[[caption-width-right:350:Have you seen the rest of me?]]
An astronomer in a Japanese observatory, peering into his telescope one night, becomes the first person to witness a planet emerging from a wormhole. He names the planet after his daughter, Remina, and both become world-famous thanks to the unprecedented discovery. However, things take a turn for the worse when the planet enters a collision course with Earth... [[TheStarsAreGoingOut and the stars along the way]] [[PlanetEater seem to be disappearing...]]

A single-volume manga by Creator/JunjiIto. Like the rest of his works, it's filled to the brim with plenty of BodyHorror, {{Eldritch Abomination}}s, and general horror.

!!This manga contains examples of:

* AbsurdlySpaciousSewer: Mostly averted. It's tall enough to walk in but there's only enough width to walk single file down it.
* AirJousting: Once Planet Remina licks the Earth and makes the planet spin out of control, it's [[spoiler:Remina and The Hobo]] vs. [[spoiler:most of humankind]].
* AlienLandmass: The surface of planet Remina is a hellscape full of toxic gasses and fog, intestine-like tubes, and "trees" which look more like writhing balls of tentacles. Nearly all of it black as midnight.
* AnAesop: Surprisingly enough for a Creator/JunjiIto story, it ends with a clear and uplifting one. [[spoiler:No matter how badly things have gone, no matter how bleak the future seems, so long as you are still alive there is hope for something better.]]
* ApocalypseHow: [[spoiler:Physical Annihilation of the Solar System by PlanetEater, to be exact. Given that stars go out in Planet Remina's wake, it presumably dishes out Stellar-class apocalypses casually.]] In fact the manga shows just ''how'' it gets there. The breakdown of society early on is merely icing on the cake.
* ArtisticLicensePhysics: At one point, the earth is spun around so fast that the stars blur in the sky like the hyperspace lines in Star Wars. Aside from everyone not instantly dying from this, there is even a scene where a huge group of people are able to use the centrifugal force to fly through the air ''all the way around the earth and back'', and some of them even survive falling back to the ground. If the rest of the earth moves with you, you're not going to die from a little spinning. But if only the earth is spinning, and the air isn't, then...
* AssholeVictim: Just about everyone who dies, mostly by virtue of joining the Remina murdermob shortly before their demise. Also, the cabal of corrupt government officials and rich fatcats who try to escape to Planet Remina and, unsurprisingly, meet horrific ends.
* AssInALionSkin: Played deadly serious. [[spoiler:One of Planet Remina's tongues inserts itself into a discarded spacesuit to lure in the Mineichi family and make them let their guard down so it can devour them. It's likely the humanoid figures from the probe footage were actually a similar trick.]]
* TheAssimilator: [[spoiler:Any human (and presumably anything else organic) that becomes exposed to Planet Remina's toxic atmosphere will [[BodyHorror melt horrifically in a matter of seconds]], then mutate to become part of the millions of fleshy growths adorning the surface of the planet.]]
* AttemptedRape: [[spoiler:Mineichi's son shows Remina]] the airtight room, claiming she'll be protected in there...and then tries to rape her. When she fights him off, he claims she came on to him, and Remina is thrown back to the mob.
%%* BadassBystander: The Hobo. Oh so, so much.
* BigDamnHeroes: Goda gets a moment of this when he [[spoiler:saves Remina in the midst of ''missiles and an earthquake.'']] Then MoodWhiplash kicks in again.
* BilingualBonus: As people from across the whole world are involved in the AirJousting sequence against Remina and the Hobo, several of them yell at our heroes in numerous foreign languages.
* BittersweetEnding: Technically a [[DownerEnding downer]], but it's strangely uplifting...
** It's uplifting because [[RayOfHopeEnding there's still]] ''[[RayOfHopeEnding hope]]''. They're still alive, which means there's at least a chance for a better future, even if it would take a miracle.
%%* BodyHorror: ''Don't'' take your helmet off on Planet Remina...
* BrokenBird: Remina falls a bit into this, especially after [[spoiler:the death of her father.]]
%%* BurnTheWitch: One of the many attempts to kill Remina.
* ButWhatAboutTheAstronauts: Inverted. The bases on Mars and the Moon are the first to go. The astronauts that landed on Planet Remina and the VIP's that followed them there also suffer horrific fates
* ChekhovsGun: [[spoiler:The bomb shelter. It ultimately allows the last survivors to escape Planet Remina's gluttonous maw.]]
