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.
So now that we're friends, 
why don't we speak more casually?
لماذا لا نتحدّث بشكل أقلّ رسميّة
بما أنّنا صديقان الآن؟
Dans ce cas, ça ne vous dirait pas
de passer au tutoiement ?
Allora che ne dici
di mettere da parte tutte le formalità?
Então, sendo amigos, que tal conversarmos
de maneira menos formal?
Раз так, то, может,
и общаться будем более по-дружески?
