The Robot Research Club's newest giant robot, GunBuild-2, is finally complete! Meanwhile, both Exoskeleton Co. and Mizuka catch wind of Kaito's activities surrounding Kou Kimijima.
Mizuka's steel legs
A flashback shows a wreckage and an injured Mizuka laying in the midst. Sometime later, as Mizuka struggles to close her shop while in a wheel chair, she receives a pair of mechanical legs from Misaki.
At one of the Tanegashima Space Center's warehouses, Akiho congratulates her teams as she unveils the completed Gunbuild-2. Akiho calls for a test of the robot, but Junna reminds her that they have to wait until a staff member from the space center arrives to supervise their procedures. In the meantime, Subaru assigns everyone a job in controlling the robot. Then Subaru describes how the robot works and mentions that the robot is unique because it runs on the power of the monopole that have been falling from the sky more frequently. As the GunBuild-2 takes its first steps in the test, the club is amazed by how it looks like Gunvarrel. It is at this moment that Nae arrives and congratulates them on a job well done. Unfortunately, she is also there to tell them that they cannot use the facility anymore since the space center is preparing to launch a rocket in the near future.
The packs up the robot and transfer it to the hanger using trucks. As Kaito watches a video of the president of Exoskeleton giving a speech to a crowd of reporters Subaru shows him a video that Akiho plans to send to the Expo. Subaru mentions how he is amazed that Akiho has not wavered from reaching her dream despite Gunvarrel's increasing unpopularity and people's distrust in robots. Later, Kaito asks Genji where the possible locations for the 7th report could be. As soon as Genji says rocket, memories of Misaki start flowing through Kaito.
Misaki's loyalty is questioned
At the headquarters of Exoskeleton, Toshiyuki Sawada links a twipo that Junna had sent to Kaito. He believes that Kaito knows too much about Kimijima and scolds Misaki for not preventing him accessing the information. He then questions whether Misaki is protecting Kaito, Misaki assures him that she will be willing to dispose of Kaito if she had to.
At the hanger, Mitsuhiko e-mails the club that he will be late and the club decides to go ahead with the test without his supervision. Meanwhile, Kaito arrives at Cape Kadokura to find the 7th Kimijima report. When Kaito looks at the red gate through his phone, he finds a green icon and asks Genji to confirm that it is the real report. Genji confirms that it is the report, but Mizuka interrupts them before they are able to download it. At the hanger, Junna is able to spot a lag in Gunbuild-2's movement when it walks. Subaru then hands over the control laser to Akiho and he runs over to the robot to observe how it walks.
At Cape Kadokura, Mizuka tries to persuade Kaito to give up his search for the Kimijima reports. Mizuka's reaction convince Kaito that she knows something about what is happening. They argue until the sound of the Kagome Kagome ringtone starts playing from Mizuka's phone. They both receives an anonymous phone call. At the hanger, as Subaru observes the robot in motion, a strong gust of wind topples the robot as it begins to fall in Subaru's direction.
Mizuka falls off a cliff
Back at the shrine, Mizuka accepts the phone call and a piercing sound erupts from the phone until Mizuka the call. Then Mizuka's mechanical legs suddenly start moving towards the cliff. Mizuka tries to turn off the machine, but she is unable. She calls for Kaito's help. However, despite his best efforts, he is unable to halt Mizuka's course. It is then that Mizuka resigns herself to her fate and tells Kaito to stop trying to save her before she takes him with her. Before falling off the cliff, Mizuka instructs Kaito to tell Misaki that she thanks her for the mechanical legs. Then she falls off the cliff and Kaito screams in anguish at the sight of Mizuka's limp body.
