History
During feudal Japan of Second Earth, a Makkine vessel arrived and crashed on the planet. Though damaged the machines used their influence to manipulate the Shogun of Edo, to become their thrall to use the Keystone, a powerful sentient crystal to open a dimensional doorway into Second Earth. However before the plan could be carried out, Miyamoto Usagi a ronin warrior suspecting that his lord's malicious intent intervened and defeated the Shogu piercing the lord of the city with his sword and also the Keystone. In doing so the invasion was prevented and also caused all the Yokai in Japan to be trapped within the Keystone.

The shard of the Keystone that was broken was kept by Miyamoto Usagi as a souvenir. However the samurai for his role in attacking the Shogun, he was labeled as a traitor. A thousand years passed when the Yokai in the Keystone were released by accident at the hands of the samurai's descendant Yuichi Usagi. Not only were all the Yokai free but also the Shogun, who was transformed into a Yokai and still under the enslavement of his alien masters.

Driven by revenge and also his master the Shogun now under the name Kagehito was driven to find the Clavis of the Makkine from their vessel. The Clavis was a device that would force a portal to be opened to the Makkine dimension when combined with the Keystone.

After Kagehito united the two together, he was freed by the Makkine's influence and joined forces with his ancient enemy's descendant to stop them. The Makkine and their horrors were released unto New Edo. It was only through reuniting the Keystone's shard with the greater whole that the Makkine invasion was thwarted thanks to the Yokai Hunters. Unknown to the Yokai Hunters a few Makkine escaped destruction and fled into the sewers of the city.

Culture
The Makkine are the oldest beings in all the many dimensions of the Multiverse. They are machines that exist only to conquer all worlds and steal resources and enslave other races. Those that resist are eliminated.
