Wakatta nda yo
Hoka no dare demo nakute
Kono sora ippai no niji wo kakete miseru yo

Itsu made tatte mo todokanai yo
Ato nankai mo kurikaesu nichijou

Oikaketeru no wa itsuka jibun de egaita mirai
Mata dare ka no sei ni shiteta

Wakatta nda yo
Kono mama ja dame na koto
Kono me de midashita "ashita no jibun" wa mou shinjite iin desu ka?
Wakatta da yo
Ikanakucha ikenai koto
Niji no mukou de matteru mou hitotsu no mirai he

Wakatta nda yo
Wakatta nda yo

[Full Version]

Itsu made tatte mo todokanai yo
Ato nankai mo kurikaesu nichijō
Tatoe todoite mo owari ja nai yo
Tsukande mo surinukekieru shinkirō
