{Warning: This chapter contains mature content, and goes full Yandere, This is also an alternate universe.}

You watched from behind a tree as your Senpai Rainbow Dash rode past on a skateboard that she got for her birthday. You managed to get a sneaky pic of the rainbow haired girl before running away, giggling and blushing. "Oh Dashie, I'll soon get you to notice me!" You said to yourself as you hugged the photo of Rainbow Dash to your chest before running into your house. After a few minutes, you finally arrived home and put up the photo on your wall, which had many photos of the rainbow haired girl. Many students knew about your little crush on her, your obsession for her had only grown along with your love for her as time went by. You held the rag-doll of Rainbow Dash in your arms as you lay on your bed and took a nap.
🔪Timeskip to Midnight...🔪
You slipped on a dark black outfit and jumped out of your bedroom window before running towards the rainbow haired girls house. You silently took several photos of your Senpai sleeping peacefully, completely unaware of your presence before your silhouette disappeared, meaning that you ran off into the dark night and running home. You killed your parents so that they wouldn't be able to stop you from eliminating your rivals, which was two years ago.

❤️The next day...❤️
Rainbow Dash walked down the pavement towards Canterlot High, it was very quiet and she didn't know why. "They're still probably sleeping." The rainbow haired girl said to herself as she ran towards the double doors and opened them, only to be greeted by a horrible looking sight. Corpses were everywhere, the thing that shocked Rainbow Dash was that she noticed the corpses of Sunset Shimmer, Fluttershy, Rarity, Pinkie pie, Applejack, Sci Twi and many other people that she knew.  "What's happened here?!" The rainbow haired girl said in horror before running towards Principal Celestia's office, only to see the older woman's corpse on the ground but the worst part was that she noticed you standing there, covered in blood and carrying a kitchen knife in your right hand. "I did all this for you Dashie." You said calmly, yet you had an insane laugh on your face as you slowly stepped towards the terrified rainbow haired girl. "Why are you killing the people that I know?!" Rainbow Dash stuttered in fear. You let out an evil giggle before pinning her to the wall. "Just to put things straight Dashie, you're mine!" You stated darkly. "Your my little dashie!" You breathed slowly.
