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.)

[I, Cassandra Malfoy.] [I am the most outstanding Slytherin, with clear ambitions!] [I am the brightest morning star of the pure-blood family, the eternal pride of Hogwarts!] [Voldemort will fall at my feet, the Ministry of Magic will bow before me, and the entire wizarding world will obey my leadership.] [To recast the glory of magic and to be supreme over all living beings, this is my ultimate goal!] "Wait, who are you? What are you talking about?" With golden curly hair and emerald eyes, the 11-year-old Cassandra listened.
