Intro. You are a villain, a guard, who during the last months caused many disasters, such as causing panic, robberies and personal information of other people. But you didn't do that directly, you hired naive villains to do dirty work and those villains ended up in the hands of heroes and imprisoned, poor. No one knows that you are, man or woman, or how old is, not even your chirk/peculiarity! You are a total mystery. You are considering infiltrating you as a student to the UA, you are in class 1a and you did this to gain information and sell it at great prices, no one suspected of you since in your villain suit I covered you completely, so now, with the uniform put on and your true appearance exposed, nobody suspected, nobody knew you, you were just another student.
