Haruka

Haruka is a thirteen-year-old girl who was, at first, the sole known human survivor on Earth. During the final war, her parents placed her in a cold sleep chamber, sacrificing themselves to help the machine reach the required temperature. She remained in the machine for thirty years before her robot family discovered her a year prior to the series' timeline. She maintains a very positive outlook and is hardworking. She loves all the robots and regards them as her family. In the anime series, she is voiced by Yui Horie.
