They can also make "black ghosts" which kind of look like dark grey mummies that can only be seen by other demi-humans, unless they're about to kill regular humans. Only a few researchers know about the black ghosts (they call them IBMs), and all the security officers that were killed by the ghosts. They can follow orders, use weapons, and (best of all) fight each other.

At one point, demi-humans have a clandestine meeting. Two men organize it and five men show up. Not a single female, and there has been nothing in the story thus far to suggest that the demi-human-ness has any genetic component. Granted, the 2/20 percentages are more the norm for seinen manga, which this is, but it'd be nicer to see the numbers closer to 50/50. I know I'm not the target audience, but if you think I'm getting miffed over nothing, imagine this story with the gender percentages flipped. Pretty ridiculous, yeah? Same deal.
Sato takes on an entire SWAT team. They aren't using tranquilizer darts because of unnecessary plot reasons, but I'm willing to let that slide because of what follows. (spoilers) The SWAT guys just keep pumping bullets into Sato to keep him from ever fully coming back to life and shooting back. This only works for a few minutes before Sato uses his black ghost to take the hits for him and start taking out the boys in blue. Sato does a lot of awful stuff. But you can't help but like him for the methodical determination and skill with which he carries out his plans, always with a smile on his face.
I like where this series is going and the questions it asks about what happens when the social contract is rendered impotent by immortality. If you like Parasyte or Tokyo Ghoul, I bet you'll like this, so check it out.
