Robotics;Notes

The Robot Research Club is shocked to hear that not only has Doc been rushed to the hospital, but he's also considering closing his shop; Junna tries to encourage him to keep the shop open, but her fear of robots makes it difficult.

Experiments with the magnetic monopole get underway, and more information from the Kimijima Reports comes to light; details about an impending solar storm are revealed, along with a warning of a robot uprising.

After a solar storm knocks out power all over Tokyo, robots throughout the city run berserk and attack; it's up to Kaito to shut down the robots and save the entire Tokyo metropolitan area somehow.

Airi finds her existence threatened when major maintenance is scheduled for the IRUO. server; Airi clings to the hope of a snowy miracle; Kaito learns more about her past.

The Robot Research Club's newest giant robot, GunBuild-2, is finally complete; both Exoskeleton Co. and Mizuka catch wind of Kaito's activities surrounding Kou Kimijima.

After the accident with GunBuild-2, the school's vice principal shuts down the Robot Research Club for good and orders that all the club's robots be dismantled.

At last, the big robot expo in Tokyo gets underway; the diminished Robot Research Club finally gets to show off its robot, and Akiho finally gets the chance to see her sister again.

Chaos erupts at the Robot Expo as Misaki starts destroying robots left and right; slowly, but surely, Kaito begins to learn the truth behind everything.

With five billion lives at stake, Akiho declares that she will defeat Kou Kimijima.

Working through the night, the Robot Research Club members and the throngs of volunteers finish modifying GunBuild-1 before the Black Hole Bomb can be launched; the club members also devise a number of strategies for the upcoming final battle.

Kaito and Misaki face off in a showdown with only minutes left until the BHB rocket is launched.
