(SO SORRY THAT IT'S LATE, MY DAD IS BEING STUPID AND IS FORCING MY BROTHER AND I TO GO OUTSIDE, NO MATTER THE WEATHER!!!)
     I woke up in a room(I know, very specific). 'I thought I fell asleep on the couch? Hmmm...... UGH, SANS!' I sat up and recognized the room as Sans's room. I jumped out of his bed and exited his room. I leaned on the railing and looked at the door.
     "3.... 2..... 1....." I muttered under my breath, then there was a knock on the door. I smiled in satisfaction.
     "Coming!" I heard Sans say as he teleported and opened the door. "Hey, Toriel and Asriel, come on in!"
     They said their greetings and Sans and Toriel started making small talk. Asriel started looking around, as if he was looking for something. I looked up at me and smiled. I giggled and put a finger over my lips, as if to say, "sh!" Toriel laughed, probably at one of Sans's puns. Asriel pretended like he didn't see me and Toriel and my boyfriend said their good-byes. Asriel and Sans sat on the couch and started talking about the test on my soul yesterday.
     "Is Y.N still asleep?" Asriel started.
     "Yeah, it must've tired her out quiet a bit. I still don't like that she has to do the same test as yesterday, today." While Sans was talking, I snuck down and behind Sans.
     I hugged him from behind and said, "Why is that?" He jumped a bit. Asriel smile widened, I rolled my eyes and sat down next to Sans.
     " 'Cause you're fighting Undyne to test different attacks on the soul! Yesterday, it was with Toriel. But Undyne is really powerful!"
     "HEY, THAT'S MY MOM THAT YOU'RE TALKING ABOUT!" Asriel yelled. I tried to stiffel a laugh.
     "Still," Sans said, "It's dangerous, and Y.N was nervos and scared!"
     "Yyyeeeeaaahhhh....." I idmited
     "Mmmmmmhhhhhhh~" Asriel teased.
     "Uggggghhhh! Asriel, give up, we're not going to be a thing, we're just friends! Sorry, not sorry, for sinking your ship." I crossed my arms.
     "Wwwhhhaaattteeevvveeerrr...... You two are going to become a thing! I know, maybe not this year or next, BUT IT WILL HAPPEN!!!" I smiled.
     "Eh, you never know." I said, looking at my watch. "Sans, Asriel, it's time to go."
     Sans teleported Asriel, him, and I to a secret part of waterfall, where we would meet Undyne and Alyphs. We arrive to see them kissing. Sans whistled, (we-wo kinda whistle) Asriel was clapping, and I said, "WOA-HO-HO-HO! WHAT DO WE HAVE HERE?" While rubbing my hands together in front of my face, smirking and staring while they pulled appart, blushing.
     "YOU SAW NOTHING, I SWEAR TO ASGORE, IF YOU TELL ANYONE!" Undyne yelled.
     Alyphs was a blushing mess, hiding her face in her lab coat. "Hey Undyne, at least you get to take this out on me." I said, smirking even wider.
     "OH HELL YEAH, NERD! I CANT WAIT TO SEE WHAT THAT SOUL HAS PLANNED!" She smiled a toothy grin as we entered the battle.
     My soul came out and it was glowing more than yesterday, I was fill with DETERMINATION. I'm ready to battle.
     "O-Okay, Y.N, grab y-your s-soul and tr-try to pull s-something out!" Alyphs yelled.
     I grabbed my soul, and before I was able to reach to try and grab something, Undyne said, "Hey, whatever you pull from it, you can try to hit/hurt me with it." I nodded. I went to reach to my soul and a handle appeared on my hand, but the rest of it was in my soul. I started pulling the object out of the soul, and it eventually came out. I looked at it, it was a double-bladed Scythe. The handle was in the middle and it had at least a foot and a half of a black pole ejecting out of each side of the handle; at the end of each pole, there was a foot-long, curved, (f/c) blade. Sharpened to the point. The blade in the top was facing to the left, and the bottom blade opposite. It was light, not what you would expect it to weigh. I tilted it to the side as I examined it.
