[[WMG: Planet Remina is also a LotusEaterMachine]]
* We saw a person becoming part of the planet after being exposed to its atmosphere. We also know that this was not just a case of the unfortunate astronaut just being melted by the atmosphere and fertilizing the living matter already present on the planet, because his eyes and tongue did not melt: instead, they were changed in shape and size to the same monstrous proportions of the tongues and eyes that were already present on the surface.
** The ending wants us to believe that [[spoiler: when planet Remina ate the Earth, the Earth was not consumed like all the other planets; instead, it exploded, but somehow the nuclear shelter and its occupants survived unharmed, while planet Remina moved away from it and left the solar system. One of the occupants was also convinced that they would experience a miracle within a year, since their survival was already a miracle.]] How convenient.
** What if, instead, planet Remina does not consume sapient creatures, but turns them into parts of itself, feeding their brains with false perceptions? This would explain the transmission of Kaneishi from the planet (his words weren't just misinterpreted: he was actually perceiving Remina as a paradise), while the ending would not depend from a DeusExMachina: the people who think of themselves as survivors are actually on Remina and suffered the same fate as that astronaut: their tissues became parts of the planet, while their brains are merely perceiving that they escaped.
*** Alternatively, what if Remina wasn't trying to deceive ''anyone'' with Kaneishi's report? If the planet keeps its "prey" alive and conscious, providing for their every biological need, they may indeed see it as a paradise once they've had a chance to adjust. Imagine the towering black tendrils as palm trees, and Kaneishi's video feed could almost be a commercial for a tropical vacation spot.
** Remina's normal "food supply" might consist of lighter elements, perhaps to produce energy via nuclear fusion. That would explain why entire ''star systems'' disappear in its wake, and why it went straight for the gas giants when it reached Sol. The occasional rocky planet is probably good for growth, but not particularly tasty; Remina gulps down Mars and the Moon like vitamin pills. A world with life, on the other hand, would be an exceptionally rare treat.
[[WMG: Planet Remina is Human Remina after Time Traveling]]
* Eventually, i.e. after one year, Remina and the rest of the survivors would die off, but Remina would first be driven insane by the ordeal (especially once supplies got scarce and she was tortured through starvation and etc., might even resort to cannibalism just to survive a little longer); the safe room would crash into asteroids and other space debris, creating a core for a planetoid. Remina's insane mind would remain, however, and combined with extraterrestrial life eventually formed the basis that would one day become the planet Remina. Because of the starvation she suffered through, as well as her desire to return to normal/life, Planet!Remina went about devouring worlds, gaining mass in the process. Then the wandering planet traveled through a wormhole and after finding its way (say, telepathic connection with her past human self), [[BookEnds Planet!Remina returned to Earth]] and [[HereWeGoAgain started the whole thing again.]]
** If that's true, then the cultists were right in trying to kill Remina. [[LaughingMad Kehehe]]
** That doesn't explain why one of the Cultists has a similar tongue.
[[WMG: The Cultists Are Manifestations of Remina On the Earth]]
* We know Remina can have its "tongues" take on humanoid shape to trick and attract prey. The cultists are its way of screwing with the earthlings, as well as trying to kill off the only people it knows might survive.
[[WMG: Planet Remina can Manipulate Its Own Gravitational Field]]
* It can accelerate close to the speed of light (and possibly [[FasterThanLightTravel exceed it]]) without damaging itself, changing shape, or ejecting any of its mass into space. It's made of living tissue and has an atmosphere thin enough for humans to move around, yet it can force itself inside a gas giant without being crushed, and it never seems to change size despite consuming several large planets. It comes very, ''very'' close to Earth without disrupting its orbit, at least until it decides to swallow the planet. Its "tongue" manages to deflect a [[MacrossMissileMassacre salvo of ICBMs]] without setting them off... or perhaps Remina had its gravity "ignore" them, and they simply fell back to Earth.
[[WMG: The manga takes place in [[MayanDoomsday 2012]].]]
