Queste le sue parole:

"Tamashii No Houkai is co-written by Ihsahn — the legend behind Emperor and a musician who has been a longtime influence and mentor to so much that I do in music. The writing of this song was the turning point for Ibaraki — it summarized everything from the past, present, and future of what I thought black metal was, is, and could be."
