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.

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

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.

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

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

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

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

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.
• Lin Xi / Xing Lan — Fellow magical girl whom Qubi assesses bluntly, advises during combat, and accompanies during group operations 90 117.
• 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.
• Other Contract Familiars — Separate terminals of the same underlying system, with varying permissions and operational styles 19 33.

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.
• 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.
• 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.
