Hakuouki artist question!

Who was the original artist for the game series "Hakuouki" (A visual novel known as an otome)? I know of Kazuki Yone (I wanna say her, but not sure.), Hyakka Ryoran, and Tsuisou Emaki (I'm pretty sure Emaki isn't the original artist). I wanna buy some art books, but I wanna make sure I'm buying the original artists work.
