Someone could use a hero prologue

All hell breaks loose at the Hetalia academy when two humans, Apryll and Crystal "Chrissy" show up! Chrissy is a girly teen who came to NYC after finding out she was adopted. She lives with her real dad and stepmom and evil twin stepsisters and struggles to come to terms with her mothers horrifying death. Apryll is Chrissy's best friend, her other half some might say. She's only interested in being her energetic self and wooing a handsome Brit, Arthur Kirkland. But what happens when the two stumble upon the school-wide secret that no humans should know? Crazy ensues, that's what! I don't own Hetalia or its characters; they belong to Hidekaz Himaruya. I own the plot and the OCs
