Hi guys! Right now, I'm currently writing ExperimentTale, but I also wanted to try making an Undertale x Kingdom Hearts crossover AU. In it, the Underground is part of an alternate version of Destiny Islands. This chapter picks up right before the Heartless attack Sora's island in Kingdom Hearts. If you guys like this FanFic, leave a like/follow and a review on your thoughts on this chapter! Enjoy.
Also, the title of this chapter is named after Kingdom Hearts's theme song! Every chapter will get named after either an Undertale or a Kingdom Hearts OST.
When you walk away
You don't hear me say
Please, oh baby don't go
Simple and clean is the way that you're making me feel tonight
It's hard to let it go
You're giving me
Too many things, lately
You're all I need
You smiled at me, and said
Don't get me wrong I love you
But does that mean I have to meet your father?
When we are older you'll understand what I meant when I said no
I don't think life is quite that simple
When you walk away
You don't hear me say
Please, oh baby don't go
Simple and clean is the way that you're making me feel tonight
It's hard to let it go
The daily things (like this and that and what is what)
That keep us all busy
Are confusing me
That's when you came to me and said
Wish I could prove I love you
But does that mean I have to walk on water?
When we are older you'll understand it's enough when I say so,
And maybe some things are that simple
When you walk away
You don't hear me say
Please, oh baby don't go
Simple and clean is the way that you're making me feel tonight
It's hard to let it go
Hold me, whatever lies beyond this morning
Is a little later on
Regardless of warnings
The future doesn't scare me at all
Nothing's like before...

Chapter One: Simple and Clean
During the Keyblade War, two races fought each other: humans and monsters. When the war ended, the humans emerged victorious. It was decided that the monsters would be sealed in a realm that existed under the Destiny Islands, an archipelago where a rare commodity know as the Paopu Fruit grew. Legend has it that it will take seven special, human children to free the monsters from their prison. Eventually, centuries passed, and almost everyone forgot about the monsters. It seemed like it was an urban legend, an old wives' tale.
A population of ten thousand people lived on the Destiny Islands, living relaxing, rural lives in the seaside town of Ebott. However, reports recently came in, saying that six children have gone missing. One island was home to a mysterious cave with a clandestine door, said island of which was where all six children were seen before going missing. And while no one seemed sure of how or by what means the children went missing, people stayed away from the cave...
Well, except for four teenagers...
Sora...
Riku...
Kairi...
and Frisk.

Sora was a fourteen year old boy who lived on Hikari Island with his six friends. He was an orphan with brown, spiky hair, a mostly red attire, and baby blue eyes. The boy sat on his bed inside his ship house, thinking about the great adventure he and his two best friends, Kairi and Riku, would have once they sailed away to another world. The three of them were the closest friends on their world, nearly inseparable when together.
Sora got up from his bed and took out a backpack from under his bed. He began to stuff it with items he wanted to take with him once he and his friends began to leave. He packed some of his favorite snacks, extra pairs of clothing, and even stashed his Gameboy Advance in there. He was ready.
This trip is going to be awesome!
The boy left his room to go and put his backpack in the storage area of his raft. But once he left his room, he noticed a figure climbing the ladder that lead to the rest of the island.
"Huh?"
Sora equipped his backpack and climbed the ladder after the mysterious figure. As soon as he climbed up and out of the ship, he took a clear look at who was fleeing from him. It was none other than his fifteen year old friend with white hair and aquamarine eyes.
"Riku?" Sora asked, puzzled. "What are you doing out here?"
"Sorry, Sora." Riku apologized. "I didn't mean to wake you."
"Nah, don't worry about it. I was already awake, and was about to add my backpack to our supplies."
"Uh, okay. Anyways Sora, neither Kairi nor Frisk were in their rooms."
"What!?"
"Its true. Both their doors hung open, so I was going to search for them."
"This isn't good." Sora stated. "They could get lost and hurt out here. We've got to find them."
"I agree. Let's go.
Kairi was very important to Sora and Riku. One day, nearly a decade ago, the two boys found her on their island. Ever since that day, those three were great together. Kairi even hit it off with the four other kids who lived on the island: Selphie, Tidus, Wakka, and Frisk. Speaking of Frisk, she was an introverted, yet nice twelve year old girl with brown hair. She spent most of her time hanging out with Selphie, a thirteen-year old girl who admired the sea and obsessed over the legend of the paopu fruit (a story for another day).
Sora and Riku scoured the beach, searching for their friends, but to no avail. It was a dark night, which made it extremely hard to see anything other than the beach.
"Sora, let's search the cave." Riku called to Sora.
"Alright!" Sora replied.
They rendezvoused at a small opening covered by harmless ivy. Riku crawled in first, with Sora following closely behind him. This cave brought back precious memories...
Sora sat on his knees, drawing himself and Kairi on the cave wall. Kairi kneeled next to him, drawing herself and Sora each eating half of the same paopu fruit.
Selphie's words from earlier today rang out to Sora.
"Hey Sora, have you heard about the legendary power of the paopu fruit? Legends say that if you share it with someone you really care for, it binds you together forever and ever through eternity. Its so romantic..."
Once the two boys made it to the cave's only room, something they never thought would occur happened right in front of their eyes. The clandestine door was open... A beautiful light was shining... And standing in the opening was Kairi, who was laying on the ground, barely holding on to Frisk's hand. Beyond the door... was a hole.
"Kairi!" Sora shouted, rushing over to help her life Frisk up.
"Help me, please!" Frisk pleaded to Kairi, who was trying very hard to hold onto her. But then suddenly, the light grew brighter, and an ominous wind blew both the girls into the hole!
"KAIRI! FRISK!" The boys shouted in fear as they too got blown through the door, and down into the hole. And with that, the door swung closed.

