Y/N's POV:

I frowned, looking at my test results. Why was this thing so freaking hard to make?!

"Man, I could feel how good you can control your temper," Gaster laughed in my head.

"Be quiet," I said and pushed his voice in the back of my head. I took a deep breath and tried one more time. This time, the heart amulet turned red, then black.

"I got it!" I yelled triumphantly. Then, the heart lock became half red and half black, the middle was that the two colors overlapped each other. With a grin, I put the locket on my neck. I could feel the looks that I had when I was Gaster!Y/N going away. Soon, I was regular old me in my old clothes, except for the fact that I still had Gaster in my head and his powers.

"Right, now what?" I asked Gaster.

"Now, you need to change into something black and maybe a mask like a ninja and wait for midnight to come," was all he said.

Frisk's POV:

Night, or at least what looked like night fell upon us. The only thing with light was our house and Grillby.

"Where is he?" I heard Sans grumbling. Papyrus and Undyne was making us some spaghetti while Grillby was serving some fries and burgers he saved from his place. Suddenly, I saw a portal from the window. Chara was next to me.

"Sans! He's here," Chara shouted. Everyone hurried to the window to see Ink.

"My god, he looks like Sans," Undyne muttered.

"His name is Ink Sans," I counter argued Undyne. She looked at me with surprise.

"Ink... Sans?!" I nodded. There was a knock and Sans opened it. Ink peeking inside and saw all of us at the window.

"Ready to go?" Ink asked with a grin. We nodded. He created a portal with his paintbrush. Ink went first and everyone went in. Sans, Papyrus and I went in last. Just as I was about to step in, I saw someone outside. He had a big knife that was cutting up the ground, making a red line.

I freaked and I pointed at him. Sans looked and he immediately pushed his brother into the portal.

"SANS? WHAT IS—WHOA!" Papyrus yelped. After he disappeared, Ink came back and looked at what me and Sans was staring at .

"Oh, no," Ink muttered. "Cross is here."

"Cross? Who is Cross?" I asked.

"Cross is Sans with a Genocide Chara in him," Ink told us. "He's very dangerous and with Chara telling him what to do, that's bad. We need to go. Now." Without saying a word, I went in. Sans and Ink came behind me.

We appeared in the middle of a village. I knew it because it was my village, where I onced lived.

"Where is she?" Ink muttered. I was confused. A couple of monsters were in the dark and we're waiting for someone? What if someone spotted us.

Before I could ask that to Ink, something moved in the front. Sans summoned some Gaster Blasters, or whatever he called them but Ink held out a hand. The figure came closer and I could see their features.

It was a slim person who is the same height as me. They were wearing a black coat, the back of it pretty long. They were also wearing black pants, black shoes, and there was a mask that covered her whole face except for her eyes and the bridge of her nose.

"Are they all here?" a female voice asked. Ink nodded, which told me that Ink knew this girl. She then looked at our group. "Here's not safe. Follow me." She went along, taking long strides. I had to run to keep up with everyone.

"Who are you?" Sans demanded, his eyes glowing blue.

"Keep quiet, Sans," Ink said in a hushed voice. "She said this place isn't safe. Once we take you there, you'll ask that question." Sans didn't look too happy but he didn't say a word afterwards. No one did. They were too nervous to say anything.

We reached a small house at the far edge of the village and some of the monsters frowned. "It's too small for all of us," one complained. The girl in black glared at it and the monster immediately took a step back.

"Go to the back door," she instructed. "Touch nothing and keep on following me." It didn't look like any of us wanted to be on her bad side, so we did what she said.

The house was very neat. It was almost like Sans' house but neater and no sock that had sticky notes of Papyrus telling Sans to pick up his sock. That thought almost made me giggle.

"We almost there?" Ink asked. The girl nodded and she flung open the back door. All of the monsters up front gasped in shock. I squeezed through everyone to see.

There was mist everywhere. No one could see even two feet in front. The girl spun around. "Alright, everyone. Wait here. And do not open the front door." She walked into the mist and disappeared. As soon as she does that, everyone immediately went separate ways. They all looked around the house.

"I thought that she said not to touch anything," Ink scolded Sans, who picked up a picture frame. Sans shrugged and didn't reply as he stared at the picture even more.

"Frisk? Is this you?" Sans looked at me and showed me the picture. I looked at it. There was me with three people. Two were adults, a mother and a father. I was in front of the woman and a kid who looked at me except her hair was longer stood next to me had her arm around my neck. She and I was laughing happily. We were in front of this house.

I gasped. Now I realized why this house was so familiar. This was my house. The village, the house, everything. It was my old life. So that girl is...

"You guys done messing with my stuff?" a voice asked. We all turned to see the girl. Her mask was off now and I saw her face. She had lighter brown eyes than me, the same length of brown hair, and she really looked like me. She was also wearing a heart locket, top half red and bottom half black but in the middle, the colors overlapped each other.

Finally, for some reason her clothes changed into a regular magenta jacket with a white t-shirt, brown pants and light blue shoes. That's strange. Did she change while she was gone?

I finally caught myself staring at her. But I almost laughed when I saw Sans staring at her. A lot.

"Hey, Sans?" I whispered. He snapped out of his trance and looked at me.

"Yeah kiddo. What's up?" he asked, a blue blush fading away from his face. I wanted to laugh but I didn't.

"Everyone," I straightened and looked at all of the monsters in the living room. "Meet Y/N. She's my sister."

Hey guys! I really didn't expect it to be this long. That's why once I finished writing I added 'Part 1' to the title. So, now you see how hard this was going to be when I get more AUs coming in. Phew.

Also, how are you guys liking this book? That's my daily question for you. Chat down below how you guys are liking this. Maybe make some suggestions for this. It could give me an idea if I ever get writer's block. Other than that, hope you're enjoying this.
