Chapter Text

Mari couldn’t stand this anymore. Waiting in heaven, watching Sunny decay and hide within himself. Four years of this was enough! She wouldn’t stand idly by anymore, she had to do something to help her dear brother! Mari floated off of her personal cloud, and made her way to one of heaven’s help desks. The angel in front of her smiled warmly, and said “Hello, my name is Catrina, how may I serve you today?” In a gentle, polite tone. Mari said

“Hello, yes, I would like to know if there was any way I could help my little brother.”
“Alright, I’ll pull up you and your brother's files, just a moment please!”

She disappeared in a puff of clouds, before reappearing a few seconds later. She had a face full of regret, and said “I’m sorry, but there isn’t any way you can help him.” Mari was filled with sadness. But she wouldn’t give up yet. “Please, I will do anything! I just want to help my poor baby brother!” With passion mixed with fear.

Catrina sighed, and said “please give me a moment miss.” She disappeared before Mari could inquire anymore. A few minutes passed before she returned. Mari jumped up from her white fluffy waiting seat, and said “So, can I help Sunny?” Hoping and praying with all her being that the answer was yes.

Catrina sighed, and put her glasses down. “Yes… but you might not like it.” Mari replied without hesitation “Please! How can I help him?” Catrina looked at Mari with what looked to be pity and sorrow. “Ok… if you really want to help your little brother… ok.”

She put her hands in a praying gesture, and Mari immediately felt pain. Everything hurt. Her body was contracted, melted, blackened. Her mind felt like an inky dark was flooding her mind. But for Sunny, she would endure. It almost felt like she was falling as her transformation continued. Before long, her mind was almost completely changed, and her body was nothing but a black blob.

——————-

Something materialized from the air, before falling to the floor with a heavy splat sound. It opened its eye. It was in a blank, barren room. It needed to find a host. It’s eye swept the room, before it landed on a bed. It had a small, sleeping boy within its white blankets. It felt drawn to it, and made its way to the black haired boy.

It turned the boy so his back was facing up, and it latched onto the boy’s back. It could feel itself melding into the boys flesh. Good, now it had found a host. It sent out four black tendrils, and integrated them into the child’s limbs. Lastly, it sent a small fragment of itself into the frail one’s ear, being careful as to not damage anything as it made its way to the cerebral cortex. It hesitated though, and instead of taking control of the boy’s body, it decided to go to the bloated Hippocampus of the boy, and latched onto it. It felt like it had to do something.

Omori finally made his way to the end of the Hidden Forest with the rest of his friends. There, Daddy Longlegs awaited them. “Ahh. So you made it to the end of this hidden forest. Congratulations. Now, I will tell you a sto-“ Suddenly, the dream realm shook to its very core. Parts of the colorful world began to grey and blacken.

What was happening? Daddy Longlegs spoke once more, saying “Strange. This world is breaking. Yet, not at the right place, or the right time, or by the right person. This is very mysterious. It is unfortunate that I will not be able to find out what, or more accurately, why this is happening. Good luck boy.” That last sentence almost sounded like it had a hint of pity. With that, the Dream World crumbled, leaving only Omori, and Something.

Although, it felt different from the ever staring eye of guilt. It felt almost… real. A sickly smooth, yet sinister voice echoed through the black abyss. “I think it’s about time we got rid of those delusions, don’t you boy? Let’s get rid of that fake skin as well.” A black tendril shot out of the figure, straight through Omori’s chest. The monochrome boy gasped and clutched the tendril, before life left him, and he crumbled to dust. Good. No more hiding in his dreams for him.

Sunny woke up with a gasp, and in a cold sweat. What a strange dream. Even stranger than his usual, which was quite a feat of its own. He brought his hand up to his face, and rubbed the sleep out of his eyes. When he brought his hand away, he was startled to find a small, thin black line going down his entire arm, getting thicker as it went up the arm higher. Maybe it was the cold embrace of death slowly taking hold of him.

Sunny felt like there was a small weight on all of his limbs and back. Sunny made his way to the bathroom. He was thirsty, and luckily he had brought a clean glass up a few months ago. He walked into the dark room, and flipped the switch. Nothing happened. Hmm, maybe he should start answering mom's calls more often. Probably just the electricity going out. Ohh well.

He was about to fill his water cup and take a drink, until a familiar, sickly sweet voice rang out through his head. “That’s not healthy, little boy.” Sunny froze in fear. That was probably just his mind messing with him. Just drink the water. Drink the water and go back to sleep. Sunny brought the glass up, but felt a sudden pain flare up in the back of his head, and he couldn’t move a muscle. A black thing that almost looked like a head moved out from behind Sunny’s back ,an eye very similar to Sunny’s hallucinations in the middle of the head. He heard the voice again. “What did I say? That’s unhealthy, and I’m certainly not letting my host get hurt or die.” Sunny became AFRAID.
