ATID-635 Uncensored Karen Usami, a woman from the underworld

My job is a jack-of-all-trades in the underworld... I'm known as the Swallowtail Woman because of the tattoo on my foot. My current job is to expose the evil deeds of Oki, the boss of a human trafficking organization. I will obtain conclusive evidence and eliminate Oki from both the public and the underworld. I will also free the children who are being traded as commodities. Children who are in the same situation as I was in the past...
