Human Equation (Ningen Hoteishiki)

Ichi, ni de hajimaru ningenrēsu
Kyōsei sanka no batsu gēmu
Ki ni naru aitsu wa saki e iku
Mō todokanaito kata otosu

Boku wa dōdatta nda nani ka nokoseta no ka
Kono mama owatcha manzoku dekiyashinē

Nanimoshinai de waratte inai ka
Saisho kara nigete inai ka
Nanimoshinai de urayande inai ka
Tachidomatte kangaenaose

Nibiiro ni nigotta me no sei de
Dō shiyō mo naku utaga~tsu teru
Chiheisen ni kieru yume o mite
Kakugo mo yaruki mo nakuna~tsu teru `

Chōshi wa dōdesu ka' ukagau hito no koe
Egao no uragawa kanashiku narimashita

Nanimoshinai de waratte inai ka
Saisho kara nigete inai ka
Nanimoshinai de urayande inai ka
Tachidomatte kangaenaose

Yatto unazuita mayou hima mo nai na
Tsuyo gatte shuyaku no utawoutau ndaro

Nanimoshinai de waratte inai ka
Itsu made mo nigete inai ka
Boku no tame ni hikaru shūchaku-ten
Mite mitaku wa nai no ka
