Umineko no Naku Koro ni

Synopsis

During dinner, no one admits to giving Maria her umbrella, leaving them to wonder if there is an additional resident among the eighteen guests. After everyone finishes eating, Maria reads a letter she claims to have received from Beatrice earlier, stating that Beatrice will take everything from the Ushiromiya family if no one can solve the portrait's cryptic epitaph. Later, George proposes to Shannon, and asks her to give her reply the next day by wearing the ring on a finger of her choice. The following morning, Krauss, Rudolf, Rosa, Kyrie, Shannon, and Gohda are missing, and the phone lines are out. Natsuhi is informed of a strange symbol painted in red on the outdoor tool shed. While the others investigate the matter, Battler, Jessica, and George follow to discover the missing people brutally murdered inside, with Shannon wearing George's ring on her left ring finger.
