Kureo Mado

Mado was known for his obsession for ghouls and their kagunes for the purpose of making quinques. He frequently waited for the ghoul he hunted to bring out their kagune in order to obtain it, according to how all investigators do when looking forward to a new quinque. His uncommon enthusiasm toward ghoul hunting stemmed from when his wife, Kasuka, was ordered to hold off the One-Eyed Owl alone and died about ten years previously during an investigation in the 24th ward. This tragic event left him and his daughter, Akira, devastated. He gave in to the overwhelming desire for revenge, which made his obsession for ghouls akin to a coping mechanism, that shaped who he is at the present. As an investigator, years of veteran-ship and expertise had given him a deep insight and intuition to sense a slight detail to determine someone's status as a ghoul. His deductions had led Amon to admire and learn from him as mentor to mentee. While Kureo was violent and cruel towards ghouls, to his fellow humans and brethren-in-arms he was just an ordinary old man with good work ethics, though considered weird by many people. He was capable of loving and caring, as indicated that he was married and acted as a very dedicated teacher to his juniors. Ten years ago, he used to be partners with Yukinori Shinohara and Fujishige Iba during the Owl case. Mado seemed eccentric and senile from outward appearance, but he was one of the best investigators around as an expert in combat and a pioneer in quinque engineering. According to Akira, he never wanted nor attempted to achieve a higher rank than First Class Investigator, saying it was all he needed to go after the Owl and looked down on those who blindly chased ranks within the CCG. However, the grief from his wife's death created a turmoil of rage targeted at all ghouls, and this made him rather sadistic towards ghouls. This was showcased when he laughed at and tormented Hinami about the deaths of her parents and told her she would join them soon enough, even though she was only a child who had emotions just like humans. Along with this, he belittled Hinami's mother and despite her desperate pleas, took immense pleasure in watching her death. This showed his extremely violent, almost psychopathic nature towards all ghouls and his inability for empathy and understanding for others in that sense.

Kureo was a middle-aged man with sunken cheeks that reminded Amon of a dead person. He had long, stringy, white hair and was often seen with a huge grin on his face. He had a slim body and stooped shoulders, causing him to appear considerably shorter. He was often seen with one bulging eye, and one squinting eye. He wore a white dress shirt and light dress pants, and black dress shoes. He wore a dark red necktie and a grey trench coat, adorned with shiny, silver accents. He was characteristically seen wearing white gloves. He was rarely seen without his briefcase. In his younger days, Kureo's expression was normal, and his hair was shorter.

Known as the "Quinque Fanatic," Mado collected and used many different quinques during his career and was an experienced fighter. In Tokyo Ghoul, he was seen wielding two different quinques: * Unnamed Quinque: The first quinque Mado was seen using in the anime. It is believed to be a bikaku-type quinque. It was destroyed by Yakumo Oomori. * Fueguchi One: This is a rinkaku quinque that was created from Asaki Fueguchi's kagune. It looks like a spine that was tied together. It is a high speed combat quinque with a sharp cut. It was later given to Akira Mado. * Fueguchi Two: This is a koukaku quinque that was created from Ryouko Fueguchi's kagune. It has the appearance of flower petals that spread in four directions. It can defend against attacks of any kagune and counterattack with a thrust. This quinque combines both offense and defense.
