Delta Battle

The Delta Battle (デルタバトル) is the name referring to a major event created and hosted by “The One”, and was the titular race that drove the plot of Delta Episode.

Initially believed to have been a race made for fun, it was soon revealed to be a sadistic death game, split into different checkpoints referred to as “stages” and spanning across space, time, and virtual reality.

The Delta Battle was initially a vehicular race, but this element was dropped later in the event. The prize for winning would turn out to be The One’s power and position.
