Umineko When They Cry Episode 4: Alliance of the Golden Witch

あらすじ

Twelve years after her loved ones were brutally murdered at the annual family meeting, Ange Ushiromiya, now eighteen, is the sole heir of the Ushiromiya family. Ostracized by her peers, Ange seeks companionship in the pages of a diary left behind by her cousin, Maria. The diary offers a precious glimpse of Maria's world--her struggles at school, her friendship with stuffed--lion Sakutarou, and her fascination with magic. It's as if the diary contains the last remnants of Ange's dear cousin...and an opportunity for Ange to discover the magic within herself...
