In the future, a solar flare called the Geduld Phenomenon spreads a vast, chaotic plasma field across the solar system, killing many but ironically bolstering humanity's drive to colonize space. Many years later, the Liebe Delta astronaut training center is established to educate teenagers in practices such as piloting, nursing and stewardship. But the center, which conceals a prototype battleship called the Black Ryvius, is sabotaged by an unknown party, and the remaining adult instructors sacrifice themselves to save the station from plunging dangerously into the Geduld field. Meanwhile, the station's 400-plus students discover the hidden battleship and are forced to remain aboard it, protecting themselves and governing the student body as best they can while searching for salvation.

"Lord of the Flies" meets "Lost In Space"
28 March 2005 | by PerdicusSee all my reviews

It is the year 2225 A.D., and the solar system has become a much more dangerous place as a result of the "Gedoult" phenomenon, a natural disaster which has made interplanetary travel extremely hazardous. A group of roughly 400 teenagers boards the Libe Delta Astronaut Training Center, in orbit around the Earth. But the Libe Delta is hiding a deadly secret, and the students are swept up in a storm of sabotage and treachery.

Forced to abandon the Libe Delta, they find themselves aboard the "Ryvius", the most advanced warship ever built, hidden within the core of the station itself. Now this intrepid group of young space explorers must face the ultimate challenge: survival.

* * *

"Mugen no Ryvius" (or "Infinite Ryvius", if you will) is a brilliant, underrated piece of animation from TV Tokyo and Sunrise, Inc. A group of unruly (albeit highly educated) teenagers is set loose on a super-powerful warship with no adult supervision, and the ship's creators aren't helping any. "Lord of the Flies" meets "Lost In Space", indeed! Great music, a terrific ensemble cast, and plenty of action. My rating: 8/10 (points off for overuse of teenage angst).
