Background / History

The Third Great Honkai ended Mei's high-school life and led her to join Moth of the Fire. She became the organization's indispensable scientific generalist: while specialists such as Mobius and Verne surpassed her in particular fields, Mei could work competently across disciplines and lead large research teams effectively. Her political ability was comparatively limited, but she became the figure willing to shoulder responsibility when the Flame-Chasers' faction needed a public face. 284 285

Her work advanced major anti-Honkai initiatives, including Fusion Warrior surgery, Divine Keys, and Stigmata research. Later accounts describe her as the leader of Moth of the Fire and head of the Thirteen Flame-Chasers. 352

Little Griseo's arrival confronts Mei with the future consequences of her work. In the original course of events, Mei used the prototype Key of Blank to eliminate the Thousand-Man Herrscher, but the strain damaged her health and contributed to her premature death. 41 Rather than reject the warning, she works with Little Griseo to alter the civilization's fate, preparing survival plans before the Herrschers' later descent. 64

Appearance

Mei has Yae's face and normally wears glasses while working. Even before marriage, Little Griseo considers her appearance that of a composed married woman rather than an ordinary young researcher. 36

• Wears glasses. 36
• Carries a calm, scholarly demeanor distinct from Mobius's fanaticism and Verne's eccentricity. 185
• Is physically frail despite qualifying for the Herrscher Project; prolonged walking can leave her out of breath. 1131

Personality

Mei is intensely rational, pragmatic, and willing to make decisions that condemn others to hardship if they are necessary for survival. She recognizes her own sins and does not attempt to excuse them; in her view, reality forced her to become the person who can calculate costs and make cruel choices. 82 86

This restraint conceals strong emotions. Mei consciously protects Little Griseo's innocence, preferring that adults like herself bear the moral burden rather than force Griseo to become equally calculating. 82 86 Her pragmatism is tempered by a consistent priority for human survival: she favors relocating Mu Continent survivors over preserving material assets and seeks negotiation before coercion. 69

Although she can command scientists and soldiers, Mei does not enjoy public management. She is uncomfortable facing billions of people and is described as socially anxious, yet accepts the role of Moth of the Fire's spokesperson when necessary. 183

Abilities & Skills

Scientific Expertise

Mei is an all-round scientific prodigy capable of contributing across numerous disciplines rather than remaining confined to one specialty. 284

• Advanced Fusion Warrior, Divine Key, and Stigmata projects under her leadership. 352
• Conducted and coordinated the extensive testing used to verify Little Griseo's identity. 33 34 36
• Collaborated with Mobius on research into souls, matter, and consciousness. 550
• Her exceptional intelligence comes at the expense of physical stamina. 1131

Strategic Planning

Mei specializes in turning information and scarce resources into workable survival plans.

• Worked with Little Griseo, who supplied a high-dimensional overview, to plan for the coming Herrscher crises. 64
• Proposed removing the Mu Continent from the timeline's active management while relocating survivors to the next era and negotiating new identities for important figures. 69
• Planned Shelter expansion around scientists, useful personnel, and their families to preserve humanity after Finality. 87
• Adapted the captive-management plan by having Moth of the Fire personnel covertly influence public opinion. 175

Administration and Public Leadership

Mei became the primary administrator and public representative of the Ark's Moth of the Fire faction.

• Helped manage the relocation and settlement of nearly three billion people from a collapsing civilization. 187 208
• Used broadcasts to communicate directly with the Ark's population instead of dispersing personnel among millions of separate groups. 182 183
• Delivered frank public disclosures about Honkai, the incurable Honkai disease, and the projected arrival of Finality. 188 189 190 191
• Worked with other administrators to formalize the Contribution Point system, seeking Little Griseo's approval so its rules would carry legitimacy. 245

Equipment / Items

• Prototype Key of Blank — In the original future, Mei wore this prototype to defeat the Thousand-Man Herrscher; the exertion severely harmed her health. 41

Relationships

• Kevin — Her partner and later husband. Their relationship develops from a restrained bond into marriage, parenthood, and a shared commitment to protect their child. 247 287 384
• Eve — Mei and Kevin's daughter. Mei uses Contribution Points to secure Eve's potential and well-being before her birth, while remaining concerned that excessive talent could burden her childhood. 384 386 543
• Little Griseo — Strategic collaborator and trusted superior on the Ark. Mei values Griseo's innocence, handles difficult decisions on her behalf, and regularly consults her over major reforms. 64 82 245
• Mobius — Fellow scientist and collaborator. Mei recognizes Mobius's unmatched life-science expertise, while Mobius defers public representation to Mei because of her own poor reputation. 284 183 550
• Su — Close friend and assistant who takes over Mei's regular reports to Little Griseo while she prepares to start a family. 247 252
• Cosmos — A younger companion whom Mei increasingly treats like a son after becoming a mother; she encourages his relationship with Desdrobia. 544

Story Role / Major Arcs

Little Griseo's Identity Investigation

Mei leads the decision to move Little Griseo's verification into the laboratories, prioritizing DNA and medical evidence over speculation. She remains focused on the tests even while her normal workload is delayed. 33 34 36

Future-Honkai Preparations

After accepting Little Griseo's testimony, Mei confronts the future threat of the Thousand-Man Herrscher, the Herrscher of Binding, and later Herrschers. She helps convert Griseo's future knowledge into practical survival strategy rather than treating it as mere prophecy. 41 64

Mu Continent and Shelter Project

Mei prioritizes lives over territorial or material preservation, arranging for Mu survivors to be relocated rather than abandoned. She also directs the secretive Shelter Project, accepting harsh selection and labor decisions as the cost of preventing extinction. 69 71 86 87

Ark Resettlement

When nearly three billion people are brought onto the Ark, Mei becomes Moth of the Fire's reluctant spokesperson. Her broadcasts explain the Honkai disaster, the impossibility of curing Honkai disease, humanity's impending defeat by Finality, and the Ark's proposed refuge. 183 188 190 194

Ark Administration

Mei and her team establish the Ark's administrative sector, organizing familiar regional settlements and a teleportation network between cities. She later helps establish more consistent Contribution Point rules instead of allowing the system to depend entirely on Little Griseo's preferences. 208 245

Family Life

With the Honkai crisis averted for her branch of history, Mei chooses to build a family with Kevin. They prepare for Eve's birth, use their resources to improve her future prospects, and later raise her together. 247 383 384 543
