Youkou lives in a world where if a person gets cybernetic limb transplants, they run a risk of turning into a mindless killer called a Spider as a possible side effect. He has spent most of his time caring for his sister, who lost both her legs, and he learns the hard way how bad such a transformation can be. When his sister goes insane, a group calling themselves the Jackalopes come to save him.
I learned after reading this that Kataoka is the creator of Deadman Wonderland, which explains the creepy-cute and gory style. Our main villain, Kurama, seems over the top for me right now. GIANT breasts, bathing in human viscera… She might as well have “I’m Evil” tattooed on her massive chest. If gore isn’t your thing, you will not like this manga but so far I do like the characters and I want to know more about how the limbs are making people insane. 3.7 out of 5.
