On a warm summer day, a boy heard the sound of bells ringing, as if in celebration, in the mountain near his home. Several years later in that same mountain, the mushishi Ginko stumbles upon a young girl in a mountain with branches and leaves growing out of her body. He later realises that she is the lord of that mountain but finds it strange that a human like her was chosen as the lord. He meets her older brother who has continued to search for her ever since she disappeared while accompanying him on a stormy day. The story is about Ginko’s peculiar journey amidst the occult to unravel the mystery behind the enigmatic girl called Kaya and the mountain that has become her home. NOTE: This was released as a singular episode on the individual disc release, however the Mushi-Shi complete collection discs have this as S02E21 and S02E22.
