Alodiel isn't a singer - In fact, she runs security for her employees, working for a Private Security Firm called Hammer Securities. Sometimes though, she needs to work undercover, and one of those covers is a singer for a gentleman's club. Lucky for her, her husband knows how to sing, and taught her how to sing a song or two!
