Kago no naka no bokura wa

Tobitai aozora mitsuketa ano toki kara

Kokoro wa mirai ni hikareteru

Henkyou de kuukyo na kankyou no kago wo kowashi nigetaku naru

Tobitatsu tsubasa ga senaka ni nobita hi kara

Kokoro wa mirai ni mukatteru

Aozora no kanata jiyuu ni tobitai'n da

Kaze ni nomare katachi wo nakushita kumo no you ni

Nagare ni mi wo makasete wa kono kimochi wo uso ni suru

Sore dake de mou juubun da

Dokomademo habataite

Kagi wo akete ori no soto he

Kago no naka no bokura wa
