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.

After fooling around too much and burning through all his funds, Rance reluctantly takes his slave, Sill, and his pet, Athena 2.0, with him on some adventuring work. But while fighting through a dungeon, they get lost in the caves and can't find any way out... After some trouble, they eventually arrive at a mysterious castle inhabited by youkai.

On a certain day in April, LP 2, the great eastern country of Leazas fell after being invaded by an elite force from the militaristic northern country of Helman led by Imperial Prince Patton. With Patton's forces are supreme beings of great power, who are unable to be wounded by any of Leazas's strongest warriors—fiends. The castle was occupied in a matter of moments and Leazas's ruling monarch, Princess Lia was taken captive. Is this the end of Leazas? As the mighty nation becomes a thing of the past in but a single night, one ninja flees the castle, taking with her one of the country's national treasures and a simple message from the princess. With the nation's last shred of hope, she heads to the Free City of Ice in the west. She heads to the brutal warrior, who has nothing in his head but thoughts of beautiful women.

While the plot has overall remained unchanged, several characters have been added and their backgrounds given more depth. It's also the first Rance game to include voice acting.

Despite previous failed invasions, the nation of Helman allies with demons and successfully captures Leazas Castle, compelling Princess Lia to seek help from the adventurer Rance. To confront this new threat, Rance must gather three sacred royal treasures and revive the legendary magic sword Chaos. However, having previously sold some of these treasures for money, he embarks on a quest to retrieve them, which involves rescuing a girl named Laura from a monster called Liss. During his journey, Rance encounters fellow adventurers and faces various challenges that test his abilities and resolve. He joins forces with Maria, leader of the Leazas Liberation Army, to rescue citizens and mount a resistance against the invaders. Meanwhile, internal strife within Helman complicates the conflict, as Commander Patton grapples with political interference and suppressed reinforcements. As battles rage and alliances shift, Rance and his companions strive to reclaim Leazas and overcome the demonic forces. [Based on Wikipedia]

This is a side-story in Rance series, released shortly after the fourth game, but dedicated to an entirely different quest. All kinds of troubles are happening to a factory where a new Happiness Medicine is being developed. The mercenary Rance is hired by the manager to investigate the source of these troubles. First task: clear the factory of the monsters... This is a RPG with turn-based combat and strong adventure elements (menu with command verbs such as "Examine", "Talk", etc., at every given screen). Unlike the previous Rance games, the battles do not allow free movement on the screen, and are carried out in a more traditional Japanese-style way. There is no physical movement in the game; hostile areas (dungeons) are also explored by choosing menu commands. As in all other Rance games, there are explicit sex scenes in this game.

Rance 4.2: Angel-gumi is the second part of the story that began in Rance 4.1: O-Kusuri Koujou o Sukue! rather than an all-new Rance adventure. The hero continues to investigate the weird occurrences connected to the Happiness Medicine Factory. Since the story picks up directly where it ended in the prequel, Rance begins his adventure going against the Angel Army. Nothing has changed gameplay-wise; as before, interaction with the game world is done through menu commands everywhere, including dungeons. The combat system has also remained exactly the same as in predecessor. [From [url=http://www.mobygames.com/game/rance-42-angel-gumi]Moby Games[/url]]
