Don't Let Me Down ( A Supernatural x Tokyo Revengers story)

I was the younger sister of Sam and Dean Winchester. Sam and I were born as twins. I reincarnated last minute, so Mary and John were surprised when I followed Sam out of the womb. I was also fed demon blood by the Yellow Eyed demon, however, It didn't affect me the way it affected my twin. I grew up training in various fighting styles and I often went hunting with dad and Dean, or they left me behind with Sammy. I didn't mind at all. But then I ended up in my favorite anime, and fell in love with my fictional crush, who isn't so fictional anymore
