Hibari Rules!! Great chapter.
Hibari is crazy!! This mofo is the "sky gaurdian", but says "one day I'll even bite up the sky itself". How gangsta is that?
Now I think we'll see 1 of the most important slices of the Vongola/Shimon history. And then it might be time for a Yammamoto appearance and final fight.
I actually expected him to do that (tiny spikes) since I saw the technique a chapter before this.
Nonetheless, I agree that Hibari did somehow thought of Tsuna when they were talking about the sky.
