|kan1=
聞こえてくるのは
遠い遠い昔話
|kan2=
忘れてしまっていた
隠されてしまっていた
|kan3=
気に入らないんだと
月の裏へと投げ捨てた
|kan4=
小さくて丸い
ただそれだけの話
|kan5=
聞こえてくるのは
古い古い御伽噺
|kan6=
かつてはあっただろう
優しい日々もそこに
|kan7=
狂うっていたのは
私かはたまた貴方か
|kan8=
どちらでもいいでしょう
救われてしまうなら
|kan9=
心の臓が
僅か音を立てる
|kan10=
「意味はあるの？」
|kan11=
わからないまま消した
|kan12=
一秒後には死んでて
三秒後には腐敗してて
六秒後には生き返って
十秒後にはまた死んでて
四十秒後には叫んでて
二分かかって理解して
三分間だけ後悔して
来世、また会おうだなんて
|kan13=
そんなこと言って
わかっているんでしょう
|kan14=
明日の夢さえ
わかっているんでしょう
|kan15=
一期一会また出会って
三者三様それを認め
六道輪廻巡り巡って
十月十日生まれる命
四面楚歌でも駆け抜けて
二者択一を迫って
三千世界を旅してく
|kan16=
来世、また会おうだなんて
|kan17=
今世、また会えるだなんて
|kan18=
伝えてゆくのは
今の私たち
|kan19=
忘れずに遠く
隠さずに近く
|kan20=
きっとこの先
好きになってゆける
|kan21=
この罪も罰も
古い御伽噺のように

|eng1=
I can hear foklore
Coming from far away
|eng2=
It had been forgotten;
It had been hidden
|eng3=
I didn't like it;
I threw it to the back of the moon
|eng4=
Small and round
It was just a simple story like that
|eng5=
I can hear
Very old fairy tales
|eng6=
There were also once
Friendly days
|eng7=
Was it me, or even you,
who went mad?
|eng8=
It wouldn't matter which
If we would have been saved
|eng9=
The heart
Makes a soft sound
|eng10=
"Is there a meaning?"
|eng11=
Without knowing, I disappeared
|eng12=
After one second, you're dead
After three seconds, you're decaying
After six seconds, you are revived
After ten seconds, you die again
After fourty seconds, you're screaming
It takes 2 minutes to understand
And only 3 minutes to regret
I will see you again in the next life
|eng13=
Saying such a thing
You understand, right?
|eng14=
Even dreaming of tomorow
You understand, right?
|eng15=
Once in a lifetime meeting, we'll meet again
Each has their own way of appreciating it
Going round and round the wheel of life
Life born on the tenth day of the tenth month
I'll keep running through, even when embattled
Even faced with an alternative,
I'll continue to travel the whole world
|eng16=
I will see you again in the next life
|eng17=
I'm glad we finally met again in this life
|eng18=
Us, right now
We'll pass it on
|eng19=
Remember that it's far
While it's frankly quite close
|eng20=
Surely, we can come to like
This destination
|eng21=
This crime and this punishment
Like in an old fairy tale
