The story did not paint a good picture in my head since the author didn’t describe much. He’ll say “she’s beautiful” and then doesn’t include any details about her whatsoever. And the action scenes were the same, no details.
And the protagonist, Ryo, is an emotionally erratic sociopath. One minute he’ll be grieving the pain he brought about and in the next breathe he’ll slaughter a couple of people he could have easily avoided.
