[Verse 1]
Boku no mitenai sono toki ni mo
Kimi no hibi wa tashika ni sonzai shite
Boku kara wa mienai shiranai tokoro de
Kimi wa naiteta no kamo shirenai

[Pre-Chorus]
Mune wo eguru you na kanashii wakare wo shita
Kono sekai de bokura mata deatte iku
Me wo miharu you na hoshikuzu nara
Aozora no naka demo hikatteiru

[Chorus]
Uragawa no sonzai
Bokura wa marukkiri chigau
Dakara sono subete wakatte agerarenai
Demo daiji na sonzai
Chigau kara sasaeaeru
Tarinai tokoro wo kimi ga hamidashite kureru

[Verse 2]
Boku no shiranai kimi no kako mo
Kimi no shiranai boku no ima made mo
Furetai to negau you na kanawanu omoi ga
Kitto kono saki wo tsumuideku
[Pre-Chorus]
Udaru you na natsu ga fuyu ni kogareru you ni
Yawaraka na haru ga aki wo tsutsumu
Buatsuku hirogaru amagumo nara
Aozora wo kakushiteiru dake

[Chorus]
Uragawa no sonzai

Dakara kore kara mo tabun mata surechigau
Demo daiji na sonzai
Chigau kara itoshiku omou

Kimi no mitenai sono toki ni mo
Boku no hibi wa tashika ni koko ni atte
Kimi kara wa mienai shiranai toko demo
Boku wa kimi wo omoi ikiteru

[Chorus]
Uragawa no sonzai
Bokura wa marukkiri chigau
Dakara sono subete wakatte agerarenai
Demo daiji na sonzai
Chigau kara sasaeaeru
Tarinai tokoro wo kimi ga hamidashite kureru
Boku ga sashidashite ageru
