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!
They're truly one with the castle!
!إنّهم واحدٌ مع القلعة بحق
Sind sie etwa wirklich eins
mit dem Schloss geworden?
¿Acaso son parte del propio castillo?
Con il castello formano proprio un'anima e un corpo?!
Eles estão mesmo unidos com o castelo!
Они на самом деле едины с замком!