* ChekhovsGunman: [[spoiler:The Mineichi family's long-lost elder son, now a hobo.]]
* ClothingDamage: By the end of the story, Remina has ''just'' enough of her dress left to cover all the important bits.
* ContrivedCoincidence: [[spoiler:Remina meets up with a hobo, who just happens to be the Mineichis' long-lost son, whose family also just happens to have some sort of bomb shelter in their basement which ends up saving Remina, the hobo, and a few others.]]
* CorruptCorporateExecutive: Mineichi. He's happy to sponsor Remina to boost his popularity, but he's just as happy to [[spoiler:turn her over to an angry mob once associating with her threatens him.]]
* CosmicHorrorStory: Without doubt. [[spoiler:Although the ending ultimately defies the usual message of cosmic horror -- human life is indeed important, because with it comes hope, the potential for things to be better.]]
* CrucifiedHeroShot: Remina, her father and the hobo are all tied to a cross so they can be sacrificed. [[spoiler:The angry mob stabs her father with spears, and then lights them on fire.]]
* DeadlineNews: An anchorman is reporting on the situation with Planet Remina and the riots all over the world. Just after mentioning that an angry mob is hunting down Remina, he is attacked by two MalevolentMaskedMen.
--> '''Cultist''': [[AC: [[WeInterruptThisProgram We interrupt this broadcast]] to bring you a message. We represent a concerned group of citizens who love Mother Earth. [...] There remains but one way to save the earth. Find Professor Oguro and his daughter Remina. Destroy them.]]
* DeathWorld: The planet's surface, a toxic jungle of [[WhenTreesAttack aggressive alien flora]], a horrifically caustic atmosphere, and [[HumanoidAbomination strange figures]] looming out of the fog...
* {{Determinator}}: The Hobo. No matter how bleak things may seem, he never gives up.
** The lead cultist is a villainous example. He is ready to go round the world to hunt Remina down, and he never, ever, ever stops. [[spoiler:Of course, there's a reason for this...]]
%%* DirtyCoward: Kunihiro Mineichi.
* DramaticUnmask: At one point, the head cultist's whip accidentally wraps around his hood and rips it off, revealing him to be... [[spoiler:a resentful Goda, former president of Remina's fanclub.]]
* EldritchAbomination: The titular Remina is a planet-sized devourer of worlds rather than an actual planet.
* ExplosiveDecompression: [[spoiler:From the ''inside out,'' for the poor human survivors who got attacked on Planet Remina by the crewmember they purposely let die. Or they had all their internal organs crushed by the tentacle. Either way, it was painful.]]
* {{Expy}}: The Planet Remina is ''extremely'' similar to Ghroth, an Outer God of the Cthulhu Mythos.
* {{Foreshadowing}}: The lead cultist is seemingly quite angered by Remina embracing the hobo. [[spoiler: This is because he is Goda, and is still as possessive of Remina as before, just driven homicidal by rejection.]]
* GeniusLoci: The titular Remina is a planet... well, actually more like an EldritchAbomination the size of a planet.
* GoMadFromTheRevelation: Ikeuchi the astronomer, once he realizes just what Planet Remina is.
--> '''Ikeuchi:''' MY EYES MET WITH REMINA'S!
* GuiltByAssociation: The mob will also kill anyone who's with Remina. However, if that person turns against Remina (like Kunihiro), the mob immediately accepts them or otherwise leave them be. But if that person wants ''nothing'' to do with the craziness (like the bum initially), the mob will try to kill the person anyway.
* GuiltByCoincidence: Remina, who was born on the same day the planet emerged from the wormhole. This leads the public to believe she and her father are responsible for its appearance. It's implied that this is caused by hysteria and desperation rather than any genuine belief though.
* HeroicSacrifice: [[spoiler:Yasumi does this by taking a knife in the back for Remina.]]
* HowWeGotHere: The manga begins with Remina tied to a cross, surrounded by a huge crowd and a couple of [[MalevolentMaskedMen shadowy figures]] who want to kill her, while two monstrous eyes watch the scene from the sky.
