A bright and cheerful woman, Usagi is the kind of person who has little to no filter on her mouth. She’s perfectly capable of keeping secrets and being responsible, it’s just the little things that slip out; strange questions and twisty turny logic that sometimes (most times) leads to absolutely nowhere. She’s been this way her whole life and has never really seen a need to stop, not even after her “life changing event”.
Up until said event, Usagi was your average Japanese teenager. She hung out with her friends, read manga, played video games, and struggled with school. There are times when she looks at her life “before” and can only shake her head— she was so much the shoujo heroine stereotype that it shouldn’t have come as a surprise when she stumbled right into becoming one.
At fourteen years old Usagi found an old locket decorated to look like the moon, and thought it pretty enough to hold onto. When she opened it up she found a beautiful stone about the size of her thumbnail, and promptly (accidentally) bound herself to an ancient alien artifact. On the upside it was designed to amplify already existing powers. On the downside Usagi hadn’t known she was a mutant until the moment when the binding activated her powers.
For the first few weeks after getting the boost, Usagi kept it to herself and tried to pretend she hadn’t done anything. It wasn’t until an accident left her father bedridden, and she instinctively knew where and why he was injured that she realized that something had seriously changed. More so that she could do something about it: injuries were tangled knots of threads to her and with her powers tingling in the tips of her fingers she could touch them. Furthermore she could untangle them and in doing so heal the person in question.
Soon thereafter she began sneaking out and trying to heal as many people in hospitals and care centers as she could; it took time and a lot of concentration, but it was work that she was proud of. She was making a difference.
It was by pure accident that one of the people she was healing turned out to be an undercover S.H.I.E.L.D. agent. The agent would eventually manage to recruit her with the promise of getting her schooling as a nurse or doctor, whichever she prefered, and off she went.
She laughs at herself now for being so naive; she was trained as a field agent with the intention of going out there and healing agents on duty. Somewhere along the way she became one of those agents on duty, and fourteen years after her inital introduction to S.H.I.E.L.D. she wouldn’t have it any other way.
