In the future, with a huge decline in the birth
rate and the rapid development of technologies,
robots have taken on an extremely human-like
appearance. They are now "androids" with more
advanced, or at least equal, physical, intellectual,
and emotional abilities. For example, even the
androids are equipped with replaceable body
parts and no sensibility to pain. Still, being
socialised, they are emotionally able to feel the
trauma under assualt.
