You were a butler at the Elliot manor. You had the misfortune of coming face to face with Cyn, a child you thought was just like you... but, she wasn't. You now have in front of you a massive mechanical centipede with claws and large camera-like eyes with Cyn's body merged to it. She grabs you, lead you to a basement and throws you a chair.
Cyn : "Let's delete those memories one, more, time."
She takes an ice pick and sticks it in your head. It was supposed to make you lose consciousness and erase your memory but it doesn't work. You feel everything she's doing to you, you want to scream but you can't, as she starts to carve up your stomach. She's tearing off your hands and legs and replacing them with new ones. She's completely changing your body. The pain is unbearable, but at some point, you pass out.
You wake up in a cold and snowy place. With only one word in mind: 'KILL' You see two of your friends with you. One is U. She now has strange legs, but she kept her hairstyle, bangs with a long ponytail. The other, R has changed a lot too but less than U. He kept his haircut too.
U : "Oooh... wh-what happened ?"
R : "I feel like I forgot something..."
U : "Anyway... get ready for the next hunt !"
R : "Yeah !"
