Returning from the mysterious world, witch Harry only wants a peaceful life and to experience Hogwarts, this fairytale playground, firsthand. However, a certain self-proclaimed Dark Lord and some so-called "important figures" seem determined to prevent her from having her way. So, it's time to let the wizarding world know what true "calamity" really is. (Those who haven't read Harry Potter or Lord of Mysteries won't be affected.)
