Brown Bear Man Asirpa's group relax with the local Ainu and plan to get the tattoed skins while Hijikata and Tsurumi are preoccupied with fighting each other. While talking, they learn that there is a reward for catching a legendary wankamuy, a bear that has killed someone. While out hunting, Sugimoto and Asirpa save the man called Heita who then tells them the best method to search for gold, but also that he has made more money from panning for "white", specks of platinum worth as much as gold. It is slowly revealed that Heita panned for gold with the Ainu and that he became both obsessed and terrified by the wankamuy legend. He wore a bear skin when he murdered members of his family and ended up in prison where he was tattooed. When Asirpa and Sugimoto discover that he has a bear skin, he attacks them with uncontrolled ferocity, and is only stopped when he is accidentally shot dead by the poisoned arrow from a deer trap.
