Yamori's torturer was formerly an interrogator stationed at the CCG's Ghoul Detention Center. He is notorious for his sadistic tendencies, and is noted as the person who tortured the once imprisoned Yakumo Oomori.
After his mishap with Yamori's escape, he was later seen working at the CCG Academy. Whether he continues to work there now is currently unknown.
Yamori's torturer was once an interrogator working at the Ghoul Detention Center. During this period, he was assigned to interrogate a newly imprisoned ghoul by the name of Yakumo Oomori, who had a considerable amount knowledge relating to the 13th ward. Because of his barbarous mentality, Yamori's torturer used this occasion to inflicted excruciating torture on Yamori for an unspecified number of days. At some point, a moment came where Yamori was able to break free from captivity. Yamori grasped this short opportunity to subject the pain he received onto his torturer.
Some time later, after Yamori's escape from the Detention Center, Yamori's torturer began working at the CCG Academy. He continued his deranged habits by taking animals he acquired and slaughtering them. He would then leave the dead bodies scattered around outside the facility. He killed up to 10 dogs, 40 cats, and number of other smaller animals. One night, Juuzou Suzuya had stumbled upon him outdoors after recently killing a cat. He then threatened to kill Suzuya if he ever informed anyone of what he saw. At some point, Yamori's torturer was exposed to other staff members. Because he was employed with the CCG, the rest of the staff devised a plan to use Suzuya as a scapegoat to cover for his actions, in order to circumvent a potential scandal.
- The habit and the way of cracking the finger he had was passed, unintentionally, from him to Yamori who also unintentionally passed it to Kaneki and Naki.
