Nariko Nakamura was the eccentric and overzealous waitress at Voyage Burger. She worked as a 'Viqueen' and went by the name 'Yvette Valkeyrian' at work. This name is also her pen name for her Viking stories. She seems to take a liking to Ashley who, like her is a misfit and outsider and the two form a closer bond.

Nariko seems like a kind and innocent girl and she uses this to her advantage when she gets the 'Nuklear Intoxikation' crew banned from Voyage Burger. It is later revealed she isn't who she seems during the trip to Swanton as she is pining for another.
