And if Erika's corpse was used, it actually gives her a real purpose for appearing in Umineko actually.

Knox's 8th. There was no foreshadowing that Erika Furudo's corpse was used in Episodes 1-4, and that the red means anything more than "Erika Furudo never existed in any physical form, including a corpse" on the island in the first four games. The series is solvable with Games 1-4. Therefore, it would stand to reason that someone introduced in the 5th Game cannot be involved!
