Athena;Reborn

An unofficial spin-off of the anime "Terror in Resonance", "Athena;Reborn" takes place after the events of the original series, and follows investigator Shibizaki Kenjirou as he tries to fulfill the dying wishes of teenage terrorists Nine and Twelve. As he tries to shed some light on the mysterious Athena plan and ultimately locate the facility where it all took place, an unexpected adversary seems to stand in his way. This elusive figure not only takes on the namesake of "Sphinx", the terrorist duo who shook the very core of the country just months before but also threatens to repeat the past in order to commit a mass culling of the nation.
