After hearing that children are going missing all over, Mana contacts Kitaro and the others and is ready to go with them to discover the truth behind the incidents, but Kitaro turns her down, saying that humans and youkai can't be friends. It's soon clear that a yokai that had once been sealed away is taking children to build a yokai castle. Then, Mana is abducted. Kitaro goes to rescue Mana with the Sand-throwing Hag and the Child's-cry Old Man!
It's a castle they built
deep in the mountains a long time ago.
إنّها قلعة بنوها في أعماق
.الجبال قبل وقت طويل
Ein Schloss, dass sie vor langer Zeit
in den Bergen gebaut haben.
Es un castillo
que construyeron en una montaña.
É um castelo que eles construíram
encravado nas montanhas há muito tempo.
Его давным-давно
 построили глубоко в горах.
