"Sotsugyo" hito wa atarashii Door
Mata hitotsu akete susumu...

Saigo no hi haya oki o shite
Itsumo no michi o fumi shimeteta
Semakatta kyoushitsu ni ima omoide ga afureteiru
Deatta goro no fuan ya kibou
Dokoka natsukashii namida koboreru...

"Sotsugyo" itsuka kanarazu kuru to
Wakatteita kedo setsunai ne...
"Sotsugyo" kitto wasure wa shinai
Dakara egao de itai yo...

Sukoshi zutsu itsumo no koe ga modori
Nigiyaka ni wa naru kedo
Asu kara wa sorezore no michi
Susumu koto wa shitteita
Tsukue ni tsuketa kizuato nagame
Omoide zenbu kaban ni tsumeta

"Sotsugyo" itsumo namida janakute
Kore kara hajimaru yume kureru...
"Sotsugyo" sore wa wakare janakute
Deai no yokan o kureru...

Itsuka kitto sakura no hana ga
Kono michi ni saki midareru toki...
Hito wa minna mata omoide o
Kakaete aruki hajimeru darou...

"Sotsugyo" sore wa tatta hitotsu no
Mirai no Door no kagi dane...
Mirai no Door o akeru yo...
