Mark of the Dragon

A Dragon birthmark is a special mark that indicates that a person is a Signer. 3000 years ago, an ancient civilization known as the People of the Stars worshiphed a mystical light called the Dragon Star, which was prayed on by the leader of the People of the Stars, the Star Dragon King, at the top of the Sanctuary of the Sky. When the star shined, the King knew it would be a message from their god, the Crimson Dragon. The dragon was then summoned to imprison an incarnation of an ancient evil in the earth. This evil is represented in the Nazca Lines.

According to legend, the Crimson Dragon could only by summoned with the help of the Signers, whose marks indicated a part of the dragon. These people are being searched for by a group known as Yliaster, led by Rex Godwin, and disguised as the Public Security Maintenance Bureau. Rex Godwin has, as of late, organized a tournament known as the Fortune Cup in order to find the Signers.

Currently, three people have been confirmed to have a Dragon's Birthmark: Yusei Fudo (who has the Tail Birthmark), Jack Atlus (who has the Wings Birthmark), and Aki Izayoi. It is confirmed that Luca has a birthmark as well. It is supposed that Aki and Luca each have a claw.
