My Assassin Academia

How would the villains and heroes react to an assassin as a Heroine who's code name was 《♧♤》 and has the same hot iron 'tattoo' of 《☆◇》as two other boys who are her male cousins on her right shoulder? How will she feel about her class, 1-B and a student of a teacher knowing about this very secret of her's and her old classroom's?

Not only that... Will she be able to tell them that her last classroom was one of ACTUAL blood shed, murder and assassination making them to not be normal anymore and her four Quirks making her to be called a 'Monster' and that she has somehow murdered her boyfriend's own father, the principal of her old school?
