A metallic life form that attached itself to a meteorite. In her original state, she resembles a large droplet of liquid metal. After coming into physical contact with Keiji, however, she adopts the form of a human girl by default. She can return to her ‘slime’ form if it’s just for a few minutes, and she can even shapeshift to imitate the things around her. Like a baby duck, R-ne imprints on Keiji the moment they meet, and is thereafter always by his side. She sits on his lap and sleeps next to him whenever she gets the chance. Able to develop communication skills in just a few days, she demonstrates a frightening capacity to learn. While she doesn’t feel “emotions” yet, they seem to show signs of awakening...

Her interactions with Keiji, Shino and the other townspeople have awakened in her the desire to return home to her friends in space. She has an extreme hatred of heat, and loves just about anything that's nice and cold. Baths, however, are a different matter altogether.
