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.
That tough subject all 
of us face sooner or later.
ذلك الموضوع الصّعب الّذي
.نواجهه جميعًا عاجلاً أم آجلاً
Ein Problem, dem wir uns
alle stellen müssen.
Por eso que debemos asumir
tarde o temprano.
Por eso que debemos asumir
tarde o temprano.
Celui auquel
on est tous confrontés un jour.
La questione spinosa che tutti noi
dobbiamo affrontare, prima o poi.
Aquele assunto que, uma hora,
todos temos que encarar.
О том, с чем нам, увы,
однажды приходится сталкиваться.
