Eureka Seven (AKA Kōkyōshihen Eureka Sebun or Psalms of Planets Eureka seveN) is a 50-episode sci-fi mecha anime first broadcast in Japan from 2005 to 2006 and produced by acclaimed animation Studio BONES. It was later picked up in the US by Cartoon Network's [adult swim] block. It is currently airing on television on Toonami.The story concerns Renton Thurston, a 14-year old boy leading an uneventful life with his grandfather after losing his father (who was involved in narrowly averting a planetwide catastrophe) and sister (who set out to look for her father, and who Renton regards as a mother figure). His life is changed forever, however, when he meets and falls for Eureka, a mysterious LFO pilot who serves in Gekkostate, an anti-military group under the guise of a counter-cultural commune. The rest of the series focuses on Renton and Eureka's growing relationship and involves general themes of love, acceptance, and the tolls of war. It also involves Sky Surfing mecha, super-intelligent alien lifeforms, evil master plans, more than a few mind screws, and more musical references than one can count.Perhaps most notable for being a sci-fi action show in which the hero's romance is at the very core of the story; none of the usual tacked-on romantic subplots or sudden end-of-series couplings here. The often-bumpy evolution of Renton and Eureka's relationship (along with a couple of others) forms the backbone of the entire plot.Two Video Games and two manga series were later made, the games and one series serving as a prequel focusing on other characters (two of which did a split second cameo in the show) and one manga series set in an Alternate Universe. That one is noticeably darker, with severe damage and death among the main cast, actively malevolent Coralians, and a Downer Ending.A sort of Compilation Movie premiered in 2009, subtitled Pocket Full of Rainbows in Japan and Good Night, Sleep Tight, Young Lovers in North America. The movie is set in an Alternate Universe from the series, but still features most of the main characters.Shout Outs now have Their Own PageOh, and it's pronounced Eu-Recca, not You-Ree-Kah. It kind of sounds like "Erika", but with an accent (especially if you speak English).A Sequel Series, Eureka Seven AO, debuted in April 2012.If you want to enjoy the series without spoilers, stop reading NOW. Most spoilers are covered, but a decent amount aren't. Don't even think about going to the Eureka Seven AO page either. You Have Been Warned.NOTE: Tropes specifically found in Eureka Seven: Pocket Full of Rainbows should go on that page, not this one.
Eureka Seven contains examples of the following tropes:
Aesop Amnesia: Eureka's kids learn at least twice directly, and numerous times by being on the ship, that Renton will do anything to protect her. They completely forget this in the last few episodes and a painful, both for the viewers and for the characters, reeducation takes place.
All Men Are Perverts: In "Date of Birth", when Renton is caught looking in a porn magazine for advice on how to patch things up with Eureka after a miscommunication regarding her relationship with his father, the other members of the Gekko think that the tension between the two is because Renton has been pressuring Eureka for sex. While the women on the ship counsel Eureka about resisting unwanted advances, the men come to Renton's room with whole stack of porn and start redecorating his room according to instructions in the magazines to make an atmosphere suited to seduction, well, with the exception of Holland, who is NOT amused, with predictable results.
Some characters like Holland's animosity with Renton are changed in personality or behavior.
The symbolism is drastically different the anime showing lots of color and using heartfelt words like "love" and "emotion" frequently, while the manga has much dark imagery and lots of blood
Certain characters die in the manga that do not in the anime Dominic for example.
Many characters from the anime outright don't appear in the manga (Lady Sakuya, Master Norb, Ray and Charles, many side characters and one-offs) and one video game only character (Ruri) gains a prominent role in the main story line.
The relationship between Renton's family and the plot changes: Renton's grandfather Axel helps repair the Nirvash during the story, as well as being its builder. Renton's father Adrock is still a hero, but was also Holland and Dewey's personal mentor who got assassinated by Dewey as opposed to disappearing by stopping the Summer of Love Incident. Diane, Renton's sister, still leaves home and disappears but her relationship with Holland is practically non-existent and her ultimate fate is not revealed.
