Background and History
Mei enters the Imaginary Tree seeking answers about Honkai and Herrschers. There, she investigates MOTH's memories and the history surrounding Lin, repeatedly challenging the explanations offered by its inhabitants 1 33 116 123. Her encounters with Lin range from battles to an uneasy exchange of information; after defeating him in one fight, she receives an imprint from him but remains suspicious of the gift 76 77 78.
In Sky City, Mei makes a guarded deal with Rita: she will obtain an antidote in exchange for Kiana's whereabouts. She infiltrates Shencheng Pharmaceuticals and retrieves it, but continues to distrust Rita 613 614 617. Later, Mei becomes the Herrscher of Thunder again and joins World Serpent to keep Kevin from acting against Kiana 656 724.
After the Great Honkai, Mei remains on the front lines, clearing its remnants. She becomes a captain in one of the reorganized Schicksal squads 779.
