One day Akatsuka Justice (nicknamed Seigi), a boy with a strong sense of justice, saves a man from some street punks. But the moment he touches the stone given as a token of the man's gratitude, a strange pattern shows up on the palm of his hand. The next day, when Seigi is baffled to notice that the pattern won't disappear, a mysterious girl appears before him and demands to know where he got the tattoo before suddenly attacking him.

As he's visiting Izzy and Tom's secret home, Justice is attacked by Il, an assassin from the Kingdom who has possessed Touko's body. Meanwhile at the school, another assassin, Lakha, attacks Izzy. Now that Princess Aryabhata has taken over the rule of the Kingdom of Selinistan, the race to claim the "triggerless tattoo" has been set in motion.

After her friend Lisa is captured by Il and Lakha, Izzy works with the US Army on a mission to take her back. Justice had been held in Blue Moon's hideout for safekeeping, but is unable to remain silent when an ally is in danger and rushes to the scene. The second round of battles to rescue Lisa begins: Izzy vs. Lakha and Justice vs. Il.

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...

Izzy and the others race through the ruins... and find Justice skewered on a bed of spikes. Worse yet, his overuse of his tattoo powers has weakened his regenerative ability, leaving him on the verge of death. Izzy and Tamaki tell Tom to take him and flee while they face off against Arya to buy him more time. When Justice realizes that Izzy and the others are fighting to save him, he knows that he was wrong to become so obsessed with vengeance, and his mind turns toward saving them instead...
