If you enjoy a shallow story with characters that seem more like robots following a specific type of attitude from any anime you've seen that this manga is right for you.
the keyword this manga strives for is 'shock'. It wants to shock it viewers, and I can say that I'm honestly not shocked at all, I'm actually bored out of my mind. Which is surprising considering that every two pages you're going to find either gore or rape. But honestly, you've probably seen everything this manga has to offer from your friendly neighborhood fishy website. Head sliced in half, see it. Body stitching, seen it. Decapitation, seen it. It gets old real fast. You know what actually shocks viewers? actual horror.
Another unsurprising thing? That the characters as shallow as a puddle and just follow a specific attitude. You've seen it all folks, girl acting innocent but is sadistic, check. Girl acting joyful but is dark and cruel, check. Absolutely nothing of the main character that has nothing to offer but shitty reactions and doesn't provide any meaningful plot? Oh, you know it.
The idea of the story is pretty fun, but it delivers kinda flat. Either being too long or too short, even though it has tried to spice it up by having little twists here and there or some boring character arcs.
The art is actually kinda enjoyable, giving the character a certain charm. But even that gets worse as the chapters progress, getting more and more simple.
Overall the Manga is really boring, don't waste your time, read something else.