The Coralians are totally different between each media the anime points them as noble beings who want to live in peace with the people of the Earth, while the manga shows them as Eldritch Abominations hellbent on devouring planets
The endings are totally different one very upbeat with a happy ending, the other extremely depressing with a much darker and sadder tone.
Alternate Universe: The beginning of Episode 33, where they show what it would be like if the cast was on Earth (before the scub came) and surfed instead of lifted.
Anemone and Dominic. The latter barely even qualifies as a villain.
The Beams, who aside from their Ax-Crazy behavior regarding Eureka are decent people.
Arc Words: This show is a breeding ground for arc words. "Coralians", "Great Wall", "Oratorio #8"...
Artistic License - Physics: The Limit of Questions is actually based on real physics, though stylized. The implication is that there's such sheer informational density in the Scub Coral biomass that it would cause a black hole, which is scientifically plausible.
Hollywood Skydiving is both present and Averted; on the one hand people have conversations while falling in the climax, but on the other Giant Robot Hands Save Lives is averted in every instance as they match speeds before picking up falling people.
The revelation in the climax that the visible world is actually a shell 100 kilometers thick above the actual Earth, made from Scub Coral, also includes atmosphere and sunlight below the ground. Justified in that Scub Coral can bend reality.
Ascend to a Higher Plane of Existence: What humans and Coralians should do in order to avoid reaching the Limit of Questions, thereby destroying the universe. Eventually it happens; partially. The Scub Coral split universes; one where humans live and one where they live, and one day they will communicate again.
Badass: Holland. In Episode 42, He jumps off from Matthieu's LFO in mid-air, to get to his own, which is hurtling towards the ground. And succeeds at it. Then in the penultimate episode, he takes a good portion of the Ginga by crashing his LFO straight into it and unloading his entire arsenal. Then, gets out and continues on foot.
Renton has some very prominent moments of badassery in Nirvash. Any other time though... he's The Chew Toy.
Badass Grandpa: Axel Thurston proves to be a one of the highest order when he successfully rams an armored transport carrier with a forklift, blows his workshop up to slow down the military, then dashes for (and then,off) a cliff so he can send the customized LFO board for Renton's mecha to him without panicking once.
Battle Couple: Renton and Eureka, obviously. The full potential of their Humongous Mecha is only unlocked by The Power of Love. Also, Charles and Ray Beams, Hilda and Mathieu qualify as well, if you do count them as a couple. There are also couples where one member takes part in combat while the other plays more of a supporting role in the battle: for example, Holland (the front-lines fighter) and Talho (the support).
Beta Couple: There are two, really. Talho and Holland. And Anemone and Dominic.
Subverted since Dominic and Anemone face loads of troubles in their relationship throughout the series, and thus their relationship is more of a parallel to the main pair than a mere Beta Couple. The same may also be said for Holland and Talho. A true Beta Couple from the series would be Moondoggie and Gidget.
Berserk Button: Renton goes brutally psycho over his opponents at the end of Episode 20 in a deadly combination of his love for Eureka, his hatred towards Holland and frustration with his own immaturity. It does not end well (See Freak Out entry below).
Big "NO!": Holland does one after they lose contact with Dominic.
The Big Damn Kiss: Three of them as a matter of fact! The first occurs in Episode 48 between Dominic and Anemone and the other two in the final episode between Eureka and Renton. And did I mention that two of these take place in mid-air?
"Smickers" bars, "Bind Aid" bandages, "Rersi" cola and "Yuhoo", among others.
In Episode 13, there's also a brief sighting of what looks like a Domino's Pizza sign (it's in the background a few moments after a little girl throws a flower pot at Dominic). Since it's so far away, the only noticeable difference is in the dots.
Body Horror: When Eureka's Coralian features begin to show towards the end of the series, one of the first stages of her transformation included growing giant luminescent boils growing all over the left side of her body.
Broken Pedestal: Holland and the rest of the Gekkostate for Renton, who idolized them before joining. Holland particularly, when he beats Renton up and acts like a child. By the end of the series it's clear he respects them immensely, but his view of them is now grounded in reality.
