It seems you have never been punched there by a unrully kid, no one recovers that fast, even if you are not in pain you feel unconfortable for a long while
the sequence of Phos dying is one of the highlights of the manga, too bad the magazine added the author comment to almost ruin the mood.
One chapter left
This the best chapter of the whole series, Katou's plan was to wait for the aneourysm to tear then make the procedure.
Katou claiming the is the boss and then Asada taking command claiming he is her hound are amazing moments.
What a great chapter, Imagine reading this on the magazine and having to wait two weeks for the next chapter.
And 1 more thing, I love to see "team America" fail miserably
