Juuzou Suzuya (in Japanese: 鈴屋 什造, Suzuya Jūzō) is a Special Class Ghoul Investigator of the C.C.G. of the supernatural manga/anime series Tokyo Ghoul. He once went by the name of Rei Suzuya (鈴屋 玲, Suzuya Rei) in the past but changed it overtime. He's now a member of the CCG and has become a rather infamous member of the organization.
Juuzou was once a normal child in his youth but it changed overtime. Due to the treatment he had by Big Madam, Juuzou's understanding of emotions and morals were gone and he no longer feels any pain or fear as a result. He lacks moral understanding of what's right or wrong and due to him being blamed for killing animals by a psychotic Ghoul Investigator despite no evidence, he has been treated as an outcast and has little social interactions because of it. While Juuzou does demonstrate a very childish and playful manner whenever he is back at the main office, it is usually because of his mixed personality where he may seem nice but he holds very violent and destructive tendencies where he will lash out at any opponent and will kill them in brutal and inhumane ways.
Because of his lack of morality or basic understanding in general, Juuzou is willing to take on any opponent no matter how dangerous and powerful they may be and face them head on without second thoughts. However, this has proven to be absolutely disastrous, as he took on Yoshimura alone even though multiple people were needed to take him down. Originally he showed no signs of empathy and understanding of others but, he had cared for Shinohara and cried out when Eto stabbed him during the 20th Ward Raid. Following the events of the Anteiku Raid, Juuzou appears to have matured and is more calm and not be a nihilist anymore due the fact of his mentor condition and teaching, also he cares for the lives of his underlings and never abandons them. He still maintains violent tendencies and still lashes out at ghouls violently when in combat but is more peaceful when he is not fighting.
In the Japanese version, he was voiced by Rie Kugimiya. In the English version, he was voiced by the famous voice actress, Maxey Whitehead.
