They are the children of legend. Centuries past, the $DOG Pizza Ninja waved his paw and brought life to his true blood children. Since time immemorial, they have watched over the cryptosphere. Guarding the innocent. They gazed from the shadows. They were unseen, yet could walk among us at will without anyone knowing. They are the 犬忍者. The $DOG Shinobi. With the arrival of the $DOG Ninjas, pretending their supposed claim to be true blood children of the $DOG Pizza Ninja, the Shinobi have been forced to sharpen their swords, tune their guitars, and mask up. They have been forced to act. They will fight to send as many $DOG Ninjas as possible to the fires of Satoshi's wallet. They will prove that they - and they alone - are the rightful legacy of the $DOG Pizza Ninja. (Maximum Number of $DOG Shinobi is limited to 301 inscriptions, including double inscription on 犬忍者 #1)
