Tazuna is a young boy who loves to fix things. But his life takes an unexpected turn when he meets a girl who's lying on a hospital bed in an electronically locked lab. When he takes her hand, he finds out that he can never let go, or she will die. On top of that, he has to battle a man and his partner in something called the Ziggurat, and he doesn't have a power of his own. Can he unlock the might of the Hand Shakers?

Kurusu has tracked down the identity of the killer, and revealed her secret to Takuru. Now she goes to the school to meet with the one behind all the murders.

After Yui's death, Takuru's family tries its best to recover. Kurusu makes a shocking admission to Takuru that she's been hiding something from him ever since he met her. She's willing to do anything to find the killer, and she's getting very, very close...

Senri Minamisawa is dead. She became the fifth victim of the New Generation Madness, commiting suicide by impaling herself on a piece of rebar and then setting herself on fire in her own locked apartment. Takuru and his friends are relieved, but at the same time uncertain that it's really over. Just in case, they decide to stay together on the day of the next murder. Everyone hides out at Aoba Clinic, where it should be safe, but then Yui and Itou go missing...

It's October 23rd, the day of the New Generation Madness incident, and it's time for the next murder. Takuru and his friends are terrified that they're going to be a target, and so they stay up all night at Cafe LAX. But when Takuru opens the cafe menu once last time in the late hours of the evening, he finds a Sumo Sticker stuck to one of the pages...

Takuru and the others find a survivor in the basement of the hospital. Her name is Uki Yamazoe, and she's a young girl who looks to be around 10 years old. After seeing how Takuru was able to infiltrate the hospital, Kunosato realizes that he must be a "Gigalomaniac", a psychic with the power to make his delusions reality. But being a psychic doesn't come with just benefits, as one night he runs into someone who is trying to kill him...

After Kurusu is stabbed, Takuru infiltrates AH Tokyo General Hospital, hoping to find the creator of the sumo stickers. When he gets there, he, Onoe, and Itou are forced to hide in the basement to avoid being spotted. Inside the basement's autopsy room, they find a secret entrance that leads to an underground laboratory where terrible experiments were once conducted. Takuru thinks he's been here before...

After Kurusu is stabbed, the newspaper club is placed on hiatus. But Watabe, an important reporter with Niconiya News, wants to interview them about the things they've noticed with the sumo stickers and the hotel murder. Watabe's visit to the school, however, takes an unexpected and terrifying turn...

After Takuru is taken in by the police, Kurusu wants him to give up the case. But he's noticed something... the sumo stickers that have been placed all around town have something in common with the murder scenes. He puts up a hidden camera near a wall of sumo stickers that just appeared. But when Kurusu finds out, she leaves in the middle of the night to take it down...

The final battle takes place in the Hikariwo theater, where Takuru is trapped in a sightless and soundless prison in his own mind. He'll need Onoe's help to break free, but after what he knows about her, can he bring himself to ask for it?

"Let's meet at the place where it all began." The true plot is revealed as Takuru travels to the Hikariwo. There he eets the other person behind the series of brutal killings. But a deeper mystery lurks in the background: what Serika is telling him doesn't make sense, and he's convinced that as horrible as the story is, there's more to it than even he knows.

Takuru is forced to confront his own involvement in the case, and the secrets of his past. He was a neglected and abused child, who turned to an imaginary friend for support. This decision has terrible consequences during the Shibuya Earthquake.

Years after an Earthquake destroyed much of downtown Shibuya, the city is rocked by a series of brutal murders. A man eats his own hand. A woman rips open her own stomach and stuffs a speaker inside. Takuru Miyashiro, a student at Hekiho Academy, is investigating these murders as part of the school's newspaper club. But when he finds a break in the case, it turns out to be closer to him than he ever thought...

A new Neuroi has appeared and is threatening the supply lines that the 502nd worked so hard to establish. With the upcoming strike on the Neuroi nest, this threat cannot be allowed to stand. But Krupinski injured after the last battle, and the other senior Witches disabled, it falls to Kanno to lead the charge in her first real command experience.

The Witches are preparing for a large-scale attack on the Neuroi nest, and to do that they'll need a new weapon. This new weapon is being transported via a supposedly safe route. Krupinski is given the task of defending the convoy. Some of the younger members are a little worried about the always-joking Krupinski, but when a powerful Neuroi attacks, she gets the opportunity to show them what she can do!

It's time for the Saturnus festival, and there's no food to celebrate with! What's worse, Hikari has come down with a cold from all the stress she's under. Nipa and Kanno decide to put on a Christmas celebration anyway, using local mushrooms and hand-carved presents, but their plans are interrupted by a surprise Neuroi attack. Can a surprise visit from Grandpa Winter save the day?

The base is under attack by an artillery Neuroi! It's striking from a long distance away, and it's being guided by a marker Neuroi inside the town. Sasha leads the team to take out the marker Neuroi inside Petersburg. She's convinced she's never been here before, but she still remembers this place. Since her magical power gives her a perfect memory, how could she have forgotten?

Shimohara, Georgette and Hikari are out on patrol when they find the whole lake near the base has frozen over! It's an ice Neuroi! They engage the enemy, but it's too cold, and freezes their units solid. The Neuroi then proceeds to freeze the entire base! With no one else able to launch, it's up to the three of them to take out this frozen foe.

The battle against the Neuroi is a difficult one, and the 502nd is worried that Hikaru doesn't have what it takes. She's issued a challenge: if she wants to remain in the unit, she must use her magic to climb up a tall tower and grab a hat off the top. She's not allowed to fly, and worse, she's only given seven days to do it. As the day of the deadline draws near, she still isn't making progress, but she refuses to give up.

Hikari is now a full member of the 502nd, but she's not exactly welcome yet. Compared to the rest of the members, she's woefully underpowered, and the trainer isn't sure she should be allowed to fight with them at all. When one of the girls go missing after returning from a flight, though, she has to go out and find them, and help defend against a Neuroi when it attacks.
