Yama o mamoru kyodai

In the mountainous region of Koshu, Taikahara, there was an intense power struggle between the prominent families, Tamaki and Kakukura. Facing the steward of Kakukura, Kurokawa Senjiro, was Tamaki Daisaburo, who was skilled with a handgun. Daisaburo had granted protection to the charcoal maker, Miyoshi, safeguarding a few mountains passed down from their ancestors. Daisaburo's elder brother, Iori, who had completed his training in Edo, saved Kakukura's only daughter, Koyumi, on his way back home. However, while Daisaburo rushed to Iori's aid after Koyumi was attacked by Kurokawa and his men, their family home was set ablaze.
