- Eva came out and was a Deconstruction to the Giant Robot genre. A few years later GaoGaiGar came out playing everything straight as a Reconstruction. Now Madoka came out as a Deconstruction to the Magical Girl Genre and a few years after that Vividred came out playing everything straight.
- While an interesting theory, there is no way for viewers to prove this.
- Despite the utopic state of the world due to the energy provided by the Manifestation Engine, the Time Lords are aware that humanity could use said energy to make huge leaps in technology, up to and including Time Travel and making weapons that could obliterate planets. Indeed, Kenjirou succeeded in using the Manifestation Engine to create the keys to the Vivid System. Realizing that this could be a threat to their position as Time Police and the stability of the universe as a whole, they decide to test the responsibility of humanity by covertly creating and sending the Alone to attack the Earth. This is so they can evaluate whether or not humanity destroys itself through the infighting caused by such a crisis, or actually bands together to deal with it on a united front. Since no one else knows that the Alone come from the Time Lords, the latter can therefore use the former as a convenient way to put Humanity on Trial whilst still maintaining their de jure position on not interfering with the affairs of other planets and races.
- Within the context of the series and its backstory, Rei's world is therefore a parallel world to Earth with its own Manifestation Engine (or some equivalent of it) which failed the test and was obliterated by the Alone, leaving her as the only survivor. Taking pity on Rei and her plight, the Doctor proposed to the Time Lords to reverse their decision to destroy Rei's world, if it can be proven that there is at least one world which can pass the test. Knowing from personal experience, how capable humans on Earth are in banding together in times of crisis, the Doctor proposes to the Time Lords that Earth be the next world slated for such a test. Intrigued by the Doctor's confidence in Earth's people, the Time Lords agree to this proposition, and the Doctor sends the Crow as a messenger to both empower Rei and use her as a conduit to summon the Alone to Earth for the test. The Doctor also traveled in time to seven years before the series to given Kenjirou a message and warning that the Alone would come to Earth to test humanity. However, sensing that the Crow desired more than simply to be the Doctor's servant and messenger, the Master decides to tempt the Crow into seizing power for itself and may have given it the idea to devour Rei and absorb her arrows. The Master's influence therefore led to the Crow becoming Drunk on the Dark Side and an Omnicidal Maniac. For the Master, this is a way to Troll and spite the Doctor and deal a Kick the Dog to both Rei and the Earth, since if the Crow succeeds, Earth, the Doctor's precious planet, would be destroyed. And if the Master's ploy failed, s/he really couldn't care either way. Since Akane and Rei managed to destroy the Crow and end its threat despite the Master's interference making the test much tougher than it would normally be, the Time Lords deem that humanity passed the test and honor their deal with the Doctor by restoring Rei's world into existence, and may also have cleaned up the damage (and reversed any deaths) caused by the Alone to Earth's infrastructure off-screen. Noting Rei's role in averting Earth's destruction and feeling pity on her for the pain she experienced at the hands of the Crow due to the Master's influence (which he was indirectly responsible for), the Doctor may have decided to grant her a happy ending by providing her with a way to travel to Earth again from her world, allowing Akane to see her in the last episode.
- The "supreme beings who rule over all of time and space in all dimensions" that the Crow mentioned in Episode 11 are therefore the Time Lords. As the Crow was Drunk On Power and decided to go renegade by acting on its own accord, independently from the directive of the "supreme beings", anything it says should be taken with a grain of salt, including its claims that it destroyed other worlds before the start of the series, that Rei has to avoid contact with other people, and that she would die if she exhausted all of her arrows.

- Rei's arrows may power up the Alones, but they also disrupt they're ability to regenerate. The Alone fought and destroyed in the beginning of episode 4 hadn't turned red and regenerated and was fought again later in the episode. When it was destroyed for good, Rei had used one of her arrows on it.
- She's fully supporting the Alone.
- The soul of Akane's mom (Isshiki Mashiro) is trapped inside the Manifestation Engine, and Rei is her agent who she tasked to set her free. Rei is a piece of Mashiro's soul that is manifested using the energy the engine provides, that's why she's able to empower the Alone— she's similar to Akane in having direct soul connection to the Engine.
- Jossed.
- Another possibility is that the Manifestation Engine is somehow incredibly harmful in ways that Earth's populace hasn't noticed yet. After all, a machine that's capable of generating vast amounts of what is effectively free energy with absolutely no drawbacks sounds way too good to be true.
- While there is no proof it was intentional the incident when the Manifestation Engine overloaded did destroy where ever it was that Rei used to live.
- Rei couldn't care less about conquering Earth. She helps the Alone because a shady being promised her that it would resurrect her dead parents if she did. We still don't know why the Alone want to destroy the Manifestation Engine, tho.
- a second Manifestation Engine being built.
- the Manifestation Engine being upgraded.
- Turns out the alone actually draw their power from the Manifestation Engine.
- Jossed for the crow (god?) that gave Rei her powers.
