Summary
He still couldn't believe it to be the case. He couldn't believe that Mari would still be standing in front of him, still smiling, still being happy, still loving him in spite of everything he put her through.
But Sunny knew the truth deep down, no matter how much he dreaded it and how much he wished for it not to be the case.
Mari is dead.
I killed her, and she ascended to heaven.
That thing possessing her corpse is not her.
TL;DR: “Mari survives the fall” meets “Mari becomes Something”. It only gets worse from here.

Summary
A long time ago... humans and monsters lived in harmony. Until war broke between the two races.
The humans were victorious and sealed monsterkind deep underground with a powerful spell, that could only be broken with the power of seven human souls.
This was the tale of Mt. Ebott, and the tale trascended into legend. Those who climbed the mountain, weren't seen again.
And so, begins the tale of the fifth human soul to fall into the land of legend, to fall... into the Underground.
This is the tale of the Purple Soul... Sunny Suzuki.

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
If you want to make some real money, call that number.
Mari stares at the string of numbers printed on the white card. Between her debt and her empty pockets, there's no guarantee that she'll be able to make it out of this pit she's been thrown in on her own.
If this offer is real, it could make all the difference. But if it's not...
There's only one way to find out.

Summary
"I want you to give Basil something. Could you bring a pen and two sheets of paper by tomorrow night? The sun is rising"
She didn't realise it was already morning. She didn't even realise she finally could see her brother's face now that she got used to the darkness.
He wore the same face as four years ago. It really was her little brother, but something seemed wrong. His eyes. His gaze. His hair. Everything about him seemed more empty. More dead.

Summary
Mari Suzuki is 17 when her mother divorced her father and took her brother. Suddenly having left a void in their family, Mari wonders where she and her father had gone wrong as they continue to live their lives in the small town called Faraway.
Sunny SZK is 18 when he'd been declared the Nation's sweetheart, or as they like to call him, sunshine, on live TV. He can see his mother behind the cameras and he flashes a smile, which gets thrown around social media for weeks. He's lived peacefully, but then an unusual message arrives in his inbox.
tl;dr I make Mrs. Suzuki divorce her husband and take Sunny with her, somehow, that changes a lot.

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.
--------------------------------------------------------------------------------------
Mari's history with self-harm, and multiple incidents in the year leading up to the recital.

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
(FORMERLY KNOWN AS “You’ll forget me”)
Two years. Two years since Mari left for college and never went back to Faraway town. Her college life is awesome, her friends are great and she can’t be happier with how things turned out. That is until she’s informed that her family will be moving away from her childhood town.
Dad is away with work and mom readies their new house, which leaves Sunny home alone and in need of a helping hand. At mom's plea, she drives back to visit Faraway Town one last time, despite not being so happy about it.
At least it was for three days only. Nothing bad should happen in such a short time.
___
An OMORI au focusing on the main cast dealing with Hero's death four years ago. Mostly Mari-centric.

With his sister still by his side and in his head to keep him safe, the boy goes to confront those he had left behind.

Summary
Mari finds a letter left behind by their mother.
(Takes place in the same universe as my fic "Sunny Suzuki's Harem of Childhood Friends." I highly recommend reading that one to avoid spoilers and confusion!)
(This is a prequel that deals with heavy topics such as toxic relationships. Please be aware that while I left it mostly vauge, the implications are not the nicest. You do not have to read this; this is for people who want more lore.)
