In the near future, the PhoneDroid--a device which features augmented reality--has risen in popularity in Tanegashima.
On that island, Central Tanegashima High's "Robot Research Club" is about to have their club disbanded.
Despite their predicament, Kaito Yashio, one of only two members in the Robot Club, couldn't care less and would rather play a robot fighting game.
His counterpart, the reckless club leader Akiho Senomiya, ignores Kaito as she strives to keep the club from being disbanded by completing their giant robot.
One day, for some odd reason, Kaito finds an A.R. (augmented reality) annotation titled "Kimijima Report."
It contains details about a plot involving the entire world written by a man named Ko Kimijima.
