In the early 1990s, experiments were carried out secretly in Japan. Two different methods were used in the experiments. One method involved forcing stress upon expecting parents and when the baby was born they would develop the baby's mutations and special abilities. The other method involved birth for babies with the abilities of animals and insects - the special abilities were derived from gene manipulation. Subaru, Saya and many others were born from those experiments.
