Niji (虹; Rainbow)

Kasanariatta aozora ga bokura no yukute ni hirogaru
Ookiku shinkokyuu shite yuru'n da kutsu no himo wo musubu
Kawaru kawaru kono sekai no himitsu wo mou ichido mitsukeyou
"Jibun rashiku yanda" tte "tanin rashiku nan na" tte.

Tatoeba soko kara hajimaru mirai ga tashika ni aru toshite mo
Mada bokura futashika na michi no ue.

Hashiridashita sekai ga boku wo asu he izanau
Nagarete yuku keshiki wa yagate hikari to kawaru
Aru ga mama no negai wo komete mata fumidaseba
Tooku mieta sekai ga nana-iro no niji he kawaru.

"Tsukareta'n da" to nageku yori "koko made kita" tte yorokobu
Sonna fuu ni omottetai sonna fuu ni ikite itai
Yamanu koto nai kutsuoto wo mata ippo ippo tashite kou
Sono hohaba wa itsu datte fuantei de attatte.

Tojite wa hiraita mune no uchigawa ni fureyou to shite mitara
Dare mo mina uzuku you na kizu mo aru.

"Atarimae" no sekai ga boku ni kiseki wo miseru
Haruka mieru keshiki ga tooku tooku hirogaru
Irotoridori no ai ga boku wo tsutsumikomu kara
Yagate todoku mirai mo ikutsu mono niji he tsudzuku.

Tada hitotsu no sekai wo bokura no iro ni someru
Togireru koto nai michi sono saki wo mata mitsumeru.

Hashiridashita sekai ga boku wo asu he izanau
Nagarete yuku keshiki wa yagate hikari to kawaru
Aru ga mama no negai wo komete mata fumidaseba
Tooku mieta sekai ga nana-iro no niji he kawaru.
