The Terrifying Sand Creature

The underground office of the South Pole Unicorn Branch is buried in red sand which suddenly started to gush out in the ice field. As the communications are cut off, Azuma sends Daisaku and Ninami there to see what happened. Before their departure, Marie gives her pendant to Daisaku as a talisman. In the South Pole all the office members are found dead. When two men are gazing at their bodies, red sand starts to flow from the hatch. They soon notice it, but it is too late.