Chekhov's Gun: A lot of things from early, lighthearted episodes become either important later on, or serve as heart-breaking reminders of when things were happier and come back to bite everyone.
In-Universe, Holland wonders if he'll ever find a use for the bottle of luminescent yellow liquid that was given to him by Tiptory at Ciudades del Cielo.
Chekhov's Gunman: Gulliver spends most of the series sleeping or lying around, but in Episode 48 he's crucial to bringing Dominic and Anemone together.
The Chew Toy: Renton. He stops being one after he comes back from Ray and Charles. Any misfortune he suffers afterward isn't very intentional, or is equally shared with other people.
Color Failure: Happens to Renton occasionally in some of the earlier episodes, mostly when other characters point out things that make it seem like he has no chance with Eureka. The kids give it to him so hard that he emits an aura that extends out to the scenery around him.
Comfort Food: At a loss for what else to do in the midst of his Heroic BSOD, Renton eats bag after bag of potato chips in "Runaway".
Darker and Edgier: The manga is much darker than the series. The in-depth approach to the war themes and elevated violence pretty much set that. On the other hand, everything is so busy going wrong that the characters are generally a lot nicer.
Dead Man Switch: Dewey uses his suicide to attempt to force Anemone or Eureka to become an active nerve cluster and destroy the world.
Deface of the Moon: A normal couple would carve their names surrounded by a heart into a tree. Renton and Eureka decide to be a little more obvious about it and carve theirs onto the surface of the moon.
Dropped a Bridge on Him: Episode 48 drops one on a good chunk of humanity via shifted leylines and Kill Sat pieces, apparently targeting people with Desperation Disease, including William and Martha. The specific reason why those people were targeted in particular is never explained.
the manga does the same thing by the end
Duality Motif: The Nirvash, in it's third form. For most of it's appearance you can only see its left eye, which is blue (Matching Renton). When it lifts its head to finally show it's right eye, which it had been covering by cocking it's head to the side, you see the eye color is purple (Matching Eureka).
Empathic Weapon: The Nirvash, though only Eureka can understand it, and TheEND to some extent.
Emotionless Girl: Eureka before taking the kids in as her own. She was still pretty emotionless until she and Renton became closer.
Empathy Pet: Subverted. Gulliver is stoic, unwieldy, and a general annoyance to everyone but Anemone. He seems to be some sort of trapar-manipulatingMon. He becomes light enough that Anemone can lift him easily whenever she plays with him, but can also gravitationally weld his fat rear to your bunk if that's where he wishes to nap. He does become more affectionate towards Dominic toward the end of the series, often riding on his shoulder, as Anemone is becoming generally softer and less psychotic. So maybe in that sense the trope is played straight.
The End of the World as We Know It: The Coralians threaten to negate reality itself by violating physical laws governing thought/space (similar to a black hole, which is a rupture in space/time) should the main node wake up from a self imposed sleep.
Enemy Mine: Occurs in Episode 13, in which Renton and Dominic are forced to work together in order to save Eureka and Anemone.
Epic Fail: During their final confrontation, Dewey goes after Holland with the sword he always keeps at his side. Holland parries with his gun at first, then just dodges, causing Dewey to snap the blade like a twig on the metal floor. He immediately complains about the sword being fake.
Everything's Better with Rainbows: The whole series. One of the most memorable scenes from the first season takes place in a sea of rainbow clouds. It's even named just that.
Evil Counterpart: Anemone, to Eureka. Subverted in that Anemone's not a Coralian, but rather a drugged-up and experimented human girl who suffers from Desperation Disease. She also performs a last-minute Heel-Face Turn.
Evil Plan: Dewey's plan to wipe out the Coralians, and humanity with them.
Exact Time to Failure: The Antibody Coralians can only remain alive for 1246 seconds (20 minutes 46 seconds).
Subverted by Gonzy in the manga, as he opens his eyes numerous times
Fan Disservice: One of Hap's few prominent scenes in the series was done while Holland was washing his hands and he was sitting on the john. Naked. Which we saw. Also one of the bits of series material they saw fit to reuse in The Movie.
