The year is 20XX. The ninja, who once forged the history of Japan, were scattered across the country during the Meiji Restoration.

The descendants of these ninja clans, seeking to preserve their heritage, formed the WNA (World Ninja Association) in the hope of carrying on their legacy. And so it was that the WNA succeeded in developing Ninja-Gum, an art which could summon forth the strength of the Shinobi.

The second half of the second season of Cardfight!! Vanguard G series.

Nadie is a bounty hunter with an attitude, and she's got a lock on her next target: Ellis, a young amnesiac girl who is a suspect in the murder of a famous scientist. Nadie manages to apprehend Ellis, but on a whim, decides to accompany her to Wiñay Marka, a place which supposedly holds the key to unlocking Ellis's memories and her mysterious past. However, Nadie cautions Ellis that this does not mean she will go free—once Ellis has found what she is looking for, Nadie will turn her over to the authorities. With Ellis's connection to a gemstone called the Inca Rose as their only guide, the two set off on their journey south through Mexico to search for the mysterious "Eternal City" of Wiñay Marka.
