In 2013, the "kyūkyokuban" or "Extreme Edition" began publication by Tokuma Shoten under the "Zenon Comics DX" imprint. This 18-volume edition, in addition to featuring all the pages from both, the "tankōbon" and "kanzenban" edition, has new cover artwork by Tetsuo Hara himself for each volume, as well as a new 30th anniversary-themed chapter titled "Hokuto no Ken: Last Piece", which is included in Volume 11.
