Yahiro is a ninja navigating a war-torn world where the northern and southern continents clash for dominance. His singular focus is finding the three stolen mystical Jingi artifacts, driven purely by the desire to sell them for personal profit, not to influence the political struggle or resolve the Yamato Empire's succession crisis ignited by their theft. This mercenary goal fuels his journey. He faces perilous encounters with assassins and interacts with figures like princesses, who present significant obstacles and complications along the way. His quest unfolds against the backdrop of the intense conflict over the Jingi, artifacts crucial for determining the next sole ruler of Yamato.
