Personality

Mei is deeply devoted to Kiana and repeatedly measures her own worth by whether she can protect her. Her failures in Sky City leave her overwhelmed by regret and self-loathing, but also drive her into relentless training rather than resignation. 24 25 40

She is determined and self-sacrificing, willing to confront opponents far beyond her strength for Kiana’s sake. This devotion can become possessive and emotionally painful when she believes Kiana may choose others over her, but she ultimately honors Kiana’s wishes even when doing so hurts her. 42 43 46

Abilities & Skills

Story Role / Major Arcs

Search for Kiana in Sky City

Mei joins Theresa and Bronya in leaving Anti-Entropy to find Kiana. Investigating Gray Serpent’s hideout, she identifies Rita through a camera image and chooses to scout the S-rank Valkyrie alone. 14 22

Mei ambushes Rita with her katana and Crimson Impulse Armor. She lands a hit, but the encounter makes the gap between an A-rank and S-rank Valkyrie unmistakable; she is exhausted and later captured by Su Jue. 22 23 24

Resolve Born from Defeat

While held hostage, Mei notices Kiana’s star hairpin on Su Jue and refuses to stop seeking information about Kiana despite her injuries. Su Jue confronts her with her weakness, telling her that protecting, avenging, or reclaiming anything requires the resolve to sacrifice what she has. 24

Before leaving Sky City, Mei promises Kiana that she will return with enough power to protect her. She subsequently remains behind to train, cuts her hair, and develops her swordsmanship and use of the Striker battlesuit. 25 40

Reunion and the Honkai Bomb Crisis

Mei reunites with Kiana during the Sky City crisis. Though Kiana initially refuses to return to the Hyperion, Mei accepts her decision and accompanies her in searching for the Honkai Bomb. 42

When Kiana asks Mei to save Su Jue while she goes to the signal tower, Mei agrees despite the emotional strain of Kiana calling him important. She is later contacted by the Kiana Organization, which demands that she bring Kiana back safely. 43

Battle against Durandal

Mei tries to stop Durandal from capturing Kiana, driving the Striker battlesuit beyond safe limits. Durandal withstands Mei’s assault and defeats her, proving that Mei’s resolve alone cannot erase the difference in their strength. 46

Escape from Sky City and Kiana Organization Membership

Mei escapes Sky City with Kiana aboard Tread Snow and Benares. Even while injured and outmatched by pursuing Valkyries, she continues defending Kiana until Kiana uses spatial powers to destroy the pursuit. 49

After the battle, Mei watches over Kiana in hiding and uses the Kiana Organization’s inhibitor sheets to reduce Kiana’s Honkai erosion. Learning of the organization’s supposed casualties—including Griseo—Mei resolves to bear Kiana’s sacrifices herself and accepts her role as an Attendant. 49 50
