When she is first introduced, Haruna is shown to have long slightly unkept black hair that extends down to her waist. She also had blank yet manic smile on her face which was likely caused by her exposure to Saika driving her insane. In her first appearance, she wore her school uniform which was similar in design of Raira's save for the much longer skirt and the yellow tie. Personality-wise, it is made very clear that Haruna was driven half-mad by Saika's influence and had deluded herself into believing she had control of Saika when in reality it was the other way around.
When she returns in volume 8, Haruna's appearance changes significantly. Instead of her school uniform, she wears a long pink dress and a pink headband. She also carries several small knives hidden under her skirt and uses a large red scythe instead of her old kitchen knife. Haruna also has several bandages wrapped around the spot on her neck where Anri cut her the first time they fought. While she still retains an unhealthy obsession with Nasujima, her mental state seems to be more stable than it was when she first appeared (although that isn't saying much, all things considered).
Under the influence of a daughter blade of Saika, Haruna fell in "love" with her teacher Takashi Nasujima. She was caught trying to injure Nasujima with Saika's daughter, and afterward had to transfer to another high school in West Ikebukuro.
BackgroundEditAt some point before the start of the series, Haruna entered into a romantic relationship with her teacher, Takashi Nasujima. While Nasujima was merely using haruna to extort money off of her, Haruna was genuinely in love and grew a obsessed with him. Eventually, Haruna came into contact with one of Saika's daughter blades and was eventually driven half mad by it's influence. This resulted in her attacking Nasujima which caused her to get transfered to a different school in west Ikebukuro. As Saika's influence grew stronger within her, Haruna eventually decided to spread Saika's "love" scross the city. She also realizes that Nasujima has started make advances towards Anri and, out of jelousy, decides to kill her as well.
Haruna starts the attacks of the slasher by cutting various people to "infect" others with Saika's spirit, calling them her children. Haruna also runs into Shizuo Heiwajima at some point during her cutting spree and, seeing him as a useful tool, Saika compels haruna to somehow bring Shizuo under her influence. A couple months into her plan, Haruna saves Anri from some bullies and ran off. Haruna is also seen spamming the chat room under the screen name of Saika. The others try to ignore her until she brings up Shizuo before abruptly cutting off communication.
Haruna decides to cut her father in order to use him as a scapegoat to attak Anri. When he fails to do so she decides to take care of Anri herself and pays a visit to her apartment. At the same time, Haruna also begins to launch a full scale invasion of the city and sends her children to attack Shizuo. Haruna talks to Anri about Takashi and explains how she wishes to take revenge on her for stealing him away.However, someone knocks on the door and Haruna goes to answer with the inent of cutting whoever was knocking. Much to her surpise, Nasujima was the one who was knocking which causes her to chase after him while she leaves her children to finsh off Anri.
She corners Takashi and rubs blood on his face in an attempt to show her "love when Anri comes in much to Haruna's surprise. Haruna asks Anri how'd she lived and Anri told her that she had the true Saika as well as how she obtained it, pulling out her Katana as proof. Haruna insists tah she has the true blade and attacks Anri several times. However, it is revealed that Anri is merely letting Haruna cut her as punishment for what she was about to do. She then cuts Haruna neck, taking control of Haruna as well as all her children.
At some point after her fight with Anri, Haruna manages to break free of Saika's control again and decides to take revenge on her.
She along with several others are called in by Izaya to work for him.
Dragon Zombie ArcEdit
she assissts in rescuing Izaya after he got kidnapped by taking control of several members of the group "Amphisbaena" that were holding him captive. Izaya compliments her for using Saika instead of simply suppressing it, but he narrowly avoids her attack. Haruna asks if Izaya will keep his word about leading her to both Anri and Takashi. Izaya reassures her and requests that Haruna take control of Earthworm (the leader of "Amphisbaena) so that they can use her.
Her father, Shuji Niekawa is a reporter working for a small-time magazine.
Kadota's Coma ArcEdit
There are several scenes of Niekawa Shuji looking for his runaway daughter, by approaching the police as well as the Awakusu, which eventually end in him meeting Ryuugamine Mikado and the Blue Squares. Niekawa Shuji says, apologetically, that when he looked through her computer to find clues as to where to find her, he found that she was involved in the Dollars.
Under Orihara Izaya, Haruna sends her "children" to attack Yodogiri Jinnai. The police officers in custody of Shizuo are her "children" as well. It is almost certain, although never stated, that Izaya had her cause Kadota's accident. Kadota is not seen conscious after the accident so it is unknown if he saw the culprit.