* HumansAreBastards: For the most part, anyway. Panicking at the thought of the coming apocalypse, the populace direct their anger towards Remina and her father, [[spoiler:brutally murdering the latter and chasing the former around the earth.]]
** Perhaps somewhat justified in that the angry masses were being egged on by the cultists, but otherwise yes - this trope is played fairly straight.
--> '''Bum:''' They get you, they don't, don't mean a thing to them. They'd never stop with you now that they got a taste for it.
** Said Hobo's point becomes even more poignant when it's also pointed out that sooner or later, everyone would turn on each other in the vain hope of sparing their own skin.
* InformedAbility: Remina (the person) becomes famous because of her association with Planet Remina. She (reluctantly) uses the fame to become a famous idol. It's never made clear what she ''does'' beyond standing on a stage/in front of cameras and looking pretty. It's possible people are paying to see precisely that, making her career AnAesop about the insanity of fandom, or something.
* InsaneTrollLogic: People have somehow come up with the idea that sacrificing a girl named Remina will appease an entity that, from a point before being named the same, has already been roaming the galaxy consuming planets and stars.
* IWantMyBelovedToBeHappy: Goda claims he'll save Remina's life, even if she loved Yasumi instead. [[spoiler:[[IfICantHaveYou He's lying.]]]]
** [[spoiler:It's possible that he meant it at the time that he said it, only to change his mind later when he comes to believe that Remina hates him.]]
* JerkAss: Kunihiro, who is clearly only tolerated by Remina and her friends because [[SpoiledBrat he's got the resources to help them out]]. [[spoiler:Until the attempted rape, anyway]].
* LecherousLicking: While Planet Remina "licks" the surface of Earth with its tongue, the main cultist does the same to Remina's face, with a tongue that's weirdly similar to the planet's own.
* LeftHanging: As is common in both [[CosmicHorrorStory Cosmic Horror Stories]] and Junji Ito's, [[spoiler:whatever the hell Planet Remina was is never revealed. Nor is, for that matter, the identity of the first three cultists who wanted to sacrifice Remina, or why Goda had a tongue similar to Planet Remina's when he was dressed as a cultist.]]
* LegacyCharacter: It's actually two separate people who take on the role of the masked leader of the cultists, first being unknown, and the second one being [[spoiler: Goda]].
* MacrossMissileMassacre / NukeEm: The military fires a few dozen nuclear warheads at Planet Remina's tongue. [[spoiler:They bounce off and return to the sender.]]
* MalevolentMaskedMen: The [[http://www.mangafox.com/manga/hellstar_remina/v01/c002/34.html cultists]], with their {{black cloak}}s and [[InTheHood hoods]] similar to those of the Ku Klux Klan.
* MoreTeethThanTheOsmondFamily: Planet Remina. [[http://1.bp.blogspot.com/-aKqXuhSdhsc/UIDPSWyFx_I/AAAAAAAAAo0/oXSqbitAdug/s1600/Hellstar+36.jpg Behold the horror.]]
* NegativeSpaceWedgie: Planet Remina came to our region of space through a wormhole, therefore proving the phenomenon's existence. Not that such a breakthrough in astrophysics actually helps anyone, considering the fact that they didn't have a chance to record or study the phenomenon...
* NeutralFemale: Remina does little to nothing to protect herself or defend her own life. The male character she happens to be following at the time is the one making all of the plans and doing the work to keep them both alive, with her simply being led by the hand except on rare occasions.
* NoBiochemicalBarriers: ''Completely averted''. Whatever passes for an atmosphere on Planet Remina's surface is incredibly toxic and acidic, and horribly melts a dying refugee the others use to test the air.
* NotSoDifferent: Notice how the head cultist's mask has vertical eye slits all too similar to Planet Remina's... not to mention his tongue. He's also a complete sadist who wants to see Remina suffer as much as possible, not unlike the planet itself does to Earth.
* OhCrap: The astronomers' reaction every time Planet Remina eats something.
* OnlySaneMan: The Hobo soon becomes one of the few ''sane'' people left, who also happens to be remarkably intelligent and aware about the whole situation. [[spoiler:He's revealed to be the elder Mineichi son, aka the one who sought to become an astronaut.]]
* OnlyTheLeadsGetAHappyEnding: Probably one of the most extreme examples out there.
* OurWormholesAreDifferent: Planet Remina came from AnotherDimension through one of them. And if the title [[HellGate is an actual description...]]
