Hyakunen buri no seikimatsu
Naketo iwarete boku wa waratta
Hisakata buri no seikimatsu
Hiroi sekai e tobi dashite yuku

Kodomo no koro ni wakari kaketeta koto ga
Otona ni natte wakaranai mama

Eraku mo nai shi
Rippa demo nai
Wakatteru no wa mune no DOKIDOKI

Kotae demo nai
Hontou demo nai
Shinjiteru no wa mune no DOKIDOKI
Mune no DOKIDOKI dake

Kakkoii ka wa wakaranai kedo
Osae kirenai yume wo mitanda
Sakusen tatete jitto matsu yori
Kodomo no mama de butsukatte yuku

Uchuu no hate ni hata wo tateta to shite mo
Uchuu no nazo wa wakaranai mama

Eraku mo nai shi
Rippa demo nai
Wakatteru no wa mune no DOKIDOKI

Kotae demo nai
Hontou demo nai
Shinjiteru no wa mune no DOKIDOKI

Eraku mo nai shi
Rippa demo nai
Wakatteru no wa mune no DOKIDOKI

Kotae demo nai
Hontou demo nai
Shinjiteru no wa mune no DOKIDOKI
Mune no DOKIDOKI dake
