Plot
In the year 2046, Neuro-synchronization, a technology system that allows humans to manipulate their five senses, has become widespread to the point where people can access the Internet and enter virtual worlds through a device known as a Neuro-Linker. Haruyuki "Haru" Arita is a short, fat boy who has low-self esteem due to constant bullying. To escape the torment of real life, he logs in to the school's virtual world network where he plays squash alone and always gets the highest score.
One day, Haru attracts the attention of the Student Council Vice-President "Kuroyukihime" (via his high score on the school's local network squash minigame) who offers him Brain Burst, a secret program which allows a person to make time appear to stand still in their surroundings by "accelerating" their brainwaves in the real world. Unfortunately, there is a limit to how many times a person can accelerate since each acceleration costs Burst Points, and the primary way to get more points is to fight and defeat other Brain Burst users in the program's virtual reality massive multiplayer online (VRMMO) fighting game. However, if a user loses all of his or her points, the Brain Burst program will uninstall itself and block all re-installation attempts, thus permanently removing the user's ability to accelerate. In addition, a Brain Burst user may only distribute a single copy of the game. Due to the nature of Brain Burst, the installation may fail if certain conditions are not met. In order to successfully install and use Brain Burst, a prospective user must have a Neuro-Linker installed at birth and must be able to handle heightened brain activity. The one-distribution-per-user rule applies even if an installation fails. Users of Brain Burst are known as "Burst Linkers".
Kuroyukihime wants Haru's help as she wishes to reach the highest achievable level, which is level 10, and meet the creator of Brain Burst in order to learn its true purpose, but in order to do that, she must defeat five other level 9 users who are known as "The Six Kings of Pure Color," the leaders of the six most powerful factions in the Brain Burst world. Haru agrees to help Kuroyukihime to repay her as well as overcome his weaknesses.
