''Infinite Ryvius'' (''Mugen no Rivaiasu'') is an anime series set in the year 2225 AD. A NegativeSpaceWedgie called the "Geduld Phenomenon" has created a sea of plasma stretching across the solar system in-line with the orbital plane of the planets, and the catatrophe on Earth it caused lead to a rise in space travel and the colonization of many planets. The space station Liebe Delta is a training center for children who wish to become astronauts. However, the station harbors a dark secret, which leads terrorists to sabotage it and send it plunging into the Geduld. All of the instructors on board sacrifice their lives to save the students. In the aftermath, 486 children of varying ages find themselves aboard the Ryvius, a mysterious spaceship which was concealed within the core of Liebe Delta. With limited supplies, no adult supervision, and hostile forces still after them, they struggle to escape their pursuers and form a stable society. All they want is to be rescued - but a GovernmentConspiracy has convinced the media that the Ryvius has actually been commandeered by the same terrorists who destroyed Liebe Delta, so finding safe harbor will be no easy task.

** [[spoiler:After she is assaulted, Kozue becomes a replacement for Ikumi's beloved older sister.]] Also, ** [[spoiler:Neya becomes this, unintentionally, for Conrad Viscuess's daughter, Anjay, and when he sees her for the first time, he realizes that evil has has committed in trying to kill hundreds of children to avenge his own daughter.]].

* JumpingOffTheSlipperySlope: Ikumi's [[spoiler:desire to protect Kozue drives him to turn the ''Ryvius'' into a police state.

* HumongousMecha: The Vital Guarder. The crew laugh at it when it's first discovered, as they don't see the merit i having a legged weapon operate in space, but it proves to be their greatest weapon.but you can't argue with success...

* UtopiaJustifiesTheMeans: [[spoiler:Ikumi and Heigar]]'s philosophy as captain of the ''Ryvius''.
* VillainousBreakdown: Viscuess, after seeing Neya and realizing the ''Ryvius'' really is crewed by children.

* {{Yandere}}: Actually more than it seems at first sight. Obvious one being a weird guy obsessed with a certain girl who often is seen stalking her, giving her points he earned or even [[spoiler:assaulting her boyfriend ]]. [[spoiler:Fina]], who was trying to kill her ex-boyfriend and the girl he left her for, and even [[spoiler:killed her previous ex and her friend who called his name]], is quite less obvious at the beginning. [[spoiler:Ikumi]] showed some traits when he [[spoiler:took over entire ship]] to make sure his girlfriend will be safe.
* YoungerThanTheyLook: Blue, Criff, and Lucson qualify.

* JerkAss: Yuki, most of the time.
* JerkWithAHeartOfGold: Arguably Yuki and Ran.

* LargeHam: Lucson, to the annoyance of others.
* LittleMissBadass: Michelle, especially after her imprisonment.
* LivingShip: [[spoiler: All of the Vaia Ships.]]

* LoveRedeems: Criff Kei and "Charlie".

* TheMutiny: [[spoiler: Usually happens once every five episodes.]]
* MyGodWhatHaveIDone: Several instances, but most notably [[spoiler:Ikumi and Faina]] in the penultimate episode
* NonActionGuy: So very much Kouji.

* OneWingedAngel: Grey ''Geshpenst''.

* POVSequel: The manga

* PuttingTheBandBackTogether: The final episode.
* RebelliousRebel After he's overthrown, Blue abandons his band of delinquents.
* ReplacementGoldfish: [[spoiler:After she is assaulted, Kozue becomes a replacement for Ikumi's beloved older sister.]] Also, [[spoiler:Neya becomes this, unintentionally, for Conrad Viscuess's daughter, Anjay, and when he sees her for the first time he loses his mind]].

* SciFiWritersHaveNoSenseOfScale: Averted; there is no FTL and the ''Ryvius'' spends months traveling between planets.
* ScholarshipStudent: Juli Bahana.

* SheIsNotMyGirlfriend: Kouji and Aoi.
* ShutUpKiss: [[spoiler:Fiana]] does this to [[spoiler:Koji]] to keep him from [[spoiler:breaking up with her.]] It doesn't work.

