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

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

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

Hitotsu no kagi
Boku wa soko ni
Mada mirai wo miteiru

Mune ni nokoru kotoba, kioku mo
Kizu ga itamu ano hi no koto mo
Subete ga jibun wo 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 wo shimesu boku wa sore wo furiharatta
Kono michi wo susundeikeba
Acchi no keshiki a wakaranai kedo
Hougaku wo yudaneru koto ga imi no nai koto to youyaku satotta

Erandekita kotoba, michi ga
Tashika ni ima jibun wo tsukutta
Subete wo tsunaide umareta key darou
Dare mo ga hajimete egaiteku michi
Nozonda ashita wo 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 wo tomeru na kinou no jibun ga iu darou

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

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

All choice leads to my key
I hope you understand
