Hiroko Ai is the youngest of the Ares' crew at a mere thirty one. She is a prodigy of biosphere design, and is an expert at ecological systems development, biology, and agriculture. Hiroko has her own agenda on Mars from the very beginning, as she smuggles Desmond Hawkins onto the ship. Hiroko and her team are closely knit from the beginning, and it is eventually revealed that she and her companions have formed a religion know as areophany. Areophany is the concept that there is a union between the power of the colonists of Mars, or virititas, and kami, or the spiritual energy of the planet. This religious belief leads the team, led by Hiroko, to escape the first settlement and build a life for themselves in the chaos of Mars, creating new laws, and a utopia community. Hiroko uses the eggs and sperm of the first hundred to artificially create a host of children, and some of these children are a part of the destructive revolution.
