tbh, I really wanted a good backstory continuation for Kamui (like in the previous chapter) and a character development, but what I get...
I understand his love for his mom and all the efforts he had done, that he was a little kid, who wanted his mother to live no matter what. It's normal. But now Kamui hasn't changed at all, he still wants to kill his dad, despite having been saved from utsuro, and his reasons and motivation are quite unjustified.
So my opinion is that this is the worst Kamui chapter ever, Sorachi totally ruined him. -.-
