Overlord, Volume 6 (Overlord #18-20)

The day of the battle with the Great One fast approaches. Can Zaryusu unite the lizardmen tribes before they're all wiped from this earth? The Red Eyes have agreed to an alliance, but the Dragon Tusks will be trickier. They prize strength above all else-meaning Zaryusu will need to defeat their chief in combat before they'll even think of hearing him out!
