Nanashiro Nanami♀

Nanami is the third-highest ranking maid of the Nogizaka family, and she usually helps Hazuki with her work, but is more commonly found alongside Mika helping and joining in on her spying missions. She has a friendly personality and smiles a lot, though also has a wicked tongue. She is seen wearing sunglasses often. Like Hazuki, she also often appears out of nowhere, though holding a large hammer that looks like a meat tenderizer for a defensive weapon. She has a habit of driving extremely fast (she drives the family Rolls-Royce Phantom like a WRC driver, though she sometimes drives the other Nogizaka limousine), but Haruka just states she is a great driver when one is in a hurry.
