Evan Call's comments for Kairyu and the Mailman:
I have loved Pokémon since I was a child, collecting cards, enjoying the games, and watching the anime. I was really happy when I heard about this project and was surprised because I had just played Pokémon Scarlet last year and had previously watched the Pokémon anime.

When I was told the theme of this project, I felt that it naturally overlapped with the feel of my music, so I immediately started writing the music. The principles of "friendship and mutual help", which I feel is a major theme of Pokémon, is beautifully depicted in "Kairyu and the Mailman", and I feel it especially strongly with the theme song sung by suis. I put my heart into the music while being conscious of the dynamics of adventure, and I am forever proud to be a part of the work.