     I held it in my dominant hand and then raised it straight in front of me, and it transformed into a bow, the same size. I knew how to use a bow, and I was specialized in using a scythe, this was going to be fun! I transformed it back into a Scythe and charged at Undyne in an instant.
     I raised it above my head, jumped while still going toward Undyne, and once I slowed and was above her, I brought my scythe down. She blocked it with her spears, and the recoil knocked me back a few feet. I was still on my feet, and gust was trailing behind me. She came at me this time and I dodged, but she turned and thew a wall of spears  at me. I raised my arm in defence, and prepared for my HP to drop. It didn't drop and I looked at my arm, a (2/f/c) clear shield was blocking the attack. I put my arm down and the shield dissipated. I ran at her and she moved, I kept running until I reached a wall, the walls in here were rounded so I could easily running across the wall.
     She threw Spears at me, but I was faster. She kept throwing them at me, and I kept running until smoke filled the battle field. "WHERE ARE YOU?" She shouted. I could see her yellow eyes piercing the dust. I sneaked behind her and turned my weapon into a bow. I somehow summoned an arrow made of diamonds. I readied my bow and waited for the smoke to clear. She was standing right in front of me and all eyes were on me. I had a smirk on my face, and the tip of my arrow was aimed at her nose. She laughed and said,
     "Heh, good move, but I'm not in check mate, I'm just in check, and I have one move."
     I tilted my head and raised an eyebrow, smile faltering. Spears rose from the ground right in front of me. My eyes widened as my shield rose up and captured my body in an (2/f/c) orb. This took a toll on my HP, leaving me with five HP. I fell on the ground, and in attempt to stand up, there was a spear that went through my chest. My bow and arrow disappeared from my hands. The battle ended and everyone clapped; but...

      I don't think Undyne knew my HP was at five, because now it was at 0. The spear was still impaled through my chest.
     "UMMMM... Y.N?" Undyne said. Everyone stopped congratulating Undyne.
    "Uhh... Y.N, this isn't funny, stop playing." Asriel said. I lifted head up slowly, and I saw Sans's prin prics were gone in both eyes, not even a spark. Blood was rolling from my mouth, to my chin, then dripping onto the ground. Undyne, who was just looking over her shoulder, turned around wide-eyed. My head was dripping down every-so often, but I kept bringing it back up.
     "Y-Y.N?" Alyphs stuttered.
     I let go a breath that I was holding in. My eyes were were focused on Sans. He teleported right in front of me. He held my head because it started to falter, again. He brought up my soul, and saw my HP. Blue tears started to form in his eyes.
     "Y.N, don't you dare leave me here...." my eyes started to water, I wanted to respond to him, to tell him I'm sorry for everything that Chara did, I wanted to feel his warmth one last time; to kiss him on the teeth and never stop telling him, "I love you." That's what I was going to say when I went to bed tonight. I was going to tell him I loved him, I wanted us to get married and grow old together. I couldn't let him fall back into the sad state he was in for so long.
     Tears rolled down my face as black spots started to grow visible in my vision. I had one ounce of strength left.
     "Sans?" I said under a whisper. He looked into my eyes as the tears started to fall from his eyes. "I love you...." I let out my final breath as I said these words. And, death grabbed me in a cold, dark embrace. I stayed like that for, what felt like, a couple minutes. But in this void it could be hours or days that went bye.
     But..... then there was a light, so dim and so far into the distance. I could feel what seemed to be ground beneath me. I wanted to see Sans again. No...... I needed to. I LOVE him, I won't let him go. I ran, I ran to the light, because I knew. White, was life; while black, isn't death nor life. Just a void. I reached the light, I looked behind me and I saw the darkness pull away from my body. I turned forward again, facing the light that grew lighter and brighter than anything I had ever seen. The light started to consume me, and a tear of joy rolled down my face. "I'm coming home, Sans. I LOVE you."
