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.

Backed into a corner by Brahman's overwhelming strength, The US Army is finally forced to order all troops to retreat. Touko, however, realizes that Justice is still on the battlefield, and is too anxious to leave. Meanwhile, BB suddenly arrives to take on Cal, but her "absolute boundary" ability forces him to fall back on his last resort. And as Justice watches the desperate battle unfolding before him...

Having inherited BB's wishes, Seigi takes Wiseman's advice and lies low in a mountain hideout for a year. Izzy and Tom have spent the year with him, along with Tamaki, who joined them on the mountain, and Seigi has finally grown strong enough to overpower Izzy. Then one day, a mysterious enemy attacks their hideout, leaving behind a video letter with footage of Arya in America, near the location of the third ruins.

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...
