At least we can be sure that Toriko's leg will be easily sewn back. I remember Josaku saying that if Toriko had his leg with him, it would be easy to simply attach it back, while growing is another story.
I like how Shima continues to taunt readers with Joa/Jirou game. I hope they will be indeed related, even if not through blood. One says that it's time for him to appear, the other one arrives to the stadium. Ichiryuu and Midora have affilated factions, Jirou is yet a loner. And now a third side appears.
And also, back at the beginning of the manga (or maybe later, but certainly in first 100 chapters), there was a page with the text that a group of powerfull people was joining or something. I don't remember who said it, or when exactly, but it had a profile of Jirou turning to the left into the page, that guy with his helmet or mask having trident of black bar openings (we see him from time to time on big gatherings) and a guy with winged helmet. Someone other too I think. Just checked Grinparch meeting, it's him who says that - ch 60 pg 15. http://www.batoto.net/read/_/38913/toriko_ch60_by_map-scans/15 Raised my suspicions even at the first reading.
