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]

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.

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.
