As a creator of my own series, this specific show spoke to me on a different level. Re: Creators is a series that tackles the subject of: What if all of your imagined characters and creations actually ENTERED the REAL world! This series made me feel a bit complicated… but greatful at the same time.

At first, Sota is a boy that lives at home, but then is suddenly thrusted into the world of one of his favorite series: Elemental Symphony of Vogalchevalier. An “Isekai-esk” series that involves both: Mecha and Magic. But once the villain of the seeming series makes her appearance, Sota is immediately thrusted back into his OWN world, only the main character of the series: Selesia came back with him. But not only that, but the villain came to the real world as well...!
Known at first as the: Military Uniform Princess, the villain simply brings fictional characters to what she believes is the "Land of the Gods" with the intended purpose saving "Saving the world", but as it later turns out with both her identity and more characters that she unleashes, her TRUE plot is far more destructive than just SAVING the world.

On first contact, the characters that appear all seem to follow a certain aesthetic of ACTUAL anime troops. From the main characters: Selesia, a representation of Isekai characters from tropey anime that have both Sci-Fi AND Fantasy in their worlds via: Mechas and Magic.

To the Mage: Meteora, who plays the original role of just a Librarian-esk "NPC" mush like in RPG games like DragonQuest and the like.

These characters are the first to make appearances in the real world, alongside the villain. The hero, Sota does a good job showing them around the real world of Japan as Selesia actually seems to not hold anything against him and even quickly realizes that her true enemy is the M.U. Princess that transported her in the first place.

As other creations come into the real world, it is apperent that Sota needs to get the ACTUAL CREATORS of the characters to join to together with him in order to think-up a plan to defeat the M.U. Princess! Just as all of the creations are exploring the real world for themselves and deciding on how the real world should and will affect their wills to go back into their original universes.
Mamika: The magical girl, is one such character who goes through a major arc, as at first, she thoughtlessly destroys buildings but then realizes that her actions TRULY have consequences! As she finds out more about how nasty the real world turns out to be, she sticks true to her intentions, and decides that her magic truly IS her source for defending her friends within her world, and showing that however unruly the real world is, someone can ALWAYS help to make it better...!

Although, I'm not exactly the biggest fan of her ultimate fate...! A she is actually the first one in the series to DIE by the villain's hand! Leaving her to a PAINFUL and struggling death! And though I can see that "Madoka Magica" is the probable source as to why such a cute, pretty, and pink girly girl has to die so gruesomely, that doesn't change that... I'm just not one for pure and pretty girls to get killed is all....

While all the creations are meeting their creators, Meteora comes to find out the poor fate of her own character, that they actually died some time ago in a car-crash. Meteora decides to play the full way through her creator's game and comes to realize just how much thought, effort, and energy went into creating her game. This is one of the first times that the notion of creating a story gets spoken about the efforts of how much that people sacrifice to bring their creations to life, as it puts a depressing face on how unlike some other characters are lucky enough to meet and speak to their own creators about their worlds, stories, and troubles... sometimes, life does take an unexpected turn, and take lives right before truly significant revelations can be met. But, how if you create a world that you have full faith in, the public will love it with all their on heart and will to praise it. Another character is: Alicetaria, who takes her own creator hostage, until she realizes from him that he is only WRITING the story, as only the CHARACTERS can live-out and TRULY accomplish their goals of ending their stories.
This actually speaks to me personally as I feel as a writing that my own characters accomplsh their duties, and that I'm rather the "God", writing their stories.

Other characters based on obvious homages also come into the story. Including: Yuya (Shaman King/JoJo-esk character),

As well as a Mecha character: Kanoya (homaged from any Mecha show)

Or the villainess anti-hero that plays more of a sinister role in the Creations, Magane (Inspired by seinen horror series)

But her role is mostly to toy with people's emotions unil she gets what she just wants.

Also, she is the only character to KILL her OWN creator!

With these characters that M.U. Princess sent to the "World of the Gods", obviously meaning the REAL WORLD where these characters' CREATORS exist. Even though it's VERY OBVIOUSLY after the first time you heard the term DOES GIVE aa very MYSTIC AND ELUSIVE feel to how the M.U. Princess perceives what she ACTUAL does KNOW IS THE REAL world...!

About half way through the series, we find out that the M.U. Princess is actually Sota's past friend's own creation, named: Altair. And that his friend has actually passed away sometime ago. Sota still feels responsible as he believes that he is part of "Pushing" her over to wanting her to kill herself due to not feeling able to stand by her side as she get a new Job as a Mangaka/Artist. And that since Altair's creator no longer exists, and the internet has taken over her "Creation", she can have presumably ANY POWER to make herself stronger (NARRATIVE-WISE)!

But once all of this is revealed and the original creators are gathered, the time comes for the final battle, as Meteora strategizes a plan to hold an Event with all of the characters to destroy Altair! Just as then, Altair ALSO decides to bring more characters, some whom come from the same universe as others, to keep fighting on her behave after she has already lost a few subordinance.
As there is officially organized a special manga spin-off and prequal series to create characters JUST to defeat Altair!

Although, I understood most of how the creators felt, creating series and attempting to have the characters have consequences for their actions JUST to keep the stories interesting, I can't say I understood that much of how Altair's powers of "Narrative" and existence WORKED exactly. As it just kept piling up JUST to keep the story going.
Although, how they defeat Altair is amazing...!

Creating a version of her real creator to to tell her to leave the real world REALLY was a nice and creative answer!

Although, I have a Nitpick:

• At the very ending of the series, when all the creations are going back to their own universes, Magane DOESN'T get sent back! True, Neither does Meteora, back SHE isn't a psychotic murderer like Magane is...! So what the hell!?

Although the opening song: GravityWall, IS still an awesome banger in its own right, with its Techno. beat to give the vision that digital creations are coming to life and entering OUR world: I'M SCREAMING SOMETHING TO YOU, WHATEVER SOMETHING TO ME!

The rest of the series is great, if not a little too complicated with the meta-talk, I personally give it a high rating, but that's only my opinion.

Meteora:

All you just need is passion and practice.
