The pursuit of the vanished Ainu gold reaches its climax, as increasingly powerful former inmates strive to protect their scarred skins. Saichi "The Immortal" Sugimoto and Asirpa can finally progress together, yet Asirpa"s time with Kiroranke and Ogata Hyakunosuke has modestly shifted her goals and bolstered her resolve. When their group departs the vast Russian territory, they acquire an odd companion.
At the same time, Toshizou Hijikata"s squad advances aggressively to secure priceless skins, falling into a lethal snare set by a perilous felon. Though each faction holds a distinct edge, even First Lieutenant Tokushirou Tsurumi—the fiercest and cruelest rival—cannot move forward without Asirpa"s aid, despite the shadows that loom over them. Yet his sinister schemes for their inevitable encounter remain unknown.
