There is a school for ghosts and monsters. There, there are no tests or anything else. As this rumor spreads, Yuuto comes to Mana with a story about his friend saying he will become a ghost, then disappearing. Kitaro has received a lot of letters about exactly the same thing. Apparently, if you speak an incantation at the graveyard on Third Street, Fourth Street, which shouldn't exist, appears and you can go to the ghost school. In the middle of the night, Kitaro goes to try the incantation, and another dimension appears before his eyes. As he advances deeper into the space, he finds a school where children seem to be happily taking classes. The teachers there are yokai Kitaro had already defeated. Bewildered, Kitaro becomes one of the students in order to keep an eye on things.
More importantly, how did Tantanbo
and the others come back?
الأهم من ذلك، كيف عاد
تانتانبو والبقيّة؟
Aber sag mal, wieso sind Tantanbō
und die anderen zurückgekommen?
Pero ¿cómo es que Tantanbo
 y los demás volvieron?
Pero ¿cómo es que Tantanbo
y los demás volvieron?
Bon, pourquoi Tantanbô
et les autres sont de retour ?
Piuttosto, perché Tantanbō
 e gli altri sono resuscitati?
Mudando de assunto, como
Tantanbo e os outros voltaram?
Скажи лучше, как Тантанбо 
с остальными вернулся?
