Utsuroi kawari tsuzukeru keshiki demo
Kawaranai mono o sagashite kitayo
Yatto mitsuketa niji no tenshi mo
Yoake ga chikazuku to kiete yuku yo
Oshiyoseru nami ga hiite
Suna no shiro ga kuzurete yuku no ni
Todomaru bakari jya sunao ni narenai
Saisho no ippo wa, kimi no chikara hoshi gatte iru
*
Yukaina kodou, kanjiteru nara
'Ai sae areba' to itte hoshii no
Yura yura yureru kimochi wakaru yo
Asu no tamenara namida shite mo ii yo

Keyokyoku*, hito ga shinjiru mono nante
Me ni mienai ai toka yuuki desho
Yo no naka mada suteta mon jyanai
Ato ippo o daseba hajimaru hazu
Hitotachi no nami ga hiite
Tatta hitori kiri ni natta toki
IYAMI na AITSU mo suteki ni kawatte
Hontou no jiyuu wa kimi no naka ni magire konderu
Yukaina kodou, kanjiteru nara
'Ai sae areba' to arukidashite yo
Yura yura yureru kimochi wakaru yo
Asu no tamenara namida shite mo ii yo

Seiza no hitotsu ya futatsu kiete mo
Miwatasu keshiki ga sonna ni kyuu ni kawaru hazunai
Arukidashite kudasai...

Yukaina kodou, kanjiteru nara
'Ai sae areba' to arukidashite yo
Yura yura yureru kimochi wakaru yo
Asu no tamenara namida shite mo ii yo
*Repeat
Asu no tamenara namida shite mo ii yo
