Summary
In the second Loop of Re:Twintail (chapter 5) Subaru eventually meets her inevitable end to the beast of the end puck rampaging due to the death of Emilia.
But what if that wasn’t how the story went? What If Subaru realised she was looping early enough to save Emilia even all the way back in that second loop?
And what if she turned out to be a dragon candidate instead of Felt along the way? Tag along folks this ride is a wild one! ;) -

Summary
Subaru still has Return by Death.
The world is still cruel.
The loops still hurt.However, when he meets his first end...
“WHY THE HELL DID I BECOME A MAGICAL GIRL!?”
He wakes up not recognising himself, or rather, herself. Subaru finds an unremovable bracelet fused onto his wrist, and whenever it glows, he transforms into a girl far more capable than he ever was.
"Just what does Natsuki Subaru mean anymore..? What's he worth?"

Summary
This is the summary.
But honestly, can chaos truly be summarized?
When 31 authors have no idea what they're doing, a summary is a futile endeavor. A summary violates all of our rights.
Now, you walk into the chaos. Who knows what shall come out of it? Not even the creator can figure that out.
Until then, have some mayonnaise along the way.
Or, as the 31 authors would put it: Otto and Subaru hijinks. Chaos. Pure, delicious chaos.
(If you are author, this story needs your help to be saved. Please.)

A Tale of Twintails: Permenance IF by Cardinal_M

Summary
This idea has been tossing around in my head for ages now so I just had to put it on paper! An If route where Subaru gets isekaied already as the mahou shoujo tail black from the second he appears. He has to adapt to the world differently and all things considered, goes down a very different route in the end from either cannon or mainline twintail.
Like Never Isekaied IF this one getting continued is a littleeee conditional so be weary. But I do really like this idea so I'd Be hard pressed to just give it up entirely lol.
Notably this idea was both proposed, and made as a result of a deal with Elsa-Tan! She's a great writer and really fun to talk to if you see em around give em a wave. (˶ᵔ ᵕ ᵔ˶)

Summary
Now for a heads up this Route was just put together because I couldn't get the idea out of my head and really wanted to do at least one chapter of it. I dont know if it'll get continued but If I didn't at least try to make it work I'd feel wrong lol. I hope you have fun reading because I definitely had fun writing!

Summary
"HOW THE HELL DID I END UP BACK HERE!?" Long story short, Subaru went to bed one night and woke up back home. He had a few things on his to do list, namely checking on his parents or rather mustering the will power to even face them again, but that all had to be pushed to the side when a small red-haired girl showed up infront of him.
A oneshot where TailBlack gets reverse isekaied to earth.

A Tale of Twintails: Cut content/Pre-Rewrite Versions by Cardinal_M
Fandoms: Re:ゼロから始める異世界生活 | Re:Zero Starting Life in Another World (Anime)
10 Feb 2026

Summary
This fic is a special one! It's unique from the bonus content fic as it is specifically for scenes that got cut and were never cannonised. Such as prior drafts and that nature of thing. I dont want to flood the main bonus content fic with all this because really its just something I want to put here so people can see it. I'll probably be putting my pre re-write chapters here as well given time alongside the comments that were lost.
Since this fic is basically just for compilation sake I'm only going to update the publication date for cut drafts which contain unique content. Thus if you see this on the front page its safe to assume its not just the pre rehash/redux chapters.

"A simple motion makes the consequence intricate."
Natsuki Subaru goes for a walk earlier than normal.
Hatsune Miku takes a long, arduous tumble.
Kasane Teto is crushed by immense pressure.These three intersect and end up more thoroughly involved than they could have ever comprehended. How will they move forward? Can they? I hope so.
