深い 深い slow descent
どこまで行ける? — no intent
ただ流れる breath and sound
沈むだけ underground
水が揺らぐ echoes stay
光消えて fade away
どれほど奥に truth remains
I’m chasing shadows in my veins
ざわざわ ざわめく skin inside
心の奥で waves collide
名前のない その感覚
Whispers hidden, can’t deny
降りていく deeper, deeper
Beat の底で sleeper sleeper
誰も触れない black horizon
Inside my fall, I find my reason
雫は落ちて count the time
砕ける silence, breaking rhyme
夢の残像 重なり合う
Fragments glow, but never shine
ゆらり揺れる sway of night
I flow with darkness, out of sight
どこまで行ける? limit unknown
Every drop is mine alone
降りていく deeper, deeper
Beat の底で sleeper sleeper
No command, just gravity’s hand
In the endless dive, I understand
深くには何があるの?
あるのは pile of masks I saw
仮面の山 積もる silence
すべての顔が ここにあるの?
Broken smiles, forgotten names
Roles we played, all the same
ただの影 ただの皮膚
Left behind, nothing to claim
降りていく deeper, deeper
Beat の底で sleeper sleeper
No command, just gravity’s hand
In the endless dive, I understand

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. - HiiROの他のリリース