- Confirmed in episode five, Rei has seven arrows left.
- Jossed for the part where the parallel dimension is where the Alone live.
- Jossed completely. The attacks on the Manifestation Engine are done to test mankind, not some form of self-defense.
- Jossed, Crow and the Alone want the engine destroyed.
- She's a Nanomachine colony. When someone docks with her, they are literally docking with her; her nanites surrounding them like a Bio Powered Armor and forming VividColor. Which would explain why VividColor speaks using Akane's voice.
- She will be the one that makes VividRed possible.
A possible variation for this guess would be that, if Rei does a Heel–Face Turn, she will also be part of VividRed.
- And now, the teasers show that Episode 6 is titled "The Story of How Kenjiro tries to intensify the friendship power of Akane and friends, which results in something unbelievable". Will that something unbelievable be Vividred? The answer...
- ...Turns out not to be as expected.
- If you didn't realize the long title was clearly a joke...
- ...Turns out not to be as expected.
- Well, the twelfth and final episode will be titled Vividred Operation. If this WMG is not confirmed at that time...
- Jossed. It didn't happen.
- Don't be that pessimistic. The end almost literally screams for a 2nd season.
- This is supported currently by Episode 5's preview narrated by Rei and the Episode is titled "Another Key".
- Which turned out to be an entirely different key. Vividblack is till just as likely as it ever was.
- Jossed. Turns out that the fusion between Akane and Rei is VividRed.
- Well, Rei herself cannot fuse with the Alone, it seems, but the Alone can definitely fuse with Rei, so... Confirmed?
- They're not prepubescent, did you see their boobs?!
- Jossed.
- Neither confirmed nor jossed. The only penalty we are aware of is that Rei's parents will not be brought back to life if she runs out of arrows. No word yet on if she too will die.
- Confirmed, somewhat, in episode 10. The crow reminds Rei that she'll disappear if she runs out of arrows.
- Jossed for the bit about being powered by her life force. The arrows are actually from The Crow. The reason she would disappear is that because she ran out of arrows she would have failed to fulfill her end of the contract.
- The Alone will complete its end of the contract and rebuild Rei's world and bring back her parents
- Akane and co. will then defeat the Alone before it destroys their world.
- Rei will double cross the Alone and destroy it (with or without helping/help from Akane and co.) before it destroys their world and then befriend them.
- The Alone will not follow through with the contract and instead tries to destroy this world too. Rei will begin fighting along side Akane and co. to defeat the Alone and become friends with them.
- This theory is confirmed for the most part. The Alone never had any intention of following their part of the contract.
- Jossed. Despite what the Crow says, the "supreme beings" it serves actually do restore Rei's world and leave Earth in peace, suggesting that the Crow went renegade and decided to destroy the Earth all on its own, against the will of the "supreme beings".
- There is no proof that the Alone caused the first meltdown. We only have an unusual floating red ribbon of energy to suggest it was sabotage, and even that doesn't suggest it was an Alone.
- Episode 10 pretty much confirmed that it was an Alone, and that it wanted to destroy the Manifestation Engine.
- Kenjirou states that the red ribbon wished to test humanity to see if we are worthy of using the power the Manifestation Engine produces, which has the ability to control the universe.
- However, the Crow reveals in Episode 11 that it was going to destroy their universe anyways, and straight up tells Rei that it never intended to restore her world.
- Jossed. Rei is a human girl from a universe that was destroyed by Manifestation Energy.
- Episode 8. Strong Parallels to Eva? Check. Injured character? Check. Vague psychoanalysis? Check!
- Possibly Jossed. The Alones most likely wanted to keep Rei in school because she was acting as beacon, meaning as long as she stayed near the Manifestation Engine they could find it.
- Jossed. In Episode 11, the crow, which represents the Alone, outright states that only the Alone deserve possessing Manifestation Energy and never had any intention of restoring Rei's world. The Alone are a bunch of arrogant jerkasses.
- Still possible as Akane and co were the first to ever pass the test. The Crow wants to destroy the world anyways, regardless of their passing, how the Alone, The Crow's boss, feels on the matter has yet to be soon.
- Confirmed. The Alone do in fact rebuild Rei's world.
...is not Rei.
It's her Alternate Universe counterpart (with a different name, which is why the authorities didn't know about her when they captured Rei). To keep with the Homura Expy theme, not!Rei will be shown to wear glasses.
Season 2 will also have Akane's counterpart from Rei's universe. She's...bitter.
Kenjiro didn't design Vividred, and he was just as surprised as anyone else when it appeared. Also, according to the Crow, Vividred was using an entirely new energy source, different from and superior to the one used by the Incarnation engine or the Crow herself. Akane took advantage of some of Kenjiro's technology in docking to create Vividred, but Rei had no key, and much of what happened transcended his technology. It can only be because Akane truly is a magical girl.
- So why not Rei being the magical girl, instead? Rei never shows any transcendant abilities in the show, whereas Akane transcends human norms constantly.
