Like the rest of the Shadows in the house, Patrick is completely black and appears to be a silhouette of his "face", Ricky. Patrick is a young boy with short, neatly kept hair and wears green Victorian style clothing with white frills and beige shorts.
Patrick is arrogant, confident and loyal. He has a strong sense of duty and will help out those who help him. He's not as smug as his "Face", Ricky but can definitely be annoying at times. He gets along well with the other Shadows and has taken a particular interest in Kate's "Face", Emilyko after she offered to help him in the debut. In later chapters, it was revealed that he, in fact, had fallen in love with Emilyko.
Patrick admires Ricky's strong personality. It's been shown throughout the manga that Ricky carries (not physically) Patrick throughout debut and social life as Patrick himself isn't a strong character.
Patrick is revealed to have developed a crush on Emilyko.
