Mugen no Ryvius

I've been passing this recommendation around in my head for a while and I figured why not put it out there. The similarities might not hit you right off the back, they are structured completely differently, Bokurano is based around small arc for each of the pilots, while Infinite Ryvius focuses on the whole plot, but once you get underneath, they both are very similar. Both shows present a large cast of unique children placed in a perilous situation against their will or better judgment. But mainly they share the same themes, responsibility, loss of innocence, power, and politics. You get many different ideas on each topic, which is very nice because I can't think of any of the hundreds of characters in either series that are similar. On an interesting note, you can overlay the music for one on to the other one's OP and they sync pretty well. read more 

Same artist, and a lot of the same characters, but in their own different universes. The animation also feels the same, so if you enjoyed one, i'm sure you'll enjoy the other. 

Another sci-fi story set in a futuristic society. Students aboard a ship end up having to assume control of it, and although there are some different spins on it, there are staggering amounts of similarities. I think if you enjoy one you'll enjoy the other. Because it is a longer series than Starship Operators they take the time to deal with the nitty gritty like food and water problems and other aspects of life that would be difficult to organize on your own with a bunch of amateurs.  

Almost identical premises - a group of teens are trapped on a spaceship miles away from any hope of rescue, and must figure out how to survive together. Astra is far more lighthearted than Ryvius, though it does have its moments of seriousness. 

Both are Sunrise anime about teenagers floating in space while defending off attacks from outside forces with their mecha. Both deal heavily with the personal relationships of the teenagers involved while they "struggle" to survive in the hostile environment. 

A bunch teenagers being thrown onto a mysterious space ship, and they found out their way surviving. Trust, betrayal, friendship, angst shown under various situations. They were 11 deals only with internal conflicts, being a 90 min movie a lot development has to be cut short. Also rewatchability is a bit low when you get spoiled at the end resolution. Infinite Ryvius being a 26 episode TV series, has a lot of time to develop its plot, and characters, despite the casts are huge. Teens in this series have to deal with outsider attacking and internal conflicts, so the story seems fuller than They were 11. 

Both feature a large population trapped on a ship forced to fend off enemies who appear to be attacking them for no apparent reason. While the society Infinite Ryvius descends into chaos, Macross' society is still maintained very well, but the similarities of having the fight off the enemy are very obvious. 

Both are mech animes with deeper, intricate plots that also have a lot of psychological warfare. Not to mention, quite a few similar characters 

The stories are about space adventure in the single spaceship that have a specific name presented in the title of the anime. Sometimes characters are in the complicated relationship or other way round don't care about each other. And of course both anime are created by the same studio. 

Sunrise, heavy space drama's, hard romances, incredible settings, and phenomenal music from the same composer. Superb quality in both and if you like Seikai no Monshou continue with its sequels. 

Politically charged, sci-fi drama with some action. While Infinite Ryvius focuses on the internal power politics of the spaceship at hand, Planetes addresses the ethical issues behind the ideology of science and capitalism. If you were fascinated by the issues of power and capitalist hegemony here, you will surely enjoy the political terrain underneath Infinite Ryvius. 

Both series share the premise of youngsters wrongly accused of terrorism and being on the run. They also feature the mundane goings on inside their respective vessels. Ryvius is a bit more mature and depressing however. 

Kokoro Connect and Infinite Ryvius are both similar in that they amplify the angst and drama of youth. Things are very emotional, and taken very seriously (although both shows also have a good sense of humor and plenty of romance, which is where half of the emotion stems from). If you loved one of these shows for this reason, you will likely love the other one. I gave them both 9's, so personally I think they both are phenomenal.  

- Both are set in an isolated place. Mugen no Ryvius in a spacecraft, and Shiki in a rural village. - Both have saboteurs/attackers whose identities are unknown to the main characters, but are made known to the viewer. Mugen no Ryvius with other space voyagers (is that what to call 'em??) and Shiki with vampires. - Both series' characters go through psychological deterioration. Mugen no Ryvius' characters start infighting, make stupid decisions, etc. Shiki's characters do similar things. - Both are somewhat similar in formula to a 1954 novel by William Golding, titled Lord of the Flies, if anyone even remembers that classic anymore. - Both have supernatural forces at work, Mugen no Ryvius with the Sphix, and Shiki with vampires. read more 

both series have giant robots. a mysterious character that is part of the team but no one knows where it came from another even most misterious character that just watches them and then vanishes. both have a very simmilar atmosphere where there is a lot secrets kept away from the characters and they slowly start figuring out what is really going on 

In the beginning, there are normal teenagers, who are nice to each other. But then, along with changing circumstances, the darker parts of their personalities emerge. A drama develops, in which the actors loose their rationality and get more and more driven by their passion. Conflict and violence occurs... I love it when characters are driven to their extremes, which is one of the reasons why I would count School Days and Mugen no Ryvius to my favorites. 