* SpaceFriction: Averted.

* SpaceWhale: [[spoiler: The Vaia; more like space-squids, actually.]]
* SpaceshipGirl: [[spoiler: Neya.]]

* StrawVulcan: Heigar - [[spoiler: which makes it even more creepy when he cracks.]]

* TechnoBabble: Most of the conversation occurring in the Vital Guarder control room.
* TeenageWasteland
* ThematicThemeTune
* ThemeNaming: Blue ''Impulse'', Crimson ''Dicastia'', Grey ''Geshpenst'', Black ''Ryvius''.
* TheCaptain: Goes through four of them over the course of the series.
* TheVamp: Michelle Kei.
* ThisIsADrill: The Blue ''Impulse'''s Vital Guarder, the Vorticular Drill.

* ThrownOutTheAirlock: Threatened a few times, but never actually done.
** There were two people dragged behind the ship on lines (in spacesuits) as a punishment at one point, however.
* TookALevelInBadass: Koji towards the end.
* TreacherousAdvisor: [[spoiler:Heigar]] turns down the position of captain, preferring to be an advisor instead. He even goes so far as to engineer a coup to set himself up in this position. Naturally, he dreams of being TheManBehindTheMan.

* EasilyForgiven: A lot of people do a lot of bad things over the course of series and every one of them, even [[spoiler:Faina, Heigar and Ikumi]] are forgiven for their crimes. [[spoiler: Learning that the Vaia was subjecting everyone to SanitySlippage probably helped.]]
** The last episode, that takes place nine months after the end of the main events, strongly suggests that even [[spoiler:Blue and Ikumi]] got a second chance.

* EarthShatteringKaboom: [[spoiler:Hyperion-shattering kaboom]].
* EmpathicWeapon: [[spoiler: Neya and the other Sphixes of the Vaia ships; the effect is two-way with the ships' captains -- if they have any.]]

* EvenEvilHasStandards: Even Blue, who took over the ship at gunpoint in the earlier episodes, is disgusted by what [[spoiler:Ikumi]] degenerates into by the end of the series.

* FailureKnight: Ikumi is motivated primarily by [[spoiler:the death of his sister]].
* GeneralRipper: Conrad Viscuess, captain of the Grey ''Geshpenst''.

* GovernmentConspiracy: The reason why the children aren't rescued right away.
* GratuitousForeignLanguage: The names of the Vaia ships. "Impulse" is obviously English, "Dicastia" comes from the Greek word, "dikastis," meaning judge, and "Geshpenst" comes from the German for ghost. "Ryvius," on the other hand, seems to come from a variety of English words and phrases, including "Leviathan" and "Reawake us." As for Brattica...your guess is as good as mine. [[GratuitousForeignLanguage Gratuitous Gibberish]], perhaps?
** However, almost all of the English used in the series is grammatically correct.

* AHouseDivided: Occurs with great speed.
* HumansAreFlawed
* HumongousMecha: The Vital Guarder. The crew laugh at it when it's first discovered, but you can't argue with success...
* ImmuneToBullets: Airs Blue shoots Neya, to no effect
* ImpossiblyCoolClothes: Neya. Just... Neya. [[LampshadeHanging Lampshaded]] when she attends a party.
* InfiniteSupplies: Averted: the limited supplies on the ''Ryvius'' are a major source of tension amongst the crew.

* ApocalypseHow: [[spoiler: A single Vaia Ship can do a Planetary/Physical Annihilation. A second Geduld Phenomenon would cause a Stellar/Physical Annihilation.]]
* ArtificialGravity: [[spoiler: Only in Vaia Ships]]; the depiction of gravity in conventional ships is pretty realistic.
* AscendedExtra: Cullen starts the series as a background character collecting music; she evolves into an ActionGirl mecha "pilot" and Yuki's girlfriend.

* TheBattlestar The ''Ryvius'', the ''Impulse'', the ''Dicastia'', and the ''Geshpenst''.
* BettyAndVeronica: Aoi and Faina are this for Kouji.

