Neo Domino City VS Satellite
This series starts by two distinguishable cities. One is a gorgeous and hierarchical society named [Neo Domino City]. High-class residents are called to be chosen people to live here. Another city is an old-structure and unorganized city called [Satellite], which is located on a solitude island not far from Neo Domino City. Satellite is a plant that handles all trashes transferred from the residents in Neo Domino City and recycles them. It's nothing rather than a factory where low-class people live. People who live in Satellite are called [Satellite Scum].

These two cities are completely separate and monitored by securities. They are linked only by the undersea pipeline that is used to transfer trashes from the city to Satellite plant. Satellite Scums are just a labor who can't escape from the factory in order to migrate into Neo Domino City.

Neo Domino City	Satellite

Satellite Scum Left Behind
Yusei, Taka, Blitz, Rally, Nerve, are all Satellite residents. Because they are separate from the city, they have no idea how much the city has been developing. Yusei has knowledge about machines and computers, so he usually hacks into the security system to watch duel broadcasting. There, people have realized that a duel has developed into a new era called [Riding Duel]. All duelists are riding a vehicle called [D-Wheel] and they are called [D-Wheeler]. In this riding duel, a new rule called [Master Rule] is applied. In order to build up everyone's dream, Yusei assembles a D-Wheel by himself with anything he can gather at Satellite plant, amazing his gang by riding it to summon his ace card, [Stardust Dragon].

The story begins when Jack, who used to be a member of this gang and lived in Satellite with everyone, stole Yusei's D-Wheel and Stardust Dragon card. He rode Yusei's D-Wheel to escape from Satellite through the undersea pipeline linking two cities together. After that, Jack turned pro and became the king of the riding duel, leaving all of his friends behind at Satellite and forgetting his gloomy days over there. In order to follow Jack and get back the precious card, Yusei has to assemble a new vehicle, which is his current [Red D-Wheel]. The gang helps and supports him in order to avoid being arrested by the security at Satellite and escape from this place to go after Jack successfully.


New Power of Stars
In this series, a new of stars called [Synchro Summon] is introduced. There are some conditions required to summon a Synchro Monster, and the main condition is played with the level of stars. One concept is that tuner monster and non-tuner monsters must together be materials for a Synchro Monster. The second concept is that the levels of the material monsters must add up to the level of Synchro Monster to be summoned. This concept is called by Yusei to be a new power of stars. When Yusei is about to do a Synchro Summon, he normally declares to tune a tuner and non-tuner monsters together. The following statement is an example of Yusei's words commonly said in most of his Synchron Summons:

"I tune Speed Warrior with Junk Synchron. Clustering stars will call a new force, become a path its light shines upon. Synchro Summon, come on, Junk Warrior!"

Main Plot of the Story
Like the previous series that must be related to some ancient mysteries, Yu Gi Oh 5D'S doesn't go away from this plot. Although this series comes with new technology in the modern world, the mysteries are related to the ancient era that haven't been solved for thousand years. What is different in Yu Gi Oh 5D'S is that it picks up the mystery of Inca as the main plot of the story. Many artifacts displayed in this series are real and well known to the world. Their origins haven't been resolved, and that is what Yu Gi Oh 5D'S tries to create a main plot. Some people may be familiar with the artifacts in Yu Gi Oh 5D'S that also appear in famous Hollywood movie: Indiana Jones the Kingdom of the Crystal Skull released in May 2008. The difference is that Yu Gi Oh 5D'S main plot isn't with the aliens as shown in the movie but a mysterious dragon called [The Crimson/Red Dragon ~ Akaki Ryu].

The Crimson Dragon (God) VS Nazca Lines (Evil)
As Yu Gi Oh 5D'S has run for a couple episodes, we have been able to find out some figures well known to the world. One of them is [Nazca Lines], mysterious lines in various shapes of animals located in Peru. In our real world, it has been unknown who actually created the lines, and there are variously unique belief about them. A common rumor is that aliens created them, and that is presented in the movie, Indiana Jones the Kingdom of the Crystal Skull. Anyway, how is it related to Yu Gi Oh 5D'S?

The Crimson Dragon	Nazka Lines

Yu Gi Oh 5D'S applies Nazca Lines as representation of gods. They create the story of ancient people 3,000 years ago and call them [People of the Stars]. These ancient people worship the stars as gods called [The Star of Dragon]. Their leader is also called to be [The King of the Star Dragon]. The king has responsibility to pray for the red star in the sky at the top of [Sanctuary of the Sky]. When the red star shines, the king understands that it's a message from the god. He then transfers this message to people. This is the way their civilization has been developed: through the guide of the red star.

Anyway, the world is still disturbed by wicked threats. The king prays for the Star of Dragon for salvation, and the star responds to him again. The star sends the Crimson Dragon, the embodiment of god, to seal the incarnation of an evil left in the earth. This evil has been sealed under Nazca Lines. In reality, there are different hundreds of shapes in Nazca Lines, and most of them are the shapes of animals like birds or lizards. They are the perfect form of a monster that Yu Gi Oh 5D'S tries to present when it is unsealed.

5D'S & Singers
To summon the Crimson Dragon to fight the evil under Nazca Lines isn't easy. Only 5 chosen people called [Signer] with a dragon mark on their bodies can perform this job. The group that has attempted to search for these people is called [Yliaster] leaded by Rex Godwin. Rex is trying to look for the 5 chosen people with a dragon mark. Each mark represents a part of the Crimson Dragon. 4 of them have already been confirmed to have the dragon marks, and they are Yusei Fudo (Tail Birthmark), Jack Atlus (Wing Birthmark), Aki Izayoi, and Ruca (Claw Birthmark). Of course, the dragon actually has nothing to deal with Nazca Lines. It's just the story that Yu Gi Oh 5D'S tries to tie together.

5 Dragons and the 5 Signers should be the theme of this Yu Gi Oh 5D'S series as following:

Signers	Dragon	Dragon Mark's Part
Yusei Fudo	Stardust Dragon	Tail
Jack Atlus	Red Demon's Dragon	Wings
Aki Izayoi	Black Rose Dragon
Ruca	Ancient Fairy Dragon	Claw

In sum, Nazca Lines represent evils sealed in the earth that may be incarnated someday. Only 5 Signers with dragon marks on their bodies can summon the Crimson Dragon to fight the evils. Yliaster currently presented as Neo Domino City's public maintenance bureau is actually the group searching for the 5 Signers.

You may see that the story doesn't seem to be related to Duel Monster games highly advanced in this series. Nevertheless, a duel is still the main battle as usual. Because the story mainly focuses on the power of the stars that ancient people worships, the duel is presented to have connection with the power of the stars. That's Synchro Summon as described earlier.
