Setsuno was just badass in this chapter and her technique is a very terrifying one.
I guess that the fight between her and Chiyo will be awesome.
About the rest, that Nitro seems pretty strong and thus the coocks will have an hard time dealing with him, but that's wat will make this arc even more epic.
I wonder what is the third faction's aim...
The third faction are also after God. It was mentioned that the king of Jidal Kingdom left his position to search for God.
A thing just came to mind. Last national treasure, saiseya Mohyan Shaishai - member of the 3rd faction. That would boost their reputation and power significantly. If Zaus is their member as well, 3rd faction is shaping up to be a legitimate contender for IGO and Bishokukai. As noted before already, their information network is so good they even knew about Bishokukai having Nitro.
I might even say that Zaus may be the one who attacked Teppei... Shimabukuro kept his identity secret and apparently he's a very skilled cook. Anyway, the guy who was during the Four Beast invasion and attacked Teppei is definitely a cook for me, he said he felt like he was gonna be " cooked ".
http://image-upload.de/image/OdAi02/f0c74d51c2.jpg look different from the ones we usually see. Especially that worm-like one. And when Setsuno uses her air-pressure technique, you see blood and innards and not electronic-device-things like you see when Mansam wrecks havoc http://www.mangapanda.com/toriko/222/5 I'm not saying those are Nitro. But I would think it weird if all those grotesque Nitro-look-alikes where GT-Robots and why they would spill blood and stuff. Maybe the Authors just likes to draw creatures like that..
but what happens to Jirou? which side could he be?
