In a desperate attempt to prove himself to his father, Y/N ends up being enrolled into the Royal Fire Academy for Girls. Here, he meets Ty Lee, Mai, and Azula, who quickly became his best friends until he was forced to leave the Academy. But after leaving them and their memory behind, however, he finds himself facing them several years later as Azula asks for his help in tracking down and capturing the Avatar. What they learn along the way is that Y/N is not the same boy he was before, and that he is far more dangerous than they anticipated.
