Elementary schooler Yuuta, who lives next door to Mana, gets the story of Kitaro out of her and goes to the GeGeGe Forest. It's been a few hundred years since the last time a human came to GeGeGe Forest. Kitaro tries to send Yuuta home immediately, but, pressured by the Sand-throwing Hag and Daddy Eyeball, he reluctantly allows Cat-girl to show him around the forest. Yuuta is quite knowledgable about yokai and is overjoyed to see all the different yokai in the forest. Then, suddenly, the forest changes! Kitaro and the others are attacked one by one. Daddy Eyeball says that Yuuta is the cause of it, but...!?
It's like my grandma said.
Yokai really exist!
!كما قالت جدتي، اليوكاي موجودون حقًّا
Yōkai existieren,
genau wie Oma gesagt hat!
¡La abuela tenía razón!
¡Los yokai existen!
¡La abuela tenía razón! ¡Hay yokai!
Mamie avait raison,
les yôkai existent !
È come dice la mia nonnina.
Como minha vó disse!
Yokai existem mesmo!
Бабушка была права. 
Ёкаи существуют!
