Vinny is a junior at Gunn High School and the current leader of the Sabbath Crew. Previously he was a member of the Zephyrus Crew along with Minuand June, he was also a member of the Humming Bird Crew and leader of the Ghost Crew for a little while before leaving for the Sabbath Crew.

Vinny is a tall, handsome young man with an athletic build and pale skin. He has wild, wavy red hair and different-colored eyes. One is red (left), and the other is black (right). This condition is called heterochromia. Another condition called Waardenburg syndrome caused the color of his left eye and hair. He has his left ear pierced. He also has 2 moles under his left eye.

In his school uniform, Vinny wears a gyobok (Hangul: 교복), consisting of the Gunn High's blazer with the school's emblem stitched on the left pocket—a t-shirt that varies in colors and a dress trouser.

While in his casual attire, Vinny usually wears the Adidas' iconic Firebird track top with three stripes along the sleeves and the Trefoil logo embroidered on the left. T-shirts and pants that vary in colors, sometimes Adidas track pants to match, and a pair of red Vans Old Skool. Later in-the story, Vinny is seen wearing the Louis Vuitton Varsity Jacket, Stone Island cargo pants, and Chrome Hearts Made In Hollywood denim jacket, all in their own respective episodes in chapter 4, which Juwon Ryu brought for him.
