From Ponent Mon:
Mountaineer Shiga made a promise to his best friend following his tragic death in the Himalayas. Twelve years later and he is called upon to honor that promise.
When 15 year old high school student, Megumi, fails to arrive home one evening from school her mother calls on her dead husband´s best friend for help. Shiga abandons his refuge in the mountains and descends to the city to look for the girl.
With the police investigation at a standstill, Shiga has to go it alone. But the metropolis can be a much more hostile and dangerous ground than the mountains. What has happened to the youngster and will Shiga find her before it is too late?
