Setsunasa wa setsunasa wa yume o koete
hakanasa wa hakanasa wa toki o tomeru
wasure kaketeta muna sawagi ni
itami o oboeta akane iro no sora
aisuru inochi tashika na chikara ima subete

UNBELIEVEABLE tadoritsuku no wa
konno kokkoro konno kokkoro...
UNBELIEVEABLE tomedonai omoi
moyashitsuku shitai konno mama

samishisa wa samishisa wa kikari hanachi
yasashisa wa yasashisa wa yami ni kaeru
idakiau hazu no nai hito tto
tada hito toki wakachiatta yorokobi
ayamachi jya nai dareka no koe ga kikoeru kedo

UNBELIEVEABLE tatakau dakesa
hitasura ni hitasura ni...
UNBELIEVEABLE itsushika mita yume
arashi yo machisare tooku e

UNBELIEVEABLE tadoritsuku no wa
konno kokkoro konno kokkoro...
UNBELIEVEABLE tomedonai omoi
moyashitsuku shitai konno mama
