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 an absolute masterpiece. It is easily one of the best anime ever made. It is the most underrated anime I have ever watched. It is quite insulting and saddening to see so many people consider such a Goliath of Creativity to be anything close to Mid. The Ryvius is practically the Dingdongmenship itself.

Yet even acknowledging all of this, I am still so confused why it is rated so low.

This show is essentially "Lord of the Flies" on a spaceship combined with mecha fights. Children are trapped on a spaceship, attempt to form their own civilization, and fend off unknown enemies for as long as they can. As time goes on, their morale breaks down, and their civilization begins to crumble.

This show has the pieces to make something special: characters, setting, animation, and story, but average execution affected the overall result.

There are themes of forgiveness, standing up for what you believe in, and redemption, but some characters often go way beyond delinquent into straight up evil. By the end, I thought some characters ...

I wish I could've liked this, really, I tried so hard to like this. The premise was kinda interesting and characters seeming had a story to them... But after 25 episodes of spiraling further and further into a pile of horse sh*t, the last episode did absolutely nothing in terms of conclusion. I've not much to say except don't bother with this. Not a single resolution you want to be made, is made. There is no fulfillment. Seriously. (As for specifics, spoilers below)

...Spoiler Warning...

The main character wasn't particularly bad. In all honesty there's a lot worse out there - take Future Diary's protagonist for example. ...
