Nagareru kumo no kirema ni niji wo mita
Dakedo kokoro wa dare ni mo mienai
Taisetsu na mono shinjiru mono ga areba
Hitomi wo tojidemo kizuna wo kanjiru
Tatoeba yozora ni hikaru hoshi ga
Mugen ni hirogaru you ni
Shiawase no katachi mo kagirinaku aru hazu sa
Aishite iru dare yori anata wo
Kawaranai kono omoi eien ni nareba ii
Kitto itsuka mirai ni naru kyou wo koete
Heart of rainbow kono te de tsukamunda
Kanawanai yume todokanakatta koi yo
Omoi doori ni naranai sekai de
Yaritai koto wo gaman shite wa ikenai
Ima wo ganbareba kibou ga chikaduku
Kinou wa zenbu wasurero
Donna toki mo mae wo miro
Jiyuu ni ikiru michi wa iku toori mo aru hazu sa
Shinjite iru dare yori anata wo
Kawaranai kono omoi eien to yobeba ii
Kitto itsuka mirai ni naru kyou wo ikite
Heart of rainbow ashita wo tsukamunda
Naze tooi mirai bakari wo
Yumemite nayande shimau no ka
Kinou no mirai wa ima sa!
Mayowazu hajimereba ii
Aozora to daichi no haruka kanata
Namida no ato ni ai to iu na no niji wo oikakete
Tatoe sugu ni tadori tsukenakute mo
Sono ippo wo fumidasu yuuki wo mote
Aishite iru dare yori anata wo
Kawaranai kono omoi eien ni nareba ii
Kitto itsuka mirai ni naru kyou wo koete
Heart of rainbow kono te de tsukamunda
Heart of rainbow ai wa ikiterunda
