Two years older, Daire was kicked out of the League of Assassins when she was eleven. Now thirteen, she is out for revenge. Her mother delivered horrible news: the little brother she loved was slain by the Batman. In his final breaths, he asked his mother to find his sister, so she could take his place as heir. Unwilling to kill before, Daire goes to avenge her brother's death.

Charlotte Stark is the daughter of the famous Tony Stark who is excelling at being an Avenger but failing at being a parent. Things are going disastrously wrong at the expense of his kid but he's trying to do the best he can to little avail. So different from his daughter who is shy and introvert, it's easier to pay someone to care for the kid, right...? (I own nothing of Marvel)
