Spiral stair

かさなる時

Two primes

二つの心

Side by side

Not touching

触れないまま

∞ breathes between

間に息づく

Step by step

一段ごとの未来

Hidden proof

記憶の証明

Zero meets eternity

ゼロと無限

Slips away

消えては戻る

And we spiral

Spiral back

近づく音

Fading call counting silent primes

沈黙の数を数え

Each beat apart

鼓動外れ

Still aligned

揃ったまま

Fall inward

深く落ち

Rise slow

ゆっくりのぼる

Möbius vow

メビウスの誓い

Loop of desire

巡る渇き

Two shadows dance

影が舞い

And we spiral

Spiral back

"SPIRAL BACK" is a concept album composed as a trilogy that explores the threshold between zero and infinity.

In the first chapter, "Spiral Stair", two hearts stand side by side without touching, ascending the steps toward the future.
The second chapter, "Spiral Stair II", portrays two beings who continue to remain close, even within distortions of afterimages, warps, and glitches.
The final chapter, "Spiral Stair III", unfolds as the very stairway disappears, and consciousness expands into the cosmos while dissolving into molecules and particles. Dark matter, quantum foam, neutrinos, and black holes-images drawn from the frontiers of modern astrophysics-resonate with life and memory, culminating in a chaotic and explosive finale.

As its title suggests, "SPIRAL BACK" is a story of beginnings and endings endlessly intertwined.
Climbing the stair, tracing the spiral, and ultimately dissolving into the universe itself-this album invites listeners to experience that journey through sound.

Artist Profile

  • HiiRO

    I capture subtle shifts in emotion and moments when memories quietly resurface, transforming them into sound, words, and visual expression. In collaboration with AI, my works are rooted in electro-ambient, layering delicate waves of synths, breath-like rhythms, and particles of noise to create worlds that resonate with deep layers of consciousness and feeling. Since 2025, I have been sharing my creations on YouTube and releasing singles and albums through TuneCore Japan. The track 108 reached number 4 on the Apple Music Japan Alternative Music Video chart. I hope my works become a spark that brings new light and resonance to the hearts of those who experience them.
