planetes 삽입곡 Secret of the Moon 작사/작곡/노래 : 黒石ひとみ(쿠로이시 히토미, 노래 부분은 HITOMI로 표기)
when I wish upon the moon
deepest dreams
A spark of love
leaps in the sky
take me into your world
when I wish upon the moon
dreams come ture
I bless the day
you found me
I'll always still with you
A secret of the moon
let me be the sun that light up your ways
I live for you
I'll live for you