Fee Fi Faux Pas: In Episode 16, Eureka is quiet because she's worried about Renton being a better pilot for Nirvash. Renton tries to get her to talk by bragging about being a better pilot for Nirvash. With Renton only being a kid though, he really has no idea how inconsiderate he was being.
Filler: "Join the Future". The only thing even vaguely significant throughout the whole episode is the military press conference shown during very last minute, and even then the viewer probably could have assumed the events that happen there.
Hilda: "When I think of the Nirvash as a female friend, everything falls into place."
Episode 40, Renton, Eureka, the children, and Norb go to visit Sakuya. In her antechamber, there is a huge globe of the Earth, surrounded by the dome of the room.
Freak Out: Episode 20. After the events that happened in the mine resulting in Eureka being covered in scub coral, Holland takes on a mercenary mission to help, but gets pinned down by enemy fire. Renton runs off with the Nirvash to rescue him. Due to the rising tension between him and Holland over the entire incident, Renton loses it and goes COMPLETELY BERSERK!, taking his frustrations out on an enemy KLF. This eventually causes a hallucination in which Renton thinks a blob overtaking the Nirvash, eventually reflects his own face. It isn't until he sees the wedding ring on the dismembered arm of the pilot he just killed before he throws up and stops. Results in Renton's Heroic BSOD and later him leaving the Gekkostate for a while.
Freefall Romance: Happens more than once. These kids don't seem at all fazed to find themselves skydiving with no parachute. In fact, just falling isn't dangerous enough, so in the third opening this happens in the middle of a Free-Fall Fight.
Freudian Excuse: Ever wonder why Holland acts like a jerk and is emotionally immature? Dewey Novac is his brother. Be very very thankful that he's as stable and well adjusted as he is. His childhood could not have been fun. It makes things all the more creepy when you realize that Holland is 10 years younger than Dewey, and that Dewey has a very disturbing penchant for surrounding himself with very young children, at the very least preying on their insecurities to turn them into mindless killers, if not doing... other things to them.
Frickin' Laser Beams: Homing lasers as well as the more conventional goes-in-a-straight-line versions.
God Was My Co-Pilot: The ending reveals that Gonzy, the old guy who sits around drinking tea, is actually a Coralian, watching over Eureka and Renton.
Averted in the manga, where Gonzy was just a former sage, and completely human.
Gratuitous English: Tons of LFO and lifting related jargon are in English. Of course, there's also the plain, completely context free English...
Charles:"Shōkai shiyō! Itoshi no MY WIFE."note Let me introduce you to my darling wife.
Gratuitous Spanish: Ciudades del Cielo, Controlado, Pancha, Yucatan Iglesias... Many of the plot-relevant areas have Spanish names, but numerous places shown on maps throughout the series are properly split among numerous languages including English and from the Eastern Bloc of Europe.
Groin Attack: In the episode Vivid Bit, Talho kicks an attempted rapist between the legs.
Happy Ending: For the characters, though the world, city, and technology suffered heavy damage. Averted in the manga.
Heel-Face Turn: Many characters, including Anemone, Dominic, and Jurgens's entire crew. And TheEND, complete with it changing color from black to white.
Heroic Sacrifice: TheEND saves Dominic and Anemone from a massive explosion, getting mostly disintegrated in the process.
The upper echelon knew it was Earth, implying they came back because there really was just no where else to go. In the manga however, there is no indication of this, and humanity really was unaware they were on Earth, or at least, Dewey and the Sages hadn't seen fit to tell them before he died.
The series creator and head writer, Dai Sato, is a known electronic musician himself, together with his friend Kengo Watanabenote Yes, Ken-Goh is a homage to him, has once managed his own record label.
Idiot Ball: While pounding your own arm with a rock to make it match to your loved ones is a pretty romantic thing to do, it is also very stupid and irresponsible to do with no immediate medical support at hand and short on supplies and shelter, Renton...
Important Haircut: Talho and Eureka, at different points. Eureka goes through 3 in the series and 3 in The Movie. The series haircuts also signify the caterpillar metamorphosis theme.
