Mamoru smiled, a small, tired curve of his mouth. His family thought he worked as a night security guard. They didn’t know about the ball bearings, the nerve strikes, the Ministry handlers who called him “Kage” and treated him like a tool.

She is a martial arts prodigy in her own right (the Konnyaku family runs a dojo), but her luck is so catastrophically bad that her skills can never save her from the timing of the disaster.
