BUILD-DIVIDE

Neo Kyoto is a city with an AR infrastructure and ruled by the King but is also a world where the social and economic status of a person is determined solely by their skills in a game called Build-Divide. One day, Teruto Kurabe is wandering around the city with a piece of bread in his hand, and discovers a girl named Sakura Banka who is being attacked by a thug, so he uses the power of a mysterious card in his possession to save her. Witnessing his powers, Sakura speculates that Teruto must be highly skilled in Build-Divide and requests a battle with him. She has been searching for a powerful player that could help her win through the Rebuild Battles, which would allow her to challenge the King. However, Teruto has lost all his memories…

Teruto reluctantly accepts Sakura’s offer to take part in Rebuild Battles. While they are walking in the city together, she realizes that Teruto is wearing a uniform from Komoku Academy, which is the same school she is a student of. Guessing that Teruto must be a student of Komoku Academy, she takes him there and discovers that he is indeed enrolled at the school. For some reason, one of the only things that Teruto remembers is his strong desire to battle the King. They search the school grounds to find other Build-Divide players, but a second-year middle school student named Hiyori Munenashi suddenly appears before them and…

After battling Teruto, Hiyori pleads to become Teruto’s disciple, and follows Teruto and Sakura around. In order to obtain more chips, Teruto and the crew head to a place which is rumored to be where Build-Divide players gather. However, before they arrive at the location, they discover that someone has already defeated all of the players, so they are forced to search in another area. On their way there, Teruto is pulled into a crowd of protestors and gets separated from Sakura and Hiyori. In the midst of the confusion, a young man named Naomitsu Enjo appears and helps Teruto. Naomitsu Enjo expresses his anger towards the system of Neo Kyoto and…

Three years have passed since the collapse of Neo Kyoto. The city has changed completely, and the King's messengers, called KUGE, are spreading throughout the city. In the midst of all this, a girl runs away from the KUGE. Even as she is attacked, she does not fight back. However, until three years ago, she was considered the strongest girl in Neo Kyoto... The girl has been driven into a corner, desperate without escape. There, another girl appears, this one wearing a hood. She says, “It's been three years... I finally found you." She holds out her hand toward the girl. She is Hiyori, Teruto's apprentice.

Hiyori asks Kikka for help. Kikka thought she could never move forward, but she decides to follow Hiyori's idea. She is led to the hideout where Hiyori lives with her classmates. Kikka is warmly welcomed when Hiyori introduces her as a new member. However, Kikka hesitates to say her name to not be recognized as the former King. Although Kikka is able to get by with a pseudonym, she is brought to tears over their meal and comforted by the members who explain the cause of the collapse of Neo Kyoto was caused by the previous King named "Kikka"...

The KUGE messengers who appeared in Hiyori and the others’ hideout were after Kikka. Kikka doesn’t want to be the cause of any more casualties, so she finally decides to grab her deck and fight. However, since it’s been three years since her last battle, Kikka has forgotten how to fight and makes a fundamental mistake that lands her in a pinch. “I wonder if it was reckless of me to fight...” Kikka thought. But then, the memories locked in her mind returned. A time when she was a child. The time when Teruto taught her Build Divide..
