and provides unusually direct psychological assessments of her motivations 189 378. Qin Luoyu interprets their mutual teasing and physical tussles as evidence of a good relationship, an observation both reject with matching disgust 394.
• Lin Xi / Xing Lan — Fellow magical girl whom Qubi assesses bluntly, advises during combat, and accompanies during group operations 90 117. It also serves as a reluctant navigator when left with Lin Xi, Fang Moying, and Luo Xiaoxiao 286. After Qubi explains emotion-based growth, Lin Xi spends half an hour trying to become stronger by getting angry at it, without success 388 389. Their antagonistic play continues when she unsuccessfully chases it through the streets 406.
• Xia Luo — Treats Qubi as an exceptionally pettable cat despite Qubi's objections; Qubi is visibly uncomfortable with being handled by her 77 216.
• Qin Luoyu — Initially earns Qubi's acceptance after Qin Luoyu compliments its appearance 145. After she catches it when Lin Xi throws it through the air, Qubi declares her its “primary guardian,” provoking Little Bell's objection 336. It later waits with Chen and Lin Xi during her fusion and suggests inspecting her transformed weapon 399.
• Little Bell — Qin Luoyu's electronic familiar. Qubi exchanges messages with it, discusses their contractors, and watches its live battle broadcast during the Holy Grail War 245 274. Little Bell objects when Qubi claims Qin Luoyu as its guardian, insisting that it is her only Contract Familiar 336.
• Mu Zhixue — A frequent target of Qubi's dry commentary during the mountain outing, especially concerning her weather manipulation and the absence of her cloud familiar, Yunduo 342 344.
• Other Contract Familiars — Separate terminals of the same underlying system, with varying permissions and operational styles 19 33. Qubi and Haitang sense each other's presence when their groups nearly cross paths during the Holy Grail War, but Qubi does not alert its companions 300.

Story Role / Major Arcs

• Chen's contract and rookie period — Qubi introduces Chen to magical-girl combat, explains the dangers of Calamities, and reveals the contract's physical side effects only after the fact 2 3.
• Calamity-hunting regulation — It reveals that it deliberately spaces Chen's assignments to reduce the chance of triggering stronger Calamities before Chen is ready 20.
• Identity transition — Qubi presents Chen with identity-management choices and facilitates the creation of Su Xi's new identity 40 41.
• Magic-training arc — It shifts Chen away from wasteful “basic attacks” and into systematic formation training, beginning with shaped magical power and circles 37 42.
• Magic Overflow and integration — Qubi identifies Chen's extraordinary tenfold magical growth, then explains the refinement that follows Chen's full integration as a magical girl 65 66.
• Dire Calamity operations — Qubi supports Chen's progression toward Dire-Calamity combat, offering threat assessments while helping coordinate team roles 109 190 191.
• Post-battle diagnosis — After Chen's Dire Calamity victory leaves her exhausted, Qubi identifies that the attack drew on magic sustaining her body rather than her full reserves. It cannot explain the cause and recommends further practice 193 195.
• Holy Grail War — It announces the rookie tournament, explains its risks, and supplies temporary monitoring wristbands when Lin Xi arrives without her own Contract Familiar 266 269. The wristbands are rushed out overnight by Little Bell, as Qubi explains 269. Qubi also supervises the exhausted Lin Xi and later helps open Fang Moying and Luo Xiaoxiao's locked lodging 272 289.
• Headquarters recruitment — Qubi prevents headquarters from contacting Su Xi immediately, then declines the offer on Chen's behalf to buy time for a decision 366 368.
• Pacific incident and headquarters finances — When the group discusses missing ships and strange sea fog, Qubi says others are handling the matter and discourages Lin Xi from becoming involved prematurely. It subsequently answers Chen's late-night questions about headquarters' informal organization and financial instability 378 379.
• Renewed Dire Calamity encounter — Qubi accompanies the group during the black-fog investigation, assesses the monster revealed by their excessive Flash Grenade, and later gives Lin Xi practical advice about improving her combat performance 384 388.
• Jurisdiction explanation — Lu Qingqing's wish to visit prompts Qubi to explain territorial responsibilities, travel exceptions, and the loosely enforced rules created by Contract Familiars 394.
• Qin Luoyu's second-stage fusion — Qubi comments on the negligible energy lost through her glow, acknowledges uncertainty about further evolutionary stages, and directs attention to her newly transformed longbow once she awakens 398 399.
• Daytime patrol and household outings — Qubi detects a weakening Lesser Calamity during a street outing, verifies its complete cleansing, and continues accompanying the group through patrol banter and ordinary social plans 406 407 411.
