Arifureta: From Commonplace to World's Strongest Zero (Manga) Vol. 7

Newly awakened from its long slumber, the divine beast Leviathan is free, and its dreadful power threatens to sink the entire city of Andika beneath the waves. The Liberators and Melusine Pirates will do whatever they can to save the city's people...but Leviathan isn't the only threat they're dealing with. The Church's Templar Knights are still out for their heads, and they don't care how many innocent lives get caught in the crossfire!
