This is the only time Jun Senoue and Tomoya Ohtani have worked together on a song, and I wish it happened more often because it's so good.
Technically Jun Senoue has contributed his guitar playing skills for some of Tomoya Ohtani's other songs (the music for Infinite in Forces is a good example), and they've also arranged songs by each other, but this is the only time they've been credited as having both composed and arranged a song.
