Heiji Koito is a Rear Admiral of the Imperial Japanese Army.

In the early twentieth century, Russo-Japanese War veteran Saichi “Immortal” Sugimoto scratches out a meager existence during the postwar gold rush in the wilderness of Hokkaido. When he stumbles across a map to a fortune in hidden Ainu gold, he sets off on a treacherous quest to find it. But Sugimoto is not the only interested party, and everyone who knows about the gold will kill to possess it! Faced with the harsh conditions of the northern wilderness, ruthless criminals and rogue Japanese soldiers, Sugimoto will need all his skills and luck—and the help of an Ainu girl named Asirpa—to survive.

But Sugimoto is determined to find and protect Asirpa! Along the way, he’ll discover new people, new cultures rich with history, and an unforgiving terrain. Will Sugimoto and Asirpa survive their journeys and reunite?

The high-stakes search for gold continues in the harsh wilderness of Hokkaido! More and more people seek the treasure map, and the race to find its living pieces is brutal as all get-out. War veteran Sugimoto and his guide to the wilds, Asirpa, are hot on the trail, and as long as they stick together through thick and thin—chitatap and miso—they’ve got a shot at finding that gold.
