This is even more heavily implied with the fact that she grants the child the power to become a witch for two days which is what she gave Beatrice.She shares the same distinctive laugh asВ Houjou Satoko fromВ Higurashi no Naku Koro ni, and also as the same penchant for making traps. In Umineko no naku koro ni no TsubasaВ it is heavily implied however that she set the story ofВ HigurashiВ in motion by granting with certainty Takano's wish to become a god which would explain why Bernkastel always says that she was trapped in a witch's game which was most likely Lambdadelta's CertaintyДЄlso inВ Umineko no Naku Koro ni TsubasaВ it shows a scene that is implied to be Lambdadelta grantingВ Yasu's wish to become a witch. However, in both the sound novels and in an interview withВ Ruykishi07, not only did Lambdadelta not finish readingВ HigurashiВ by the time Bernkastel offered to spoil the ending, Ryukishi07 stated that her similarity to Takano was nothing more than a red herring used to throw off readers who readВ HigurashiВ first In addition,В Shannon's real name 'Sayo' has a similar lecture to the compound дё‰е››.The 'game' she played with Bernkastel may be the battle that took place in the world ofВ HigurashiВ with the battle betweenВ RikaВ and Takano being the purpose of the game. This is likely simply a reference toВ Higurashi, because the events ofВ HigurashiВ precede those ofВ UminekoВ by three years (HigurashiВ taking place in 1983 В UminekoВ in 1986), and she is said to have lived for a thousand years.ДЄnother similarity would be her name 'Lambdadelta' (О»Оґ) which represents thirty-four when using Greek numerals and 'Miyo' (дё‰е››) can be translated as 'three, four' in Japanese, strengthening their connection. She is very similar toВ Takano MiyoВ fromВ Higurashi no Naku Koro niВ in appearance, personality, and goals.
