Mune ni nokoru kotoba, kioku mo
Kizu ga itamu ano hi no koto mo
Subete ga jibun o kaeru kagi darou

Riyuu mo naku bokura wa tada sutaato
Ni tatta wake janai
Iki o hajime kimi wa hidari boku wa sore
O migi ni magatta

Dare hitori jama wa saseru ka
Hajimete jibun de eranda michi da
Okubyou ni amayakashiteta kako
O koukai shita toki ni umareta

Hitotsu no kagi
Boku wa soko ni
Mada mirai o miteiru

Mune ni nokoru kotoba, kioku mo
Kizu ga itamu ano hi no koto mo
Subete ga jibun o kaeru kagi darou
Mitero korekara to sakenda koto mo
Kazu aru wakare tsunaide kono basho
Eranda no darou

Dochira e iku futatsu no yukue
Chuuou ni tatta akuma ga
Niyakenagara hitotsu o shimesu
Boku wa sore o furiharatta
Kono michi o susunde ikeba
Atchi no keshiki wa wakaranai kedo
Hougaku o yudaneru koto ga imi
No nai koto to youyaku satotta

Bring it on, my destiny
Erande kita kotoba, michi ga
Tashika ni ima jibun o tsukutta
Subete o tsunaide umareta key darou
Daremo ga hajimete egaiteku michi
Nozonda ashita o mukae ni ikou ka
Bring it on, my destiny

(all choice leads to my key)
(I hope you understand)

Temptation branch point
Sweet damon's instruction
Kyoumi nai na kimi no iken wa kikoenai yo kikoenai to
All one step have the meaning
That's make up all reasons
Tsugi no ippo o tomeru na kinou no jibun ga iu darou

Erandekita kotoba, michi ga
Tashika ni ima jibun o tsukutta
Subete o tsunaide umareta key darou

Mune ni nokoru kotoba, kioku mo
Kizu ga itamu ano hi no koto mo
Subete ga jibun o kaeru kagi darou
Mitero korekara to sakenda koto mo
Kazu aru wakare subete ga kono basho
Eranda nodarou

All choice leads to my key
I hope you understand
