Despite age, bullying is an ongoing issue. Haruyuki, a student attending middle school, had been a victim of bullying due to his weight. However, he found refuge by playing squash on the network. One fine autumn day, he encountered a magnificent and elegant person named "Snow Black," who introduced him to a program called "Accel World." This software boosted an individual's cognitive skills, but at a cost. Transforming into a "Burst Linker," Haruyuki no longer remained a social pariah but instead became a devoted knight, committed to safeguarding his beloved princess.
