When you think about it, it’s funny that in administrating something as complex as hell, there aren’t more clerical errors. But whether due to clerical error or the “cursed result of the union between a human and a demon”, Amy was “not like the other demons”. But while on the surface Amy was pure and innocent and childlike, underneath she’s not all that she seems, and she exploited her childlikeness for demonic purposes.
The way the story is set up, I think many people would find it humorous, and laugh at Amy’s antics. For me, it wasn’t to my taste simply because of a personal not liking people who are not children pretending to act like children. I never felt any sympathy with Amy, but neither did I feel any sympathy with her victims. As a result, this story somewhat passed me by rather than brought me in.
