The quest for the lost Ainu treasure is escalating, with intimidating ex-convicts fiercely guarding their tattoos. Saichi "The Immortal" Sugimoto and Asirpa have teamed up, but Asirpa's encounters with Kiroranke and Ogata Hyakunosuke have impacted her goals and strengthened her resolve. As they leave Russian territory, an unusual member joins them. Meanwhile, Toshizou Hijikata's crew struggles to acquire prized skins and falls into a deadly trap set by a dangerous fugitive. Though each group has advantages, not even the ruthless First Lieutenant Tokushirou Tsurumi can advance without Asirpa's help. Yet, his true intentions for their inevitable encounter remain a mystery.
