Ninjala

World Ninja Association wanted to prevent the Hertage of Ninja. After the Meiji restoration,  Ninja left Japan and spread all over the world and slowly forgot their history. They get merged with other clans and in this way, their bloodline gets thinner with time. WNA wanted to protect them for they designed a Ninja-Guum which is made from Ninja Pure DNA. To gather all the ninjas together and collect blood from them they organized a Ninjala Tournament.
