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.
It makes me start to think about 
where the soul really dwells.
إنّ ذلك يجعلني أفكّر
.في أين تنتمي الرّوح بالفعل
Was bedeutet es, eine Seele zu haben?
Me hace preguntarme
dónde reside realmente el alma.
Me hace preguntarme
dónde reside realmente el alma.
En voyant tout ça, on s’interroge
sur les origines et la nature de l’âme.
A te, questa scena 
non fa sorgere la domanda
Me faz pensar sobre qual seria
o lugar onde realmente fica a alma.
Я вот всегда начинаю думать о том,
что такое душа и откуда она берётся.
