Following the Dusk Taker incident, Kuroyukihime remembers enlisting Haruyuki Arita into the 'Brain Burst' system, granting users the power to speed up their thoughts to the point of temporal suspension. Haruyuki has since gained recognition among fellow Burst Linkers, aiding Kuroyukihime in her pursuit of the game's highest rank. However, a disruptive event during a territorial skirmish against Nega Nebulus leads to Haruyuki and his companions being expelled from the program. Simultaneously, a citywide malfunction of surveillance cameras signals a larger issue tied to the Brain Burst anomaly. To restore their accelerated abilities, Nega Nebulus must rally the various legions to identify the root cause behind the malfunction and rectify the situation.
