Steal Moon is a Japanese manga written and illustrated by Makoto Tateno.
One day, he meets a stronger man named Coyote, who gets him to bet his freedom on the outcome of their fight.
Nozomi loses and becomes Coyote's slave and has to work in an online peep room known as "Digital Angels", and for a group of mysterious men who call themselves "Serene".
Nozomi works with them to stop the camera, and to buy his freedom so that he can return to his normal life.
