During a summer camp, 15 children (8 boys and 7 girls) find a grotto by the sea. Deep within, they discover working computers and some electronic equipment, and later the owner, a man who introduces himself as "Kokopelli". Kokopelli claims to be a programmer working on a brand new game, in which a large robot has to defend the Earth against fifteen alien invasions. He persuades the children to test the game and enter into a contract. Fourteen of them agree, but one of them is kept from entering the contract by her older brother, and a moment later they all mysteriously awaken on the shore, believing what happened was just a dream. That night, two giant robots appear by the beach. A small creature calling himself "Koyemshi" also appears and claims to be the children's guide. He then teleports them into the black robot, with Kokopelli already inside and controlling the black robot in order to defeat the white enemy robot. During battle, he gives the children a brief tutorial on how to pilot the robot as he destroys the enemy. Once he has finished, he tells the children that they are on their own now and sends them back to the beach. As the children are teleported out, one child observes Kokopelli whispering "I'm sorry". Takashi Waku is the first pilot of the robot, which is named "Zearth" by Maki Ano. Upon winning the fight, Waku is accidentally 'knocked' into the sea from a ledge on Zearth's chest by Jun. The second pilot, Masaru "Kodama" Kodaka, dies unceremoniously after defeating his opponent. Koyemshi explains to the children that Zearth runs on life force, and the cost of every victory would be the life of its pilot. It is also revealed that Waku fell into the sea after getting 'knocked' by Jun because Zearth had drained his life force; he was already dead. Thus, the children must now defend the world and face the many trials and tribulations of doing so, including the fact that ultimately none of them will get out of this situation alive.

An anime television series adaptation was directed by Hiroyuki Morita and produced by Gonzo. It was broadcast in Japan from April 8 to September 25, 2007, on Sun TV and Tokyo MX, as well as other stations. Episodes were released in Japan on eight DVDs between July 25, 2007, and March 26, 2008. On September 4, 2014, North American anime licensor, Discotek Media announced their license to the anime with an English subtitled DVD release in 2015. The original soundtrack is by Yūji Nomi. The opening theme was "Uninstall" (アンインストール, An'insutōru), and the ending themes were "Little Bird" (episodes 1–12) and "Vermillion" (episodes 13–24), all performed by Chiaki Ishikawa. Regarding differences between the stories in the manga and in the anime, Hiroyuki Morita, who directed the series, wrote in his blog that he dislikes the original story and has, in some ways, been making changes to the plot for that reason. He also wrote that, at one point early in the development of the show, he asked manga author Mohiro Kitoh if he could find some way to save the main characters — the kids who must pilot Zearth. He wrote that Kitoh responded that his choice was fine as long as the changes did not involve "magical solutions" to the story. Morita closed out the blog entry with the statement "The director of the animated version of Bokurano dislikes the original manga. From here on out, you can't expect the animated version to expand on what you might find appealing in the original. So, fans of the original, please do not watch the animated version from now on".

Bokurano was adapted as a light novel series entitled Bokurano: Alternative (ぼくらの〜alternative〜, Bokura no Orutanatibu). Five volumes written by Renji Ōki with illustrations by Mohiro Kitoh were published by Shogakukan between May 2007 and June 2008.
