Race is the 19th chapter of the Golden Kamuy manga.
Sugimoto is being transported to the hospital by Tsurumi's order, but it turned out to be a plan to escape. Tsurumi discovers Sugimoto's plan and pursues him, but is intercepted by Asirpa who stops him by injuring the horse with an arrow. Tsurumi gets back to the base and it on fire but he isn't worried as he wore the tattoed skins like a coat. In the end Sugimoto and Asirpa meet again.
