Here is Serval’s profile, via the Honkai: Star Rail official website:
The free and rebellious eldest daughter of the Landau family, once a close friend of Cocolia, her interests has now led her to become a mechanic.
In the perpetually winter-stricken Belobog, she opened a workshop called “Neverwinter” that puts business on hold from time to time for rock ‘n’ roll performances.
And should anyone ask her about the workshop’s profitability…
“This is just a hobby, dear. I’m not short of money.”
Honkai: Star Rail is in development for PC, iOS, and Android. A second closed beta test is ongoing.
