Not exactly a cliffhanger since she has Kids with the guy later... If this was shown first - the parents getting together and then the daughter being a yandere - then this would have the cliffhanger effect.
@Lelbrosa. Nah. 1st daughter is good at swordsmanship, 2nd is good at management. 3rd has to be a mage of some sorts, that's the usual progression, one child excels in one thing to the max and together they've cornered everything. She's probably a Sage.
Now, I get this is meant to be funny. But it does slightly grate on the nerves. She's pretty much just bullying him into following her. Still funny but I'd like to see some actual progress in their relationship. Like him finally understanding she thinks they're dating and he shuts her down along...
@Plippity. Exes? Perhaps someone that had an altercation with said people before and want to deal with them? I doubt this agency kills for fun, there's probably some kind of reason.
She really doesn't care about killing people other than her targets, does she. I'd expect someone to stalk their target and kill them when they're alone, this woman just kills the person and their friend.
Based on that girl's expression at the final panel on the last page, it seems she has some really personal reason for this rather than just entertainment, fame, or testing herself.
