S1, E1: The Lovely Angels' latest mission has them rushing off to Karosu Prison, a heavily armed fortress floating atop a blazing star. Seems the prisoners have all decided to riot, killing most of the guards in the process. The Marines are about to storm in and stop the uprising, but someone needs to retrieve the warden before he gets killed in the crossfire. That kind of mission takes a delicate touch, and Kei and Yuri are just the ladies for the job!
