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...!?
Still, I wish I could
go to some hot springs, too.
.رغم ذلك، أردت أن أذهب إلى الينابيع الساخنة حقًا
Trotzdem würde ich gern auch
mal wieder zu ’nem Onsen.
Pero también quisiera ir
 a las aguas termales.
Pero yo también quiero
ir a los baños termales.
Je dis ça, mais j’aurais bien voulu
aller aux sources chaudes.
Però avrei voluto andarci anch'io alle terme...
Mesmo assim, eu gostaria de
ir para umas águas termais.
И всё-таки я тоже хотела бы 
на горячие источники.
