Summary [AniDB]: It is the end of June 2019. A device called the PhoneDroid, more commonly called the PokeCom, has gained wide-spread acceptance.
On the island of Tanegashima, the Central Tanegashima High School`s Robot Research Club is on the verge of disbandment. [Yashio Kaito] shows absolutely no interest in the club despite the situation and being one of the club`s only 2 members. He is fully absorbed in developing a robot fighting game. His attitude causes friction with [Senomiya Akiho], the other member. Akiho is the reckless Club President. She is determined to save the club by completing the construction of a giant robot.
One day, whilst Kaito was in a park, working on his computer game as usual, he hears a girl`s voice and discovers the A.R. annotation of the Kimijima Report. It is an allegation of a plot by one [Kimijima Kou]`s with world-wide implications.
