At the end of the day, the ones suffering are the ones alive. If Kana needed to slap him, let her. This is her way of grieving, and everybody grieves in their own way; there are no right or wrong ways of grieving. Even if this is disrespect, this is her way of moving on, and even Aqua wouldn't be hurt by it. We are no one to judge her, and we shouldn't anyway.
I was here from chap 8, and already knew this one was a banger and OOOOOOh this is the one, this is a REVENGE PLOT, gooood I love this manga I hope it will be animated ! I will miss it dearly...