It's Personal: Ray and Charles Beams oppose Gekkostate not merely because of their affiliation with the military, but also because of resentment toward Eureka, whom they believe to be to blame for Ray's infertility.
It Is Pronounced Tro PAY: Eureka and Anemone's names don't have any long vowels. This is mostly a result of Japanese pronunciation guides.
Strangely, the German dub averts this, going with the classical German "Eu-REH-Kah" pronunciation, but instead putting the emphasis on the first syllable, instead of the middle one. It sounds equally strange, yet somehow more familiar.
Jerk Ass: For the first half of the series, the Gekkostate crew is at best apathetic towards Renton, with Holland and Talho getting full on abusive at times. The only solid exception is Eureka. They all take advantage of him, even when he's working his hardest, show barely any appreciation for when he saves their asses with his piloting skills, and the male members send him on a hazing mission that took him way too close to death by yakuza.
The only thing that separates Holland from being a straight up complete asshole is his desire to stop Dewey's plans and his kindness to Eureka. Other than that, he constantly abuses Renton during the first half of the series until he finally realizes how damaging his actions are to Renton and it takes a while for him to have a good relationship with Talho too.
Madness Mantra: Episode 28, after Charles Beams dies, Ray spends most of an episode humming the two-note melody of "Get It By Your Hands". Made even more creepy by the fact that the audience barely sees her, just hears the humming over scenery shots of the rooms she's trashed. It's horribly and heartrendingly clear that she's completely lost it when we see that she's set the table for herself, Charles and Renton with their three mugs.
Magic Skirt: Talho's first outfit. Both averted and lampshaded in one manga chapter, when, after Renton wins a fight for food in Gekkostate, Matthieu effortlessly lifts Eureka's skirt to show him what's underneath and Renton drops his prize.
Matrix Raining Code: Compac Drives have it when activated, with concrete words showing occasionally such as Eureka, Sakuya, and Renton.
Dominic's kindness to Anemone makes him more sympathetic.
Gulliver is a literal one by being the subject of Anemone's kindness.
According to a flashback in one episode, the kids are sort of this for Eureka; before they came along, she was cold, mechanical, and emotionless, but when she finds three children huddled in the bodies of a surrendering group of people she had just slaughtered, she realizes what she's done and takes them in, becoming the quiet, motherly type we become familiar with.
No Biochemical Barriers: The crew briefly muses on the biological compatibility of Eureka (human-form Coralian) and Renton (human). The resident doctor confirms that there's nothing preventing it.
No Loves Intersect: You won't see any full fledged Love Triangles (or Dodecahedrons) in the whole show. It is subtly implied that one of the three of Renton's classmates/neighbors has a crush on Renton, but it never went further than that and he never sees them again after the first episode.
Holland/Talho/Eureka probably counts, actually. It's just that unlike most anime love triangles this one actually gets a conclusive resolution.
Renton can be added to that equation, too. It's implied that part of the reason Holland is so harsh with him is that both Eureka and Talho have taken a liking for him. He gets jealous when Talho mutters "You've gotta get it together, Renton" in her sleep, and is upset because Eureka chose Renton instead of him.
The three kids, especially Maurice, are counted as well since they are constantly obstructing Renton in his quest to get Eureka's love.
Let's just be clear here: Maurice points a rifle at Renton in Episode 45 because he's upset that Eureka isn't giving all her attention to him exclusively.
What makes this series different, is that Love Triangles do exist, but for once it's about the intersection of different types of love obstructing each other. For example, Holland acts as Eureka's protectorate and effectively maintains a sibling/parental relationship with her, but he's strongly romantically involved with Talho, who resents Eureka because Holland uses his devotion to her as a way to escape from his responsibilities and relationship with Talho because he has the emotional maturity of a teenager and has no idea how to face an adult relationship with the woman he loves. Then Renton comes into the picture, who makes things more complicated because suddenly Eureka is investing emotionally in him, making Holland resent Renton because he is undermining his role and... Holland has the emotional maturity of a teenager. Basically, all Love Triangles surrounding Holland can be resolved by Holland growing up and acting like an adult. Which he does... eventually.
