Two different methods were used in the experiments. One method involved forcing stress upon expecting parents and when the baby was born, provoke the baby into mutations and develop their special abilities. The other method involved birth to babies having abilities of animals and insects. The special abilities were derived from gene manipulation. Subaru, Saya and others were born from those experiments. Subaru (Masaki Okada) possesses incredible strength and vision. Saya (Riko Narumi) possesses super hearing abilities. They both grew up in the same facility. They work for Koichiro Watase (Tsuyoshi Ihara) who is the senior Vice-Minister of Foreign Affairs and has lofty ambitions as a politician. Koichiro Watase then orders them to find the runaway daughter of a powerful politician. The runaway girl has in her possession a secret file. Subaru, Saya and others become involved in the slaughter group "Ageha." The group is led by Manabu (Shota Sometani). Based on the novel "Strayer's Chronicle" by Takayoshi Honda (first published April 5, 2012 by Shueisha Inc.).
