So far I really like this!
The characters are interesting and appealing for what they are respectively, the plot is VERY much my thing and the art is good.
The only noticable flaw I find is that there are multiple moments in which a time skip of more than a brief moment is not really well established, so you can get confused wtf is going on since it can feel the scene is still in the same moment instead of minutes or hours passing between the two pannels. That could be done a little better. Other than that I can't find anything to critique so far.
Hopefully this'll turn out to be one of the great ones. It has lots of potentially, as long as the revenge doesn't drag too much and the next 'arc' for the plot can carry well enough just like the revenge arc.
