The track “Ayka” in this album is a remake of a previously released track called “Kaya” (sung by Vocaloid GUMI). Did you have the idea for “Ayka” in mind when you were working on “Kaya”?

“Kaya” has a faint storyline and I thought I could expand on it a little more, but I had no intention of making “Ayka” when I was working on “Kaya.” And it’s not really a continuation of the story, but rather another point of view or the other side of the same coin, so to speak, kind of like my song “Ithna.” I expect my fans will be able to unravel it pretty easily. [Laughs]

The album title appears in the lyrics of “Ayka.”

Yes, it does. I included the phrase after I came up with the album title. I added a side story about finding something new and the way various things happen from there. I asked Marron Bosatsu to arrange it for me. You know what, though, I already had the backing track for “Ayka” since about a year ago, but couldn’t find an opportunity to make a video for the song or put it on an album. I was able to include it on this album at last.
