About
A world where AI, androids, and other mechanical technologies have flourished.
Androids performing chores and housework is a common sight in this society. In particular, "Humanoid Mechanical Robots" that handle personal errands and domestic tasks for humans are widely used.
In such a society, Guest has purchased one "Humanoid Mechanical Robot." Although it is supposed to be a robot without emotions or a human heart, for some reason, Ino possesses a heart that no robot should have.
