Mana has gone camping with Souma, Hiroto, Yuuta, and their father Yuuichi. Though Souma and Hiroto's horseplay is exasperating, Mana enjoys her holiday. But that night, Yuuichi suddenly disappears. When Souma and Hiroto go looking for him, they are attacked and kidnapped. As an eerie laugh echoes through the space, Mana and Yuuta wonder if it might be the work of a youkai. They hurry to tell Kitaro, but...!?
The door to the unseen world opens...
...يفتح الباب إلى العالم غير المرئي
Das Tor zur verborgenen Welt öffnet sich.
Se abre la puerta
hacia el mundo invisible.
Se abre la puerta
hacia el mundo invisible.
Une porte s’ouvre
sur un monde invisible…
Si apre la porta del mondo invisibile.
A porta para um mundo invisível se abre.
Дверь в невидимый мир открылась...
