Golden Kamuy: Abashiri Prison Assault Arc

Former soldier Saichi Sugimoto, nicknamed "Immortal Sugimoto," learns of a clue to a vast stash of Ainu gold stolen by a mysterious man named Noppera-bo, who, before his capture, scattered the location of the hidden gold across the bodies of multiple prisoners. Asirpa, informed by Chirolanke that the gold thief might be her late father, Wilk, sets out with Sugimoto to uncover the truth about her father and the gold's whereabouts, heading to Abashiri Prison where Noppera-bo is held. Lieutenant Tsurumi's Seventh Division and Toshizo Hijikata's remnants of the former shogunate also target the prison. Amidst the heavily guarded prison holding seven hundred hardened criminals, three factions converge, igniting a chaotic battle over gold and truth.
