This is the romanization done based on your lyrics while listening to the music:
Hitomi wo tojite omou saki wa
Mirai dake sa
Mitsukeraretara sono manazashi wa
Kokoro toki hanate sou
Kotoba no kabe wo BUCHI yabutte
IMEEJI no sekai ni tobi notte
Yukue shirezu no kokoro wo kagayakeru ashita e
Tobunda Let's get start!
1,2,3 de tobunda!
Okonomi no ha wo te ni ire
Awai kaze ni notte
Dreamin' sun de hikatta
Nijiiro ni mi wo makasetara
Tobitateru sa
Sora no kanata mademo yukou
Yobu koe ga kikoeru
Hitomi wo tojita sono manazashi de
Hitomi wo tojite sou kagayaita hibi |
