She's kind of poorly handled in the anime. In the novel, Kouichi describes her as being absurdly, artificially cheerful, which makes him uncomfortable. It's not evident why she chose to start attacking people at the Inn in any adaption other than as a deus ex machina for more people to die (which is why it's not present in the manga or film, which have significantly lower body counts than the anime or novel).
