Golden Kamuy

Around a campfire, Shiraishi tells Toshizō Hijikata, Nagakura Shinpachi, Inkarmat and Kiroranke, of his time in Kabato Prison when he met Chouan Kumagishi, a master forger. Shiraishi asked him to draw a shunga for him which he kept for company, but Kumagishi drew the face of a nun who visited prisoners called Sister Miyazawa. Shiraishi thought the picture was badly drawn, a round face with tiny features, but after a while he fell in love with her and decided to escape and meet her.
