《Artist Comments》
Hello, this is Punipuni Denki.
This time, I am very happy to provide the theme song for “Koala Picture Diary” by writing “Rainbow to”.
I cried many times after reading the work, but by inviting Kan Sano as an arrangement, the heartfelt sadness I received from Yuami-sensei’s original work is tightly packed into the lyrics and soft synths.
Please enjoy it together with the anime.
