Trap of Blood is the story of an unloved, and often abused, orphan by the name of Ryuji Kiyama. His story begins in his home city of Osaka where, despite his genuine efforts to get along with his peers, he finds himself a constant source of ridicule by his classmates due to his very poor upbringing. Ryuji's foster mother is nothing short of a whore who routinely brings home men and openly copulates with them in front of him, and the closest thing he has to a father figure is a drunk construction warden who forces Ryuji to work the moment he gets back from school. Growing up in abject poverty, coupled with years of physical and mental abuse, ultimately prove too much for Ryuji to take and before long he sets about getting his own back on those that hurt him...
