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.

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]]
