Lyrics:

kono hiroi sekai no naka deau beki hitotachi ga
mado no mukou niji no mukou ni mieru kiduiteru hazu

kyuukutsu na omori wo nuide kimochi wo yurushite
saa mimi wo sumashi sono toki wo matte
ima mezamenasai

oozora ni egaita chiisana yume wo taisetsu ni shiyou
sou sureba itsumo shiawase ni nareru kitto
