The House of Undertale AUs

Chapter 21

Sans's POV:

"Woah! Who's that?" I asked, pointing to a picture of another me. He looked a lot like Gaster and me at the same time. It was a week since the incident with Jessica. She always looked at me and Y/N fearfully at school. Fortunately, me and Y/N made up, even though she had no grudges against me. I was completely the opposite. I kept on apologizing to her about my actions but she laughed and said that it's fine. I think I'm annoying her, actually.

"That's Sans," Y/N rolled her eyes. "He's half Gaster, half Sans. From..." she checked her tablet. "From Echotale. Papyrus is also half Gaster."

My eye went blue. "So, they'll be coming here too, right?"

Y/N shook her head. "Gaster—I mean, Ink, told me that they won't be attacking there."

"Why?"

Y/N turned towards me, criss-crossing her legs on my bed. I turned slightly blue. She looked cute when she's serious.

"If you were a bad guy, and the choice you could make was either attacking these AUs or attacking an AU that had you and your brother that's half of your dad, what would you choose?" Y/N asked, leaning towards me. I thought over it.

"Good point," I concluded. Y/N smiled, which made me leaned towards her as well. "A very good point."

And then, the door banged open. Me and Y/N immediately jumped apart.

"Oh, sorry," Ink said sheepishly. "I couldn't find you at your normal place so... I walked around. Were you..."

"No," Y/N said immediately. "We were... just reading on my tablet and looking through the AUs."

"Oh, ok," Ink said, not buying her story at all. He even actually rolled his eyes, that bastard. "We're going now."

"Where are we going now?" Y/N asked. Ink made a face, which meant somewhere unpleasant.

"The worst place I've ever been," Ink muttered. "And the worst place I've ever created. An AU called Underlust."

Y/N flinched and stood up. "Nope. Nope nope nope nope nope nope nope..." her voice faded as she headed outside, her arms raised up in surrender as she left.

"What's so bad about that place other than its name?" I asked, but immediately regretted it.

Ink stared at me. "You don't know? All that they're obsessed with is..." he shuddered. "Sex."

I immediately stood up. "They are not coming," I declared.

"Sorry, but we promised to save all Genocide AUs, like it or not."

Y/N finally came back inside. "When are we leaving?"

Ink looked at her weirdly before he burst out laughing. "I-I'm just kid-kidding with y-you!!" he shouted as he kept on laughing. "Y-You should've se-seen your face!!" I swear, he was genuinely going to cry, if we skeletons were able to do that. (A/N *too bad, you dirty thinkers. No sex for you*)

Y/N heaved a sigh. "Okay then. Where are we really going to?

"Outertale," Ink wheezed.

"Cool! And when?"

"As soon as you're ready," Ink replied, finally calming down. "And also, we have a new enemy."

"Who is it? Another Sans?"

"Yep," Ink answered. "It's Sans from Aftertale. He tried to teleport while he was dying because of Chara. Well, something happened and now that place is pretty much a time loop of Chara killing again and again. There's another Sans that has most of regular Sans's soul, but doesn't remember what happens that much."

"That sounds pretty tough," Y/N mused. "So, he wants to end all Pacifist so everyone could taste his bitterness?"

"That's about right."

"You better not get hurt again," I ordered Y/N. She looked at me as if I was crazy.

"Since when did I never get hurt?" She asked, and then grinned. "Don't worry. I'll be fine."

Says the girl who gotten herself a nasty gash so she could protect Frisk. Then again, I can never see her coming home without some bruises and some cuts.

Then, a thought came to me. I've seen her get so many cuts and bruises, but she never puts any medicine on it. And a few days later, it vanishes like it's been healed by an invisible person.

I asked Y/N about it, but she waved it away. "Don't worry about it Sans," she'll always say. But I do worry about it. A lot.

"What's Outertale anyways?" I asked her. In response, she threw her tablet at me.

"Look it up," she simply replied. "Alright, let's get going! To outer space AU!" And I didn't even know if she was kidding or not.

Y/N's POV:

I put on the ring for Outertale, which was labelled 'OT'. Once I put it on, I looked amazing (look at picture above but I'll describe a little bit of it). I had a purple sweater but my cape was awesome. Outside, it was black but inside was purple and had some other colors that made it swirl like a galaxy, which fits where I'm going, actually. I still had my two scars going up and down my eyes and the holes in my hand (which is still really weird no matter what), but I looked super awesome.

"Let's get going!" I cheered. Ink made a swirling white portal and I immediately jumped inside.

When I landed, I almost fell into space. I was standing at the edge of an asteroid.

"Y/N? Where did you go?" I heard Ink calling out.

"Here!" I yelled back. He came towards my voice and help me back onto the asteroid we were standing on. "So, where is everyone?

My answer was answered with a scream. Not exactly what the correct answer but it means that we have trouble.

Me and Ink quickly headed over to where we heard the scream. Boy, were we in for a surprise. There were so much stardust on the the ground that our footprints were shown. I saw OT Sans and OT Undyne fighting someone. Their starry bones and spear was no match for a lone figure's shining blue bones in the galaxy. I would've mistaken it for the regular Sans' powers but I knew better.

Aftertale Sans was here.
