Mitasarenai to wakatte mo motomeru no ka Eien wo
Tsumibito to seija no hazama de setsuna no toki tsunaide

Owari no nai ayamachi ni
Irodorareta sekai wa
Kaseki no mori ni sugata wo kaete
Kanashimi no shinwa wo tsumugu

Itsu ka karada sae kaze ni nari daichi e kaeru darou
Da kedo kokoro wa doko e yuku no ka hito wa kotae wo shiranai
Soshite arukidasu hikari naki yoru wo yuke
