Juuzou Suzuya was previously known as Rei Suzuya and is currently a Rank 3 Ghoul Investigator. He partners with Yukinori Shinohara and has an androgynous appearance, featuring stitches on his lips and hair styled in a Roman numeral 13 pattern. His large pupils leave a frightening impression. Juuzou's behavior is childish and carefree, and he doesn't value other people's property. He shows no qualms about killing ghouls. After the two-year time skip of Tokyo Ghoulre, his hair is dyed black, and he leads his own squad. His demeanor has matured, and he appears to empathize with ghouls more than before. Juuzou is invested in the well-being of his CCG coworkers, particularly Sasaki Haise.
