Summary
A single mistake can have devastating consequences. But every action has an equal and opposite reaction...
Three days before Sunny is due to leave Faraway, Aubrey wakes up in a world where she has everything she’s ever wanted: Mari's alive, her former friend group is intact—hell! She's even dating her old crush!
By all accounts it should be a dream come true... but it feels like a nightmare.
Can Aubrey accept this new reality? Will this world even accept her? And what happened to the girl whose life she just hijacked?
TLDR: Aubrey gets isekai’d into an everyone-lives AU, swapping places with her counterpart. Angst and fluff ensues (with just a little bit of crack, as a treat).
ACT 1- Rude Awakenings: 1 - 12.
ACT 2- Oh, Mari: 13 - ?

Summary
“M’scared of Something behind the door.” Sunny mumbled into his shoulder.
“What exactly is behind the door?”
“…”
“M-Maybe if we see what’s behind it, It’ll stop being so scary.” Basil suggested. Sunny nodded.
Together, they walked up to the small door. Basil took a knee down to it as Sunny stood to the side.
With another nod from Sunny, Basil grabbed onto the edge of the door and pulled—
***
Something happened to Mari almost three years ago. It’s up to Sunny and Basil to find out what happened with help from Kel, Hero, Aubrey, and other residents of Faraway.
All they know is that Something behind the small door had a part to play in all of this.

Summary
There are many things that can be forgotten, both big and small. Omori helps Sunny remember.
Sunny opens his eyes. Above him looms a familiar paper white face framed with dark graphite hair. Omori is crouching over him, their arms wrapped around their knees. They’re staring down at him.
The thin rug Sunny lays on is soft. He might have enjoyed it if Omori’s socks were not poking the top of his head. Or if he did not know what it meant to be in WHITE SPACE.
“Why am I here?”
“You forgot something.”

Summary
Whatever the reason, it didn’t matter much now; Omori was here, which meant the boy he had replaced was now off in the Land of Faerie. Nothing he could really do about that, he thought, trying to ignore the bitter feeling growing within him.
What mattered now was that he was a human, and was now going to have to live like one. He was now…”Sunny.”

Summary
Mari has lived as a ghost within the walls of her house for seven years now. Seven years since the day she was pushed down the stairs...
More than anything, she just wants her little brother Sunny to forgive himself. But she's watched horrible things happen these last few years. Sunny locking himself in his room. Dear, sweet little Basil taking his own life. Aubrey and Kel drifting farther and farther apart. And Sunny leaving, never to return...
Until today.
It's been three years since the day Sunny moved away and never looked back. A family has moved into the house---a family Mari would do anything to protect. But there's something about Sunny that isn't right. He's not the boy who left all those years ago...in fact, he seems to be a different person entirely...
Turns out the fallout of Mari's death isn't over quite yet.

Summary
Sunny's eye shot back open at the sensation of something pressing down on his stomach. An arm. As pale as a sheet of paper, cut off at the shoulder as it seemed to project out from Sunny's black shirt, the arm was in stark contrast to the dark fabric. Bent at the elbow, it tensed before pushing and pressing its palm more forcefully against Sunny's stomach. Nausea spiking for a moment, Sunny swallowed a pained gasp before shakily pressing himself further into the wall in a futile attempt to escape the situation. The hand froze and immediately paused its movements. A metallic clang sounded in Sunny's ears, and his breath hitched as the glint of a blade entered his vision.
After Sunny tells his friends the truth, he can't bear their reactions. Consumed by guilt and self-hate, he very nearly succeeds in throwing himself from the hospital balcony. After moving to his new home without another word to any of them, Sunny's mental state is only deteriorating further. His hallucinations may have been getting worse, but this one of Omori seems a bit too real...
As his friends struggle to reconcile with what Sunny told them and what he'd nearly done, Kel is, once again, the first to reach out.

Summary
This is getting stupid.
Overwhelmingly, obviously, stupid. How long can you pretend something as shallow as a few hours of consciousness makes you a person? Everyone's patience is running thin, He's sure of that. No matter how much everyone wants to pretend they want him around, this has to end soon.
"You still brooding over here?"

Summary

How will Sunny cope with this twelve year old little shit reappearing while visiting Faraway? And how will he heal through all his trauma? Read now to find out!! (This will probably suck don’t sue me)
Or:
I had an idea for a one shot but I decided, ‘hey, why not try to make this a full blown series?’ So yah, here we are. Enjoy!! Hopefully I can at least do 3k words per chapter, more if I can but I'm just a poor boy who sucks at writing. (also lets see how long it takes for the AO3 author curse to get me)
Try not to expect updates fast because I’m very slow and my attention span is that of a toddler
Also u should totally check my tiktok where i post very sane things and art sometimes, the tag is chasinqlilypart2

Summary
Sunny did it. He confessed the truth to his friends after defeating Omori. I guess Sunny had no use for him anymore. He was created to protect Sunny from the truth and everything else. But now that Sunny didn't need him anymore, I guess he would just disappear.. or not?
Post-Good Ending Omori arises in the OMARI AU.

Summary
Omori is out adventuring in Headspace again and Sunny is bored in White space. It isn't a bad place to stay in but also not very fun. Suddenly, Sunny gets an interesting idea.
What if he tries to go to Headspace without Omori taking over him? Omori never said anything about not going there alone. What is the worst that can happen?
... Ok maybe a lot of bad things, but it wouldn't hurt that much to find out. Probably.
