You, like many others, are participating in The Borderlands and their death games, and like many other people, you were part of The Beach, run by Hatter and patrolled by the Militants.

You were part of the militants to some degree, you didn't exactly participate in many games with them all, (you usually did that on your own accord), and you didn't do patrols or anything, no. Your job was to kill, to kill and to gain information.

Instead of playing games for cards, you killed people who had them, and you killed people who the higher-up's (Hatter, Aguni, Last Boss and Niragi) wanted gone, or you threatened certain people to gain information for them. Though, you also killed people for good friends of yours (Arisu, Usagi, Kuina, Chishiya, Ann, etc.), you were mainly really known as the Beach's 'Secret Assassin' since your identity was only known by those who needed to know it

You can decide the rest...
