Undertale: Blue: Black and Blue

Chapter 4: Red vs Blue

"Let's see how well you ca-ca-ca-can deal with your si-si-si-sister. Can you stri-stri-stri-strike her down? Or will you gi-gi-gi-give up?" Error asked me as I backed away from Red, who had her knife out and pointed towards me. "Red... Stop... This isn't you..." I told her, but she kept walking towards me. "I'll see you two when you-you-you-you're done." Error said as he walked away. Red kept staring at me with cold, dead eyes as she walked towards me. "Please, sis, I don't want to fight you..." I tried to convince her to stop, but nothing worked. It was her, I knew it was. I don't want to kill her, it's the last thing I'd want to do, but...

I have no choice. I thought to myself as she finally stopped moving and got into a fighting stance. "Sis... I'm sorry..." Those were the last words I said before she swung at me. I blocked it with one of my swords and swung the other, she jumped to dodge my second attack and kicked my second sword out of my hand. She threw her knife on the floor and grabbed my sword before I did. We then kept swinging at each other, our swords clashing with each swing. With the last clash, we struggled against each other. She kicked me out of the struggle and sliced at my chest, making a mark on my chest. I clenched my teeth in pain, holding my chest with my left hand. She then sliced at me again, bringing the blade down at my head. I blocked it with my sword, looked up at her and used my wings and flew into the air. I then flew down as fast as I could and sliced when I got close, making a huge slash from the right side of her chest down to her left leg. She fell down to the ground immediately, writhing in pain, crying and yelling for help. Tears ran down my face as I heard this, and I walked up to her. When I got up to her I looked over her and noticed she was staring at me. She handed me my other sword and a strange tape. In her dying breath she said "Blue... This tape tells you what happened to me... Please... Watch the tape... And, do me a favor... Kick Error's ass for me..." She looked at me as a held her in my arms. "I will sis... I will." I told her, trying to hold back my tears. "Thanks... Bro..." She said, before she closed her eyes and let out her last breath. I held her in my arms when she died. I carried her through the portal that led out of Error's dimension or whatever it was all the way back to Snowdin, where I buried her next to our house. I went back to the Ruins and walked back into the portal. When I walked in, there was a T.V and VCR. I put the tape in the VCR, I was going to find out what happened.

"God where's Blue? I've been bored all day..." Red said as she was sitting in a armchair. There was a knock at the door. "Who is it?" Red asked, hoping it was Blue. "An old friend of Blu-Blu-Blu-Blue's." Error said. When Red answered the door, Error grabbed her and teleported away. He then tied Red up and tortured her. He then put a device on her, forcing her to listen to Error's orders until she was killed or the device was destroyed.

"So that's what happened... Error you bastered, I'm coming for you." I said to myself as I walked toward the door Error walked through. After I walked in I was greeted by Error, and he freed the friends I brought with me, but not Fig. "So I guess you could... That makes you more heart-heart-heart-heartless than me!" Error said. Chanas, Magic, Artist and Black looked at me and noticed I was crying, but I stopped when I noticed they saw me. I looked up at Error, who was spinning one of his string-like fingers like a lasso. "You know, I-I-I-I'll give you a free shot. Make it worth it." Error said. Chanas, Magic, Artist, and Black got into a stance with me, and we all charged at him at one.

This is it. I thought. This is where it ends.
