The concept is interesting and I was initially invested in seeing how the guild was formed and how Crow met all of the members, but the over-the-top, violent yandere reactions to literally everything got old very, very fast. I get it, it's a gag manga and yandere is the focus but, when the close ups of crazy eyes and women slashing and smashing monsters and other women takes up five out of every six panels there's not much to enjoy. It's a shame since there's the bones of a potentially good story beneath all of this shallow, ambiguous violence. Even the way the women in the guild react is pretty much the same, as well, which kills individualism and character development.
tl;dr, Might be amusing for people with a yandere kink but too shallow to really enjoy long term.
