Summary
Class is in session at Beacon Academy, and Team RWBY have just started their second semester, training to protect the world of Remnant from the Creatures of Grimm. But not all is as it seems. Shadowy groups are drawing up sinister plans, and it's up to Ruby, Weiss, Blake and Yang to investigate before things get out of hand.
Meanwhile, on the remote planet Rubicon 3, Augmented Human C4-621—callsign 'Raven'—and Ayre witness Coral Release. But instead of symbiosis, 621 and Ayre are whisked away from Rubicon and split apart from each other against their will.
Forced to take separate paths, 621 and Ayre now find themselves on Remnant. Ayre winds up in Vale, and runs into a startled Team RWBY in the middle of a firefight. And 621 crash-lands into Mistral, where she—and her thirteen meter tall war machine—falls in with bandit leader Raven Branwen.
Between superhuman Huntsmen, the Grimm, and Remnant's eclectic inhabitants, 621 and Ayre struggle to reunite. Even as their very presence sets Remnant on a course of events that no one can predict...

Summary
When she arrived on Rubicon, she was nothing more than a tool. Devoid of purpose and identity, empty of hope and dreams - the perfect soldier, until an accident during a mission awakened parts of her that should have remained dormant. Guided by a voice in her head and the stirrings of long-dead emotions, can she regain her humanity and spread her wings?

Summary
All it takes is one choice.
A once-viridian butterfly flaps burned wings, and subsurface ripples intertwine, cascading into an exponential cacophony that threatens to drown not just Japan, but the very world. Whether to chaos, evolution, or control, Japan is sure to sink in the rising tide of villainy, as good intentions twisted by sinister minds pave the road to hellish destruction. Or, then again, perhaps not.
A choice made differently in the childhood years of Midoriya Izuku changes everything, and a more determined child now holds an iridescent strength of will, eclipsing even causality.
The nature of such obstacles is impermanence in the face of Determination, after all.

Summary
C4-621 Raven, a trans woman, has completed the events in game up to the Chapter 4 mission "Unknown Territory Survey", where our most major divergence point is situated. Instead of battling V.IV Rusty, a heartfelt confession wins over Rusty and Raven ends up joining the RLF early!
The early chapters will be focussing a lot on the RLF taking over Rubicon, and the actual erotic parts won't come until later. I assure you, the wholesome smut is the light at the end of the tunnel.
This is a retelling of AC6 to suit my desires, in particular certain aspects of some characters will have been changed. Accuracy to canon portrayals is not my primary concern, telling an entertaining story is. You've read the tags, you know why you're here.

Summary
The Augmented Human is perhaps the greatest development of the early 36th century. While earlier generations of C-Pulse were criticized for being barbaric and unethical, later generations were said to be inhuman, between a lack of emotional responses and the lack of memories to define the remaining personality.

Three weeks.
Three weeks it took to form a new government. Three weeks it took to contact the Interstellar Union and request reinstatement. Three weeks it took for her to get back in the cockpit.
And now that she was, Walter sighed to himself, she was on cleanup duty. At least the Institute had left records of their troubles.
At least, some of them. Rubicon had depths even he couldn’t fathom, and she seemed to stumble upon them all the time.

Summary
Walter had lost 617, 619 and 620 to the PCA. Now he had to grab the last of the batch, 621.
So, he goes and visits the same underground doctor to grab the dog. What he expected to get was a generation four augmented human.
Instead, a CEL-240 Unit from the IBIS Series, and a Generation 4.5 augmented human?
Why the hell did he decide not to grab the last of the batch earlier? And how the hell did the doctor not know that's an IBIS Unit?

Summary
It came without warning for most. The Fires of Ibis, a tide of flame that swept through the stars. At its center was the planet ISB2262, more commonly known as Rubicon-3, and the substance known as Coral. When the Coral was first discovered on the surface of Rubicon, it led to an industrial and scientific golden age for the planet, and Coral based technology and services became the planet’s number one export. Advancements in data analysis, energy generation, and extensive genetic augmentations were just a few of the wonders that were produced by studying the Coral.
And yet, as with all things, this golden age would not last forever. In the aftermath of tragedy, Rubicon has become a warzone filled with Corporation forces and Liberation fighters, both sides yearning to push the other off of Rubicon. In the midst of the conflict, a shadow from Rubicon's past will return to fly beyond its scorched skies... On the wings of a Raven.

Summary
Augmented human C4-621, callsign Raven triggers coral release for the 57th time.
Once again he is sent back to the beginning, but this time he keeps his memories and gear.

G5 Iguazu rembers everything too, the hundreds of defeats by 621 and the failures that lead to them.
What will he do differently this time.
Unfortunatly there are bigger forces at work, this time all the missions have changed for the worse, new enimies have arisen, and new faces appear from cracks in the timeline.
Can Raven escape the never ending cycle of torment, or will the cycles finally break him.
Follows multiple characters and POVs, plus we get daily life for the different factions.
Also Raven's a yandere and Allmind is here for some reason.

Summary
Alea Lacta Est. The die Is cast. Raven and Ayre cast the die for all of humanity. Hoping for that one chance, that one possibility, for symbiosis. For a golden future. Unfortunately, that die did not land on the result they wanted. Instead, Rubicon, and everyone on it at the conclusion of the Coral War, and even before, have been transported 38000 years into the future. Into the darkness of the 41st Millennium. Flung into the darkest reaches of space, barely at the fringes of several empires, They will have to adapt and come together as a single faction, so that they may survive or even better, thrive, in this new Galaxy. This would be no easy prospect, but once it is done, the Galaxy will come to know the name; The Liberators of Rubicon.
