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...!?
"Backing out"?! This soon before it?
!تلغي؟! قبل موعدها بقليل؟
Nicht mit? Das fällt dir jetzt ein?!
¿Te sales? ¿Justo antes de irnos?
¿Qué? ¿Justo antes de irnos?
Tu décommandes ?
Au dernier moment ?
Hai detto che annulli?! 
Così a ridosso della partenza?
"Interromper"? Logo antes?
Как это понимать?! 
Прямо перед выездом?
