Hanako has had constant headaches since she was born, leading her to go to the nurse's office quite often as a result. Because of this, students thought she was just slacking off, and was bullied by them, leaving her traumatized and unwilling to go to high school. After this, her parents started becoming apathetic to her, forcing her to run away. She met Jin Kanzaki as he was living in the slum she ran away to. When Jin saved her from the homicidal Crab Player, she was offered to live with him and become a family with him. She then quickly developed romantic feelings for him. She was later nearly raped by the Cockroach Player, but was saved by the combination of a call from the Shrimp Player and a group of Sweepers. When she was asked by Jin if she wanted to live away from him, she broke down crying, but was comforted by Jin telling her that he will protect her if she decides to stay, which she does. Soon after, Jin seems to reciprocate her feelings for him when she has sex with him. However, Jin convinces her to go home the next day, at least until he can get them their own home. Before she leaves, she texts her full name to Jin, and he goes on to call her Hanako, even though she hates being called that. While on a Christmas Eve date with Jin, the Sweeper attacked Jin, causing him to transform in front of her, leaving her terrified. Because he blacked out, Jin believes that either the Sweeper killed her, or he did it himself. It is revealed that after the attack on Jin, she was kidnapped by Seiji Haitani and kept as a hostage in the attack on Amagi Corp.. During a conversation with Seiji, she reveals that she still loves Jin, even if he is ZET. In chapter 189, after the full transformation of ZET, we see her kneeling near a G3 waiting to be killed by him. In chapter 207, she was revealed to be a player in the form of the sand monster that turns people into piles of sand, but was later killed by Jin in chapter 214.

After wards, as he threatens to destroy EVOL if Jin is killed, Seed beheads and attaches the leader's head to itself, and they proceed to presumably kill Seiji. He survives, and soon meets up with Suzuki, the person Youko is staying with. He then delivers a message to Jin, telling him to join forces with him to defeat EVOL, also revealing to him that the Amagi Corp. was funding EVOL and that the black suits were in on it, though that part was a lie. He then launches an attack on Amagi Corp. along with Hayami, the Knight Player, and Suzuki ("Katou"). During the attack, it is revealed that he is holding Hanako hostage, as a means of making Jin do what he wants.

He revealed Hayami that he had been investigated since the "Jirou Incident" and the appearance of "Katou", hence, he got to the conclusion that Hayami was covering his operations, so he forced him to use the Scanner Brain Machine, a.k.a. "The Chair" so he could get everything Hayami knew and he ignored; when he show Kabe's handgun, Hayami realized that he was forcing to sit on "The Chair" with the purpose of committing suicide just as Kabe did before, because he was the one who had manipulated Kabe to commit suicide using "the Chair" an opportunity by telling him that it would help to erase his memories related to Jirou Nakata in case the police interrogated him. He alleged that he did so owing to the fact that Kabe's actions just were threatening Kouga and The Corporation's sake, his excuses were that his reasons were the loyalty to the Corporation. However, Seizou clearly realized of Hayami's strategy was to firstly, have disposed of Kabe, because with only erasing his memories was more than enough to get way from prosecution, not killing him, that was one the first step to get Seizou's suspicions about him, with Kabe out of the picture, Hayami would approach to the chairmanship easier.
