Armored Knight Iris 1

Based on the Black Lilith video game, People began to go to space, and the federal space program, which was controlled by a variety of species, including humans, was in charge of maintaining public order and security. The main character, Iris, and her companion, Mei Ling, are ace pilots in the 101 special unit of the federal army's Special Support Forces (SSF). One of the conflicts results in Iris being abducted and carried to the whorehouse on Mirion, which is controlled by the opposing troops. She is compelled to wear a devil's collar around her neck, which explodes if she tries to flee.
