Mou modoranai ano hibi ni
Ima chikau kanashimi ni uchikatsu
Koto

Mukizu no mama koerarenai
Kimi ni mata deau tame no tabi wa
Ashiato mo moetsukite

Kimi ga itsuka oshiete kureta
Kokoro no yakudou ga karitateru
Mirai made wa ubawaretenai

Sore wo shitteru kara ikeru
Just go on!

Kimi ga hoho emo nara
Kimi ga utaeru no nara
Ore ga nozomu subete ni kaeru
Kimi ga kureta yuuki
Kimi ga kureta yasashisa
Mou e wo mitsumete
Aruku chikara ni naru

Tsuyoku kage na ochiru nara
Sono mikobo tsuyoi hikari ga aru
Kara

Mada hashireru mada takeru
Mou ichigo nakushi kaketa kimi no
Kimi ashisa torimodosu Ano hi egao ga kaete kureta
Toza sareta kokoro wo toki hanachi
Tada sore dake wo mune ni dakeba

Touna kurushi mitemo koeru
Let to fight!

Kimi ga utsumuku nara
Kimi ga a tsuzukusu nara
Ore ga mamoru subete ni kaete
Kimi ga kureta kokoro
Hito wo aisuru tsuyosa
Yami ni kuidasu kagayaki eto kawaru

Mirai made wa ubawaretenai

Sore wo shitteru kara ikeru
Just go on!

Kimi ga hoho emo nara
Kimi ga utaeru no nara
Ore ga nozomu subete ni kaeru
Kimi ga kureta yuuki
Kimi ga kureta yasashisa
Mae wo mitsumete...

Kimi ga utsumuku nara
Kimi ga a tsuzukusu nara
Ore ga mamoru subete ni kaete
Kimi ga kureta kokoro
Hito wo aisuru tsuyosa
Yami ni kuidasu kagayaki eto kawaru