* BookEnds: The [[TheTeaser cold openings]] to the first and last episodes.

* BrotherSisterIncest: Part of [[spoiler:Ikumi]]'s backstory
* BreakTheCutie: [[DysfunctionJunction Too many examples to name.]]
* BridgeBunnies: The Zweis.
* ButtMonkey: Lucson Houjou, the self-proclaimed leader of the Zwei and captain of the ''Ryvius''. After being deposed, he is forced to work as the ship's janitor, frequently has his clothes stolen, and is constantly ridiculed by his fellow students. Even eight-year-old Pat thinks Lucson is "uncool."
** However he's redeemed in the end, [[spoiler:when his fellow students offer him the position of Captain and seem to treat him in a more friendly way; even Heigar seems to be more mellow towards him]].
*** Kouji and Charlie should probably be under this entry as well.
* CainAndAbel: [[spoiler: Kouji and Yuki.]]

* CharacterDevelopment: Everyone goes through it, with the biggest examples being Kouji, Charlie, and Lucson.
* ChekhovsGun: There is exactly one gun aboard the ''Ryvius'', stolen from one of the terrorists. It naturally plays an important role.
* ChildhoodFriendRomance: Kouji and Aoi.

* ComingOfAgeStory

* {{Delinquents}}: Airs Blue and his gang.
* {{Determinator}}: Conrad Viscuess.
* DidTheyOrDidntThey: [[spoiler:Kouji and Aoi at the end of Episode 21. Nothing explicit is shown, but the two are seen embracing, then falling onto a bed. The manga makes this scene much more obvious that they had sex.]]
** [[LampshadeHanging Lampshaded]] in an episode of Ryvius Illusion, where Kozue sends "fanmail" asking whether they "did it." Needless to say, [[spoiler:Aoi]] is not pleased...

* {{Driven to Suicide}} Airs Blue, at one point. But he doesn't go through with it. [[spoiler:Viscuess on the other hand does, once he realizes he's thrown the entire weight of Earth's naval forces behind destroying a ship crewed by ''children'']]

* AccidentalMisnaming: In Episode 4, Team Blue nicknames Good Turtleland III "Charlie." Despite his insistence on being called by his real name, it is [[OnlyKnownByTheirNickname all but forgotten]] within a few episodes. Viscuess also, puzzlingly, refers to the ''Ryvius'' as the ''Brattica''

* ApocalypseHow: A single Vaia Ship can do a Planetary/Physical Annihilation. A second Geduld Phenomenon would cause a Stellar/Physical Annihilation.
* ArtificialGravity: Only in Vaia Ships; the depiction of gravity in conventional ships is pretty realistic.

* AxCrazy: Most notably the captain of the ''Blue Impulse'', though all of the captains of the Vaia Ships go insane in combat. It's implied that the {{phlebotinum}} is detrimental to their mental health.

* BewareTheNiceOnes: When Kozue is [[spoiler:beaten]], Ikumi snaps ''HARD''.

* CainAndAbel: Kouji and Yuki.
* CameBackWrong: A rather loose case: [[spoiler:Neya based her humanoid form off the body of a dead soldier floating out in space near the ''Ryvius'' at the time of some [[NoodleIncident vaguely-alluded to incident]]. That soldier was Anjay Viscuess, Conrad Viscuess's daughter. This leads to Conrad momentarily thinking his daughter had come back from the dead when Neya confronts him on the bridge of the ''Geshpenst'']].

* CoolStarship: The Vaia ships.

* EasilyForgiven: A lot of people do a lot of bad things over the course of series and every one of them, even [[spoiler:Faina, Heigar and Ikumi]] are forgiven for their crimes.

* EmpathicWeapon: Neya and the other Sphixes of the Vaia ships; the effect is two-way with the ships' captains -- if they have any.

* KnightTemplar: Ikumi
* LargeHam: Lucson

* LivingShip: All of the Vaia Ships

* TheMutiny: Usually happens once every five episodes

* NoNameGiven: Neya is a major character who is introduced in the first episode, but we don't learn her name until near the end of the series. The other two Vaia ships aren't named either, though in fairness they don't even make it out of drydock by the time the ''Ryvius'' is cornered

* SapientShip: The Vaia Ships are mostly technological, but each has a living [[SpaceWhale Vaia]] at its core. The Vaia are sentient, though only one is a full-fledged SpaceshipGirl.

