Coffins Make You Crazy (undertaker x reader)

Unwanted Final Phase

|Undertaker's POV|

What I saw horrified me to no end. (y/n)'s once (e/c) eyes are now a demonic color. A mixture of purple, red, and blue. I stepped back. (y/n) looked at me with a menacing look but eventually, that menace turned to worry and fear. "U-undertaker. W-what happened to me?" She asked. I recomposed myself and went up to her. "You're going to be fine, dear!" I told her. "What's happened? W-where's Jane? I-I can't find her, I-I can't hear her!" She started panicking. I laid her head on my chest. "Shh. It's ok. Everything is going to be ok." I soothed. She calmed. "What happened?" She asked, once again. I took her hand and led her to the mirror in her room. She stood there stunned. No words, no movement, no (e/c) eyes. (y/n) suddenly drops the mirror. "H-how did this happen?" She asked. I looked down. "I'm afraid that I don't know." She ran outside and started pushing things aside and grabbing things. "What are you doing?" I asked. She raised a scalpel at her throat. "(y/n)!!!" I shouted. Before I could stop her, she stabbed herself. She screamed in agony. I pulled the scalpel out and checked her wounds but realized that the wound is already healed. "What?" I sat next to (y/n). "I saw these colored eyes in Claude and Sebastian before. I am a demon, aren't I?" (y/n) said. I gave a slow nod. Why? Why must Claude do this? He took (y/n) away from me. He... he... I ran to my room and slammed the door. That little demon! I'll show him. I felt a dark aura surrounding me. Undertaker. Jane. My sister. Take care of her. I shall help you fight. I detached my soul from hers to yours but this is only temporary. I am aiding you in killing Claude! That is a good choice. You are aware that I cannot be by (y/n)'s side at this moment, correct? She is a demon and I am a reaper. Of course. That is why I set my limited time to three days. You have a total of fifty-two hours now. How did that happen? I attached to you when you carried (y/n) but I couldn't talk to you because I was still partly within (y/n) and then you were off, after Claude. Fifty-two hours is a fine time! I raced to the Phantomhive manor. I'll need a little demon power first!
