Now imagine how much different the tone of the story might be if she was home at the time.
I don't think she moved -- I think she just wasn't home. Reimu complained earlier that miss was never home.
I mean, I'm sure, knowing the writing styles, the ending would have been the exact same.
I'm leaning for things ending the same way ony miss doing the killing or calling pest control. Hell we don't know how Reimu got out, if there was some window breaking in the process, Miss would probably be way less inclined to accept a half rotten, shouting and clearly contaminated talking manjuu into her home.
From an ill girl, lots of despair, it's an abandoned girl.Miss is the only person [I] can rely on and she's not hereeee!
Help!Miss!
Miss!
It's Reimu!
Please open the door!The little ones look weird!
