Saichi Sugimoto

Saichi Sugimoto is a battle-hardened survivor whose extraordinary resilience on the Russo-Japanese War's frontlines earned him an almost mythical reputation. Driven by a solemn promise to his fallen comrade and the desperate need to fund medical treatment for the man's ailing wife, he ventures into the unforgiving wilderness of Hokkaido in search of gold. Upon learning of a vast fortune secretly amassed by the Ainu people, he forges an unlikely alliance with the skilled young Ainu girl Asirpa, and together they plunge into a perilous, multi-faction race to decode a map tattooed across the skin of escaped convicts.
