What happens when authority and consequence are removed? When the inmates truly run the asylum. On the spaceship Ryvius there are those who would fight for order, and many more who would fight to destroy it. Love, hate, anger, greed, avarice, and perhaps hope are the fuel for the Ryvius, and only one can save those who call it home...
It is the year 2356 AD, 189 years after a shockwave from a distant supernova decimated the Earth. Since that fateful day, humanity has begun training for a final mission to protect the planet from the inevitable oncoming 2nd shockwave - a mission whose failure means the annihilation of mankind. For Katase and her friends, their training at the foundation Stellvia is just the beginning of an adventure that could lead to saving the world, or seeing its end...
Stellvia and Infinite Ryvius just seem to have the same kind of feel, though admittedly, Stellvia is MUCH more light hearted than IR. One major thing that I think both have is a lot of character development. Both of these series got criticism by some people for being too slow at times and focusing too much on character development, which I personally think is a good thing. Anyways, I'm not sure how to explain exactly why I think you'd like one if you liked the other, so just trust me on this one. ;)
Both Stellvia and Ryvius have characters that are put through "tough" situations. They are also both sci-fi themed and have the same sort of feel, although Ryvius is much more harsh. I believe that both are great shows and if you liked one you would like the other.
In the year 2075, humanity has spread to the stars, along with their technology, colonies, and... waste? At such great speeds in orbit, even a tiny bolt can cause a tragic disaster. Enter the team of the half division. Their job? To gather the garbage and debris that circles the Earth, in order to keep space safe. From broken-down satellites to bolts and nails, there's nothing that the underpaid and underappreciated staff can't salvage. Join Hachimaki, Tanabe, Fee, and the rest of the gang as they risk their lives to keep space clean, and keep their wallets... empty.
Both Planetes and Infinite Ryvius have a general "realistic" sci-fi theme as well as characters who are forced to cope and deal with new issues in their lives. While Ryvius is a little "darker" than Planetes, Planetes still deals with some heavy topics such as someone close to you dying. They both also have good character development. Overall, I think that if you liked Planetes or Infinite Ryvius you would probably like the other.
Both of these show are similar in alot of ways. what really struck me the most was how both shows were slow to build up and sort of slice of life, but go out with a bang. if you like the character drama in one then the other is similarly well done, though planetes was clearly more polished.
Luna is an orphaned girl with dreams to attend a prestigious academy. After her celebrated acceptance, the class embarks on a field trip to see a world being colonized first-hand. However, in the middle of the journey, a storm overtakes the space vessel, causing a pod with Luna and a small group of students to be jettisoned into a gravity well -- stranding them on a planet far from home. Now, with monsters at every turn and supplies running short, the group of strangers must do the only thing they can -- survive.
While the tone of these two series is far different (IR being very serious/dark, UPS being a slightly lighter tone with an adventure type feel), they both present a similar dilemma -- a set of youths who are lost, and have to fend for themselves. Both also have issues involving getting along, and getting things done in order to survive. Plus, both are really good shows in general.
Both UPS (Uninhabited Planet Survive for short) and Infinite Ryvius deal with youths being forced into a situation where they are in charge of everything including their lives, and the only way they can survive is to rely on each other. While UPS is much more "light" than Ryvius I think if you liked one you have a good chance of liking the other.
Tada is a young man on the fast track to the Cosmo Academy -- a school which only accepts applicants every three years, and whose entrance rate is under 1%. Having passed all the prior exams, the final test is drawing near: survive for 53 days aboard a derelict spaceship with only 9 other would-be cadets to assist you. But much to the dismay of Tada and his peers, their ship has acquired an eleventh member! Can the crew band together to survive the test? Or will sabotage simply destroy them from within...
Both series show how people that find themselves stuck together deal with dangerous situations when they appear. Infinite Ryvius is more elaborate and goes deeper down the emotions ladder while They Were Eleven has more of a analytical feel to it.
They Were Eleven and Infinite Ryvius feature the same kind of themes: a bunch of people stuck in narrow space. This takes its toll on the characters, especially psychologically, and the true essence of their personalities surfaces. Who will handle the pressure and stay calm? Who will freak out, who will go insane? People change as the genetical instincts slowly but surely grow stronger within them. Both series depict this change very well. That, and how different leadership doctrines lead to very different outcomes.
Infinite Ryvius and They Were Eleven definitely have similar plot points, as well as a high level of angst and tension you could cut with a knife. Very interesting stories that will enthrall your attention. I highly think if you liked one, you'd like the other.