[[WMG: Planet Remina is a [[Franchise/CthulhuMythos servitor of Azathoth]].]]
* Based on this [[http://godofwarlover.deviantart.com/art/Remina-190053741 little story]].
[[WMG: The survivors found themselves on [[Franchise/TheHitchhikersGuideToTheGalaxy Magrathea]].]]
* The inhabitants remade the solar system, and [[HappyEnding the survivors resume their normal lives]].
[[WMG: Planet Remina is a [[Anime/PuellaMagiMadokaMagica magical girl turned witch]].]]
* Planet Remina is the witch form of a magical girl and after [[spoiler: Madoka's universe changing wish]], this whole event never happened.
[[WMG: Remina can mildly mutate people at a distance]]
* So direct contact with Remina's hostile atmosphere causes instant disintegration and mutation into a [[BodyHorror fleshy horror]]. Maybe if Remina is close enough to another planet with life, some isolated particles of Remina's atmosphere can occasionally reach and infect the atmosphere of the other planet, causing mild mutations. Like head cultist [[spoiler:Goda]]'s tongue.
[[WMG: Remina is not merely from Hell. Remina '''is''' Hell.]]
* Inspired by an idea on the YMMV page. The events of the manga are literally the biblical Apocalypse, and Planet Remina is Hell itself rising up to consume the sinners. In the end, Remina herself, the Hobo and their group of survivors have been deemed worthy to ascend into Heaven.
** Incidentally, the song [[https://www.youtube.com/watch?v=iR-16SX4Vv4 Planet Hell]] is pretty fitting for the events of the story...
[[WMG: ''Hellstar Remina'' was originally intended to be longer, and significantly different.]]
* This story just has a bizarre number of loose plot threads, and too much symbolism that never goes anywhere. Why ''did'' the planet show up on Remina's birthday and then make a new line straight for Earth? What did Remina do to get famous, and why a construction firm? Who was the original lead cultist, and why does he never show up again? Just what are those figures on Remina? There are a lot of potentially interesting physical parallels between people and the planet (including the lead cultist, and one scene where Remina's eyes look surprisingly like the planet's), but they never go anywhere. The hobo's astronomical knowledge is hinted at, but goes nowhere. Remina survives bizarre situations (including a nuclear blast shown to cook someone next to her, and a fall that killed almost literally everyone else. Every time she's about to be murdered, it seems like Remina ''intervenes''. All of it would make more sense if the story were originally longer before being curtailed due to a publishing schedule, or something along those lines.
-> If the construction company had been responsible for building colonies on Mars or the Moon, that would explain why they would want an astronomically themed spokesperson. It would also give them a reason to just have a shuttle lying around, which the brother would know how to fly after going to school to be an astronaut and flunking out, too ashamed to return to his family. They could land on the planet Remina, unaware of the fate of everyone else who went there and building tension through dramatic irony. Then, they could discover the true nature of the humanoid figures, creatures that were absorbed by the planet in the past and now want to put a stop to its warpath before it can destroy another world. Creatures that know Remina and the planet actually ''are''connected. That Remina really is calling the planet to the Earth, acting as a figure similar to Nyarlathotep as a projection of the Outer Gods. That she really can't be killed except in a ritual execution. Creatures that sent one of their own to lead the cult that tries to kill her. Remina becomes a planetary-scale version of Tomie. The hobo is just totally fucked after trying to do the right thing. It's a bizarre twist that makes more sense, and ties the story back into the themes usually used by Ito.
[[WMG: Remina is a descendant of Tomie]]
* The reason Remina got so popular so fast without any known talents besides her beauty is because she inherited Tomie's power of attraction, even though after some generations the power is reduced. However she also inherited the curse that makes everybody affected by her attraction try to kill her eventually. That's why most of the world tries to kill her despite the cults' idea being quite silly. The approach of the star only triggered their murder intent, it would happen anyway. However this power is also diluted, that's why her manager wasn't affected.
