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!
So long as the Yokai Castle exists,
we are invincible!
طالما كانت قلعة اليوكاي 
!موجودة، فنحن خارقون
Solange das Yōkai-Schloss existiert,
sind wir unverwundbar.
¡Mientras tengamos el castillo yokai,
somos invencibles!
Tant que nous avons le château yôkai,
nous sommes invincibles !
Finché esisterà questo castello yōkai,
Enquanto o Castelo Yokai
existir, somos invencíveis!
Пока стоит замок ёкаев,
нас не одолеть!
