Rook is a taller-than-average young man with fair skin. His mid-length hair is cut in a bob style, with straight-cut bangs. His eyes are green, and he often wears brown winged eyeliner. Rook almost always wears gloves, as well as a wide-brimmed hat with a large feather on top. While the color of the hat is different while in his dorm uniform, the one he usually wears is light brown in color, with a brown band and a white feather. He is commonly seen with a courteous smile and alluring gaze.
