"I don't actually know what my name would've been before. My memories of my birth parents are hazy at best, and I don't give a shit about them so I never learned more." Byakuya had offered, but he turned him down. "Byakuya was more than enough."

He should probably explain. "He wasn't petrified like I was, so he died some 3700 years ago." Not that it made it any better, but he didn't have time to cling to grief.
