Humans and monsters shared the Continent in a delicate balance for over a thousand years, but it all came crashing down. The most powerful fiend, Kayblis, seized power over the Monster Realm and led a colossal army on an invasion of the Human Realm. Unable to stop quarreling amongst themselves, the human nations were trampled. Two weeks after the war began, the death toll for humanity reached approximately 12,000,000. Yet mankind still couldn't unite, and the turmoil between the world's leaders continued. Just as the demise of humanity, the worst case scenario, weighed heavy on everyone's minds... "Everyone should just work for me. I'll crush that Monster Army no problem." It was Rance, back from an adventure with his companion, Sill. There was an uproar among the world leaders: The Kingdom of Leazas's Queen, Lia Parapara Leazas. The Kingdom of Zeth's Viceroy, Magic the Gandhi. The Republic of Helman's President, Sheila Helman. The Free City Alliance's Representative, Copandon Dot. The eastern island of Nippon's Lord, Kou Oda. The world's largest religion, Alicism's Pope, Crook Mofus. ...And they were also Rance's women, so they all agreed. Rance became humanity's supreme leader and their final hope. Over 6000 years a minuscule creature called Kayblis fought and slaughtered his way to the very top of the Monster Realm. A conceited man named Rance, who declares all women to be his, lives a carefree life and finds his way to the top of the Human Realm. Both men put the survival of their entire race on the line in an inescapable struggle to the death. [From [url=http://mangagamer.org/rance/10/] MangaGamer[/url]]

This game is not considered part of the official Rance universe timeline, forking off after the events of Rance 4.2, as a "What if" episode. However, many characters and ideas featured in later Rance games originated in Kichikuou Rance. The game begins at the start of LP0003. The warrior Rance, accompanied as always by his faithful slave Sill Plain, has been living as the leader of a group of bandits in northern Helman after killing their previous leader as part of a job given to him by the Keith Guild. While Rance greatly enjoys the raping and pillaging that comes with being a bandit leader, the guilt-ridden Sill believes that he is in danger of losing what remains of his conscience and genuinely becoming a villain. After attacking the city of Golak, Rance's group alerts the attention of Ruberan Tser, commander of the Helman volunteer army, who launches a counterstrike on them during their second attempt at pillaging the city. Unable to fight against a genuine army, the bandits are quickly destroyed, Sill is captured by the Helman Army and Rance is forced to flee for his life. Rance evades the Helman army for several days, with both his equipment and health steadily declining all the while, before he finally passes out from fatigue along the Leazas/Helman border. He is found on the verge of death by Kentou Kanami, the personal ninja of Leazas' queen and Rance's longtime admirer Lia Parapara Leazas, who brings him to Leazas castle. After three days of recovery, Rance finally regains consciousness and, completely humiliated by his defeat at Helman's hands and desperate to rescue Sill, demands that Lia give him the Leazas Army to destroy the enemy nation. Finally seeing an opportunity to have Rance to herself, Lia agrees on the condition that he first marry her, which Rance reluctantly accepts. As the new king of Leazas, Rance sets his first steps on a path that will lead to either world domination or death.
