Umineko WHEN THEY CRY Episode 1: Legend of the Golden Witch, Vol. 2

Six people are dead, and Battler and his remaining relatives slowly come
around to addressing the terrifying reality of their situation: Either
one of their number is a murderer, or there is a nineteenth person on
the island who wants the Ushiromiya family dead. Regardless, the killer
seems to be following the inscription beneath the portrait of Beatrice,
the instructions for finding the elder Ushiromiya's vast treasure of
gold. But each line of the inscription calls for more death, more
blood...and the revival of the witch Beatrice herself... Will any remain
alive to see the end of this mystery?
