I...knew this person...?You're kidding, right?Now, though, you can't remember a single thing about her.If I'd asked yesterday, this name would have been very familiar to you.It's not just people's memories of her, but anything she achieved during her lifetime has disappeared as well.As a result, you're now living in a world where the victim doesn't exist.She erased her from history. It's as if she was never even born.She's using that ability to cover up her crime.I assume you know what she's capable of.They don't call her 'The History Eater' for nothing.Keine Kamishirasawa didn't just kill this person.
