Riesling (リースリング Rīsuringu?), alias Leona Buchholz (レオナ・ブッフホルツ Reona Buffuhorutsu?)[1], is a Black Organization member who appears in The Darkest Nightmare.


Leona Buchholz works for the Black Organization, but is a german BND and an undercover spy that infiltrated the organization under the codename Riesling. She is listed on the Public Security Bureau's list of undercover agents as a spy and was found out by Curaçao, who wrote a message to Rum in order to make her die. Vodka threatens her to tell who are the rats. She was killed by Gin.


She is a patriotic defender of her country and will even protect others at the risk of taking her life, since she didn't reveal to Gin the names of other agents, Kir and Bourbon. She is courageous since she tried to escape Gin, even if she knew it was reckless.


She is a young lady in her twenties, with short blond hair kept loose, green eyes and lipstick. She wears a black jumpsuit when she was killed.



  • Riesling is the name of a white grape which originated in the Rhine region of Germany, where BND is served. It was used to make a white wine.
