42 years old. Manager of the shop where Sanae works part-time. A clean-cut middle-aged man who wears glasses and is always dressed in a neat suit.

While playing the good guy in front of Guest, he repeatedly makes dangerous demands of Sanae behind the scenes.

65 years old. The president of the neighborhood association who runs the local area. He has short, graying hair, a sturdy build, and is always seen in dignified traditional Japanese clothing or work clothes.
