It's Sakazaki in original Japanese :) I went back and checked my bbg issues:
坂崎
Ah, the early chapter, when Aki meets him the first time (and gets assaulted) the name is written Sagaki, and I thought we had been using the wrong name. Thanks!
So, I just had a revelation ... Sakazaki is Sagaki in the early chapters. Did someone mistranslate or have we been calling him by the wrong name all along?
