Lyrics:
Tomei na kame wo tsuke rareto yo datta
Mie nai mise nai hounto no koto sae
Tashika na mono ga yuragi hajimeta to shitara
Chikai no hata o doko ni tatero to iu no darou

Kono mi ni kuzamare ta sadame ga michibiku
Aragau koto no saki e

Kono te o ima tsutatteru atsui chi ga hashiru yo ni
Kusari o tetsua ni kae sai tsuyoku
Kodoku o tada mitomeru sore ga ishi o motsu koto
Ashikase tsukerarete mo takaku

Believe My Dice kitto kotae nado nai darou
Dakara yuzure nai sai o furu no wa kono te da to

Toku made hashire ba
Nugui sare ta darou ka
Senaka ni karan da kage wa mirai datta
Annei ni iikiru koto mo yurusare nai nara
Isso subete kono inochi ni shitagaeyou ka


Chigiri o kawasu no wa onore to kime tara
Yami ni sae fumidaese yo

Kono me ga ima sadameru atsui kumo no mukou e
Hikara zu tomo haikari ga aru to
Mayoi no naka susumo u
Sore ga michi ni naru koto mie nai hodo tashika na asu e

Believe My Dice itsumo korogari me noi taku shite
Subete wo yudane you sai o furu no ga kono te nara
Kie nai kagero wa dare ni mo yurameku
Ma do wa sareuragirare soredemo mada
Arukidaseru no sa

Kono te o ima tsutatteru atsui chi ga hashiru yo ni
Kusari o tetsua ni kae sai tsuyoku
Kodoku o tada mitomeru sore ga ishi o motsu koto
Ashikase tsuke rare te mo takaku
Believe My Dice kitto kotae nado ira nai sa
Shinjiru mono wa so sai o furu kono te dake darou
