Tortov Roddle is a man of few words on a journey through a calm and obscure new land, interacting with its inhabitants along the way. As he rides on his long-legged pig through the desert from town to town, he observes the interesting and quirky customs of the locals and reminisces about his past.

In a certain distant land, home to numerous intriguing towns and people, many wondrous sights can be found. Traveler Tortov Roddle encounters a curious patch of red berries and after sampling one, happily indulges himself with more. He soon realizes, however, that this delectable fruit has considerable hallucinogenic effects and finds himself partaking in his greatest trip of all. Elsewhere, a little girl finds brief yet fantastical escapes from her everyday life. In yet another city, residents are baffled when giant black apples begin raining down from the sky, but find that they may have use for them. A journey into the extraordinary, Aru Tabibito no Nikki Specials explores the surreal occurrences of its setting, and how the land's inhabitants react to certain dreamlike experiences they encounter.

In the original storyline as aired in Japan, Dairugger XV was simply an exploration robot, as well as an intended peace-keeping force. The Earth is in a time of prosperity. The president of the Terran League (the "Galaxy Alliance" in Voltron) launches a mission to explore beyond the galaxy. After commencing its mission of exploration, the starship Rugger-Guard is attacked by a ship of the Galbeston Empire. Dairugger, the super robot, is deployed in order to defend the Earth. It is somewhat by fate that they must help the people of Galbeston find a new planet before it explodes, and liberate it from its despotic Emperor. In the Japanese version, it does not have anything to do with King of the Beasts GoLion, as opposed to the U.S. version, Voltron: Defender of the Universe. There are three assault team units: Land, Air, and Sea. There are a total of 15 parts referred to as "Rugger," which can combine together to form the super-robot Dairugger. The design of the 15 separate Rugger units came from the sport of rugby, since 15 players are required to form a rugby union. The U.S. version would rename the "Galbeston Empire" to "Drule Empire," along with editing a fair amount of violence and sexual content to keep the show safe for general audience broadcast.

In Thrace, Arion is taken from his mother Demeter by the god Hades. In the Underworld, Arion is trained to be a warrior. His training is driven by revenge: Arion was told that his mother's blindness was caused by Zeus and Zeus' death will remove the curse. Finally, Arion and Geedo (a huge ape-like creature who had become Arion's friend and companion) left the Underworld to find Zeus. Seneca, a small thief, makes off with Arion's sword and this leads Arion to his first encounter with the forces of Zeus, commanded by his daughter Athena. Arion is captured but is later set free by Lesfeena, Athena's mute serving girl. As Arion rejoins Geedo and Seneca (and worries about Lesfeena), the forces of Zeus and Poseidon face each other in battle. In the background sits the scheming Hades, and the calm Apollon who seems to have plans of his own.
