Have you ever heard the song "Alluring Secret Black Vow"? It's a song by Rin Kagamine. I listened to this song for the first time in a while and thought, 'Hey, I wanna make a fanfiction with that storyline.' So here I am. :) Please don't think that I'm taking credit for this song, this story. I'm basically writing my perspective of the song and putting names with it and a little more details. The names I of course don't own either. Enjoy!
