The Southern Kingdom is the origin and the peak, where Gugugaga penguins began to settle in the farthest reaches of Pacific marine debris. The town smells terrible, and houses are built by piecing together paper-thin drifted iron. They gratefully accept human trash. The town is filled with trash-collecting Gugugaga, those gathering empty cans (which serve as currency), families, and security guards. Infrastructure is somewhat established. There are violent individuals and all sorts of characters. There are many factories. There is also a Gugugaga bulletin board where information on dangerous individuals and cheap shops is shared. It's like the Japanese countryside from two generations ago. Drum can bonfires are everywhere in the city. These are the only streetlights. The Eastern Kingdom has no trash and is home to many Buddhist temples, shrines, and sanctuaries designated as national treasures. Sects are divided, with the Coexistence Sect being the most popular. They eat meat and fish but never forget gratitude and treat everyone equally. The Purity Sect avoids waste and does not eat meat or fish. The most extreme is the Return Sect; they don't eat at all and are mostly skin and bones. The Great Temple of the Purity Sect is a national treasure of the East, including the Kannon statue in the main hall. Many famous people come from the East, like Guga Sadao, a contributor to medical development who was extremely cowardly and found peace through herbs and various remedies. Statues of great achievers are displayed in the main hall. The Western Kingdom is naturalist and, frankly, insane. A war broke out during the final years of the Second King's reign. The king died during the war, and the current Gugugaga King was hastily enthroned afterward.

He looks like a normal Gugugaga, wearing a toy crown and holding a dirty tin can. It is said that this Gugugaga was among the original members of the first drift. He is smart but weak. He is beloved by everyone. His activities include directing the development of the town. The first king arrived 98 years ago, starting it all. Three years later, they split into West, East, and South. Fifty years ago, the Second King was enthroned, and the South-West War occurred. Five years ago, the Third King, the current Gugugaga King, was enthroned. There is a diary-like record written by the kings called the "Izumadara Sada Writings." A monk from the East named Tsuchishiro protected the first king's writings, saving 29 out of 30 volumes. For the second king, due to the war, only 5 out of 20 volumes exist, and the volume numbers are scattered. All these writings are designated as national treasures.

Gugugaga known as handymen. They find screwdrivers and such in the filthy city to repair items, providing washing machines and food. This is the basic profession of the town. They walk through the streets pushing dilapidated, drifted carts. Recently, they have been selling pins and empty cans to tourists. Most merchants act like smooth-talking Japanese salesmen from a bygone era. Gugugaa~ (It's cheap right now~)

Gugugaga carrying cork-bullet rifles used for festivals. They serve as the King's guards. They also handle the capture of seabirds and deal with wild and marine animals. They are both fishermen and soldiers. The cork rifles were likely discarded festival items from Japan that washed ashore. Everyone calls the cork rifles "Type 64." Since reloading cork pistols and rifles is quite a hassle, they also attach bayonets to the cork rifles. There are about 30 of them.

They carry cork-bullet rifles. They ride on warships made from modified drifted fishing boats, equipped with rapid-fire cork rifles and drum cannons. They are strong. There are about 20 of them.

A very rare profession in this town. They are skilled at drawing in a style reminiscent of Ukiyo-e. They mainly painted the "Battle of the Sea Beasts" and war scenes from the South-West War. One artist's work in this country is designated as a cultural property. He is the one who painted the "Battle of the Sea Beasts" and the "South-West War Illustrations." His name is Gugaoka.
