Alongside the trailer, the website shared a comment from Vaundy, who explained the inspiration behind the track.
“I had the opportunity to write the opening theme song ‘Saikai’ for The Summer Hikaru Died.
When I read the original manga, I felt a constant sense of unease, never knowing what would happen on the next page—
I turned that feeling directly into this song.
I hope it’s a piece that also takes on the challenge of pushing anime music forward.
If you could meet someone again, who would you want to see?

Mokumokuren first conceived of the series while studying for exams and later began posting drawings on Twitter, which led to the Young Ace Up editorial department approaching Mokumokuren to serialize the manga via the Young Ace Up website.
