[ENGLISH LYRICS]
Going down into the dark tunnel together
Steadily we travel the long, long path
One year, two years, three, four, five years
You, who used to be behind me, are no longer here

Did you fall down somewhere?
Turn back to look
It's so dark, time passes on and on
All I find are broken fragments of you
I can't hear even one voice

Forever I'm searching for you, who are nowhere to be found
Forever I'm finding pieces of you, who must've disappeared
Forever I'm bound to you, who are nowhere to be found
It's because of you who mustn't be here, it's your fault

Fireworks rise up from the dark tunnel
They flash and sparkle, but the sound doesn't reach me
The light shines like a rainbow
And there's a stranger standing behind me

Ah, I've been found! ah, I've been caught!
Ah, I'm next! ah, it's a demon!
Ah, it was so fun. ah, it must have been funny, you're laughing

In an instant, boom!
A huge roar, crash!
Caving in, the tunnel is crumbling down
Tumble, crumble, crash
In the long in-between, were you enjoying yourself?

I always cared about you, who are nowhere to be found
You who must've disappeared, what were you picking up?
Until death I was bound to you, who are nowhere to be found
It's because of you who mustn't be here, it's your fault

Because of you, I can never, never pass on to the other side
Until my death, that's right, until death I was always bound to you
And it's your fault, not mine!
...eh? it's not my fault! aaah~!
[JAPANESE LYRICS]
暗いトンネルをいっしょに潜る
とても長い道　ずんずん進む
一年、二年、さんよんごねん
うしろにいたきみがいない

どこかで転んだの　探しに戻ろ
とても暗いので時間がかかる
見つかるのは君のかけらばかりで
声ひとつ聞こえない

どこにもいないきみを
いつまでも探してる
消えたはずのきみを
いつまでも拾ってる

どこにもいないきみに
いつまでも縛られる
いないはずのきみのせいだよ
きみのせいで

暗いトンネルに花火があがる
一閃きらめき音は届かない
虹のような光がさして
うしろに知らない大人がひとり
ああ見つかった　ああ見つかっちゃった
ああ次はぼくが　ああ鬼だね
ああ楽しかった　ああ面白かったときみが笑う
瞬間　ドッカン　轟音　ガッシャン　崩壊　トンネル崩れてゆく　ガララ　ガララ　ガララ
長い間ずっと楽しんでたの？

どこにもいないきみを
いつまでも気にしてた
消えたはずのきみの
なにを拾わされてたの

どこにもいないきみに
死ぬまで縛られていた
いないはずのきみの
せいだよきみのせい

ぼくはいつまでも
きみのせいでいつまでも
人生の向こうへたどり着けないまま
ぼくは死ぬまで　そう死ぬまで縛られていた
きみのせいだから　ぼくのせいじゃないよ
えっ　ぼくのせいじゃないよ　あ
