The year is AD 2225. Kouji Aiba and Aoi Housen are serving as astronauts in-training in Liebe Delta which is located on the edge of the Geduld Sea. When saboteurs with unknown intents suddenly strike during a routine dive procedure, the space station plummets into the Geduld, a plasma field that links all the planets like a nervous system and crushes any ship that strays too far into it. With all the adults onboard killed, the young astronauts will have to survive this long journey home in midst of the growing tension amongst each other. Meanwhile the organizers of the sabotage look on and prepare to attack once more.


The series won the Television Award in the 5th Animation Kobe Awards in 2000.

Infinite Ryvius is essentially "Lord of the Flies" on a spaceship, although with students old enough to be in high school (surprise, surprise). Once the students are stranded without their teachers, in various hostile situations, the anime becomes a microcosm for the problem of governance. We have the authoritarians, we have the democrats, and everyone in-between. Most striking for me, about this series, was the slow descent from happy-go-lucky "let's try our best at being space heroes" to chaos, mob-rule, and abuse of power. Having gone to teachers college, I'd hazard that many students would do well to watch this anime, ...

Mixed Feelings
The artistic presentation is definitely not the selling point of Infinite Ryvius. I'll state one of my major complaints with the show right off the bat: It is permeated by numerous elements that feel tenuously connected to the setting and the plot, and while the character designs aren't the worst offenders, they're a good visual representation of the problem. I can get behind the generic-but-acceptable “everyday kid” look of some cast members, and the spiffy flight uniforms worn by the group of elite pilots look halfway believable, but that's about as far as these designs could take me. It's hard to feel any sort of ...

I think I decided to watch this show based on finding several reviews that praised Infinite Ryvius. I thought -- I love scifi and psychological deterioration. Too bad Infinite Ryvius can't pull it off.

First, the basics. The art is standard 90's fair. The music is an interesting, if somewhat incongruous, choice. Neither really make or break the show.

The plot of IR is also interesting, but it never really pays off. For 20-some episodes, I waited for something really thrilling to happen. There was very little that was thrilling, despite regular space battles and general in-fighting. The few good moments were only as good as ...
