Gekido no 1750 Nichi plot
After the leader of the powerful Kamioka family dies, a suitable successor must be appointed. During the general members' meeting, interim leader Kawakatsu is put forward as successor by the older generation. However, the younger generation, led by Wakatake, would like to see Tokitsu as his successor, who is currently in prison for tax fraud. The widow of the deceased leader expresses her preference for Tokitsu, but the old guard refuses to give in. Tokitsu then threatens to secede from the Kamioka family if Kawakatsu is elected leader. A definitive division develops when Kawakatsu separates from the Kamioka family under the name of Hachiyakai. A bloody battle ensues between the rival groups.
