Infinite Ryvius Vol1: Lost Ins DVD

It is now 2225AD and teenage cadets learn to navigate around this deadly obstacle at the Liebe Delta Astronaut Training Centre on the edge of the Geduld Sea. An act of sabotage during a routine dive procedure sends the space station plummeting into the Geduld. Juli Bahana, a member of the elite Zwei cadets, must take charge and lead the others to safety aboard the Ryvius, an interstellar space ship hidden inside the station. At the same time, navigator-in-training, Kouji Aiba, is coping with sibling rivalry while trying to find the courage to use his skills to deal with this deadly situation. Since all the adult crew and instructors were killed during the evacuation, the young astronauts can only rely on their training and each other to survive the journey home.
