Mama, formally Ayako Matsuzaki, is Ami Matsuzaki's mother. Though frequently heard addressing Ami offscreen, she remains physically obscured throughout the series. When shown, only glimpses like limbs or body sections appear at the screen's edge, reinforcing her elusive presence. Unaware of the AniYoko doorway or its trio of visitors—Iyo, Kenta, and Issa—she occasionally detects the real-world fallout from their disruptions, manifesting as domestic disturbances or shifts in Ami's conduct. Her narrative role centers solely on offscreen parental duties, such as summoning Ami for meals or daily routines. No expanded background, development, or role in other media exists. She functions solely as a peripheral offscreen presence within Ami's family life, without further exploration or personal storyline.
