In place of Ratman who cancelled at the last minute, Mana joins Kitaro and the others on their trip. They're headed to an inn exclusive to youkai - the Immortal Onsen. Everyone's getting the most out of the hot springs, but suddenly, the inn is wrapped in an unsettling noise. The source is underground, the riotous energy from Mt. Fuji. Appeasing it is the job of the owner of the inn, but the current proprietress, Nebutori, is so fat she can't always do her work. Mana offers to serve in her place. Mana and Kitaro go into the caves of Mt. Fuji, and a huge shadow closes in on them...!?
Oh, good boys and girls shouldn't do this.
.لا ينبغي للأولاد الطيبين أن يفعلوا هذا
Aber gute Kinder sollten
das nicht nachmachen.
Los niños buenos no deben hacer esto.
Los niños buenos
no deberían hacer esto.
Mais ne faites pas ça chez vous !
Ah, ma i bravi bambini non devono imitarmi!
Ah... Bons meninos e meninas
não deviam fazer isso.
Хорошие мальчики и девочки так не делают.
