Kokoro no Kagi (Heart's Key)

Tsuki ni yurete iru

Bokutachi no mirai zu ni

Itsuka kanaete ku asu wo egaku yo

Naku senai negai wo kizande

Namida no kazu ga

Dareka no kizu wo tsutsumu nara

Nani mo kowakunai nando mo shinjiyou

Hatenai sora ni ryoute hirogete

Nakanai youni tsuki wo miagete miru

Kanashimi mo hikari yobunara

Modorenai to shite mo kamawanai

Kagayaita yume ga sagasu mirai ni

Kakegae no nai omoi tsudzuiteru kara

Doko made mo aruite yuku nda

Tada hitotsu kokoro no kagi wo nigiri shimete

Minamo ni utsushita

Egao wa oboete iru

Kimi no yasashisa wo mune no itami o

Bokutachi ga deaeta riyuu wo

Tsurai kimochi wo

Hitotsu mo kotoba ni shinai mama

Hohoemi no naka de sayonara shita kedo

Hatenai sora ni zutto kienai

Kimi to kazoeta hoshi wo miagete miru

Kono negai todoku made

Modorenai michi wo susumitai

Kagirinai yume ga kageru yoru ni mo

Kakegae no nai omoi tsudzuiteku kara

Itsumade mo tsunagaru youni

Tada hitotsu erabu tobira wo shinjite iru

Kimi no koe ga konnani chikaku de kikoeru yo

Asayake ni somaru daichi wo

Owarinai tabi de hajimeyou forever

Hitori janai to oshiete kureta

Kimi ga iru kara ima tsuyoku nareru

Kono kizu ga hikari ni naru made

Kesshite nakanai to kimeta nda

Hatenai sora ni fureru mirai ni

Kakegae no nai omoi tsudzuiteku kara

Doko made mo aruite yuku nda

Tada hitotsu kagayaku kagi wo mune ni daite

Zutto daite
