Makai Toushi SaGa

Standing in front of the tower, the hero and party learn that they cannot climb it to paradise without first unsealing its base door. In the base world, three kings named Armor, Sword, and Shield fight for dominance using a piece of legendary equipment corresponding to their names. Visiting King Armor, the party learns that he is in love with a girl who returns his feelings, but cannot marry him, as a bandit holds her village hostage in return for her love. They defeat the bandit, and the king gives them his armor in gratitude. King Sword attacks the heroes, who vanquish him and take the sword. Lastly, King Shield is murdered by his own steward, and after a short fight, the party recovers his shield. Restoring the items to a statue of a great hero, they receive the Black Sphere, but are attacked by Gen-bu, the first of four fiends controlled by Ashura. They defeat him and use the power of the Sphere to enter the tower.

They climb the tower and come to another door; inside lies a second world surrounded by large bodies of water. By navigating caves, they find a floating island which allows them to travel around the world by air. They locate an old man, Ryu-O, and solve his riddle to obtain the Airseed, allowing them to breathe underwater and enter the undersea palace. They encounter the second fiend, Sei-ryu; they defeat him and recover half of the second sphere. Upon returning to Ryu-O, he reveals himself to be the guardian of the other half of the sphere, and the two halves form the Blue Sphere.

Using the Blue Sphere to continue up the tower, the party comes to a world of clouds, dominated by Byak-ko and an army of thugs. They learn that Byak-ko recently wiped out an underground resistance movement, except for Millie and Jeanne, the two daughters of its leader. The party temporarily joins Byak-ko's gang to find the girls, and attempt to defend them until Millie betrays Jeanne and the party is captured. Breaking free, they confront the fiend, who tries to kill Millie; Jeanne takes the blow and the party engages the fiend. They defeat him, recover the White Sphere, and continue their journey.

The fourth world is a post-apocalyptic wasteland; Su-Zaku roams the surface defended by an impenetrable forcefield. The party retreats to an abandoned subway for refuge and meets Sayaka, who directs them to the nearest town. There the party is confronted by the leader of a biker gang, So-Cho, but his sister Sayaka intervenes and the two groups agree to work together to defeat Su-Zaku. As they gather the needed parts for a device to deactivate the forcefield, So-Cho sacrifices his life to guide the party through an atomic power plant. Beasts then ambush the town, and Su-Zaku kidnaps Sayaka. The party defeats Su-Zaku, earns the Red Sphere and travels on.

Climbing the tower, the party discovers the remains of a family that attempted to reach Paradise but failed, and a library suggesting Ashura is controlled by someone else. They encounter him at the top, guarding the final door; he offers each of them control of one of the worlds, but they refuse and defeat him. Before they can pass through the door, a trap drops them to the bottom floor. Encountering the allies they made along their journey, they decide to rescale the tower. As they climb stairs that wrap outside of the tower, they engage each of the fiends revived and defeat them. They find the Creator at the summit, and learn that the fiends and the tower itself are actually part of a game created by him to see heroes defeat evil; for succeeding they would be granted a wish as a reward. Angry at his manipulation, they reject the reward and challenge the Creator, who insists that because he created everything he was allowed to use them as he saw fit. They then attack and defeat the Creator in a fierce battle. The heroes then discover a door leading to an unknown location; they consider entering, but decide to return to their own world
