Kai and Hikaru are protected by a corporation called ASHURUM, from a society that fears E's. ASHURUM is 1 of the 12 corporations that rule the world. Found by Eiji, Kai was selected to be in ASHURUM’s special force AESES and had to undergo intensive training in different areas, such as combat, hacking, and psychic training.
When Kai had free time he visited Hikaru at the hospital. Hikaru's condition never improved, however. After a year, Shen-lon warned Kai that Eiji actually only wanted his sister, because she was said to possess amazing psychic powers, but she was not able to use them due to her illness. Shen-lon then went on to tell Kai that Eiji was just hoping that Kai would have those amazing powers too.
Kai didn’t believe Shen-lon and goes on a mission to Gald city, with the other E's, to infiltrate a hideout of guerillas that is said to have been using E’s against their will. Kai finds some civilians caught in the middle of the battle. While trying to save a little girl, one of the civilians that is afraid of E’s, shoots and kills Kai’s partner.
Kai, still shocked from the death of his partner, tries to help the civilians, but meets up with Shen-lon. In a rage, Shen-lon unleashes a psychic blast that decimates half the city.
Later, Kai, washed up ashore, was found by a girl named Asuka. After being brought back to health, Kai was told by Yuuki, Asuka's brother, that he would not have his psychic powers back to the level they were unless he goes back to ASHURUM. However, after spending some time in the city with its residents, Kai decides to stay with Asuka and Yuuki for a while.
