This story takes place during the Sengoku period,
during which an inverted social order started to extend all across Japan.

As war rages throughout the Sengoku period,
several influential figures appear across Japan
seeking to reign supreme over these turbulent times.

Among those figures, the great daimyō, Yoshimoto Imagawa,
dispatched his troops to escort the minor daimyo of the neighboring nation –
Ieyasu Tokugawa – as a hostage.
While everyone was assessing the situation,
there was one person watching all of this occur from high above.

That person was Nobunaga Oda.

This story begins with Nobunaga, along with his childhood friend Toshiie Maeda,
as they make a raid on the Imagawa Army in order to rescue Ieyasu.
