The following Matoki have been selected to travel to Earth: Shishimato, Tatsmato, Kekemato, Jokomato, Dadamato, and Totomato.

These six will spend time gathering information for a case study based specifically on human behavior. They have chosen six college students as case subjects for the reasons as listed. They are more developed in age, reason, and maturity but still have yet to figure out the basis of life. Each human they have selected appeals to certain behaviors and emotions that the Matoki hope to learn about in depth during their stay on Earth.

However will the involvement of two girls close to the chosen six humans help the study or confuse it in ways the Matoki never saw coming.
