Grand Design

The Infinity Circuit is one of the Three Emperors of Yliaster's true goals in Yu-Gi-Oh! 5D's.

It has only been shown during important events concerning Primo, Jakob and Lester. So far this is what its known about it:


 * The circuit forms an infinity symbol.
 * It is is generated by drawing out the power of Ener-D from the Duel Runners of Turbo Duelists, according to Jakob.
 * Due to the intense Turbo Duels due to the World Racing Grand Prix more sections of the circuit have been formed.
 * Jakob claims that the Circuit won´t be fully completed unless they use all the power from the Signers.

Jakob also said that the reason behind using the WRGP is to complete this circuit in order to "unleash the unlimited power they desire". The Yliaster Trio claims that when the circuit is completed, the location of what is apparently their "God" will be revealed to them, and when that happens, New Domino City will be destroyed due to it and the circuit being the same size. However, they think of it as a necessary sacrifice in order to "save the world."
