Okay, so one other thing I haven't mentioned is that... There is actually one more protagonist from Madoka Magica that I haven't spoke of much yet, besides the one from Null Magical Girl. I actually mentioned her, but weren't really, really gonna have her around because... Reasons.
So let me tell you a bit of Scene 0, the story of Mabayu Aki.
Scene 0 was conceived as a story about a cinephile NEET girl with no friends who upon watching some movies, finds out that she's been stuck in a time loop as she finds out previous timelines have been recorded as films and she watches them trying yo figure out what to do. It wasn't originally tied to the franchise, until someone suggested to make it a Madoka Magica project.
Thus Scene 0 was reworked to not only be part of the Madoka Magica franchise, but also a prequel to the main anime... Sort of. Mabayu Aki is a magical girl who forgot how she became one and feels the circumstances were really really really important, so she tries to solve the mysteries of why, and it's revealed that she was always there as Homura traveled through time, becoming basically her own Homura as she went on to try to assist her in saving Madoka.
And the whole previous timelines being recorded into films was explained to be a result of her magic.
And of course, this is Madoka Magica, and unlike Homura who must survive every timeline to do her resets... Mabayu doesn't has as much plot armor so she sees herself die more than once. It ain't pretty for her but she simps for Homura bad so she tries to keep on.
Long story short is that the reason she was forgotten and she herself forgot everything was because Homura as stoic and cold as she was to her, was legitimately getting attached to Mabayu, but Mabayu realized that was instead interfering in the goal of saving Madoka plus coupled with the lots of angst she was suffering herself, she decides to make everyone including herself forget she was part of the group.
So yeah it's a story with a bittersweet and kinda rushed ending which is... Kinda the standard actually. But hey, those that have experienced the story liked Mabayu.
Now you'd think the next logical step would be to think this was published in the form of a light novel or a manga... But not really, it was instead made an event in Magia Record, which is weird, because Scene 0 is not connected to absolutely anything else in Magia Record, and it was also one of the very last events of the game before it shut down.
But I guess official channels at least have bothered to upload the stuff in video platforms to preserve it. Plus Mabayu is confirmed to appear in the next mobile game, so... Yeah.
-What she thinks of Oriko's inner GAMER RAGE?-
---
Kazumi: "Aw please, stop it!"

---
Homura: "O-Okay..."
---
Suzune: "If I wasn't as sure as I am that we can't become Witches anymore, I would have killed the others and then myself..."
---
Brynhildr: "Oh, that so? So do some others here, but less than other weapons..."
Unreplied Uni
Susie: "A-Alright! Let's uh, flip the coin then."

___
-He's looking around to see if there's any new visitors or members here...Or to see if any of his old skeleton minions are here to visit him- :V
___
They've also made considerably more allies since the last time we dealt with them. And given their own capabilities, we've had to account for that and adjust our strategies accordingly...
___
-People being genuinely worried about her well-being despite everything she's done?-
___
-All of those Pokemon..
.her Pokemon...suffered horrifically, for no reason...-
-The Aces wait for the result!-
---
-That would be sweet, but instead he'd see a bunch of normal-looking teenage girls conversing-
---
Shockwave: "It was our mistake to understimate their forces last time, so never again"
-Tarn and Deathsaurus are considering what they're being told now...-
---
-Yeah, Suzune didn't expect the people here to be this open...-
---
-Many would just blame the Nihilego that fused with her, but she's not sure about it... She believes she is at fault too-
(He got turned into a werewolf?! That's just like what happened to Shirou a while ago...)
-Isn't close to Shirou, but has a great amount of respect for him since he's her Trainer's son and because he's a genuinely kind person along with that-
S-Sorry, Lady Palutena, b-but I can't honestly disagree. 
-Palutena annoyed that even Lindy is getting in on the joke?-
___
Dipper: "And...why?"
-They can even see griffins, flying mouths, and witches riding on staves flying throughout the sky above the islands formed by the giant monster corpse, making it clear that this is the very same realm they glimpsed from that basilisk's memories-
___
Peridot:
(Huh, briefly being startled by hearing someone else's voice in my head aside, what an awesome power! And here I thought we only knew people who were capable of telepathy by forming magical contracts!)
Lapis:
(I'll head back down, too. I can't see any clear any of monsters nearby.)
___
-Hekapoo then forms to fireballs in hands, and launches them at Sothis before darting towards her at extremely high speed-
-The fireballs prove surprisingly strong and travel almost as quickly as Hekapoo herself can run-
// I forgot Puppy Sherou...
Kamui: "Well, I'm glad the kids are entertained."
Palutena: "...Could you please stop?" >_<
---
Byleth: "Those five girls have fought me. And are likely clever enough to realize another encounter is likely. It gives them and Epimenides a common foe. One that would prevent either of their goals from being achieved by that foe's very existence."
Azura: "And what does this Epimenides character seek to achieve?"
Byleth: "Kill Sothis."
---
Zelda:
It's also an ability I've had ever since my powers first awakened, Peridot. It was quite practical in terms of informing Link while I struggled against the Calamity.
---
Viridi: "I NEVER SAID THAT! WHAT I SAID IS THAT HE'S AN IDIOT!"
Queen Medusa: "Oh please, even I can see it, and I don't even care about you."
Viridi: "Shut up, snake!"
Pandora: "Nah. However pretty she may be does not match my divine perfection~"
-Sothis quickly stops time, not to move for easy avoidance (she doesn't plan to move an inch) but to figure out a course of action-
Sothis:
Hm, of course. -casts a barrier around herself which, unlike the one that grants invincibility, instead "only" grants strong resistance to magical attacks which gradually weakens over time-
This should be a fair counter. -resumes time-
-I would imagine only Omnitraxius could sense she stopped time, so Hekapoo would not realize it?-
//I also forgot that
Nanoha: "Awwww, I really hope he gets cured of that..."
Merlin: "...Hmmm, maybe not"

---
Iroha: "...That's all his goal?"
Suzune: "You understimate how drivencan someone be just to kill one person"
Oriko: "Indeed, I know that well"
Homura: "this... this is really bad..."
Tart: "Calm down, are we certain of this?"
Kazumi: "Yeah, like, can someone else detect him?"
Kagari: "Hmmm, this is definitely the same realm"
Kanna: "I see, so we might be able to recruit some for our cause... By force"
Sasa: "Just say who! I'm already eager seeing all the stuff like the griffins!"
Alina: "Indeed~ Aaah, I already have so many new artworks in mind~"
-Minou placed a hand over her chest and held a deep breath in relief that this realm doesn't has the overwhelming energy that modern day settlements have-
---
Iroha:
Huh... I thought it would be common in other places -she's returning now-
---
Euryale/Stheno: "What's wrong with snakes, huh?"
-Yep, that sounds so much like Goldmary, eh Alear?-
-Would Hekapoo?-
