Trivia, insights & behind the scenes
The Ainu language and customs are portrayed with unprecedented accuracy for anime—actual Ainu consultants were involved, and the manga author lived with Ainu communities for research.
Sugimoto is loosely based on real Russo-Japanese War veteran Saichi Sugimoto, who supposedly survived multiple death-defying wounds that earned him the nickname 'Immortal.'
