Plot
Azuma Kazuki is a young boy living with his family on Treasure Island (宝島), a floating island several thousand feet above Earth that is inhabited by giant sentient robots called Buranki (ブランキ), all of which are "sleeping". However, several of the Buranki are killed to wake up, forcing Migiwa Kazuki, his mother, to send Azuma, his identical twin sister Kaoruko, and their father down to Earth and is killed in a Buranki named Oubu for safety, leaving her behind.

Ten years later, Azuma, returning to a post-apocalyptic Shinjuku is captured by the authorities, but was saved by his childhood friend Kogane Asabuki, a user of a sentient weapon known as Bubuki (ブブキ), which also forms a Buranki's limbs. Discovering he is a Bubuki-user himself with the Heart of Oubu, Azuma and Kogane unite with three other Bubuki-users: Hiiragi Nono, Kinoa Ōgi and Shizuru Taneomi, to work together to seek and revive the lost Oubu, and discover the hidden truths behind the Buranki and the mysterious Reoko Banryū's tyranny over the post-apocalyptic Japan with her own Buranki: Entei.

Oubu
is a powerful Buranki once owned by Migiwa Kazuki. When the Buranki on Treasure Island started to awaken ten years prior to the series, she had her husband and two children sent down to Earth with it, crash landing into Japan's shores and causing much destruction in its wake. At some point, its limbs were reverted into Bubukis and returned to their owners, and all that remains is its skeletal husk stored in an underground Buranki Jail. In the present day, Oubu's Bubuki has been inherited by the children of their owners, now working with Migiwa's son Azuma, who has inherited its Heart, to reawaken Oubu and travel back to Treasure Island to find out the truth behind the Burankis.

After Kogane rescues him and he meets the other Bubuki-users, he awakens his own Bubuki while trying to protect Righty:, which he unknowingly had inherited from his mother. As a Heart-user, Azuma is able to awaken and assemble Oubu, as well as act as one with it as its main controller, though as such, when Oubu takes damage, he would also feel the pain, and Oubu's performance also depends on his emotional and physical condition.

Entei
is a Buranki owned by Reoko Banryū, rivalling Oubu in terms of power. 24 years prior to the series, a battle between the two Buranki ended up with Entei's limbs being permanently torn apart and destroyed, while Reoko mysteriously gained immortality as an outcome of the conflict. Since then, Entei uses a pair of pseudo tentacle-like limbs to battle, with Reoko constantly on the hunt for spare Hearts and parts strong enough to withstand Entei's power to once again complete Entei and exact her revenge on Oubu and Migiwa. Her comrades, dubbed the, however, now having lost their original Bubuki, use their own substitute Bubuki they won off from other users through battle, and continue to support Reoko till current day, even though their current weapons are not strong enough to form up Entei anymore.

 * A young woman who once wielded, she and Migiwa were best friends back in high school. When she was told she only had three years left to live, she decided to make Entei and the other Buranki known to the world, but Migiwa interfered in this to save her: Destroying Entei's limbs with Oubu, Migiwa crushed Entei's Heart, causing a new Core to painfully manifest within Reoko, turning her into Entei's new Heart and granting her immortality as a result. Following the years, having been locked up in Migiwa's mansion, Reoko becomes conflicted about her unchanging appearance despite the many years that has passed and starts to feel hatred and repulse towards Migiwa. Released upon Migiwa's departure to Treasure Island, Reoko reunites with her comrades as they overthrow the government that has been killing Bubuki-users, creating a new one that serves as her puppet for her plans to exact revenge against Migiwa for what she has done to her.
 * Being Entei's Heart herself, her powers are similar to Azuma's, though with every time she controls Entei she brings fatal damage onto herself, and despite her body being able to revive and restore itself to a near-perfect condition, the brain-damage she receives cannot recover, her memories eventually being eaten away every time she dies.
