If anyone is interested, information about this title is available on TV Tropes, which does a pretty good job explaining what the frak is going on. Total spoilers, though.
FYI, Japan has very stringent rules on waste disposal and there are special taxes on oversized garbage, like home furnishings. I can understand that extra fee now.

Thanks for the spoiler, I'm gonna take this out of my reading list. I hate it when it's supposed to have updated and it turns out it was last updated a month ago...
