Nice to meet you. I'm Iroha Hakata. I'm 20 years old. I'm a college student. The moment I first saw her, I was certain. This is... a rare talent. Beneath her refined baby face, there were bursting I-cup breasts that seemed mismatched for such a beautiful girl. The miraculous imbalance of "Beautiful Girl x Huge Boobs x Slender" became a hot topic instantly in last year's weekly magazine gravure, and she stood in the spotlight as the top candidate for the next big break. Now, this orthodox, peak-of-her-career gravure idol has joined S1 exclusively. Her AV ban is lifted. With her pure looks and a body of devastating power, why did she choose AV? With an overwhelming aura that heralds a "new era," she is set to change the industry. The story beyond gravure now begins.
