Something is causing groups of people to mysteriously age, and each of the victims used a rejuvination cream labelled "Beauty B Beauty." To try to bring the situation under control, Kitaro and the others head to the island where the youkai Nuppeppou is manufacturing the cream. But as soon as they land, they hear a strange song and their bodies begin to age. As they stand there bewildered, the Sand-throwing Hag starts behaving strangely. Though she pretends to know nothing, a jar of "Beauty B Beauty" cream falls out of her sleeve! What is Nuppeppou trying to accomplish? And what will happen to the Sand-throwing Hag...?!
I couldn't believe it. All my friends at
the reunion said I looked younger...
لم أصدق ذلك. كل أصدقائي في لقاء لم الشمل
...قالوا أني كنت أبدو أصغر
Ich konnte es kaum glauben. Meine alten Klassen-
kameraden meinten auch, ich sähe jünger aus.
No puedo creerlo. Mis viejos amigos 
dijeron que había rejuvenecido.
No puedo creerlo. Mis antiguos amigos
dijeron que había rejuvenecido.
Je n’y croyais pas ! Tous mes amis
disent que je parais plus jeune…
Non ci posso credere...
Eu não acreditava! Todas as minhas amigas
disseram que eu parecia mais jovem...
Я не верю своим глазам.
