Inspired a bit by a fic I'm reading and A Goofy Movie.
Lately, Ichigo has noticed he's been acting... weird. Nothign to do with Hollows, or Shinigami, Fullbring, or whatever. It's almost like his dad is posessing his body. In a moment of weakness, he talks to his dad about it, and Isshin gets a very serious look on his face.
"Ichigo, I was once like you. I was a motherfucking badass. Men quavered at the thought of messing with me. Ladies swooned when I walked down the street. But then, one day, when I became a man, I was filled with... urges. Strange urges, urges that seemed so gaddamn stupid I couldn't believe I was having them. But I was, and no matter how much I fought them, they always won, and grew stronger, and more frequent. Within a few short years, I had become the lovable goofball you see before you. This is the curse of the Kurosaki family, and now you too, shall know its touch."
"Wasn't Kurosaki mom's last name?"
"Not important. You're cursed."
