|kan1=
まわりまわる　世界の中
独りきりを感じた
共に過ごす人にも　別れは来る
|kan2=
ポジティブさが　足りないなら
走りだせばいいよね
楽しめない生き方　変えてく　ほら
|kan3=
まだ知らない何かが
どこかで待ち構えている
|kan4=
夜空に星を探し　{{alt-ja|新月|つきないとき}}をすごそ
消えてく三日月さえ　やがては満ちてくから
|kan5=
永遠とは何かなんて
今でさえ判らない
心だけが自分を導くから
|kan6=
終わりのない旅路が
無限に広がってるから
|kan7=
月夜にこの手かざし　尽きない時を飾ろう
満ちてく光つなぎ　耀く夜を越える 


|rom1=
Mawari mawaru sekai no naka 
Hitorikiri wo kanjita
Tomo ni sugosu hito ni mo wakare wa kuru
|rom2=
''Poshitibu''-sa ga tarinai nara
Hashiri daseba ii yo ne
Tanoshimenai ikikata kaete'ku, hora
|rom3=
Mada shiranai nani ka ga
Doko ka de machi kamaete iru
|rom4=
Yozora ni hoshi wo sagashi
Tsukinai toki wo sugosou
Kieteku mikkazuki sae
Yagate wa michite'ku kara
|rom5=
Eien to wa nani ka nante
Ima de sae wakaranai
Kokoro dake ga jibun wo michibiku kara
|rom6=
Owari no nai tabiji ga
Mugen ni hirogatteru kara
|rom7=
Tsukiyo ni kono te kazashi tsukinai toki wo kazarou
Michiteku hikari tsunagi kagayaku yoru wo koeru


|eng1=
I feel alone in this world, ever spinning
Someday I'll have to say goodbye to everyone around me
|eng2=
It's okay to run out when your positiveness runs out
Look, those days where I can't have fun are coming back again
|eng3=
Something I don't know about yet
Is waiting for me, somewhere
|eng4=
Let's spend the night of the new moon
Looking for stars in the dark sky
Even the fading crescent moon
Will become full some day
|eng5=
Even now, I don't really know what "eternity" is
I'm just letting my heart guide me
|eng6=
An endless journey
Spreads out before me
|eng7=
I hold my hands up to the moonlit sky
And decorate an endless time
I connect the growing lights
And cross through the glimmering sky
