Angels Of Death Vol. 10

When she awakes in the cold basement of an abandoned building, 13-year-old Rachel (aka Ray) finds herself trapped with no memories and no idea where she is. Before long, she finds a cutthroat man named Zack completely covered in bandages and wielding a scythe. Somehow the two have become the targets of murderers living in the building. Forced to work together, the two begin their desperate search to find a way out before it’s too late.
In Vol. 10, Zack is forced to explore floor B1 alone after Ray passes out, and soon he begins to see that the floor’s traps and Ray’s condition are somehow linked, but in what way?
