Like i said it seems she's a new witch,
Like the title said , The END of the golden witch . Actually i don't remember how many witches have a portrait. Beato
and her ? The hand at the right-bottom is a huge hint about who this person can be.I think we're reaching the end of this serie.
her name? if she hasn't a name in the game , i guess we should call her U.N ( No , no reference to U.N Owen was her ? Well you'll tell me, umineko is close to Agatha's book .)
