Setsunasa wa Setsunasa wa yume wo koete
Hakanasa wa Hakanasa wa toki wo tomeru
Wasurekakete 'ta munasawagi ni
Itami wo oboeta akane-iro no sora
Ai suru inochi tashika na chikara ima wa subete

UNBELIEVABLE Tadoritsuku no wa
Kono kokoro Kono kokoro......
UNBELIEVABLE Tomedonai omoi
Moyashitsukushitai kono mama

Samishisa wa Samishisa wa hikari-banachi
Yasashisa wa Yasashisa wa yami ni kaeru
Idakiau hazu no nai hito to
Tada hitotoki wakachiatta yorokobi
Ayamachi ja nai Dare ka no koe ga kikoeru kedo

UNBELIEVABLE Tatakau dake sa
Hitasura ni Hitasura ni......
UNBELIEVABLE Itsu shika mita yume
Arashi yo Mochisare tooku e

UNBELIEVABLE Tadoritsuku no wa
Kono kokoro Kono kokoro......
UNBELIEVABLE Tomedonai omoi
Moyashitsukushitai kono mama