* PlanetEater: Obviously.
* PlotArmor: The entire human race gets spun into the stratosphere (literally), and all of them are out to kill Remina and the Hobo. The latter two manage to land unharmed on the ''numerous'' corpses of their pursuers.
* TheReveal: The tenacious cultist is [[spoiler:Goda, the president of Remina's fan club]], and the hobo is [[spoiler:the older Mineichi brother.]]
* RedHerring: It's implied that one of the astronauts that land on Planet Remina is the long-lost son of the Mineiachi family, who dreamed of becoming a astronaut and ran away from home after his father forbade it. [[spoiler:He's not, the son is actually The Hobo]]
* SanitySlippage: An increasingly large fraction of humanity undergoes this as Planet Remina moves ever closer to Earth. Soon enough, the only sane people left alive apart from Remina are a handful of bystanders [[spoiler:and the elder Mineichi son]]. [[spoiler:They also become the sole surviving members of the human race in the end.]]
* SciFiWritersHaveNoSenseOfScale: How does a Jupiter-sized ''organism'' form and not crush itself from its own gravity? There's a reason solid planets don't form that large--they would destroy themselves from their own gravity. [[http://mangafox.me/manga/hellstar_remina/v01/c001/30.html Even though it's actually nowhere near Jupiter size.]] Further, how does the Hellstar travel faster than light, let alone do so without killing itself? How does it withstand the vacuum of space, especially it's gigantic, sensitive eye, or its tongue? Lastly, how does it eat a planet like Earth or ''Jupiter'' without killing itself from the extreme heat, pressures, gasses and solids, radioactive material, and everything else from what it eats? All those questions were asked inside the story by the scientists who discovered and observed it. ''Nobody knows''. They did say it was from another universe, maybe it operates by different physics. [[HellGate Or...y'know...]]
* ScrewThisImOuttaHere: While society at large crumbles, the government and what's left of civilization attempt to jump ship for Planet Remina hoping to rebuild there. [[spoiler:It goes as well as you'd expect.]]
* SealedRoomInTheMiddleOfNowhere: [[spoiler:once Planet Remina eats the earth, the only survivors are trapped in an airtight fallout shelter drifting through the now-empty solar system. They have enough supplies to last a year.]]
* ShoutOut: [[http://www.mangafox.com/manga/hellstar_remina/v01/c002/2.html That's]] [[Franchise/StarWars no moon!]]
* SoBeautifulItsACurse: The ''other'' cause of poor Remina's many problems.
%%* TakingTheBullet: [[spoiler:Yasumi]] to [[spoiler:Remina.]]
%%* ThatsNoMoon: See ShoutOut, above.
* TheBadGuyWins: [[spoiler:Planet Remina successfully devours the earth.]]
* TheStarsAreGoingOut: The first clue about Planet Remina's true nature is when astronomers notice that the surrounding stars "disappear".
* TorchesAndPitchforks: And knives and fire axes and the occasional gun.
* TwentyMinutesIntoTheFuture: The story takes place in "July 20XX".
* WhipItGood: The head cultist's weapon of choice.
* WholePlotReference: To ''Literature/WhenWorldsCollide'', although in this case the giant planet about to destroy Earth and the planet that the rocket ships plan to escape to are one and the same.
* WhyDontYouJustShootHim: The cultists have many, many occasions to kill Remina, but never actually get around to it. Somewhat justified since, being batshit crazy cultists, they want to make her demise a ritualistic sacrifice during which she has to go through as much suffering as she supposedly brought to the people of Earth. It's also likely they would have torn her apart were it not for the cultist acting as their leader to insist that Remina has to die via "ritual," likely just to prolong her agony.
* WitchHunt: Invoked by the [[spoiler:cultists and mob when Remina is tossed outside by Kunihiro.]]
** Somehow justified. By that point, what's left of humanity has generally become so desperate and far gone that they're willing to do ''anything'' to put an end to their misery.
%%* {{Yandere}}: [[spoiler:Goda.]]
* {{Zeerust}}: The architecture and technology appear to have come straight out of the '60's-'70's era sci-fi. It even includes a RetroRocket [[http://mangafox.me/manga/hellstar_remina/v01/c004/35.html (here)]] as a means to evacuate [=VIP=]s from Earth.
