SPIRAL BACK Front Cover

Lyric

Spiral stair II

HiiRO

残像の階段 二人の影

Two hearts remain as afterimage

Warp zone 歪む光

声は届かず 私の声だけ反響する

Ghost of prime 沈黙の数

数えながら 未来へ進む

ゼロと無限 交わりながら

消えては戻る 螺旋の軌跡

Fall inward 深く落ち

Rise slow ゆっくり昇る

Möbius breath 途切れぬ誓い

影と影 重なり舞う

And we spiral, spiral back

揺れる螺旋 記憶の残り火

Fragment pulse 時のかけら

Glitchする心拍 ずれる鼓動

Still aligned 揃ったまま

言葉はいらない 残響だけが

光の廊下に 模様を描く

Side by side 触れなくても

Not touching, yet interlaced

Fall inward 深く落ち

Rise slow ゆっくり昇る

Möbius breath 途切れぬ誓い

影と影 重なり舞う

And we spiral, spiral back

ゼロと無限 また巡り会う

Zero meets eternity again

二つの心は 未来を昇る

果てしない螺旋の中で

And we spiral, spiral back

    HiiRO

"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.
