Having received a letter saying "We are being attacked by the youkai Mannendake," Kitaro travels to a bamboo grove deep in the mountains. The owners of the bamboo grove, a married couple, Masahiko and Kiyomi, Kubota from the tourism association, and Ratman are waiting for him. They wanted to turn the bamboo grove into a tourist spot, but they say that the former owner of the grove, Daikichi, as well as others, have gone missing. As soon as Kitaro steps foot in the grove, he senses youkai energy. A warning to humans is written in blood in the grove, but the study in Daikichi's mansion within the grove is full of bamboo leaves... Suddenly, Masahiko falls silent. When they turn to look, Masahiko has been turned to bamboo...!?
Kitaro, we'll have to find
where the Mannen-Dake itself is.

.مكان مانّين-داكي الحقيقي
Kitaro, tendremos que encontrar 
al Mannen-Dake original.
Kitaro, tendremos que encontrar
al Mannen-Dake original.
Kitarô, on doit trouver
le Bambou millénaire.
Kitarō, a questo punto credo che dovremmo cercare 
dove si trova il vero corpo di Mannendake.
Kitaro, temos que encontrar
onde o Mannen-Dake está.
Китаро, нам надо выяснить, 
где находится сам Маннэн-дакэ.
