ok really? no one should be surprised by this at all. one should expect this kind of development in this manga. i just didn't think i would actually see it. it is just too lame of a development.
its basically a "the power of friendship will save us" type of thing. obviously tsuna won't die, and i certainly did not think he would take out spade in that one attack, but this is a sort of predictable turn of events.
i suppose now after this arc the manga will end.
