The King of Fighters RX manhua series is divided in three parts:

The Beginning of NESTS EPISODE (4 volumes, 25 chapters);
NESTS EPISODE PROJECT'00 (2 volumes, 29 chapters);
The End of NESTS EPISODE (1 volume, 14 chapters).

RX covers the entire NESTS chapter with the first two volumes primarily focusing on the Zero Project. Kula and both forms of Zero are shown somewhat earlier than their premiere in the series. Most events remain relatively the same until the final volume.
