|kan1=
いつかこの世界のどこかで
隣り合う螺旋の夢
|kan2=
失くした瞳を探す黒い旅人
見えなくなった星空を探り当てるように
|kan3=
見えない闇へと手を伸ばす
|kan4=
もしもこの世界のどこかで
もう一度出会えるなら
何度でも繰り返そう
忘れ得ぬ螺旋の夢を
|kan5=
見えない心を探す黒い旅人
忘れてしまった何かを掴み取れるように
|kan6=
消え行く光へ手を伸ばす
|kan7=
もしもこの世界のどこかに
隠されたドアがあれば
暴き出し夜を駆ける
あの頃の"僕ら"は"二人"で
|kan8=
いつもいつまでも続いてく
現実を繰り返して
また{{alt-ja|幻想|ユメ}}で出会えるなら
もう一度螺旋の夢を
|kan9=
落ちていく落ちていく
眠りへと堕ちていく
|kan10=
どこまでもどこまでも
戻れない深遠に
|kan11=
何度でも何度でも
届くまで手を伸ばし
|kan12=
大切な片割れを
もう二度と離さないように
二人で
|kan13=
見つけたうつつのゆめを繋ぐ旅人
互いの二つの欠片を混ぜ合わせるように
|kan14=
掴んだその手を離さない
|kan15=
いつかこの世界のどこかに
隠されたドアを開けて
君とまた夜を駆ける
いつまでも"僕ら"は"二人"で
|kan16=
もしもこの世界が滅びて
二人また引き裂いても
何度でも見つけるから
その日まで螺旋の夢をa

|eng1=
Someday, somewhere in this world,
A spiraling dream of us sitting side by side…
|eng2=
As if a black dressed traveler searching for his lost eyes
Finds out about the starry night’s sky he couldn’t see…
|eng3=
Reaching out his hand towards the unseen darkness…
|eng4=
If I could meet you one more time
Somewhere inside this world,
I’ll repeat it infinitely,
That unforgettable spiraling dream…
|eng5=
As if a black dressed traveler searching for his invisible heart
Grasps something he ended up forgetting…
|eng6=
Reaching out his hand towards a vanishing light…
|eng7=
If somewhere inside this world
There lies a concealed door,
I’d open it and haste towards the night.
I want to continue to be “us”,
|eng8=
,The “two of us” from that time, forever,
Always repeating our reality;
If we could meet up inside an illusory dream,
I want it to be that spiraling dream again…
|eng9=
Falling down, falling down,
Ascending into a sleep;
|eng10=
Anywhere, anywhere,
Towards an abyss from where I can’t return;
|eng11=
I’ll outstretch my hand for any number of times,
Until it will reach you;
|eng12=
In order not to part again
From my precious counterpart…
We, together…
|eng13=
As if a traveler who found a reality and his own dreams
Would connect each other the two fragments together…
|eng14=
…Don’t let go of the hand you’re holding.
|eng15=
If someday we’ll open that concealed door
Hiding somewhere inside this world,
I’d haste towards the night again, with you,
Because that “we” means “the two of us”.
|eng16=
Even if this world would perish,
Even if we’ll be separated again…
Let’s keep having that spiraling dream again
Until the day I’ll find you again.