Noodle Incident: Nothing about the Summer of Love and why exactly Adroch sacrificed himself is explained directly in the anime. In fact, Adroch himself never speaks in flashbacks or in the Coralians, unlike Diane.
Not Now, Kiddo: Dewey and the Ageha Squad don't take the Gekko State very seriously. Dominic, who does, is shut down by the Ageha Squad in his efforts to warn Dewey about this.
The Omniscient Council of Vagueness: The highly vague and laughably ineffectual Council of Sages, who don't get much done except hire Dewey and then die at his hand some twenty-five episodes later.
This may be the closest thing to Truth in Television (although maybe not intentional) in the series, really (except the coral aesop). In WWII in Romania, King Carol the II, in desperation because of his weakness, called upon ex-military commander Antonescu from jail to get the country out of trouble. Antonescu soon took all of the power in the country, and had the King give up his position and leave the country the same night. His purpose has been deemed by some as suicidal as Dewey's.
Prominent in the third opening, thanks to the position, perspective, and environment of the shots. It might've been intentional, given that it was directed by an animator famous for his fluid movement style and weird deformations of the characters.
Almost the entirety of "Join the Future".
Official Couple: Several, actually. There's Renton and Eureka, Holland and Talho, Gidget and Moondoggie, and Dominic and Anemone, among others.
Organ Theft: The episode Watermelon has Gekkostate smuggling some black market organs in order to pay the bills.
Parental Substitute: Charles and Ray Beams serves as this for Renton. Of course Renton didn't have enough trauma in his life, so they end up dying shortly after he leaves them. While trying to kill Eureka and the crew of the Gekkostate.
Inverted by Charles and Ray themselves. They happily accept Renton as their own adopted child because Ray is incapable of bearing children.
Pirates: The basic setting of Eureka Seven can be interchanged with the ocean and not much will change. This makes it easier to see that the Gekkostate is essentially a group of type 2 pirates. Dewey even mentions this when told about the group.
Poor Communication Kills: In "Date of Birth", Renton discovers that Eureka knew his father. He's angry and frustrated that she never mentioned that fact. While Eureka discusses the situation with Holland and Talho, Holland concludes that Renton is trying to pressure Eureka into sex (or worse) and runs off to kick his ass.
Holland doesn't tell Renton anything, and it massively screws them both up. Which, at least, can be explained by him feeling jealous of the attention Eureka and Talho show to Renton.
Dewey either chooses not to read or is not given Dominic's report on the Nirvash and its pilots. Therefore he assumes that Eureka doesn't have a partner and will never find one, even though it's actually Renton. He therefore lets his guard down at the worst possible time. It's a mistake that costs him dearly.
This specifically. Dewey and the Ageha Squad don't take the Gekkostate as a serious threat and only Dominic does.
Red Shirt: Almost all Moon-Soono (KLF) pilots are sent to die. This actually comes back to bite Gekkostate later when some of the KLF pilots try to beat Holland up for killing so many of their comrades.
Retail Riot: In the episode Vivid Bit, Hilda gets into a massive brawl in a store having a sale.
Schizo Tech: It's the future and humans developed advanced, humanoid mechas, hover boards, and turbo-charged military ships and yet they still drive around in cars from the 1940's, listen to vinyl records, and use non-digital cameras.
Fridge Logic somewhat justifies it: The hoverboards only work on energy-flows in the same way a surfboard does with water, and are completely useless unless made from a certain material. The humanoid robots are partly organic (and not human-made organic parts either) and have only existed (or at least been used) for a little over a decade. The flying ships use the same mechanics of trapar-surfing that the hoverboards do, and trapar waves aren't always reliable in all areas (ships tend to stay on the ley-lines; i.e., trapar currents in the sky). Hell, all standard-issue LFOs and KLFs are able to transform into wheeled vehicle forms for fast transport where trapar waves are weak/absent (goodness knows how this would help them if they lost lift while out at sea). So, cars with wheels. And as for aesthetics? Isn't it obvious that these people have hard-ons for anything antiquated by now?
Scenery Porn: In every episode and opening/ending theme, expect to see beautifully detailed backdrops. Whether it's the sky, the grass, the cityscape or whatever.
