Mune ga dokidoki
Hyaku nen buri no seikimatsu nake to iwarete boku ha waratta
Hisakataburi no seikimatsu hiroi sekai he tobidashiteyuku
Kodomo no koro ni wakari kaketeta koto ga
Otona ni natte wakaranai mama
Eraku mo naishi
Rippa demo nai
Wakatteru no ha mune no dokidoki
Kotae demo nai hontou demo nai
Shinjiteru no ha mune no dokidoki
Mune no dokidoki dake
Kakkoii ka ha wakaranai kedo
Osaekirenai yume wo mitanda
Sakusen tatete jitto matsu yori
Kodomo no mama de butsukatteyuku
Uchuu no hate ni hata wo tateta toshitemo
Uchuu no nazo ha wakaranai mama
Eraku mo naishi
Rippa demo nai
Wakatteru no ha mune no dokidoki
Kotae demo nai hontou demo nai
Shinjiteru no ha mune no dokidoki
Eraku mo naishi
Rippa demo nai
Wakatteru no ha mune no dokidoki
Kotae demo nai hontou demo nai
Shinjiteru no ha mune no dokidoki
Mune no dokidoki dake
Heartbeat
After a hundred years, the end of the world is said to be near, and I laughed
After a long time, I'm going to jump into the wide world
What I understood when I was a child
I still don't understand as an adult
Not clever
Not beautiful
What I understand is the heartbeat in my chest
Not an answer, not the truth
What I believe in is the heartbeat in my chest
Just the heartbeat in my chest
I don't know if it's cool, but
I saw an uncontrollable dream
Rather than waiting quietly with a strategy
I'll collide as a child
Even if I raise a flag at the end of the universe
I still don't understand the mysteries of the universe
Not clever
Not beautiful
What I understand is the heartbeat in my chest
Not an answer, not the truth
What I believe in is the heartbeat in my chest
Not clever
Not beautiful
What I understand is the heartbeat in my chest
Not an answer, not the truth
What I believe in is the heartbeat in my chest
Just the heartbeat in my chest
