Quite deserved. The chapter which got Toriko the top was the climax chapter of the previous arc. Considering how the author managed to keep the tension since then, I believe Toriko will do good for quite some time. This will hopefully influence the sales for the
2nd half of 2012.
Toriko alongside OP and SnK are my personal top three. I want all of them doing good in sales, especially Toriko, since the manga deserves imo more credit. Hopefully Toriko will get back in the top 10,
like last year.
Last but not least, it seems the "kids manga" argument has been drooped a few times in connection with Toriko. Well each his own perspective, I respect that. It is fine if it is used to describe the manga, but completely different matter if it is used to mock. Therefore I don't like that remark.
