Black Gate
Ordinary guy Kosaka always dreamed of having multiple girls competing for his attention. But he never imagined those fights would include swords and real physical harm! When Kosaka`s girlfriend Shizuka pulls a sword on his friend Kasumi, she means serious business. Sacrificing her body to the dark presence on the other side of her school`s black gate, Shizuka joins the dark side in a fight between good vs. evil.
As an average student, Kosaka always wondered what it would be like for girls to fight over him. But now his girlfriend Shizuka and his friend Kasumi are fighting over him...with swords. His school has a secret, a black gate that can only be opened by Shizuka and Kasumi, who each have a tattoo over one of their breasts. When Shizuka opens the gate and makes a deal with the evil creatures on the other side, Kosaka and all the other girls at his school are thrown into a deadly fight against evil.
