Oh My Goddess! Vol 41

From the Dark Horse edition

Thrym - in Norse legend, the frost giant who once stole Thor's hammer! But in Oh My Goddess!, Thrym is no legend, but a very real buffed-out demonness who stands guard over the next chamber of Hell, aiming to stop Keiichi and the goddesses in their journey to free Hild. To defeat this massive door warden, spells won't be enough - and Belldandy must engage in something shocking for her... hand-to-hand combat! Each volume of Oh My Goddess! contains fan art, letters, and commentary from the creator.
