Sanada Yukimura is called the most powerful warrior in history. Oda Nobunaga taught Yukimura about the vastness of the world, Akechi Mitsuhide taught him about the greatness of Nobunaga, and Hashiba Hideyoshi taught him the "taste" of women... but they also taught him about the irreplaceable "youth"...! This is a unique ballad of youth set in the Sengoku period, in which the spirit of Rokubunzen of Sanada in Shinshu runs through the warring world!
