Many centuries ago, the first head of the Kazahana family made this decree: He ordered that the legacy of the Kazahana fortune be sealed, and would only be inherited by a direct descendant of his own blood, 600 years after his death. His word became the law that bound the Kazahana family, and over the ensuing centuries dilligent care resulted in a linear bloodline: with but one male leader for each successive generation of Kazahana. Unfortunately, the carefully pruned family tree went awry thanks to the efforts of a single unsupervised Kazahana, who went abroad and sowed his seeds far and wide.
Now.... It is the 21st century. The number of descendants of the first Kazahana number in the hundreds. With the 600-year old decree to be executed within a year, and with only one possible heir to that legacy.... The Kazahana Family Mass Battle begins! This is one story from the bloody struggles.
