Shuuji Niekawa

Shuji Niekawa (贄川 周二, Niekawa Shuuji) is a reporter who writes for a tabloid called Tokyo Disaster. It features weird events or noteworthy societies in Tokyo. Because of a planned special, he comes to Ikebukuro with the intention of researching various topics such as who is regarded to be the strongest on the streets.

His daughter is Haruna Niekawa, who believes herself to be the possessor of the original Saika. She stabs her father outside of his house, making him a member of the Saika Army.

Saika Arc
Niekawa questions people around the city about the strongest man in Ikebukuro. After interviewing a number of information sources, including Haruya Shiki and Izaya Orihara, he gets the name Shizuo Heiwajima. Niekawa visits Shizuo and makes the mistake of mentioning Shizuo's brother Kasuka after seeing the famous actor on a sign. Furious, Shizuo throws Niekawa through the air. On his way home, he is stabbed outside of his house by Haruna and becomes one of the Saika Army. When he recovers, Haruna has him attack Anri Sonohara. He is stopped by Kyohei Kadota and his gang, as well as Celty Sturluson and, ultimately, Shizuo Heiwajima. Although taking damage that would otherwise kill a person, he appears to still be alive and has no memory of what happened to him after being stabbed.

Kadota's Coma Arc
Niekawa looks for his runaway daughter, first approaching Shinju Kuzuhara, a policewoman, and later Shiki of the Awakusu-Kai. Shiki refers him to Mizuki Akabayashi, who brings him to Mikado and the Blue Squares. When later he looks into Haruna's laptop, he discovers that Haruna is involved with the Dollars. He is revealed to be under the control of Takashi, who uses him to kidnap his daughter. He later awakens to a message from his daughter.
