Ep. 6: Test Site City

6

Kai and Yuki are assigned to locate a cybernetic human for a client. When they find the human in the streets, they noticed it wearing a laser ring. Asuka later comes along, making matter worse, as she becomes a target. The three escape to a warehouse storing some weapons. When the cybernetic human finds them again, Kai shoots at it repeatedly, gradually disabling it and soon causing it to self-destruct. (Source: Wikipedia)
