Nikki Cherryflower works in the Department of Floaters with Sergio Turbo and Corolla. She is a badfic clone of Sakura Kinomoto who ended up in HQ by way of a plothole, and has been recently implied to be from the same fanfiction Sergio is. (Neither of them seems to be aware of it, though.) She retired in late 2012 after the events of the Blank Sprite incident, but still gets involved in PPC happening every now and then.
