Kichimura Washuu

Nimura Furuta (旧多 二福, Furuta Nimura) is a Rank 1 Investigator and the former partner of Shiki Kijima.

Appearance
Furuta has dark, medium-length turquoise hair that is parted on his left. He wears a black overcoat on top of his suit with a bow tie, like Kijima does. He occasionally wears a trench coat like the other investigators do.

Personality
Furuta is a seemingly normal investigator who complains about his boss. It is however revealed that he has a dark side when he casually uses a fellow investigator as a human shield. He doesn't hold any respect for fellow investigators, and seems to be acquainted with Mr. MM, despite being a CCG investigator. Very shady

Prelude to Anteiku Raid
When Touka Kirishima was visiting Kamii University, she mistook Furuta for Ken Kaneki.

Rosewald Investigation
Furuta acted as a drunk businessman loitering around possible Rose hunting grounds, complaining about his superior. He then successfully lured a Rose hunting group to attack him, falling into the CCG's ambush.

Tsukiyama Family Extermination Operation
He later joins in the assault on Lunar Eclipse, and was seen on standby when Kijima and Hairu fought Matsumae and other Tsukiyama servants. When Kijima's quinque dug into its owner's head, Furuta looked at the scene with horror. He then contacts Ui to inquire about when the reinforcement will arrive, and proceeds to use a fellow investigator as a human shield against Matsumae. When asked what he was doing, Furuta calmly replies "standing back behind him" and proceeds to destroy Matsumae's eyes barehanded before stepping over Kijima's body to kill Matsumae with Kijima's quinque, saying "I'm sorry, Mr. MM."

Some time later, Koori Ui and his squad arrive to discover a scene of carnage. Furuta is discovered collapsed against a pillar appearing to be badly beaten, as the only survivor of the battle. He reports that two of Tsukiyama's bodyguards managed to kill everyone, but a flashback reveals that he tore Matsumae's kagune free and used it to kill the other surviving Investigator to cover his tracks. While a vehicle is called to transport the bodies, he appears to break down in tears over the death of his partner, but it is revealed to actually be laughing.

After the battle is over and the CCG transports the bodies of the killed investigators, several members of Aogiri Tree attacked the transport vehicles and stole Shirazu's corpse. Furuta watches the scene, holding his smartphone in his hands, while smiling and singing Donna Donna. It is implied that he is the perpetrator who revealed the transport routes to Aogiri.

Post-Tsukiyama Operation
After the six months timeskip, he is briefly seen with Ken Kaneki, paying a visit to Takatsuki Sen's manager and requesting a meet with Takatsuki Sen with the said investigator.

Shiki Kijima
Kijima was Furuta's current superior partner. While he was acting drunk, he mentioned that he was annoyed by his boss. He seemed to care for his superior, but this ultimately proved to be false after Kijima's death. Furuta shows an utter lack of regard for his superior, even going so far as to step on his body.

Shuu Tsukiyama
It can be assumed that Furuta is associated with Tsukiyama under another persona, as he is aware of Tsukiyama's restaurant name, "Mr. MM."

Powers and Abilities
He presumably has some experience and talent in battling ghouls. In particular, he demonstrates both impressive speed and strength when battling Matsumae -- stabbing out her eyes with his bare hands, and easily dodging her attacks. His abilities are testified when he manages to kill Matsumae, who killed Ihei and Kijima. Afterwards, he performs another incredible feat of strength by tearing Matsumae's Koukaku free from her body with his bare hands and uses it to kill another Investigator. The resulting damage suggested an attacker of incredible strength, fooling experienced Investigators into believing it was done by a Ghoul.
