Ahead of release, the artist outlined the ideas behind Zutto Emerald and its tone:
Love is wonderful. I’m so glad I finally realized it. Enough to wipe away everything that came before.
I’m honestly amazed that a day has come when I truly want to write lyrics full of hope like this.
That’s the symbolic meaning of an emerald.
The 1/f fluctuation—since water and music are alike, they’re both cold and warm at the same time.
Tomggg arranged the sound to make it feel that way.
It’s a secret that this song continues the story of ‘Kimi wa Snorkel’.
Arranger Tomggg described how the new single connects to an earlier collaboration and the imagery he aimed to evoke:
With ‘Kimi wa Snorkel,’ the music felt like floating and diving underwater. In this new song, ‘Zutto Emerald,’ you can imagine happily floating and swimming around with cute floaties. I hope the music captures the feeling of a pool of happiness and the unique sparkle of emerald, expressing all kinds of light through sound.
Additionally, Pixel artist Nanami Yuki, who created the cover art and music video, spoke about the visuals and mood:
From the moment I first heard it, images of being gently rocked by emerald water and floating softly in space came to mind, sparking a flood of ideas that made creating the illustrations very enjoyable.
It’s a soft, happy song, but with a hint of sadness that makes you want to listen to it again and again. I’m very happy to be involved in the music video. It’s been a wonderful experience!