* SomeKindOfForceField: The Vaia Ships can control gravity and deflect attacks by bending space.

* SpaceMadness
* SpaceWhale: The Vaia; more like space-squids, actually.
* SpaceshipGirl: Neya.

* StrawVulcan: Heigar - which makes it even more creepy when he cracks.

* EarnYourHappyEnding: [[spoiler:Despite the many hardships the children go through, the entire main cast survives, as do most of the recurring extras. Most of the kids return to the Ryvius to help in the development of Vaia ships and a thousand years later their efforts lead to humanity being able to evacuate the solar system it is destroyed by the Geduld.]]

* DistantFinale The very end of the final episode takes place thousands of years after the events of the series.

* EarnYourHappyEnding

* EvolvingCredits

* WeaselMascot: Rafra.

While the series has LoadsAndLoadsOfCharacters, with at least 33 named recurring characters, most episodes focus on a few core cast members. There's Kouji Aiba, an OrdinaryHighSchoolStudent (or astronaut-training equivalent thereof) and main protagonist; his younger and far more violent brother Yuki Aiba; their childhood friend Aoi Housen; the charming but fervent Ikumi Oze; and the mysterious girl in a strange pink outfit who nobody recognizes and who seems to appear and disappear like a ghost (Neya). Other significant characters include the arrogant Zwei (elite cadet) leader Lucson Houjou, the popular and talented Zwei member Juli Bahana, the vicious gang leader Airs Blue, and the religious girl Faina Shinozaki.

* LoadsAndLoadsOfCharacters: Nearly five hundred children are on the ''Ryvius''! In addition, there are about fifty named characters. Naturally, the series focuses on just a few, and organizes many of them into {{Cast Herd}}s.

* RecycledINSPACE: ''Literature/LordOfTheFlies''... [[AC:in space !]]

* BatmanCanBreatheInSpace: [[JustifiedTrope Justified]] in-universe. Several characters (even Radan, aka "[[FanNickname Pillow Boy]]") are seen doing repair work on the hull without spacesuits, as the ''Ryvius'' is capable of creating both an artificial gravity field and atmosphere around itself.

* AccidentalMisnaming: In Episode 4, Team Blue nicknames [[UnfortunateNames Good Turtleland III]] "Charlie." Despite his insistence on being called by his real name, it is [[OnlyKnownByTheirNickname all but forgotten]] within a few episodes. Viscuess also, puzzlingly, refers to the ''Ryvius'' as the ''Brattica''

* {{Transgender}}: [[spoiler:Criff]]. For all intents and purposes she's a woman but at one point Michelle calls her [[spoiler:"big brother."]]. Confirmed by the [[WordOfGod official]] character [[http://www.sunrise-inc.co.jp/ryvius/character.html profiles]].

* AllGirlsWantBadBoys: Played straight from Episodes 16-25 with [[spoiler:Juli and Blue]]; averted with [[NonActionGuy Kouji]], whom both Aoi and Faina are in love with.

* HeroicSacrifice: The instructors on Liebe Delta, who sacrifice themselves to save the children. Particularly notable is Pat's father, who gets FamousLastWords as he begs for the plan to work while being crushed and incinerated by the Geduld

* EverybodyLives: Sort of; [[spoiler:All but two named children who survive the initial disaster survive to the end]]).

** Gender-flipped (Or not, see {{Transgender}} below) with Charlie and Criff. While Charlie is an easily manipulated, but good at heart, boy, Criff is a manipulative juvenile delinquent, until [[spoiler:she realizes that Charlie genuinely loves her in Episode 16.]]

* DivorcedInstallment: According to some sources, ''Ryvius'' is actually based on a rejected pilot version of ''Anime/SpaceBattleshipYamato'' written before Creator/LeijiMatsumoto's involvement in its development.
