I remember when first news about naruto gaiden comes, some NS fans said the tittle is Naruto the Seventh Hokage and The Scarlet Moon.
Oh ... that scarlet moon part ... i thought maybe theres little spark of hope after all.
Turns out to be soap opera with 'Whost MY MOMMY' drama as its theme.
So the scarlet moon part literally means nothing, just empty word ... well not entirely empty, its mean give false hope to anti ending fans.
