Mizuki was an ideal climbing partner. I was lucky enough to climb with her every season for the past 5 or so years. She was extremely strong as a climber but at the same time very easy to get along with, very accomodating, and respectful of everyone.
Our running joke together was that every time we climbed we always accidentally went home with the other's gear, which required a follow-up meeting to exchange gear. More often than not she would volunteer to come by my work to perform the transfer - always laughing because it never failed that we went home with the other's gear - it was just the kind of person she was.