Both are psychological mecha anime, where fighting is not in the foreground. They are fairly dark and tend to be quite easily overlooked. 

Being chased across space with the crew being slowly broken down physically and mentally.  

both are mostly set in space, a lot of drama and great music. Geneshaft is more action oriented while Mugen no Ryvius is a bit darker exploring the nature of human interactions when there is not any clear authority. Also both have a mecha robot in a space ship built from alien technology 

The main characters share the same personality traits with the twists. They both are based on space travel and a huge manmade spacecraft.  

Both stories feature a basic "lord of the flies" story of a group of kids finding themselves stranded without adults and needing to find a way to survive their situation and eachother. Ryvius took place on a space ship with a large cast of children trying to survive military attacks over a huge misunderstanding. Uninhaited Planet focuses on a much smaller group of kids that crashed on a wild planet after the ship they were taking their field trip on blows up. It follows their trials and tribulations as they encounter wild monsters, pirates, alien organisms, unexplained phenomena, and even their clashing personalites.  read more 

I couldn't help but think of Infinite Ryvius while watching Eureka Seven. Although very different shows, the characters, interactions, and development between the two casts are very comparable. Both shows manage to develop a large cast very well, both with younger teen leads. There's also a lot of angst in these shows, but hey, people have issues right? The payoff for both is really incredible. 

Both series have great intensity and drama withing their large casts of characters. Though their stories are not quite similar, they both take you on a joyride through the twists and turns in the plot. And the awesome mecha action. 

Both series feature a group of flawed teenage characters who are forced to overcome a mysterious emergency within a science fiction context they don't entirely understand. They will experience moments of irrationality, emotional stress and internal tensions that will divide their community as a result of human weakness. While Infinite Ryvius places more of an emphasis on the slow development of the cast and on the establishment of different forms of government led by children without adult supervision, Revisions tells a comparatively faster-paced story about the relationship between destiny and heroism as well as the consequences of time travel. 

Stellvia represents another solar system wide destructive event, and another group of girls and boys are asked to defend their lives in a never declared war against unknown enemies. Both are set on a peaceful Space Academy, quickly transformed forcedly into a military outpost. Other similarities follows: an hidden and powerful secret weapon driven by students, background political intrigues, and the continuous fluctuation from individual competition to group cooperation strengthened by critical times. 

Both are really dramatic and have themes of people losing it. Both have some romance themes and battles ( though there are more violent, shounen anime-ish battles in X ) and both main characters in each deal with the stress of lives in their hands 

Both stories take place in distant future and deal with having to survive at a spaceship for a long period of time while fighting pursuers and searching for a place willing to accept travelers. Both offer interesting psychological insights. 

Second part of Guilty crown is a dead ringer to Mugen no Ryvius: bunch of students left to 'figure things out'. Political power struggles, betrayals, oppression ... all happening under the menace of a external threat  

If you liked any of the aspects mentioned here in one of the series, you might like the other. Both have children as main characters who get involved in a situation that by far surpasses what they are able to do. While trying to survive (Infinite Ryvius) or trying to accomplish what they believe in (Gundam Wing), they are labeled terrorist and make enemies out of those who they belong to or those who they want to protect. Both series share politics and human emotions/actions as themes, even though in different scales: Gundam Wing is more focused on the philosophy of politics and human ideals, while Infinte Ryvius is more focused on lack of rules and human behaviour in extreme situations.  read more 

FIGHTING ROBOTS IN SPACE~ Also they both deal with the stress of people's lives and trying to save an enormous amount of people...in space ( well...at one point, anyways ) 

It's been about about 8to5 year since I watched ryvius but, from the first episode of sidonia it made me think of ryvius. They have semi-similar sub plots. Ryvius is about somewhat of a militarily academy that teaches kids and teens do job such as pilot faint robots. Some thing happens to the ship to the point where all the kids are left alone and have to fend for the selves( similar to Lord of the flies). It's vary physiological. Overall it's a vary good anime that anyone should check out. Personally I'm probably going to re watch it again even though I've watched it 2to3 times already before I just don't Remember it as much as I feel I should.  read more
