A forest has appeared in Shibuya's scramble crossing. People in the city are inexplicably turning into trees. Only half believing, middle schooler Mana puts a letter in the Yokai Post, and with a clip-clop GeGeGe no Kitaro appears! After hearing Mana's story, Kitaro and Daddy Eyeball are convinced it's the work of a youkai who was sealed away a few hundred years ago. In order to discover the origin of the phenomenon, Kitaro and Mana head to an underground facility in the city where something lies in wait for them...!?
They're drawn to the darkness
in people's hearts.
إنّهم ينجذبون إلى الظلام 
.الذي في داخل قلوب البشر
Die Dunkelheit in den Herzen
der Menschen zieht sie an.
Los atrae la oscuridad
de los corazones humanos.
Los atrae la oscuridad
de los corazones humanos.
Ils sont attirés par les ténèbres
dans le cœur des gens.
Sono affascinati dalle tenebre dell'animo umano.
Eles são atraídos pela escuridão
no coração das pessoas.
Они тянутся ко тьме в сердцах людей.
