The truth is, Renko. Japan has a top-secret program of lifelike androids.

Faced with generational shrinkage and the harm that the lack of similar-aged peers might cause to societal development, the government ordered android "Classmates" from other countries, all very hush-hush.

Faced with declining birth rates in their own future, many countries decided to collaborate in order to gather sample data.

Without the people in class with these "Classmates" ever knowing.

You expect me to believe that sci-fi...?

Actually... Only about half as many people came to our class reunion a while ago...

Could it be...?

Yes. Some of those people are probably still in school.
