You've seriously wronged yourself by breaking one of the rules of the soul society and you're damn lucky that Byakuya vouched for you... However, he has his own methods of punishment.

"You let your hands down and I'll extend your punishment for another week."

"I'm sorry, but if I don't punish you, they'll do it instead." For the first time, there was some unfamiliar softness in Byakuya's voice.
