HOTARUBI NO MORIE Japanese version manga

The original Hotarubi no Mori e shōjo manga^[2] and subsequent film tell the story of a six-year-old girl named Hotaru Takegawa, who gets lost in a forest inhabited by a mountain spirit, as well as yōkai (strange apparitions from Japanese folklore). She is found by a mask-wearing, human-like entity named Gin, who informs Hotaru that he will disappear forever if he is touched by a human. Gin then leads Hotaru out of the forest. Hotaru returns to visit Gin in the forest over the next few days and they become friends despite the limitations on their interactions. Although at summer’s end she must leave Gin to return to the city and her studies, Hotaru promises to return to visit him every summer holiday.
