Infinite Ryvius

Infinite Ryvius is an original sci-fi anime series that aired from 1999 to 2000.

Set in the year 2225 where space travel has become commonplace, Kouji Aiba is a teenager who leaves Earth to train as an astronaut at the space station Liebe Delta with his friend Aoi. However, saboteurs strike the station during a routine procedure, causing the station to plummet into a plasma field and kill all adults onboard. With the teenagers now stranded and forsaken, Kouji tries to maintain order and piece while they attempt to make their way home by themselves.
