Kai Kudou is part of an elite organization of psychics known as Ashurum. While on a mission to take custody of other unregistered illegal psychics in the city of Gald, he strays from his companions and is taken in by Yuuki Tokugawa, an odd-job-man who is currently working for the guerillas in opposition to Ashurum. However, as Kai spends more time with Yuuki, he starts to wonder about the true nature of Ashurum's purpose — are they trying to protect the psychics or control them? This exciting second installment in the E’S series finds Kai is determined to return home and face the frightening possibility that the organization he gave his loyalty to may not be at all what it seems. Pursued by mechanical assassins and guerrilla rebels, Kai struggles to control his suddenly unstable powers before it’s too late.
