you know, i always found it funny how they act like street thughs, street gang goons or mafia/yakuza wannabes, yet even a fat hobo would make a short work out of them.
It sure makes one wonder where yukkuris get such wannabe gangster mannerismn, specially when they are in the forest with no excuse of "i saw mister humans do it."
I guess it has something to do that they act the same way against other yukkuri's and work on them, passing the knowledge on their DNA or whatever they supposedly do, and the ones that do it on the humans never live enough to pass said knowledge.
yea i doubt it will be finished off as Cnaiur said. the 3 left panels imply this. they do it to show his level of frustration and what he is going to (as if we didn't know already, but the actions imply this in a cliffhanger sort of thing. you can just imagine a black frame that says YUPI~~
