Summary
Mari died. And became a ghost. Would be cool, if she didn't accidentally step into a whole new world made out of creatures and inexplicable occurrences.
However, when presented with the possibility of a second chance at life, she is eager to take it.
After all, she is a bored ghost ! And a bored ghost is meant to strive for entertainment.

Summary
A pristine white gown covers them from head to toe, smooth and unblemished. Their perfectly groomed, straight black hair ends just past their shoulders, symmetrical on both sides, as her bangs part in the middle of her forehead just above her mask.
The rounded theater mask matches the white of their dress, the curved edges of the mask melding into their pale skin as if it were part of their very being. The caricature of a happy smile is carved into the mask, but there’s no sign of anything beyond the veil of the mask's sockets. Mari... she… she recognizes them now.
“Good, you’re paying attention.” They… Kanpeki, hums. The other woman clicks the pen in hand as she jots something down on the paper next to her. “We can begin then, and I think a good starting point as any is why you’re here.”
Kanpeki 完璧 (noun): perfect; complete, flawless. Or in other words... another Omari AU, but things are a little different.
Because naturally, Mari's a little different than Sunny.

Summary
After many births and deaths of the universe, all of which were under the same principles of magic and energy, a being beyond time itself, a god some people would call it, decided to try something new.
A human family. She just uh... has to figure out why this world is lacking everything she's normally used to, how to fit in... and uh...
Why the hell is magic being used so weirdly.
What the fuck is an engine!?!?I took Mari, made her into a god beyond all time and space, threw together a (probably) unique magic system, and created this. While some major plot points in the Omori story may still come to fruition, this won't be too directly tied to it.
First chapter is to explain my take on a magic system.This is absolutely a first time fic, so don't expect much.

Summary
"So make the friendship bracelets, take the moment and taste it, you've got no reason to be afraid."
Mari was alone. Really alone. Her parents never really seemed to care above the surface level, her friends and brother relied on her. But when would she be able to rely on anyone?
Prequel to my last Marigold AU fic "It's not your fault (I'm sorry)"

Summary
While practicing for the recital, Mari happens to notice something that - in another world, where she saw things a little differently and had slightly different priorities - she might not have. Though nobody realizes it, this prevents a certain argument and everything that could have followed it. Now she just has to make sure Sunny's okay, and that the recital goes perfectly. But being a big sibling can be hard, especially for someone like her.
(Or, the one where Mari is autistic. This changes less than you'd think, yet changes everything.)

Summary
The grand window above the crib had been opened to let light in, crimson curtains waltzing lazily with the summer breeze. Outside, Mari could hear the trees whispering softly, gossiping with curious leaves as rays of sunlight capered about the floor. Before she'd even seen his face, it felt like the universe was telling her.
Don't worry, he'll be perfect.

Summary
Mari has the perfect life. She goes to college, has partners, smiles with her family.
But it’s only a mask.
How do you keep living when you’re empty? When the most precious person to you is taken away. Not by accident, but by someone’s hands?
She swore she would protect and love her brother with her own life, but she did the opposite.
Now she must face a truth she cannot escape: Sunny is gone, and she is still here.
This is the story of her life without him… and the shadow he left behind.

Summary
Mari was dying, she was sure of it.
People say that theres some time before your thoughts are gone, too, or at least that's what Mari remembers hearing. Perhaps that was what she was experiencing now.
So in her last moments, she's sure to think...really think about her life.

Summary
What if things went differently on the day of the recital? What if Mari had lived... But Sunny did not?
This is the guide for role swaps-
Mari ⇄ Sunny
Hero ⇄ Basil
Aubrey ⇄ KelHi! This is my take on the Omari au- I love Mari, so I wanted to take her character and throw it into a situation :)
Update! On a hiatus, I guess, writers block is a bitch
Another update- this is being orphaned, I have better ideas to tell the story

Summary
If you want to make some real money, call that number.

Summary
Sunny has always been a silent boy. His family learned that quickly, none more-so than his doting older sister. She learned all of his little tells. Those minuscule changes in his facial features that show those adorable, oh so rare emotions.
But lately it feels like his expression hasn’t been changing much from his usual stone faced demeanor. If anything he has been displaying less happy emotions and more sad ones. What could be bothering her sweet little brother!? She will find out or her name isn’t Mari Suzuki, best big sister in the world!
Or
Sunny is being even less expressive than normal and is displaying more negative emotions. Mari is intent on finding out why and remedying this.

Summary
From a very young age, Mari had always been a perfectionist.
When she was very young, she would have mental breakdowns about her hand-writing not being perfect. She would scream and cry and hit herself over and over again. People would have to calm her down and reassure her that whatever she was throwing a fit over was good enough.
They didn't understand.
How could they not see it?
How could they not see how wrong it was? Were they just being nice? Or did she just see things that they didn't?
She was eventually able to grow out of that by age 8 or 9, but the instinct never fully went away.

Summary
“But don’t you five despair!! I still greatly value our friendship, and your individual talents,” Mari began, adjusting her suit. She had, admittedly, never worn one, and while she liked how it looked and felt, she was still getting used to it. “I can offer you full time contracts here at the casino! Of course, there’ll be no pay or vacation days, but... I’m sure this will teach you all invaluable lessons regarding efficiency and hard work!!!”
“What the- no way!! That’s awful!!” Aubrey exclaimed in response. “Qu-quick, Omori...!!! We have to do something!!!!”
----------------------------------------------------------------------------------------------
Nothing's been pressing lately, so things have felt pretty calm in Headspace for Mari in recent times. Maybe a little too calm... but perhaps inheriting 51% of the Deep Well and an unhinged lust for power will spice things up for her a bit!
(Or- AU where Mari accidentally becomes the boss of the Last Resort instead of Hero, chaos ensues.)
