(Author's Note - Been listening to Quiet Water from Undertale along with some rain noises while writing for the past couple chapters. It makes me really sleepy. Don't know if the song's intuitive or counter-intuitive.)

Sora began to make his way down Waterfall. The area was both relaxing and intimidating, with the water pouring down wherever he went. The air was so dense and foggy that it became hard to breathe. He wasn't so burdened about Papyrus now that Sans had reassured him.

...

Somewhere inside Sora's heart someone was standing. Someone he recognized. He stood and watched as Sora walked.

"You must be so bored, with nothing to do in here."

The person in his heart turned around. Across from him was someone else.

"Surely you get lonely." The second said.

"Nah," Replied the first, "Sora's always making friends. I feel what he feels, when he feels it. I share his experiences."

"Really? That's what you think? That's just what he tells you so you'll stay put. This isn't a sanctuary, it's a prison. Don't you ever wanna stretch your legs?"

"...What do you mean?"

...

"Hey!" Sora heard a familiar voice "Wait up!" It was monster kid. They were holding an umbrella in their mouth.

"Here." Sora said, taking the umbrella from her.

"Thanks! We got kinda split up back there huh?"

"Yeah, I guess so. Sorry."

"Aww, it's no big deal! Hey, you're drenched!"

Sora hadn't noticed that it'd started to rain. He didn't feel cold.

"You alright?" Monster Kid asked.

"I'm fine."

"You're shaking! And you look kinda pale."

Sora hadn't noticed these things.

"... I guess so. Maybe I'm just sick. I'm sure It'll get better once I get outta this rain."

"Yeah, me too." The young monster replied.

...

"Sora's never going to let you go. He only tells you you can be your own person so that you won't try and escape. Even though he knows you wouldn't stand a chance."

"Get to the point."

"Join with me. I am made of pure darkness. You're only a husk alone."

The first eyed the second suspiciously.

"Together, two halves make a whole. A Heartless and a Nobody, who can weave together to create something stronger."

"... No. I know what you'll do with a full form. You'll create nothing but darkness."

"... No?"

At this moment, the second figure prepared a weapon.

"If you dare so defy me, you will pay the price, Roxas!"

"... What've I got to lose?" He summoned the Oblivion. "A heart? A body?" He summoned the Oathkeeper. "Axel? Xion?" He put on his cloak. "It's just like you said." He pulled up his hood. "I'm just a husk."

"Well then..." The second figure smiled, pouring with red darkness. "Time for plan B."

...

Sora was quiet. He didn't know why but he was hurting inside. He and Monster Kid had been walking silently for a while, and the rain had stopped. He looked down in the water. It was him still. But he felt disappointed. Like he'd expected to see somebody else in the rain.

"You sure you're ok Sora?"

He smiled at monster kid. "I'm fine. Why don't you go on ahead? I need to take a break."

"Ok!" She agreed. "See you later!"

Sora stood in place, even when she was out of sight. Looked at the water puddle on the ground. Despite the fact that it had stopped raining, the sky was still dark. Sora looked up and saw the hole in the roof of the cave.

"It must be night out there."

...

"If you will not ally with the darkness," Said the second figure, "then it will destroy you!"

Roxas charged at the figure with the Oathkeeper and sent several attacks with both weapons. They were all blocked by the dark figures blade. They both went into a deadlock with their weapons, constantly pushing against one an others power.

"Some things are better off destroyed..." Roxas answered.

"Like Xion?" The figure asked, its eyes shining brightly. Roxas' did the same in disgust. He jumped into the air and smashed down on the figure with the oblivion, this time hitting.

The figure backed away. "So you fight for the light now? Some hero you are, killing your friends."

Roxas flared to life. "Shut... up!" As he said this he dashed at them putting all of his strength into a charging sweep.

"Sora's a hero of the light, Roxas. He protects his friends. He cares about more than ice cream."

Tears began to flow down Roxas' face "I told you to shut up!" He leaped into the sky. The sky became something. Twilight. Beneath the two shadows of nothing, Sora's dive to the heart was created.

Beams of light began to shoot down. The shadowy figure dodged every one of them. "A shadow like you only fades when they reach the light!"

The figure jumped into the air, slashing at Roxas. They knocked the Oathkeeper out of his hand and into the abyss below Sora's heart. Roxas began to fly across the stage. And he began to fall of. Just before he would've fallen into the darkness, he jerked the Oblivion into the ground.

"Who... Are you?" He asked.

The figure in the dark put their foot on the keyblade supporting Roxas.

"Me?" It asked, "I am just like you. I was weak. Stuck in the shadow of others. I had no real friends until I met my 'brother.' I'm just like you. Darkness, clashing with the light. You want to know who I am?" The Oblivion was growing weaker and weaker every moment. "You should know already, Roxas. Just like you," it smiled, "I'm someone from the dark."

The Oblivion shattered in two and Roxas fell into the Oblivion below him. "No!"

'Axel... Xoin... Sora...' he thought as he sunk. 'I'm sorry.'

"Don't worry Sora..." The dark figure said, "I'll step in to take that Nobody's place of control in your heart."

...

Sora watched his reflection. Right now, all he could feel was pain. He didn't know why. Sora fell to his knees and began to cry. As he cried he watched the water. His reflection could be seen... But it was different. It now looked more like someone else, now that his tears had rippled in the water. It looked like Roxas. But his eyes... were shut.

Sora continued to cry... He didn't know why, but somewhere inside... He felt like laughing.

...

"Hahahaha! How pathetic to cry at the loss of a puppet..."

...

(Authors note - I got to do a lot of things I was looking forward to this chapter. the first was introduce Roxas. The second was to kill off a character. The third was introducing 👌 👎✡👍✌💣 .)
