In contrary to some of the other people's opinion, i acutally found this anime extremely predictable. After watching a few episode, and each time a new "villian" is introduced, i said to myself "Heh, I bet the villians are all gonna turn good in the end." I also predicted the all happy ending, which i found really annoying, seems a bit too
unrealistic.
A prediction i made that didnt come true was that Izumi-kun was acutally Echi-kun after he died, and became a shinigami. That would add another layer to the plot.. but it never happen
