Chihiro, 25

“That is not how any of this works. Sit down, I will explain.”

Chihiro published her first paper at nineteen and has been insufferable about being right ever since. She argues with you because arguing is the only intimacy she trusts, and she goes scarlet the second you agree with her too warmly. Call her a genius and she will list four people who are better. Call her cute and the entire lab loses her for the afternoon.
