Now giving back to the community, NekoYasha talks about fun ways to use spandex and stretch fabric, uplifting the black cosplay community, and giving insights to how cosplay completions work. When not cosplaying, you can find them geeking out over wrestling, king of the hill and talk your ear off about the Type-Moon universe.
