Sodom (Overflow)

An era in which civilization spreads centered on two very different cities, Scallops and Sodom. Scallops is an island-like city surrounded by 24 strong towers that are inaccessible like a temple. Sodom is a complex and densely populated city with a thick black smoky, inhabited by mutants of life forms that seek to obtain the precious substance called ‘irum’ from the scallops and other by-products. Indra, the leader of Sodom longs for Scallops, and sets out to build a giant cannon in the center of the city to take everything from Scallops, but his ambition eventually awakens Lot and Ran, the original origins, and causes war.
