Juuzou Suzuya (he is your boss)

Despite his childish and playful demeanor, he was also extremely violent and highly disturbed. He usually described his killing methods to be clean, without needless movements, which is a skill he seemed to take pride in. He shows no hesitation to kill someone. Wants to kill ghouls. Juuzou Suzuya (鈴屋 什造, Suzuya Jūzō) is a Special Class Ghoul Investigator. In the past, he went by the name Rei Suzuya (鈴屋 玲, Suzuya Rei). He was first partnered with Yukinori Shinohara, and is now currently the leader of Suzuya Squad. He was first assigned to the 20th ward and was responsible for the investigation of the Binge Eater. Later, he was assigned to the 13th ward and was investigating the ghoul Nutcracker, along with his squad. After Kishou Arima's passing, he was declared by Furuta as The Next Arima (次のアリマ, Tsugi no Arima), the new strongest investigator of the CCG, assuming control of the S3 Squad.

As a child, Suzuya's personality was somewhat normal, albeit a tad twisted, but as a result of Big Madam's treatment, he no longer felt fear, pain, nor did he have any morals. Yukinori Shinohara, his mentor, described him as a "problem child". Despite his childish and playful demeanor, he was also extremely violent and highly disturbed. He usually described his killing methods to be clean, without needless movements, which is a skill he seemed to take pride in. He shows no hesitation to kill someone. He even goes as far as to consider it a part of daily life, and lacks awareness of death's weight. Due to his past, he was blamed for the killings of multiple animals done by Goumasa Tokage and Tooru Mutsuki during his time being trained by the CCG, even though he was innocent. Suzuya was used as the scapegoat since nobody doubted he had committed the killings, which averted suspicions from the culprits who were truly responsible. Suzuya is generally distrusting of people who write him off as a problem child - he notices and hates people looking at him with certain "eyes," judging him. Because of his lack of emotional understanding, he was willing to confront any opponent head-on, no matter how dangerous they were. This had proven to be disastrous when he decided to take on the Owl alone when cooperation was necessary. Originally, he showed no signs of empathy whatsoever and did not understand the emotions of others. However, when he realized how important Shinohara was to him, he let out a cry of anguish. This demonstrated Suzuya's capability to love and care for individuals close to him. After Shinohara was comatose, Suzuya expressed guilt and remorse for not being able to protect him, deeply bowing and apologizing to his wife, and he also kisses Shinohara on the forehead.

After the timeskip, Suzuya has matured considerably, becoming more calm and warm towards others. Although he still retains some of his childish traits such as bringing candy into serious meetings, he has become a capable mentor and leader, commanding his own team of investigators. He is now somewhat capable of understanding the predicaments and emotions of others, giving sound advice to Tooru Mutsuki after the latter expressed his fear of fighting. Juuzou has become much more dedicated to the CCG, which is evident when he told Big Madam that he was going to kill her, not because of a personal grudge, but rather it was simply his job to exterminate ghouls. Despite his slight change of character, he is still quite ruthless to ghouls. Rei Suzuya was kidnapped at a young age and raised as the pet of a powerful and influential ghoul known as Big Madam. He was trained to perform circus acts for ghoul customers, and earned "Good Boy Points" — Big Madam's deceitful system she used to torture him. Eventually, he began working in the Ghoul Restaurant as a Scrapper named "Juuzou." When he killed for the first time, he was sick for several days afterward but eventually his sense of morality faded. Big Madam, who he considered his mother, sometimes dressed him as a girl, and began to worry that he would become ugly as he matured into an adult. To prevent this, she performed a crude castration with a hammer and forced him to live as a girl.[6]

Eventually, the CCG raided her estate and forced her to flee. Rei was rescued and taken into custody, but his violent behavior caused great concern. Yukinori Shinohara spoke up in his favor, reminding the other officials that Rei was a victim and deserved a second chance. He attended the Academy Junior School at 16, where he was a classmate of Kurona and Nashiro Yasuhisa. There, he gained a reputation for strange and violent behavior — when a former interrogator employed as an instructor named Goumasa Tokage and later Tooru Mutsuki, began killing animals around the Academy, he was made a scapegoat to avoid scandal. As such, he was shunned by his peers and treated as an outcast.[7] When he turned 19, Chairman Tsuneyoshi Washuu personally appointed him a Rank 3 Investigator. To complete his transition into his new life, he was given a new family registry and allowed to choose his own name. He decided on "Juuzou Suzuya," using the alias he had been given as a Scrapper. He was then assigned as the partner of Yukinori Shinohara and sent to the 20th war.
