A/N: This is my first full-length Undertale story, and only my second one I've written for Undertale, so don't be too critical.
With that in mind, let's go forward.
They had been fighting so long, longer for her than her opponent. He had killed her many times, and even seemed aware of it.
Now, though...
Now.
Now he was going to die at last.
The blade sliced forward, and the skeleton leaped to the side. "heh, didja really think you would be able-"
999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999
A fierce grin cut across her face as she studied his fallen form. Blood oozed from the gash across his chest and from his mouth.
"well... guess that's it, then. just... don't say I didn't warn you."
Savage happiness sliced through her... and then, something fractured.
What have I done?
"No!" she shrieked. "Sans, I'm sorry!"
"too... late for that," gasped the skeleton. "there's... only one way..."
"I know." Tears trickled down her cheeks. "I shouldn't have even started this!" she moaned.
The faces of the dead loomed in her skull. "Frisk..." they moaned.
And then a tear trickled across a mouth that was now split in a fierce grin.
"But there's no reason I shouldn't have an advantage when I reset."
She reached out towards Sans. "what..." he moaned, and then suddenly realized what she was going to do. "you can't. i won't let you." he gasped.
Frisk lifted an eyebrow. "How are you going to stop me?"
Sans's soul was beginning to shiver and fracture. "No, you don't." growled Frisk, and rammed it into her own chest.
There was blinding light, and she felt herself being lifted off the ground-
RESET
The same darkness, and the patch of flowers beneath her.
"Just as before."
"what happened? i really hope that this is a dream... wouldn't be the strangest..."
She did not pick at his memories, instead walking forward towards the entrance to the ruins. I will not abuse my powers.
"powers? oh... damn."
Ignoring the skeleton once more, she headed into the next chamber.
There he was. The little yellow flower. Innocent-seeming, but really a deadly foe.
I should know.
"Don't you have anything better to do?" the flower asked.
"Howdy, Asriel." Frisk replied, allowing herself a momentary grin.
"Well, then..." Flowey sighed. "Let's just get this over with."
"You idiot!" Frisk rasped, causing the flower to flinch away. "You should realize the true power I have within me! It is a power, after all, you have known yourself." she added.
"You... You..." Flowey stuttered. "You merged with a monster's soul?"
"Right before I reset." Frisk nodded. "I need an edge. After all, in this world it's kill or be killed, isn't it, Asriel?"
"Stop calling me that!"
"I know everything, now. I will use my powers to shape the world as I see fit, Asriel. Now, scram!"
With a frightened glance at Frisk's eyes, the yellow flower vanished into the ground.
"That's better." Frisk allowed a chuckle, then strode forward. There was still the business of getting through the ruins to get through.
A/N: A little short, but I still hope everyone will review and come back for the next chapter.
