|kan1=
何のために在るのだろう感情などはとうに腐って
のろわれた水に沈んだ呼ぶ鳥は遥か遠くて
|kan2=
兆しすら無いままに叫んだとて虚しくなるだけ
何度でも夢に見る光なんてまぼろしでしょ
|kan3=
行く宛の無い旅路　暗闇の中一人
救われるはずもない　永遠にこの海に
足る事を知らぬまま　愚かに歩を進める
いつまで続けるのか　会えるその日まで
|kan4=
在りたくて在るわけじゃない
滅び方すら分からないだけ
輪廻に戻れるのなら
塵と消えてもかまわない
|kan5=
この海に縛られて忌み嫌われてすべてを亡くした
未練など無いはずの瞳から涙　こぼれ落ちた
|kan6=
行く宛の無い旅路　暗闇の中一人
救われるはずもない　永遠にこの海に
足る事を知らぬまま　愚かに歩を進める
何時まで続けるのか　会えるその日まで
|kan7=
答えが見えなくても　いずれたどり着くはず
絶望の底にある　ひとひらの祈り
足る事を知らぬまま　愚かに歩を進める
何時まで続けるのか　会えるその日まで
終わるその日まで　還るその日まで 

|rom1=
nan no tame ni aru no darou kanjou nado wa tou ni kusatte
norowareta mizu ni shizunda yobu tori wa haruka tookute
|rom2=
kizashisuranai mama ni sakenda tote munashiku naru dake
nando demo yume ni miru hikari nante maboroshi desho
|rom3=
yuku ate no nai tabiji kurayami no naka hitori
sukuwareru hazu mo nai towa ni kono umi ni
tarugoto wo shiranu mama oroka ni ho wo susumeru
itsumade tsuzukeru no ka aeru sono hi made
|rom4=
aritakute aru wake janai
horobi kata sura wakaranai dake
rinne ni modoreru no nara
chiri to kiete mo kamawanai
|rom5=
kono umi ni shibararete imikirawarete subete wo nakushita
miren nado nai hazu no me kara namida kobore ochita
|rom6=
yuku ate no nai tabiji kurayami no naka hitori
sukuwareru hazu mo nai towa ni kono umi ni
tarugoto wo shiranu mama oroka ni ho wo susumeru
itsumade tsuzukeru no ka aeru sono hi made
|rom7=
kotae ga mienakute mo izure tadori tsuku hazu
zetsubou no soko ni aru hitohira no inori
tarugoto wo shiranu mama oroka ni ho wo susumeru
itsumade tsuzukeru no ka aeru sono hi made
owaru sono hi made ka eru sono hi made

|eng1=
Why do I still have them, I wonder, my emotions have been eroding since long ago
Sunken in accursed water, the calling birds sound far, far away
|eng2=
Even if I shout, my cries just die out without a sign
However many times I see the light in my dream, it's just an illusion
|eng3=
Without expecting to be saved, forever in this sea
I journey without a destination, alone in the darkness
Not knowing how far I must go, I keep striding blindly ahead
How far must I walk until the day I can meet you?
|eng4=
Because I long for it, it will never be; 
the only thing I need to know is how to perish
If I can return to the cycle of rebirth
I don't care if I fade to dust
|eng5=
Bound to this sea, hated by all that is pure, I've lost everything
And though I should have no lingering regrets, tears spill from my eyes.
|eng6=
Without expecting to be saved, forever in this sea
I journey without a destination, alone in the darkness
Not knowing how far I must go, I keep striding blindly ahead
How far must I walk until the day I can meet you?
|eng7=
Even if I can't see the answer, I should reach it eventually
The petals of my prayers lie at the bottom of my despair
Not knowing how far I must go, I keep striding blindly ahead
How far must I walk until the day I can meet you?
Until the day it all ends? Until the day I leave?
