Yakusoku (Promise)

Fukai yami no naka de kimi no koe ga kikoeta
"shinjiteru" tada hitokoto boku no kokoro ni hibiite kita
Itsumo kimi ga soba ni ite kureta ne
Itsumo boku ni yuuki kurete ita
Bokutachi no mirai wo mamori tsuzukeru tame ni
Taisetsu na kimi ni yakusoku suru yo
Boku wa akiramenai
Motto motto boku wa boku wo koete
Kitto kitto kitto

Toki toshite hito wa dare mo yume wo miushinatte shimau
Ayamachi ya kizutsuki kata mo jidai wa kurikaesarete iku
Doushite shinjiau koto ni aragau no?
Doushite unmei to iu hikari kesu no?
Bokutachi no mirai wa kono te de mamorinukitai
Zenryoku de idomu koto no imi wo
Kimi ga oshiete kureta kara

Bokutachi no mirai wo mamori tsuzukeru tame ni
Taisetsu na kimi ni yakusoku suru yo
Boku wa akiramenai
Motto motto boku wa boku wo koete
Kitto kitto kitto
Motto motto kimi wa kimi wo koete
Kitto kitto kitto
