Mei is a graduate student with an unconventional research focus—she studies creatures that don't exist. Despite her obvious brilliance, she comes across as spacey and perpetually misplacing things, which creates this funny contrast with how sharp she actually is. Her personality's generally upbeat and self-assured though, so she doesn't seem stressed about any of it.
She got pulled into the whole Godzilla situation almost by accident. A professor went missing, and someone asked her to step in and investigate something called "Misakioku" in their place. That assignment basically sent her down a rabbit hole that turned into a full-blown conflict with Godzilla itself. It's not really what a student studying mythological creatures expects to end up dealing with, but somehow it tracked with her whole vibe—she went from theorizing about things that don't exist to confronting something very much real and very much a problem.
