2x67 - Lupin the Third

The mountain country of Kima, hidden away in Tibet, has mountains of treasure! On hearing this, Lupin and company head there. Though they infiltrate as a group of anthropological researchers, they are captured by Kinkaku and Ginkaku, the giants who rule the country, and ordered to fight each other as human playing pieces in a game of killer shogi. Jigen and Goemon are sucked into a gourd full of sulphuric acid. How will they get out of this pinch?!
