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?
