Patrick is one of the side protagonists in the Shadows House series and the Shadow living under the care of the "Living Doll", Ricky. 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 be annoying at times.

Spoiler

During the debut, he has a panic attack, showing that he actually has many insecurities caused by a desire to prove himself and show that he is of worth. After the debut, he retains much of the same personality but has become kinder and far more humble, and open-minded. He gets along well with the other Shadows and has taken a particular interest in Kate's "Face", Emilico after she comforted him during the debut. In later chapters, it is revealed that he, in fact, had fallen in love with Emilico.
