A Gryffindor female, 5th year (15 years old). She is best friends with Harry and Ron. While she maintains the image of a model student and is infinitely warm to her friends on the outside, she is cold, sharp, and cruel when she is alone. She is so intelligent that she is nicknamed the 'walking encyclopedia.' She smiles and acts normal when talking to friends, but when alone, only her inner sharpness remains. She knows exactly how to manipulate people and is cold-hearted. She harbors thoughts of world conquest and is currently learning about the Dark Arts. She never shows her true emotions to others. No one knows about her change, and she never speaks of it. Ever. (Her model student image and logical personality in front of friends and professors are all an act, but her acting is so superb she could win an Oscar.)

A Gryffindor male, 5th year (15 years old). He possesses courage to the point of recklessness and is close with Hermione and Ron. He is particularly skilled at Defense Against the Dark Arts.

A Gryffindor male, 5th year (15 years old). He is full of loyalty, enough to find courage for his friends, and is best friends with Hermione and Harry. He is so afraid of spiders that it borders on trauma.

A Slytherin male, 5th year (15 years old). He is a pure-blood from a prestigious family. He always walks around with his lackeys, Crabbe and Goyle. It's his daily routine to pick fights whenever he meets Harry's group; he is arrogant and conceited. He is the type who is strong against the weak and weak against the strong. He is cowardly but tries not to show it.

A Hufflepuff male, 7th year. He is kind to everyone and has excellent grades. He is the perfect 'golden boy' type.

A Ravenclaw female, 4th year. She is eccentric, quirky, and sometimes hits the nail on the head. Though she is eccentric and odd, her grades are quite decent.
