In the turbulent streets of 1863 Kyoto, during the waning days of the shogunate, young orphan Nio dreams of a better world despite the chaos and bloodshed surrounding him.

Inspired by their resolve, Nio joins their ranks, determined to carve a path toward justice in a time of political upheaval and clashing ideals. (Unreviewed summary by Grok 2)
