GMEM-131 Description

There was one researcher at a certain research institute who was slightly different from the others. He was extremely intelligent, and when it came to drugs, he was the best in Japan… no, actually, he was the best in the world. But one thing about him was that he had a strong hatred towards women. Such a man with a strong desire to conquer others… yes, that’s the story of Dr. Cruelty. He was a man who constantly felt inferior compared to other women. One day, he decided to conquer all the women in the world. He created a highly powerful aphrodisiac, and then joined forces with the evil organization called Black Lions Club. They decided to take on those bold and independent women. Soon after, Black Lions Club trapped Sweet Angel in a trap. The trapped woman was Saara, a girl whose name became well-known lately. She couldn’t move at all while being restrained. She tried to resist the newly developed aphrodisiac, but her body couldn’t withstand its effects. She was tortured by the men from Black Lions Club, and she ended up losing her self-awareness. What will become of this beautiful girl Saara?
