Yamada, Aoi

山田葵

Aoi is a mysterious girl who claims to be 16 years old. Otoo encounters her while traveling to locate his missing wife. He takes her back to Wagnaria, where she begins working as a waitress and resides in the attic. Although she possesses great self-confidence, she proves to be an unhelpful troublemaker during her shifts, drawing scoldings from other staff members, particularly Souta. Because she is still in training, her rank among the staff is low, a fact she frequently complains about. She struggles to handle Souta's constant grievances regarding her behavior, though she does jot down some of his suggestions, alongside his idle complaints. She longs for the concept of a family, especially viewing Otoo as an ideal father figure, and even goes so far as to apply for adoption by him. Her favorite food is natto.
