|This article is about a character in Umineko no Naku Koro ni.|
Jessica's classmate and best friend. She has a fast-paced personality but is good at winning others over. Just before the school festival, she seems to have found the boyfriend of her dreams.
(Translated from Entergram's Umineko Saku website.)
Saku has long black hair and wears a green school uniform.
Saku and Jessica have an argument, and so Jessica gets help from the demons Zepar and Furfur to make up with her. The demons tell Jessica to turn her socks inside-out and give candy to Saku in private. Jessica tries this out the next day, and when Saku sees how ridiculous Jessica is acting she laughs and apologizes for their argument.
Saku doesn't appear, but she is mentioned as having asked Jessica to write a play for a culture festival. It's also shown that she was to act as the prince in the play, much to Jessica's ire.
- Saku is commonly known as Saki however this is a mistranslation.
