Mushishi Zoku Shou 2

Second season of Mushishi Zoku Shou.

Ghostly, primordial beings known as Mushi continue to cause mysterious changes in the lives of humans. The travelling Mushishi, Ginko, persists in trying to set right the strange and unsettling situations he encounters. Time loops, living shadows, and telepathy are among the overt effects of interference from Mushi, but more subtle symptoms that take years to be noticed also rouse Ginko's concern as he passes from village to village.
