Dragon Ball Omnibus Volume Two collects the fourth, fifth and sixth volumes of Akira Toriyama’s manga series into one volume. Viz Media’s Shonen Jump imprint has the North American distribution rights for the series, and they released this omnibus edition in September 2008. Dragon Ball is rated “T” for teen, and I would have to agree with this rating.
This volume continues the Tenkaichi Tournament (or as it’s referred to in this English translation, “The Strongest-Under-the-Heavens Martial Arts Tournament”), which is a big martial arts tournament that is only held every few years. This volume begins right after Kuririn has defeated Bacterian in the first round. All of volume four focuses on the tournament; there are five matches that lead up to the final bout. The fourth volume ends in the middle of the final fight.
The final match of the tournament continues for the first five chapters of volume five. After the tournament, Goku and his friends part ways; Goku heads on a quest to find the Four-Star Dragon Ball that had been given to him by his grandfather. During his search, Goku encounters the Rid Ribbon Army, a crime organization that is trying to find all seven of the Dragon Balls in order to make a wish to Shen Long, the dragon that is summoned by the Dragon Balls. The rest of this volume sees Goku trying to rescue the mayor of a village from a Red Ribbon Army base as a way to thank one of the villagers for rescuing him.
The first seven chapters of volume six wrap up the storyline of Goku rescuing the mayor. The rest of this volume sees Goku trying to find Bulma in order to get the Dragon Radar repaired, and then Bulma joining Goku on his quest to find the Four-Star Dragon Ball. The pair has a couple more run-ins with the Red Ribbon Army.
