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!
this world does not need humans after all!
!هذا العالم لا يحتاج البشر في نهاية المطاف
dass diese Welt Menschen nicht braucht.

« Ce monde n’a pas besoin
des humains ! »
che alla fine gli esseri umani
sono superflui, per questo mondo!
Este mundo não precisa de humanos!
миру вообще не нужны люди!