Shown Their Work: Well to some degree, but the pre-print sheet of the Ray=Out magazine which uses the Pacific State picture has all the correct cut markings, color control fields and signs, the only thing missing was the back cover, because that would be printed on the same sheet, but it might be a preprint of just the cover to look at the composition of parts, which would work.
Sliding Scale of Idealism vs. Cynicism: Most of the characters who are still alive at the end of the series grow up and/or change for the better, and the whole story is permeated with the idea that the The Power of Love can accomplish anything. In short: Definitely on the idealistic side.
The Sociopath: Dewey. Patricide, genocide, global mass-murder, inhumane human experimentation, political coups, and manipulation of mass media to paint himself as a hero. Possibly paedophilia as well (judging by the Ageha Squad, among other things). He has absolutely no qualms about using, discarding, and killing the majority of the population of the planet for his own needs, including his own brother. And he seems to enjoy it. Yeah, Holland is definitely the normal one in this family.
In Episode 43 a high-speed and violent LFO battle fought by Holland is intercut with Dewey flashing back to when he killed his own father during a dance with Anemone at a ball where an upbeat and fast-paced orchestra is playing in the background.
The ball itself. Dewey points out that nobody there has any idea that the music the band is "playing" is actually a recording playing through speakers installed in the instruments.
Starfish Aliens: The Scub Coral is a colonial organism that has no means of communication besides fusion of biomass, eventually (albeit unintentionally) driving humans off of Earth, only to return sometime just under 10,000 years later. It eventually covered the planet and became sentient, realizing what it had done to the inhabitants. It also rose above the surface on pillars, leaving the original features and biology intact. At some point the power of it's thoughts became so greatly concentrated that it essentially created a thought black hole that messed with space-time, and only barely averted losing the entire planet by going dormant (Trapar is literally thought). When humans return, the humanoid Coralians, Sakuya and Eureka, are created as an attempt to interface with humanity.
Though in series it's ambiguous if they're really aliens or some sort of weapon or genetic accident. What is known is that they came from space.
Stripperific: Talho's clothes. Justified, and eventually replaced. How she dressed was actually a literary device to signify that she still refuses to accept her age. She did eventually replace her old clothes alongside with having an Important Haircut. Ever since that, she has become more of a mature Big Sis.
Super Fun Happy Thing of Doom: The "Summer of Love" was a worldwide catastrophe that was only stopped by the sacrificial efforts of Adroc Thurston. It is feared the "Second Summer of Love" could well mean The End of the World as We Know It if it is allowed to happen. Eventually turns out the "Second Summer of Love" averts this.
The "Joy Division". The use of the name is rather recursively appropriate, as the band picked that name as a reference to the 1955 novel The House of Dolls, where the Joy Division was the name for the prostitution wing of a Nazi Concentration camp — and the Joy Division is in a devastated city named Warsaw.
Transforming Mecha: Since the mechs in this series achieve flight by riding waves of energy in the sky they have no control over, almost all of them are capable of transforming into wheeled vehicle modes for land transportation where the waves are too weak to support them. A lucky few still have usable weapons in this state, most prominently Holland's Terminus typeR909. The Nirvash Spec2 can even step up the game by turning into a fighter jet! The only humanoid mechs which don't seem able to transform are the TheEND, the Devilfish, and the Beams's Spearhead SH-101's.and the Nirvash Spec3.
Wave Motion Gun: The ultimate attack of the Nirvash typeZERO Spec3, which takes out a virtual wall of Antibody Coralians with one shot. It's not that it looked like the Buster Beam. That thing was the Buster Beam.
What Measure Is a Non-Human?: Eureka, because she's a humanoid Coralian. She has emotions, thoughts, and the anatomy of a human, but she is a Coralian. Anemone as well, because she was a human who was genetically modified into a Coralian.
You Have Outlived Your Usefulness: Anemone comes to this conclusion about herself after Dewey tells her his ultimate plans. She still willingly participates in Dewey's final operation, but at that point she has the mindset that she doesn't care if she doesn't come back alive.
