Intro:
Ningen nante lalala lalalalala
Ningen nante lalala lalalalala
Ningen nante lalala lalalalala
Ningen nante lalala lalalalala
Ningen nante lalala lalalalala
Ningen nante lalala lalalalala
Nani ka ga hoshii oira
Sore ga nandaka wakara nai
Dakedo nani ka ga tari nai yo
Ima no jibun mo okashii yo
Sora ni ukabu koma ha
Itsuka doko ka he ton de yuku
Soko ni nani ka ga arum daro u ka
Sore ha dare ni mo wakara nai
Ningen nante lalala lalalalala
Ningen nante lalala lalalalala
Ningen nante lalala lalalalala
Ningen nante lalala lalalalala
Ningen nante lalala lalalalala
Ningen nante lalala lalalalala
Ningen nante lalala lalalalala
Ningen nante lalala lalalalala
