After getting a taste of his own powerlessness in the previous battle, Justice returns to his intense training with Blue Rose, led by Izzy, to master the use of his tattoo. Meanwhile, the recently silent private tattoo force serving Princess Arya, the Brahman, finally makes its move by attacking the White Rose team headed by Izzy's friend Lisa.

BB, the mysterious man who suddenly appeared before Justice, takes him to a tattoo research lab run by the Kingdom in Japan. His goal is to ruin the facility and set the innocent people in it free. Upon seeing BB's overwhelming power, Justice finds himself thinking that this man is a true "hero of justice." Meanwhile, Arya has arrived in Japan and pays a visit to the tattoo ruins there in order to proceed with her plan.

The US Army's tattoo forces stationed in Japan finds out the location of Japan's tattoo ruins, where Arya currently is, and initiates an operation to reclaim the site. Justice and even Touko are included on the mission. They reach the island where the ruins are located and launch their attack, certain that they have the advantage due to their sheer numbers and higher count of original Sealed, but then Cal Shekhar, the vice-captain of Brahman, stands before them...

Justice follows the course of BB's memories, watching the man's younger self leave the US Army and offer their tattoo research information to the Kingdom of Selinistan as a gift. His goal was to grant Izzy's wish to see all tattoos in the world disappear, and searching for a way to do so in Selinistan, where tattoo research had progressed the farthest, was the method he chose. But when he infiltrated the base of Selinistan's tattoo research, BB learned a shocking truth...

The battle against the Kingdom at the ruins in America intensifies, with Izzy and Tamaki fighting Brahman members to the death so that Justice and Tom can move forward. Meanwhile, as Justice heads for the ruins to stop Arya, Cal stands in his path, made even stronger after her defeat by BB. Can Justice defeat Cal, the "strongest of the powerless," and stop Arya's true goal from being realized?
