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...!?
When things happen between
yokai and humans, I can't leave it alone.
لا يمكنني ترك الأمور بحالها
.عندما تحدث أشياء بين اليوكاي والبشر
Bei Problemen zwischen Yōkai und Menschen
kann ich einfach nicht wegsehen.
Porque no puedo ignorar un 
conflicto entre yokai y humanos.
Porque no puedo dejar pasar
un conflicto entre yokai y humanos.
Je ne peux rester passif si des conflits
éclatent entre humains et esprits.
Quando succede qualcosa tra yōkai ed esseri umani, 
non riesco a rimanere senza fare nulla.
Quando acontecem coisas entre Yokais e
humanos, eu não posso deixar isso de lado.
Я не могу сидеть сложа руки, когда
между людьми и ёкаями что-то случается.
