In the newly formed Shiniki district of Tokyo, Zen Seizaki is a diligent public prosecutor at the Tokyo District Public Prosecutors Office. Assigned to a case involving false advertisement, Zen—along with his assistant officer, Atsuhiko Fumio—investigate Japan Supiri, a pharmaceutical company that had provided fabricated clinical research on the company's new drug. While investigating the file of Shin Inaba, an anesthesiologist connected to the crime, the case takes a dark turn when Zen finds a page stained with a mixture of blood, hair and skin, along with the letter F scribbled all across the sheet. As he investigates further, the case goes beyond Zen's imagination and becomes vastly complex, challenging his sense of justice and his knowledge of the truth. Digging deeper into the investigation, Zen begins to uncover a concealed plot behind the ongoing mayoral election and ties to many people of interest involved in the election and those closer than he thinks. The case grows more severe and propels Zen into an unforeseen hurricane of corruption and deceit behind the election, the establishment of the Shiniki district, and the mysterious woman associated with it all.

The world of Lingalind is surrounded by a mystical wall with seemingly nothing beyond its confines. Worshipped as the mother of the land, the wall delivers celestial gift capsules called Rakuho'' to locations across the continent. Arriving once a month, the capsules contain metallic armbands that allow the wearer to transform into a mechanical being known as a Briheight. As a result, Lingalind is thrown into constant turmoil by its warring nations, all hoping to strengthen their military prowess by procuring the offerings for themselves. One day, a Rakuho crash-lands in the countryside with an unexpected inhabitant—a mysterious black-haired man. All eyes are set on this strange newcomer, who calls himself Back Arrow, when he claims to have hailed from a place beyond the wall—a revelation that can potentially unravel Lingalind's entire dogmatic foundation.

After the final downfall of the rogue Bakugan Naga, peace was brought back to Vestroia. With the help of Danma Kuusou, his companion Pyrus Dragonoid, and other Battle Brawlers, the Infinity and Silent Cores were combined and the realm was recreated. However, New Vestroia will not be given any respite as humanoid alien invaders, the Vestals, arrive and conquer the Bakugan world in one fell swoop. Armed with a fearsome machine capable of restricting Bakugan into their ball forms, they aim to enslave the race as a form of entertainment. Now, the only force standing in their way is the Bakugan Battle Brawlers Resistance—a group of humans, Bakugan, and Vestals who oppose the idea of annihilating a sentient race. Led by Danma, they must venture into enemy-occupied New Vestroia and repel the invaders, to assure the survival of the entire world.
