Kokoro ha hane wo motteiru
Yukusaki michi ga mienakutemo
Omoi ha tsuyoku maiagaru
Susumuu to kimeta chikai

Eureka hitori no tsumori ga
“Shinjiru koto” itsushika moratteta

Rasen wo egaku youni senritsu ha kuu wo kiru
Ima no watashi ka sore ijou michibiku rain
Zankyou no sono naka ni kienai kimi ga ita
Motto yukeru

Kakushita mune no netsuryou ha
Hakarenai hodo ni mashiteyuku
Kono mi ni matou koto dake ga
Shimei wo hatasu akashi

Eureka dareka no rikai ha
Tsuyosa ni naru hajimete kanjita no…

Kuuzen no sadame tote massugu ukeiryou
Watashi ga watashi de aru koto mitomeru sain
Kyoumei suru shoudou kidzukeba sukoshi zutsu
Tsuranatteta

“You did not disappear, stood there,
In the reverberation, eureka, eureka…”

Eureka
Mitsuketeshimatta
Kokoro no oku sono oku michisuu no yurameki wo

Rasen wo egaku youni senritsu ha kuu wo kiru
Ima no watashi ka sore ijou michibiku rain
Zankyou no sono naka ni kienai kimi ga ita
Motto yukeru
