To atone for stopping time under the influence, Makoto's sister Akane must undertake a challenging job for the Society. Her mission: retrieve a sacred artifact from a long-sealed chamber in the Tibetan mountains or risk forever staining her reputation. Back in Aomori, Makoto fits a friend in a handmade robe-only to unexpectedly unleash a little chaos. And when a special visitor asks for help, Makoto and her crew put all their skills to the test in a task that, if done wrong, could spell the end of the human race.
