Gantz manga volume 7 contains volumes 19-21 in an omnibus format and features story and art by Hiroya Oku.

After earning enough combat points, the Gantz alien fighters are given three choices: freedom, better weapons, or resurrect a dead Gantz warrior. Each fighter has suffered greatly, and each has experienced devastating loss. But are they willing to further risk their own lives to bring back a fallen friend, and can they bring themselves to abandon the comrades who have bravely fought beside them?
