Buchio grapples with a concern that all yokai like him eventually face: the fact that his lifespan is much longer than that of humans. His new friend Wagen has been dealing with the same concern in his life with his aging partner, Kazuhiko.
When I think about my 
family dying before me,
،عندما أفكّر في أنّ عائلتي ستموت قبلي
Cuando pienso en que mi familia
morirá antes que yo…
Cuando pienso en que mi familia
morirá antes que yo…
Quand j’ai pensé au fait
que ma famille mourrait avant moi,
Se penso che il resto della mia famiglia
morirà prima di me,
Quando penso na minha família
morrendo antes de mim,
Когда представляю, что все члены семьи
умрут раньше меня,
