Rinna is a transfer student from the Ultima foundation, and considers Shipon to be both a friend and chief rival. Rinna is a few years younger than Shipon and most of the other students, but because there are few children at Ultima (it being the newest of the foundations, and still incomplete), she has little to do with herself but play with simulators.     As a result, she&#039;s far better at piloting and zero-G movement than most people years older than her.   (Wikipedia)

To keep track on all space activities, mankind has built colossal space stations called "foundations" all over the Solar System. After passing the Space Academy entrance exams, Shima Katase embarks to the Earth-based foundation Stellvia to fulfill her dream of seeing the galaxy and to prevent another interstellar catastrophe from destroying Earth.

A Japanese voice actor. She's also a certified junior and senior high school teacher.

Hirohashi was born in Niigata Prefecture, and her family's home was a Buddhist temple. Because of this, she attended Ryukoku University in Kyoto, a Buddhist university. In the middle of her first year, however, her parents told her that she could do what she liked, even if it wasn't related to Buddhism, so she sought out what she wanted to do. During her second year, she remembered a radio show she used to listen to in middle school and became interested in voice acting, so she started going to the Aoni Coaching School Osaka while attending university at the same time. The radio personality she had listened to in junior high school was a voice actor, which inspired her to become a voice actor herself.
