Funny how One piece has almost more than rest of the chart combined. Anf Bleach is dropping~. This is only Japan tho, it's probably different in the U.S. for example, seeing that OP is far less popular there, but I think the numbers speak for themselves. It's really a matter of opinion tho, because I, personally, enjoy FT more than Naruto or Bleach right now.
