BUILD-DIVIDE -#000000- CODE BLACK

Neo Kyoto is now a city in ruins, looking nothing like it did before. The people are being rounded up by the King's servants, known as KUGE, and deposited into "Barrels" to steal their magical power. All in order to keep the King going... And now a girl appears, with the KUGE in pursuit. She's the former King, Kurabe Kikka. Although she was once known as the most powerful King in Neo Kyoto's history, even Kikka is helpless against the KUGE, and is constantly on the run from them. After all, Kikka has no Build-Divide deck in hand. Day after day, she continues to flee with no respite, consumed by all kinds of regrets. Now that she's on the brink of despair, who should reach out a helping hand to her but...? In the ruins of Neo Kyoto, the two girls take each other by the hand. And now, their battle is about to begin... the one that will lead them to the person that they both cherish.

One day, six cards known as the "Six Desires" were born with the power to change fate. Six fighters were chosen, and would come to possess those six cards. What awaited them was the “Fated Clash“, where they would fight each other until the end, and the last one standing would have any wish granted. A youth named Akina Myodo, who wants to help his frail sister, participates in the Fated Clash to have his wish granted. And thus, he throws himself into battles with powerful fighters.

A new kind of battle of abilities for a new generation is about to begin! It all started on a regular morning like any other. Akira Shiroyanagi is a high school kid who loves nothing more than konpeito candy and games. One day, he ends up in a fight due to a mysterious girl named Mion. Mion then tells the people she had gathered that they no longer officially exist in any records. They were given powers and were about to be test subjects. Akira makes up his mind to use his powers to climb up the ranks and then crush this organization.

Riding the bus one day, Sakurakouji Sakura looks out the window to see people being burned alive with a blue fire and a boy her age who's unharmed and standing over the people. She comes back to the site the next day and there are no corpses or evidence of any kind of murder, just a small fire. She then goes to class to find there's a new transfer student, Oogami Rei, who looks exactly like the boy she saw before and wears a black glove only on his left hand. Oogami is a Code Breaker, one who "does not exist". He is a seemingly cold-blooded killer who follows the principle of "an eye for an eye", to "use evil against evil". Convinced that killing is not right, Sakurakouji sets out to stop him and penetrate his icy heart.
