Yasuno Sakai

Teenage cousins Masao and Tamiko fall in love when she comes to his riverside brewery house to take care of his sickly mother. Family objections ensue as Tamiko is older than Masao, and the two cannot marry in peace.

With most of his family already dead at Ogami Itto's hands, Retsudo launches one final plot to destroy him, and when that fails, unleashes the fury of every remaining member of the Yagyu clan.
