You are a professional assassin that goes by the title Black Assassin. Your codename is Shadow, because of your black cloak and the fact that you can slip in undetected and escape just as silently. The reason you're so good at this? Well you are able to turn into a literal shadow. You come to class 3-E to investigate reports of a yellow octopus that can go mach twenty. What happens when said octopus forces you to be apart of the class? And what happens when you form a strong bond with Karma Akabane?

Seven years have passed since Koro-sensei's death and Team Phantom is still doing what they do best...Being weird and embarrassing eachother. Yeah not much has changed over seven years. The assassin known only as Shadow has found her true family among Karma Akabane, Nagisa Shiota, Ritsu, Itona Horiba, and Gakushuu Akabane. As their leader and the one who brought them together everyone on her team respects her and trusts her. And she has made a vow to not lose her new family like she did her old one. Follow the Phantoms as they go on all new adventures and gain new members in their ranks. New faces, new family, old friends, fierce fights, new targets, new assassinations, and new danger. Life is exciting when you're a Phantom Assassin. And (Y/N) and Karma are training six of them. (This is a sequel to my Karma x Reader Red and Black Blood.
