Maken Lovecraft Kessakushuu

A pair of decadent young men pursue the abhorrent thrill of grave robbing...a German submarine's crew is driven mad by the call of an underwater temple...an explorer in the Arabian desert discovers a hideous city older than mankind. This moody and evocative manga gets back to the dark foundations of the Cthulhu Mythos, adapting three of H.P. Lovecraft's original stories that first shaped the outlines of cosmic horror!
