Determination (Sans X Reader)

•Chapter 1•

Y/N POV

It's been a few days since my younger sibling, Frisk had gone missing. My mom was starting to get worried and so was I.

I decided to go somewhere Frisk and I always sat around and talked.

Mount Ebott.

There were many beautiful yellow flowers growing everywhere. I walked around, hoping to find them.

"What the fu-" I said as I tripped on a dead tree root and fell into a big hole. How did I not see that? I really need to pay attention to my surroundings.

I hit the ground a couple of minutes later, but it didn't hurt as much as I expected it to. I landed on a bed of flowers.

I walked around and saw a pile of dust as well as two halves of a bright white broken heart.

I picked up the heart halves and put them together. I saw Frisk with a knife in their hand, standing adjacent to a frog about their size.

What was Frisk doing? I wondered.

I got my answer a few seconds later when I saw Frisk stab the frog.

I shook myself, the vision ended, and there was a the same frog I was in the vision, right in front of me.

"(Ribbit, Ribbit) Hello human. I am a Froggit. Thank you. There was human that came and destroyed everything," the Froggit informed me.

Frisk.

"Human, please do to the other monsters as you did to me. Bring them back."

"I will," I promised, not noticing the tears falling down my face. Why would Frisk do something like this? I couldn't believe it. I had to find them and stop them.

I brought back several monsters like Whimsun, Loox, Moldsmal, and a few others. I reached a cozy looking home.

"This is Toriel's home. Please bring her back..." the first Froggit I brought back begged of me. "Goodbye, human." The Froggit hopped away.

I entered the home and I felt a bit uncomfortable. It was really quiet.

I let out a deep breath before looking for the broken heart.

It was nowhere to be found on the first floor, so I went down to the basement. I was greeted with a long purple hallway. At the end was a huge door of the same color as the hallway. There was a pile of dust as well as the broken heart. I picked it up and saw how Toriel died.

Frisk got Toriel to trust them, but at the last minute, Frisk killed her. She looked so disappointed and hurt.

"To think I was worried you wouldn't fit in out there. Eheheheheh. You really are no different than them!" She said weakly. She let out a small weak laugh that sent shivers down my spine. She then turned into dust.

I gasped as I was brought back to reality. Toriel stood in front of me.

She hugged me. "Hello my child." I hugged her back. Once I let go, she let go and asked "Why are we down here?" Clearly she had no memory of what happened with her and Frisk.

"I don't really know," I lied.

"Let's go upstairs." Toriel walked in front of me and the two of us went upstairs.

"I have a room for you to rest in, if you need it," she offered.

I accepted. but it would only be for tonight since I needed to get to Frisk.

Toriel made a cinnamon and butterscotch pie. We sat at her dining room table and ate it.

"Thank you for all of this, Toriel. But I'm going to be leaving tomorrow," I trailed off.

She looked a bit hurt "Why? Is there something wrong?" she asked.

I explained everything that has happened since I fell earlier today. She looked a bit sad, but knew I was leaving for a good reason.

"Alright," she said. "Get your rest. You've got a big day ahead of you." She smiled at me and I smiled back.

I went into the guest bedroom of Toriel's home after putting on a big t-shirt that I was given to sleep in. As soon as I hit the mattress, I fell asleep.

"Howdy! I'm Flowey! Flowey the Flower!" I saw a talking golden flower in my dream.

"Why are you trying to save them?" it asked. I opened my mouth to respond, but nothing came out.

The flower's once smiling face turned into a more creepy one. "D o n ' t     y  o u     k n o w   t h a t    i n   t h i s  w o r l d        i t ' s   k i l l   o r   b e   k i l l e d ?"

I jumped awake right before I almost died in my dream.

I decided that it was time for me to get up and go. I went to the bathroom to take a shower. Toriel had given me another set of clothes to wear so I wouldn't have to wear the clothes I wore yesterday. I put on the white shirt, ripped black jeans, black sneakers, and red scarf. I decided to just tie my hair in a bun. I exited the bathroom and Toriel greeted me in the living room.

She gave me a (f/c) bag with a container of butterscotch pie, a cell phone, and a few bandages inside.

"By the way, I never got your name, my child. What is it?" she asked me.

"It's (y/n)," I told her.

We walked down the long hallway once again and when we reached the end, she hugged me.

"Alright, (y/n). Good luck."

"Thanks Toriel." Honestly, I was going to miss her. She reminded me a lot of my mom. But I have a mission to accomplish.

I opened the door and walked out.

Knowing that you are one step closer to achieving your goal, fills you with DETERMINATION.
