As the seasons turn, Rimuru plans a Bon Festival celebration.

Seeing my pupils mature is 
both joyful and saddening.
رؤية تلاميذي ينضجون مُفرِحة ومُحزِنة في نفس الوقت

La evolución de un discípulo
alegra y entristece por igual.
Les progrès d’un élève sont source

Рост ученика отдаётся в сердце
и радостью, и щемящей грустью.
