Aoi Yamada

Met during Otoo’s quest to find his lost wife, this mysterious sixteen-year-old girl eventually settles into the Wagnaria attic as a trainee waitress. Although she possesses immense self-confidence, her disruptive behavior at work frequently earns her reprimands from the staff, particularly Souta. Despite her frequent clashes with him, she occasionally listens to his advice. Driven by a deep longing for domestic stability, she even attempts to be adopted by Otoo, whom she views as a perfect father figure.
