The Children of Ka (A story about Karuta Bot)

The power is within the cards...

Who created these cards and brought about the power within have been lost to time. These cards summoned beings from other worlds to fight for those who held control. Only those that ruled the world held these cards within their grasp, kept under close guard and only used in time of war.

That was until one was dropped within the lands of Ka and discovered by a young man named Ruta.
