Itsu ka doko ka de mita you na
Hoshi ga mure tsuki wa aoi yo
Wazuka bakari no hito toki ni
Zutto kokoro ubawareteru

Hoshi ni michibikareta ano hi no yoru
Kokoro ni ukabi tsubuyaita no sa

Hitomi no naka no, hitotsu no regret
Tsukiakari abite hohoende iru
Kokoro no naka no, kesenai regret
Kuyanda kotoba kurikaesu tabi ni
Furueteru
In the blue, blue moon

Sukoshi dake otona ni natta yo
Senobi ni mo nareta mitai da
Owaranai nichijou no naka de
Itsumo kotae sagashiteru

Kimi dake wa ima mo ano hi no mama
Kawaranai ki ga suru no sa

Hitomi no naka no, hitotsu no regret
Hashiridasu koto de wasurerareru no ka na
Kokoro na naka no, kesenai regret
Itamisura nareta chippoke na ore ga
Waratteru... In the blue, blue moon

Hitomi no naka no, hitotsu no regret
Tsukiakari abite hohoende iru
Kokoro no naka no, kesenai regret
Kuyanda kotoba kurikaesu tabi ni
Furueteru
In the blue, blue moon

Hitomi no naka no, hitotsu no regret
Kokoro no naka no, kesenai regret
Hitomi no naka no, hitotsu no regret
Blue, blue moon

Oboeteru
In the blue, blue moon
