A traveler named Ginko who is known as a Mushi Master, searches for a boy who it is claimed to have the ability to create life with calligraphy drawing by the help of a spiritual matter known as Mushi.
Ginko investigates accident of the mountain with Ko-myaku channnel. He hears from inhabitants that Mujika, who is an old mushishi, lives in the mountain.
Driven to seek shelter from a snowy storm, the Mushi Master Ginko is drawn into a yearly mystery. A lone boy wanders off into the forest during the harshest part of every winter, only to be later found asleep and clutching spring's blessings in his grasp.
A servant with high aspirations reaches up and disappears into the sky. For a time she resides in the shadow world of the mushi. Found by Ginko,he explains to her suitor she is now linked to both worlds.
Rumors of a new kind of mushi have brought Ginko out to visit another master, one who's been studying the discovery for some time. But upon his arrival, Ginko is disturbed to find the villagers preparing to destroy the mushi.
