The House of Undertale AUs

Chapter 16

Y/N's POV:

I was actually happy the next day.

Chara had explained to me that she killed the three bullies that hurt us. At first, I was concerned and mad, but she said she asked them if they had parents or not and then led them to a dark alley and killed them.

Even though the bullies were gone, I still withdraw me and Frisk out of school. I would be too busy with the AUs and I don't want Frisk going to school alone. Chara offered to go but I told him maybe next year.

Gaster gave me a sweet new toy, sort of. The first one was a tablet, which was already on. Gaster explained that the tablet has a lot of info about the AUs from Ink.

There was a section for a lot of AUs. There were stuff that I knew already knew and even stuff that I didn't know about and the characters' habits. For example, UF Sans like to torment UF Frisk at 3:00 on Tuesday.

Wait, what?!

I checked the time on the tablet. It was 2:50. And if my memory was correct, today is Tuesday. Before Gaster could show me the next gift, I already rushed out of my secret lab and into the house. Everything was pretty normal, so I doubted if the tablet was telling the truth.

"Actually, it's true," Gaster informed me. "Basically, you could learn more about them and know how to take care of them better."

With a sigh, I went upstairs to Underfell's room. Looking around, I realized that the room was exactly the same as Undertale's, except everything was mostly black and red, which was basically their favorite color.

Anyways, I decided to climb onto UF Sans'a bed and wait for him. To past time, I started reading the notes of the tablet for Undertale.

UF Sans's POV:

I looked at the time. It was 2:55 and I was busily arguing with Flowey. That flower is f***ing annoying!

"Where's Frisk?" I asked again. Flowey hissed angrily at me.

"You won't be able to find her," he said. "Because I hid her somewhere where you can't find her for today."

I was about to argue back when I heard a voice say, "Flowey? I got tired of hiding."

"No!!" Flowey cried, but my eyes widened with surprise and I smiled.

"There you are my little pet," I chuckled. I teleported next to her, picked her up, and teleported to my room, leaving Flowey at the table who was yelling at me.

I rushed into my room and found Y/N already there reading on some sort of rectangular object. She didn't look up. Instead, she just said, "You're late by a minute."

Confused, I looked at the clock. It was 3:01. How did she know about me always doing this? I sometimes skip this so no one knows when I'll do it.

My question started to form. "How—"

Before I could say even two words, she showed me what she was reading. It showed facts about all the AUs. "Number 7 on Underfell- Sans likes to torment Frisk at 3:00 on Tuesday," Y/N said softly.

I started to sweat a little. Frisk got out of my grasp and climbed into my bed with her dimensional sister.

"How do you know if that's true facts?" I asked.

"Because Ink gave me all of this information," she replied smoothly. My hand twitch.

"Get out," I growled. "This is my room."

"This is my house that I made," Y/N sighed, still not looking at me. She was stilling reading and patting Frisk's head at the same time. Frisk was cuddled next to her, falling asleep.

I growled in frustration. Y/N sighed one more time and finally looked up. "Fine. How about this? We play a game and honor our agreements and bets. For example, if I win you cannot complain about me being here again. And you can't torture Frisk ever again. But, if you win, I won't be able to come back here and won't be able to complain about you torturing Frisk."

I thought about this for a moment. It seemed fair.

"And, you get to make up the rules for the game," Y/N added. This, I agreed to.

"Okay then. The same bets for what you just said," I declared. "Except for me not able to torture Frisk again, I'm gonna change that to you are able to intervene, but you can't stop me entirely."

"Deal," Y/N said in a very bored voice. I grew a bit angry. Why would she be bored?

"Okay," I said and hesitated. What game should we play? I looked outside and saw some birds standing there outside.

"I have an idea. Let's play a game that's all about luck," I chuckled. Frisk looked up and at Y/N with a worried expression. I couldn't help but blush. Frisk looks so cute when she's like that!!!

Y/N patted her head again. "Don't worry. I'll be fine." Oh, no you won't.

We headed outside with Frisk tagging along. I grinned and turned around. "Okay, how long do you think those birds will stay there and then fly away?"

Y/N sat down on the rocky floor. "Okay, that's the game. You can go first."

I looked at her in surprise. Truthfully, I had no idea how long. So, I gave it my best shot. "Er, maybe 30 seconds?" I said it more as a question than a statement.

Y/N stood up rubbing her head with her left hand. I saw a small object in her right hand. "I say..." she went into the same position that a baseball player would do before throwing a baseball.

"3 seconds!" she cried out and threw the object in her hand. It was a stone from the ground!!

1 second- the rock was flying in the air.

2 seconds- the rock hit the ground next to the birds.

3 seconds- the birds went flying into the air.

I looked at the flying birds in shock. "Th-that wasn't fair!" I argued.

"Huh?" she raised an eyebrow. "I'm pretty sure that you didn't make any rules even though I told you that you can make some." I made my hands into a fist.

Then, I felt a tug on my jacket. "Sans, you promised," Frisk whimpered. I groaned silently. Then, I felt something on my cheeks. I looked to see Frisk... KISSING ME?!

My face immediately went warm. By instinct. I pulled up my hood from my jacket and put it over my head in embarrassment. Frisk's laugh filled my ears. I even heard a tiny little giggle from Y/N.

"Alright, love birds," Y/N tried to say with a straight face, "we gotta go before anyone sees that we're gone."

"Okay," I grumbled, still upset that I lost the game. It was totally unfair!! But then again, I didn't make any rules, so it doesn't counts as cheating.

"Don't be such a bad sport," Y/N sighed. I looked at her in surprise. Did she read my mind? I doubt it.

We were walking back to the back door of the house when I heard Y/N mutter to herself, "Thank god I read that manga on my tablet. Thank you, Sora and Shino from the anime, 'No Game No Life'."

Hello everyone! I'll just say something about myself. I LOVE anime!! It's so awesome. And when I watch a really cool anime, I'll sort of add the ability from the anime's character into you! Or maybe someone else. Like how I added Shira's smartness into you and how he likes to keep track of the rules and what he's gonna do. Instead, I put notes of the AUs on the tablet.

Sometimes when I say something, I won't understand myself...

This part where you are like Sora and Shiro is only on this chapter. I might do it again but there's a probability of 1/1000. Hope you guys all like this story so far!!

Peace ☮️
