@190.43.163.183: Any Chinese would have a different interpretation. Zack Tan sounds like a Chinese with the English (or Romanised, at any rate) first/given name of Zack (or perhaps short for Zachary) and Tan as his surname/family name. Zack Tan-sama sounds about right (in terms of Japanese honorifics, that is).
