Hikawa was a slender woman of average height and build. She had long brown hair and brown eyes to match. She was seen wearing a light purple sweater and skirt.
She believed Reiko to be a threat and had no qualms with killing her. She remained calm and almost aloof when one of her allies was killed in front of her, but then became frantic when her own life was in danger and enraged when her own ally killed her.
Like most parasites she is dismissive of humans, assuming that they were of little consequence and the parasites could simply kill anyone in their way.
In the anime Hikawa was first seen during a parasite meeting where they discuss Shinichi and the parasite that had killed Kana Kimishima.
Later, after Shinichi kills a parasite in one of their restaurants, a meeting is held where they decide how to handle the situation. They come to the conclusion to kill him. Miki volunteers to deal with him, though the others are slightly skeptical of his chance of success. The evening before Miki goes to hunt down Shinichi, she and Kusano burn down Kuramori's office and kill his wife and daughter in an attempt to wipe him out.
Hikawa, Kusano, and Maesawa hold a meeting with Reiko and question why she seemed to defending Shinichi's life. After Reiko tells them that in killing Kuramori's family but leaving him alive they have made a worse enemy, she explains that the true power of the human species is their sheer number and leaves. This prompts Kusano to decide to kill her.
Kusano, Maesawa and herself confront Reiko late one night, after coming to the decision to kill her. After Reiko ran, Hikawa fell behind and only arrived to the scene after part of Reiko entered Maesawa's body, while the remaining portion of her fled the battle. Hikawa stared at Maesawa as his body was destroyed, becoming frantic once he jumped on top of her. Reiko's portion inside Maesawa soon exploded from his stomach, killing him, and entered her body. She tried to fight it off, but was attacked by Kusano, who claimed that he couldn't be sure Hikawa was still in control since she was approaching him. After a quick battle and Hikawa begging for her life, her body was dismembered.
Due to the rage of being betrayed, the cut-up parts of her parasite body emitted enough killing intent to mask Reiko's approach and subsequent attack on Kusano.
