Undertale - Aftermath

Chapter 1: SOUL

DISCLAIMER: Undertale belongs to Toby Fox.

"Well..." Asriel looks through the hole of the cave, "I destroyed the barrier, everyone will be free at last." then turns to the fallen child, "You should go, too. You have a home to come back to, right?"

The child nods.

"I think this is goodbye." Asriel wipes off a tear in his eye, "It's best if you go now."

But the child shook its head.

"Why? Is there something you need to do first?"

The child just smiles at Asriel.

"Uh..." Asriel scratches his head, "I don't get you sometimes, Frisk"

Frisk steps closer, their cheeks are blushing red.

"F-Frisk?"

With a small hop, Frisk jumps to hug Asriel.

Asriel is left speechless, his cheeks grows red as Frisk hugs him tighter.

"Ha ha..." Asriel hugs Frisk back, "Wow... I don't want to let go..."

Frisk steps backward as they breaks their hold.

"Thanks." Asriel gave a sincere smile, "I feel much better now."

Frisk grabs Asriel' right hand, "Come with me."

"Oh!" Asriel looks stunned, "You actually spoke." he then shook his head, "No, I can't come with you. Without a SOUL, I'll turn into a flower again."

Frisk hold their chest, then pulled out a red, heart-shaped SOUL.

"Your SOUL? What are you going to do with it?"

"Share." Frisk holds out the SOUL to Asriel.

"Share? You mean share your SOUL with me? Is that even possible?"

"You can come with me." Frisk maintain their smile.

"But, if absorb even a piece of your SOUL, won't you be hurt? Or worse?"

"It will work."

"How do you know for sure?"

"I like you..." Frisk' cheeks turns red.

Asriel' cheeks grows pink, "W-Well, if you insist..." Asriel hesitantly holds Frisk' SOUL, "Are you sure about this?"

"Hmhm." Frisk nods.

"I'll try ro absorb half of your SOUL, and this might hurt..." Asriel stands there, sweat running down his forehead, "Golly, is it hot in here?"

"Do it, Asriel."

"Alright, here goes!"

As Asriel channels magic through Frisk' SOUL, it began to glow red, multicolored energy sparks through it, transferring Frisk' life force to Asriel.

"I-I can feel it! I think it's working!" Asriel grunts as he concentrate on balancing the life force so it does not kill Frisk, while Frisk seems to be holding pain as well, they doesn't make much noise.

After a while, Asriel stopped channeling his magic, he then puts Frisk' SOUL back to where it belong, "Whew, that was intense." he wipes off the sweat on his forehead, "Are you okay, Frisk?"

Asriel can't tell if Frisk is still there or not, "Frisk?" Frisk can barely stand, but then they slumps to the ground.

"Frisk!" Asriel tries to grab Frisk before they fall, "Oh, I should've known!" Asriel hurriedly carry Frisk away.

* Hours later...

When Frisk finally managed to open their eyes, they can barely hear noises from the distance, "So you TRIED to absorb half of Frisk' SOUL?"

"It was his- Uh, her- Ah, it was Frisk' suggestion!"

"Are you sure you only absorbed half of Frisk' SOUL?"

"W-Well, I'm pretty sure there's still life force on it."

"I'll do a checkup just to be sure."

"O-Ok."

"It's best if you go back to your parents, Asriel."

Frisk tries to get up, but there's a sharp burn on their chest stopping them to even move an inch from the cold... operating bed?

Frisk looks around, the area seems familiar, but they doesn't recognize this particular room they was in. Before they know it, the door swung open, revealing a yellow monster wearing a lab coat.

"Oh, Frisk! You're awake!" the monster moves in closer, "I guess Asriel really did it after all." the monster sighed in relief.

"Sharing a SOUL with another... I never thought it would be possible!" it then thinks to itself, "Maybe human SOULs are stronger than we know. How much determination do you have?"

Frisk holds their chest, as the burning pain still exist.

"Your chest is hurt? It must be a side effect from sharing a SOUL." the monster grabs a book from a nearby bookshelf and opened it, "Hmm..." it flips page over page before exclaiming, "Ah, I think know how to heal your pain!" then closes the book and put it back in the shelf.

"As your SOUL and Asriel are now shared, you only have half of the power of a SOUL. But with the amount of determination you have, your SOUL might recover by itself..." the monster pauses for a while, "W-With Asriel' help, to be exact."

Frisk tilts their head in confusion.

"W-Well, it's kinda hard to explain..." the monster began to sweat, "Um, w-why don't you rest here for now? I'm sure you're fatigued after whatever you did for sharing your SOUL." the monster pulls out a blanket at covered Frisk with it, "I know, the bed is cold."

The monster turns away and leave the room while closing the door.

Frisk tries to stay awake, thinking about Asriel even if there's a merciless burn on their chest, they really wants to spend time with Asriel now that he's alive again. But each minute it became harder to stay awake, and they finally slips unconscious.