Day One
It started as a peaceful day in Snowdin Forest. Sans the Skeleton snoozed at his sentry post without a care in the world. Usually the laziest monster who lived in the Underground, Sans was twenty-four years old, and his job as a sentry was to watch for humans who fell into the Underground and capture them. The only two reasons he got this job were to sleep and have a means of getting paid. Nothing more.
His brother Papyrus though, while he was friendly and trustworthy, was a human-hunting fanatic. He wouldn't really hurt a fly unless they attacked him relentlessly, but true to his job, he set up many puzzles to slow humans' progress through the forest. Sans cared about his brother a lot, and would protect him without question.
As the skeleton slept though, a dark wormhole began to form on the ground deep in the forest. Papyrus, observant as he is kind, couldn't help but notice a pitch-black, tiny creature crawl out of it.
"EH? WHY HELLO THERE!" Papyrus greeted what he thought was a migrating monster. "I'M THE GREAT PAPYRUS. MAY I ASK WHAT YOUR NAME IS?"
The Shadow however, was not here to chat. He leaped at Papyrus, trying to jump kick him. Papyrus easily dodged the attack, thinking he may have offended the Heartless.
"OH NO. DID I DO SOMETHING WRONG?"
But at that point, he realized he and the lone heartless were not alone...
"SANS! I THINK I NEED YOUR ASSISTANCE!"
Sans woke abruptly and, using his blue magic, teleported to Papyrus' side.
"whats up, bro-"
But Sans was cut off by the sound of clinking metal. A few Soldier heartless lunged at the skelebros from the dark wormhole that encompassed the ground. They both dodged that attack, and Sans tried to counter them with magical bones from the ground. But the bones merely bounced off them.
"huh?"
He summoned a Gaster Blaster, a magical machine which was able to take the heartless out. Then out from the shadows came a giant heartless, which resembled a buff hobo with long hair. They called it Darkside.
"what the hell!?" Sans reacted, summoning a few more blasters to attack it. They did minor damage to that hulk. Papyrus had finished wiping the floor with the other heartless when he noticed Darkside.
"SANS... WHAT IS THAT THING!?"
"i dunno, Paps. but the best thing you can do is go and warn everyone."
"ME? BUT WHAT ABOUT YOU?"
Darkside punched the ground, creating another wormholes that spawned Shadow heartless.
"just get outta here! I'll be fine."
Papyrus nodded and fled the scene, leaving Sans to deal with the heartless.
"take this!"
The short skeleton called forth a dozen more blaster to take out the shadows. However, Darkside was barely even hurt at all. Darkside began to shoot spheres of darkness from an opening in its chest, which was shaped like a heart. Sans used his blasters to protect himself, but upon contact, that blasters broke.
"how is this possible?"
Darkside punched another wormhole into the ground, spawning an Invisible, a winged heartless with a sword in hand. Sans teleported out of its way, but quickly realized that it was much faster than it looked. He kept teleporting out the way of its attacks, but the heartless kept getting faster, and Sans was growing ever so tired. He summoned bone attacks, but to no avail. They shattered upon hitting the heartless.
"damn it." He mumbled, kneeling, out of breath.
He felt a sudden pain in his stomach! The Invisible had impaled him...
"so... that's it, huh?"
His saw his 'heart' floating out of his body, and into the wormhole of darkness. As the Invisible pulled his weapon out of Sans' body, he shed a tear, knowing that Papyrus was okay... before turning to dust...
"i'm sorry... Papy..."

The monster was falling...
Falling...
Falling into darkness...
No light...
No escape...
No hope...
