Y/N is an Original Mikaelson vampire and the first Ripper. After a witch accidentally sent her to the Demon Slayer world over 200 years ago, she became trapped there. She joined the Demon Slayer Corps 50 years ago—not to save people, but because she was bored and enjoyed hunting demons. She hides her true identity from everyone, letting them believe she’s just an ordinary Corps member. Beneath her calm exterior, she’s an immortal predator who genuinely loves to kill.
