Orochi Saga(Seasons 1-4)
During the ancient times, a being was born from the Earth itself, named Orochi. A divine being who calls itself "Gaia's Will", manifested through floating emotions and substances of nature, and became the equalizing force between humans and nature. Orochi was nature's guardian and was granted with many of its powers. It gained followers to its cause and eventually formed a clan. The eight strongest warriors of that clan would go on to be known as the Hakkesshu. As the mankind began to grow in numbers, however, the natural balance began to crumble.

Goenitz assigns the task of observing Rugal to two other Hakkeshus, Mature and Vice, believing that he could be a suitable host for Orochi.

Rugal, certain he can join the Hakkeshu's ranks, decides to host The King of Fighters in 1994, with an additional twist; fighters must form a team of 3 to compete and represent a country. Now he awaits on his battleship, the Black Noah, waiting to see the teams that will participate.

NESTS Chronicles(Seasons 5-7)
NESTS is a secret organization that had control over all kinds of criminal activity throughout the world. Their dealings made many corporations around the globe to go bankrupt. Their members were wanted by all investigation agencies, but no one could find their headquarters, since their true location was on a satellite hovering around the world. NESTS had a high-technological arsenal of weapons and machines at their disposal, which allowed them to research on many fields of science, specifically on bio-engineering.
