「いつか必ず私を迎えに来て欲しい」
「誓おう　この命に換えても」
| kan2          =
弱く儚い約束　直向きな命
人の子の運命見つめていよう
決して結ばれることは無いとしても
ただ祈り続けていたい
| kan3          =
金と銀で作られた偽りの樹にも
春来たりなば　真珠の花が
誓いの箱舟よ　月に届くまで
千代に八千代に宇宙を駆けろ
| kan4          =
いつか此処まで迎えに来てくれたのなら
その時は伝えたいことがあるの
いつか誓いを果たして　この身が朽ちても
振り返る者もなく
| kan5          =
“人の作りし星が　夜空で手をつなぎ
やがて光の綱が　地上を包み込む
あらゆる境界を　するりとくぐり抜け
誰しもの想いが　実を結んでゆく”
| kan6          =
僅か百年の仲で　消え行く命　慈しむことも嘆くことも
それは百年の過客　残された言葉　ただ只管に想う
| kan7          =
“今や機械の腕が　人々を支えている
たとえ言葉が消え　文字さえも無くなり
時を経てもなお　　愛がそこに在るなら
| kan8          =
私は　生きよう”
| kan9          =
誓おう　この声を月に届けよう
千代に花開く想い　高らかに
狂おしく満月　片時も離れずに
羽衣は永久の夢

“I want you to come for me someday…”
“I swear it! Even if I forfeit my life in exchange.”
| eng2          =
A weak, fleeting promise. A single-minded life.
I shall stare at the children’s fates.
Even if we will never be linked,
I want to keep praying.
| eng3          =
When spring arrives, pearl flowers will bloom 
even upon a false tree made of gold and silver.
O ark of oaths! Until you reach the moon,
Race through space for millennia and millennia.
| eng4          =
If you will come to receive me someday,
There’s something I want to say then.
Though my body may rot when my oath is fulfilled,
There is not a soul who will look back.
| eng5          =
　“Manmade stars link hands in the night sky.
　　　Eventually, the rope of light will envelop the surface.
　　　Slipping through all boundaries,
　　　Everyone’s wishes will bear fruit.”
| eng6          =
Lives fade away after a mere century. Loving… grieving…
They are the words left behind by the century travellers. I just feel for them earnestly.
| eng7          =
“Now, mechanical arms support humans.
　　If language fades away and even letters vanish,
　　Though time may pass, love will still remain there. If so…
| eng8          =
　　…I will live.”
| eng9          =
I shall swear an oath! My voice will reach the moon!
My feelings blossom over the ages, reaching up high.
Without parting from the maddening full moon for a moment,
The angel’s raiment is an eternal dream…
