It gets even even better when you realize that as Battler wrote umineko(with Ikuko) Akasaka wrote higurashi (with Ooishi), and maybe this ep is actually the truth and it's all about the history of Akasaka trying to understand the tragedy of hinamizawa(with Oiishi's help), using Rika, as the protagonist and portraying her as oyashiro's reeincarnation because of her warn 'prevision', which wasn't pretend to be a 'big deal' saved his's wife's life, and made him "believe in magic" accepting her as a divine being.
