Background / History

Mobius is a genetic-engineering scholar within the Flame-Chasers whose research centers on evolution, Honkai adaptation, and the modification of life. Before Byakuya joined her laboratory, she provided life-extension technology to wealthy elderly clients to offset her growing research costs; this practice and the expense of her projects drew opposition from Flame-Chasers higher-ups. 59

Byakuya deliberately transferred into her laboratory despite her reputation, arguing that life’s evolution had never been smooth. His confidence and willingness to be researched intrigued Mobius, who accepted him as an employee and began treating him as a live research subject. 52 53

Appearance

Mobius is usually seen in a white laboratory coat and is noted for her emerald eyes. 52 65

• Her casual clothing includes a green shirt worn beneath her lab coat. 92
• Following an unspecified incident, she appears in a smaller, more snake-like form that drips blackish-green fluid. 92
• Her Fusion Warrior physiology and Stigmata allow her to alter her body’s size. 101

Personality

Mobius is driven by an uncompromising fascination with evolution. She treats dangerous research as a necessary means to obtain results and has few conventional moral reservations, including indifference toward the fate of hostile pursuers when they threaten her laboratory. 58 59

She is sharp, teasing, and possessive in her interactions with Byakuya, habitually calling him “Little White Mouse.” Her affection does not displace her priorities: even after their relationship becomes romantic, she continues to place research first. 53 60

Despite her detached reputation, Mobius can be considerate toward people she values. She supports Byakuya’s choices after confirming his resolve, shows greater warmth toward Klein, and accepts responsibility for preparations against future Honkai threats. 65 67 104

Abilities & Skills

Genetic Engineering

Mobius is a specialist in altering, preserving, and evolving biological life.

• Develops lifespan-extension technology for wealthy clients. 59
• Conducts gene-fusion and Fusion Warrior experiments, including work on Honkai Beast integration and Artificial Collapse. 58 67 86
• Participates in Stigmata research alongside Doctor Mei and Byakuya. 101 102
• Successfully revives Gray Serpent despite more than 80% of its organic matter having corroded, then provides it with a mechanical body. 108

Honkai Research

Mobius researches methods to resist, harness, and adapt to Honkai Energy.

• Investigates Byakuya’s Quantum power and seeks to develop its traits. 54
• Produces a Honkai Inhibitor capable of suppressing Honkai erosion to a limited extent. 65
• Analyzes Honkai Beast tissue, gene fragments, and Herrscher-related samples for evolutionary research. 58 87 90
• Helps assess the results of Fusion Warrior transformations and Artificial Collapse experiments. 68 86 87

Fusion Warrior Physiology

As a Fusion Warrior with a Stigmata, Mobius possesses altered biology beyond that of an ordinary human. 104

• Can reduce her body to a smaller form. 101
• Maintains enough energy for prolonged, intensive research work. 104

Research & Creations

• Honkai Inhibitor — A green reagent developed as a research byproduct; it can partially suppress Honkai erosion. 65
• Fusion Warrior Project — A major and resource-intensive program to fuse humans with Honkai-related traits and improve their ability to resist Honkai. 58 67 89
• Gray Serpent — Revived by Mobius after catastrophic organic corrosion and fitted with a mechanical body. 108
• Stigmata Project — A project Mobius continues alongside other contingency plans for civilization’s survival. 107

Relationships

• Byakuya — Her employee, experimental subject, research partner, and lover. Mobius accepts his request for increasingly aggressive experiments after confirming his willingness, and their relationship becomes romantic after they confess their feelings. 52 60
• Klein — Mobius’s overworked laboratory assistant. Mobius relies on Klein for data collection and laboratory operations, later showing her more overt consideration. 52 67
• Verne — A fellow researcher and rival. Their first documented meeting is openly hostile, with both probing the other’s intentions and reputation. 70 71
• Bronya — Byakuya’s other half and a valuable research subject. Mobius records and examines Bronya’s successful fusion data and investigates her ability to control her physical age. 82 84
• Doctor Mei — A fellow Flame-Chasers researcher who collaborates with Mobius on projects including Fusion Warrior experimentation, Stigmata research, and preparations against the Herrschers. 86 101 109
• Gray Serpent — A life form Mobius successfully revives and reconstructs. 108

Story Role / Major Arcs

Recruitment of Byakuya

Mobius accepts Byakuya into her laboratory after he seeks her out specifically, dismissing outside rumors in favor of his own assessment of her. She begins examining his unusual Quantum traits and records his physical data. 52 54 58

Honkai Adaptation and Fusion Research

Mobius works with Byakuya on Honkai Beast gene fusion, warning him of its low success rate while remaining intrigued by its evolutionary potential. She oversees tests that improve his strength, speed, defense, Honkai adaptability, and eventually his Artificial Collapse stability. 58 68 86 87

Securing the Laboratory

Facing reductions in funding, Mobius attends a symposium and uses the laboratory’s Honkai Inhibitor research to secure a substantial allocation of resources. 59 67

Flame-Chasers Contingency Work

As the Honkai threat escalates, Mobius supports Fusion Warrior development, Stigmata research, the Seed Project, and the Ark Project. She also successfully revives Gray Serpent, viewing its survival-driven evolution as a profound success. 107 108
