Lirik Lagu "Last Promise" oleh Erii Yamazaki

Kimi to saigo no yakusoku o shiyou

Kizudarake no mama de shimaikondeta kokoro
Kimi wa sotto hiroiageta
Kurikaesu hibi ni dou shiyou mo naku utsumuita toki
Gyutto dakishimete kureta
Zutto koko de kimi to futari de
Yozora nagareru
Hoshi o mitsuzuketai

Kimi to saigo no yakusoku o shiyou
Sekai kara watashi dake kiete shimatte mo
Kizukarenakute ii kono mama de itai
Kizukareta kono kimochi itsu made mo eien ni

Machi no hito wa dare mo eki e to mukau nagare
Naze ka oitekareta you de
Hitoribocchi da ne to
Tsubuyaku watashi no migite o
Nan mo iwazu ni tsutsunda

Wakare tsugeru yokaze ni nosete
Kimi ni sayonara iwanakya ikenai ne

Tooi mukashi ni yakusoku o shita ne
Ano basho de hontou no kimi ni fureta toki
Tojikomete ita namida ga afurete
Deguchi no nai kurayami ni hikari ga mieta ki ga shita

Hana ga saku sono isshun de mo konayuki ga mau shunkan mo
Kimi to itakatta
Kanawanai to omotteru tte kimi ni ittara okorareru ka na

Kimi to saigo no yakusoku o shiyou
Sekai kara watashi dake kiete shimatte mo
Kizukarenakute ii kono mama de itai
Kizukareta kono kimochi itsu made mo eien ni
