Battle music is above ^(I would've chosen something different,but it was from Geometry Dash Meltdown,so it probably wouldn't fit in)

Chara began laughing maniacally and black knives started falling from the sky. I summoned a gaster blaster to block all of the knives,which it eventually broke and a knife tore a huge hole in my jacket. The knives stopped and I began firing gaster blasters,1, then 2, then 3, then 4, and finally, 5. Chara dodged all with ease and flew towards me,trying to attack,I avoided them and teleported behind her.

I summoned a long bone and tried to attack Chara with it like a weapon,Chara teleported away then came back and tried to strike me with her knife,but we clashed weapons. This is now like a sword fight. We kept trying to attack each other but our weapons kept crashing into each other,so when Chara tried to attack again,I teleported away and made it rain bones.

Chara tried to dodge,but some hit her because they were going down quick. She ate a legendary hero and some of her cuts faded away.  I used my psychokinesis to lift her soul up and slammed her onto the walls over and over again. I let her go eventually and I attempted to blast her with two gaster blasters. Before I could,Chara raised her hand and it was surrounded in a dark aura. The gaster blasters' eyes turned red and came towards Chara.

  Chara fired the blasters at me and I fired mine just after. Our beams crashed together and were struggling for power. I put in more power and so did Chara,we were equally matched at this point. Our beams exploded causing our blasters to break apart and we both were in the explosion which caused some damage to both of us. I was starting to bleed and Chara was already bleeding.

"I don't need food,"she shouted,"I can kill you without healing!" She turned her knife black and attempted to attack me,I dodged then my leg was suddenly restrained by a dark vine and white pellets surrounded me. Chara looked to her right and nodded. I looked and saw Flowey laughing,then the pellets came closer to me and I teleported away just as they were about to touch me.

Chara growled and slashed in the air. Red streaks were following the knife's path and as soon as an X shape was made,the streaks came towards me,one at a time,I avoided both and fired a gaster blaster. Chara teleported behind me and tried to stab my back,I teleported away and hit her with the long bone. Chara quickly drank a Starfrait and a few minor cuts faded away. "That was an exception."She said before teleporting away and appeared high in the air. I turned around and saw Flowey tried to attack me with large vines. I stabbed one with a bone and jumped back.

Damn it! I wish anyone could help me... I called for help...

"BuT nObOdY CaMe..." Chara grinned and slashed my face with her knife. I was starting to get exhausted,sweat was pouring down my head and I was panting. Chara slowly walked towards me and I kept firing Gaster Blasters at her,but she dodged every one of them. "Sansy? Why didn't you give me more of a challenge? You did worse than last time...you didn't even kill me...once."Chara said. "Yeah,I know,"I replied,"but that doesn't mean I can't stop you from wiping out the Underground. I swear to god."

Chara surrounded my right elbow joint with dark aura and looked back up at me. "That tells you that you have to do the promise,or you will die when you go to sleep,whether it's a nap or not...so...when I am trying to wipe out the Underground,you and Frisk have to defeat me,or you both die,she has a vine on her arm that says how many days left,I gave her it so she could be prepared. Make sure to read the number..." Chara said. I nodded then I woke up.

"Ow! Everything's hurting!"I shouted. "OH MY GOSH! HE'S FINALLY AWAKE!" I heard a loud voice,everything was blurry,but it looked like I was in...the hospital?
