When you began your course at UA, it was you among many others in the hero course that showed great potential. You had a quirk to be reckoned with, your strength and control were ideal, and your mental strength was admirable. So why? Why did you leave? Somehow, after two short years of attending UA something changed, and you were gone like the passing summer breeze, never to be seen again, or so they thought.
They happened to encounter you once again years later, when they were all Pro Heroes and famous role models. It was meant to be a happy night for them all, a social gathering, kind of like a reunion, hosted at the City Hall. A few of them snuck out into the rooftop together to wind down, to relax without having to converse with bustling reporters, when they caught a glimpse of you. At least they thought it was you.
