He looked into the eyes of Kuhaku, which Gren had referred to as Shiro.  From what Abel had heard, it was his last name, but the idea of someone preferring to be called by last name was not alien to him.

Kuhaku Shiro is a Japanese name and while I can't speak for Hari this means that most likely Kuhaku is his surname and Shiro his given name. Calling people by there surname in Japanese culture is not uncommon but is generally reserved for close friends and family members.

Not that I'm asking you to change anything, that is a mistake that very likely would be made by the characters in the RP, just reporting data.
