Ex-convict Keiji Ueji appears in Sapporo, causing all the different factions to travel to the city in hopes of obtaining part of the map to the Ainu gold that is tattooed on his skin. At the same time, a figure who appears to be a copycat of Jack the Ripper terrorizes the streets of Sapporo. Saichi Sugimoto, Asirpa, and Yoshitake Shiraishi—joined by Fusatarou "Boutarou the Pirate" Oosawa and Vasily Pavlichenko—temporarily ally themselves with Toshizou Hijikata, as his faction's motives are somewhat less disturbing than those of Seventh Division's First Lieutenant Tokushirou Tsurumi.
Asirpa tries to gather all the necessary information to distinguish the fake furs from the real ones, but she is unable to decipher the map with certainty. Sugimoto vows never to abandon Asirpa, but the turmoil surrounding the serial killer leads to new betrayals, and Tsurumi’s plan to capture Asirpa moves forward. As the search for gold nears its conclusion, the future of the Ainu depends on who will be the first to seize it.
