(Y/N)'s P.O.V.

You've had enough. If Sans was going to hurt Frisk like that over a stupid mess, then you didn't want to stay there. Not with his temper.

"Thank you for letting us stay here, Sans", was all you said before walking through the front door.

You trudged through the thick layer of snow, but kept walking. Entered what looked like the place Sans showed you, and you felt a tinge of guilt.

He had almost killed your little sibling, yet you were the one who was left feeling guilty. Something deep in your soul told you to go back.

But you ignored it, forgetting about the feeling entirely. Why would I want to go back if- Your thoughts were cut off by a familiar gruff voice.

"I'm not scared of you or Sans anymore," You heard Undyne say, before you felt an agonizing pain in your back and stomach. You drop Frisk and look down at your injury.

A spear. A familiar cyan spear had impaled you, and blood spilled from your devestating wound.

You staggered and tried to stay up, but you fell. While slowly bleeding out, you grew tired. Your vision turned blurry from blood loss.

All you saw before you finally closed your eyes, was a chaotic tornado of blue and white flying around you.

You weren't going to make it.

Sans' P.O.V.

no. No. NO!

Sadness, guilt, and mostly anger filled my soul as I watched (Y/N) fall limp, exactly what I wanted to prevent.

Undyne just stood there, waiting. Waiting for her to finally die.

And there it was. A violet soul had appeared above (Y/N)'s dead body. When I saw it, I just snapped.

I sent a barrage of attacks in Undyne's direction, and the majority of them hit her. Blue attacks, normal attacks, even my Gaster-Blasters were used.

But she was still standing. Well- kneeling, I suppose. Her health was drastically low, and she looked at me with determination, while I stared her down with hatred.

"Hmph. I knew you were low, but to betray the entire kingdom is a whole new level of pathetic," Undyne said, standing up.

I threw more attacks at her, tears starting to form in my eye-sockets.

24 hp.

"I didn't care how you felt, I cared about the underground." She took a step. A bone flew at her, going clean through her armored shoulder.

18 hp, and she continued to walk.

"I didn't care if she was innocent LOVE-wise. Her existence was a crime in itself." Her eye showed me she had no fear. I shot her with another Gaster-Blaster.

10 hp, and she didn't bat her one eye.

"You're making a mistake. Do you really want to be known as a murderer? Even to Papyrus?" I didn't care anymore. It would all be reset anyway. I fought her with everything I had.

1 hp.

I hit her once more.

.5 hp.

How?!

She stood in front of me, and gave me a shit-eating grin.

"I'm not afraid of you. Not anymore," she said. I hit her one last time, and watched as she crumbled into dust.

The tears that welled in my eye-sockets finally spilled, and I was at (Y/N)'s side just as her soul shattered like glass.

Why did it have to be her?

(Y/N)'s P.O.V.

You were in what looked to be a dark room. It had no lights, yet when you looked down to feet, you could see them perfectly, as if they were in a spotlight.

"What is this place?" You asked yourself. You hadn't expected somebody to answer.

"It's the RESET plane. All anomalies in the underground are mostly caused here," a young girl spoke in the darkness.

When you looked for her, you couldn't see her. That is, until you looked up. She hovered above you, giving what seemed to be a purple glow.

"Salutations, (Y/N). I am Emily," the girl said.

"H-how do you know my name?" You asked, your voice quivering.

"I never thought I'd say this, but I've been hanging around in your mind. I just watch what's going on when I'm bored," Emily answered.

"I have a girl in my head. Huh. I should really be surprised about this," you said blankly.

Emily decended, having her eyes parallel to yours. On closer inspection, they were a bright shade of lavender.

"Your eyes are purple!" you exclaimed.

"Oh thanks Captain Obvious. I certainly didn't know," she said, rolling her eyes. "I have Alexandria's Genisis. I thought you would have it too, but I guess I was wrong."

"What's Alexandria's Genisis?"

"Look it up after you go back. The author doesn't feel like explaining it," She replied.

"Go back? Author?- Excuse my profanity, but what in the fuck are you talking about? I died." you reminded her.

"Press continue. If you have enough determination, you can go back in time to do stuff again. You obviously have enough since you're a sorceress," Emily told you. "I wish I was lucky enough to do that. I only know about RESETting, I can't do it though."

"Why do you like breaking the fourth wall?" You ask.

"Because I can. Now go back out there and save Frisk."

Emily pushed you to a yellow button that said 'continue'. You accidentally press it trying to stop yourself from face-planting into it.

The darkness faded to white.

Hey guys! I tried to add some comedy and if you couldn't tell, Emily is kinda a self-inserted OC. She'll break the fourth wall like how Asriel breaks barriers. If you didn't look up Alexandria's Genisis, it's actually a genetic mutation that, if you didn't figure it out, a person's irises to be purple. People who have it don't grow any hair except eyelashes, eyebrows, nose hair, earhair, and the hair on their heads. Women who have it don't have periods, but can have babies if they wanted to. This is why I didn't want to explain it earlier. Byee! :3
