Wait. If he just wanted to get to know her better, then why form a contract with her? And why the fuck would she let him control her after literally just meeting him a few minutes ago. My expectations were low but god damn.
I really love how this series emphasize that mob is just a kid and that its ok to leave the scary stuff to the adults. I wish other series do this more often.
@F-Radiation for the light novel. Sometimes manga adaptions of light novels are made for the sole purpose to advertise the novel. They usually only adapt the first volume of the novel.
